 137  
 138      <ul>

 150          </li>
 151          <li><strong>PHP 5.3.3+</strong> and <strong>PHP < 7.0</strong> with support for the database you intend to use.</li>
 152          <li>The following PHP modules are required:

 185          <div class="content">
 186  
 187      <p>Installation of phpBB will vary according to your server and database. If you have <em>shell access</em> to your account (via telnet or ssh for example) you may want to upload the entire phpBB archive (in binary mode!) to a directory on your host and unarchive it there.</p>
 188  
 189      <p>If you do not have shell access or do not wish to use it, you will need to decompress the phpBB archive to a local directory on your system using your favourite compression program, e.g. winzip, rar, zip, etc. From there you must FTP <strong>ALL</strong> the files it contains (being sure to retain the directory structure and filenames) to your host. Please ensure that the cases of filenames are retained, do <strong>NOT</strong> force filenames to all lower or upper case as doing so will cause errors later.</p>
 190  
 191      <p>All .php, .sql, .cfg, .css, .js, .html, .htaccess and .txt files should be uploaded in <strong>ASCII</strong> mode, while all graphics should be uploaded in <strong>BINARY</strong> mode. If you are unfamiliar with what this means please refer to your FTP client documentation. In most cases this is all handled transparantly by your ftp client, but if you encounter problems later you should be sure the files were uploaded correctly as described here.</p>
 192  
 193      <p>phpBB comes supplied with British English as its standard language. However, a number of separate packs for different languages are available. If you are not a native English speaker you may wish to install one or more of these packages before continuing. The installation process below will allow you to select a default language from those available (you can, of course, change this default at a later stage). For more details on language packs, where to obtain them and how to install them please see the <a href="README.html#i18n">README</a>.</p>
 194  
 195      <p>Once all the files have been uploaded to your site, you should point your browser at this location with the addition of <code>/install/</code>. For example, if your domain name is <code>www.example.com</code> and you placed the phpBB files in the directory <code>/phpBB3</code> off your web root you would enter <code>http://www.example.com/phpBB3/install/</code> or (alternatively) <code>http://www.example.com/phpBB3/install/index.php</code> into your browser. When you have done this, you should see the <strong><em>phpBB Introduction</em></strong> screen appear.</p>
 196  
 197      <h4>Introduction:</h4>
 198  
 199      <p>The initial screen gives you a short introduction into phpBB. It allows you to read the license phpBB is released under (General Public License v2) and provides information about how you can receive support. To start the installation, use the <strong><em>INSTALL</em></strong> tab.</p>
 200  
 201      <h4>Requirements</h4>
 202  
 203      <p>The first page you will see after starting the installation is the Requirements list. phpBB automatically checks whether everything that it needs to run properly is installed on your server. You need to have at least the minimum PHP version installed, and at least one database available to continue the installation. Also important, is that all shown folders are available and have the correct permissions. Please see the description of each section to find out whether they are optional or required for phpBB to run. If everything is in order, you can continue the installation with <em>Start Install</em>.</p>
 204  
 205      <h4>Database settings</h4>
 206  
 207      <p>You now have to decide which database to use. See the <a href="#require">Requirements section</a> for information on which databases are supported. If you do not know your database settings, please contact your host and ask for them. You will not be able to continue without them. You need:</p>
 208  
 209      <ul>
 210          <li>The Database Type - the database you will be using.</li>
 211          <li>The Database server hostname or DSN - the address of the database server.</li>
 212          <li>The Database server port - the port of the database server (most of the time this is not needed).</li>
 213          <li>The Database name - the name of the database on the server.</li>
 214          <li>The Database username and Database password - the login data to access the database.</li>
 215      </ul>
 216  
 217      <div class="indent">
 218          <p><strong>Note:</strong> if you are installing using SQLite, you should enter the full path to your database file in the DSN field and leave the username and password fields blank. For security reasons, you should make sure that the database file is not stored in a location accessible from the web.</p>
 219      </div>
 220  
 221      <p>You don't need to change the Prefix for tables in database setting, unless you plan on using multipe phpBB installations on one database. In this case, you can use a different prefix for each installation to make it work.</p>
 222  
 223      <p>After you entered your details, you can continue with the <em>Proceed to next step</em> button. Now phpBB will check whether the data you entered will lead to a successful database connection and whether tables with the same prefix already exist.</p>
 224  
 225      <p>A <em>Could not connect to the database</em> error means that you didn't enter the database data correctly and it is not possible for phpBB to connect. Make sure that everything you entered is in order and try again. Again, if you are unsure about your database settings, please contact your host.</p>
 226  
 227      <p>If you installed another version of phpBB before on the same database with the same prefix, phpBB will inform you and you just need to enter a different database prefix.</p>
 228  
 229      <p>If you see the <em>Successful Connection</em> message, you can continue to the next step.</p>
 230  
 231      <h4>Administrator details</h4>
 232  
 233      <p>Now you have to create your administration user. This user will have full administration access and he/she will be the first user on your forum. All fields on this page are required. You can also set the default language of your forum on this page. In a vanilla phpBB installation, we only include British English. You can download further languages from <a href="https://www.phpbb.com/">www.phpbb.com</a>, and add them before installing or later.</p>
 234  
 235      <h4>Configuration file</h4>
 236  
 237      <p>In this step, phpBB will try to write the configuration file automatically. The forum needs the configuration file in order to operate. It contains all the database settings, so without it, phpBB will not be able to access the database.</p>
 238  
 239      <p>Usually, writing the configuration file automatically works fine. If the file permissions are not set correctly, this process can fail. In this case, you need to upload the file manually. phpBB asks you to download the <code>config.php</code> file and tells you what to do with it. Please read the instructions carefully. After you have uploaded the file, use <em>Done</em> to get to the last step. If <em>Done</em> returns you to the same page as before, and does not return a success message, you did not upload the file correctly.</p>
 240  
 241      <h4>Advanced settings</h4>
 242  
 243      <p>The Advanced settings allow you to set additional parameters of the board configuration. They are optional and you can always change them later. So, even if you are not sure what these settings mean, you can still proceed to the final step and finish the installation.</p>
 244  
 245      <p>If the installation was successful, you can now use the <em>Login</em> button to visit the Administration Control Panel. Congratulations, you have installed phpBB successfully. But there is still work ahead!</p>
 246  
 247      <p>If you are unable to get phpBB installed even after reading this guide, please look at the support section of the installer's introduction page to find out where you can ask for further assistance.</p>
 248  
 249      <p>At this point if you are converting from phpBB 2.0.x, you should refer to the <a href="#convert">conversion steps</a> for further information. If not, you should remove the install directory from your server as you will only be able to access the Administration Control Panel whilst it is present.</p>

 260      <a name="update"></a><h2>4. Updating from stable releases of phpBB 3.1.x</h2>
 261  
 262      <div class="paragraph">
 263          <div class="inner">
 264  
 265          <div class="content">
 266  
 267  <p>If you are currently using a stable release of phpBB, updating to this version is straightforward. You would have downloaded one of four packages and your choice determines what you need to do. <strong>Note</strong>: Before updating, we heavily recommend you do a <em>full backup of your database and existing phpBB files</em>! If you are unsure how to achieve this please ask your hosting provider for advice.</p>
 268  
 269  <p><strong>Please make sure you update your phpBB source files too, even if you run the <code>database_update.php</code> file.</strong> If you have shell access to your server, you may wish to update via the command line interface. From your board's root, execute the following command: <code>php bin/phpbbcli.php --safe-mode db:migrate</code>.</p>
 270  
 271  <a name="update_full"></a><h3>4.i. Full package</h3>
 272  
 273      <p>The full package is normally meant for new installations only, but if you want to replace all source files, this package comes in handy.</p>
 274  
 275      <p>First, you should make a copy of your existing <code>config.php</code> file; keep it in a safe place! Next, delete all the existing phpBB files, you may want to leave your <code>files/</code> and <code>images/</code> directories in place. You can leave alternative styles in place too. With this complete, you can upload the new phpBB files (see <a href="#install">New installation</a> for details if necessary). Once complete, copy back your saved <code>config.php</code>, replacing the new one. Another method is to just <strong>replace</strong> the existing files with the files from the full package - though make sure you do <strong>not</strong> overwrite your config.php file.</p>
 276  
 277      <p>You should now run <code>install/database_update.php</code> which, depending on your previous version, will make a number of database changes. You may receive <em>FAILURES</em> during this procedure. They should not be a cause for concern unless you see an actual <em>ERROR</em>, in which case the script will stop (in this case you should seek help via our forums or bug tracker). If you have shell access to your server, you may wish to update via the command line interface. From your board's root, execute the following command: <code>php bin/phpbbcli.php --safe-mode db:migrate</code>.</p>
 278  
 279      <p>Once <code>install/database_update.php</code> has completed, you may proceed to the Administration Control Panel and then remove the install directory as advised.</p>
 280  
 281  <a name="update_files"></a><h3>4.ii. Changed files</h3>
 282  
 283      <p>This package is meant for those wanting to only replace the files that were changed between a previous version and the latest version.</p>
 284  
 285      <p>This package contains a number of archives, each contains the files changed from a given release to the latest version. You should select the appropriate archive for your current version, e.g. if you currently have <strong>3.1.0</strong> you should select the appropriate <code>phpBB-3.1.1-files.zip/tar.bz2</code> file.</p>
 286  
 287      <p>The directory structure has been preserved, enabling you (if you wish) to simply upload the uncompressed contents of the archive to the appropriate location on your server, i.e. simply overwrite the existing files with the new versions. Do not forget that if you have installed any modifications (MODs) these files will overwrite the originals, possibly destroying them in the process. You will need to re-add MODs to any affected file before uploading.</p>
 288  
 289      <p>As for the other update procedures, you should run <code>install/database_update.php</code> after you have finished updating the files. This will update your database schema and increment the version number. If you have shell access to your server, you may wish to update via the command line interface. From your board's root, execute the following command: <code>php bin/phpbbcli.php --safe-mode db:migrate</code>.</p>
 290  
 291  <a name="update_patch"></a><h3>4.iii. Patch file</h3>
 292  
 293      <p>The patch file package is for those wanting to update through the patch application, and should only be used by those who are comfortable with it.</p>
 294  
 295      <p>The patch file is one solution for those with many Modifications (MODs) or other changes and do not want to re-add them back to all the changed files. To use this you will need command line access to a standard UNIX type <strong>patch</strong> application. If you do not have access to such an application, but still want to use this update approach, we strongly recommend the <a href="#update_auto">Automatic update package</a> explained below. It is also the recommended update method.</p>
 296  
 297      <p>A number of patch files are provided to allow you to update from previous stable releases. Select the correct patch, e.g. if your current version is <strong>3.1.0</strong>, you need the <code>phpBB-3.1.1-patch.zip/tar.bz2</code> file. Place the correct patch in the parent directory containing the phpBB core files (i.e. index.php, viewforum.php, etc.). With this done you should run the following command: <code>patch -cl -d [PHPBB DIRECTORY] -p1 &lt; [PATCH NAME]</code> (where PHPBB DIRECTORY is the directory name your phpBB Installation resides in, for example phpBB, and where PATCH NAME is the relevant filename of the selected patch file). This should complete quickly, hopefully without any HUNK FAILED comments.</p>
 298  
 299      <p>If you do get failures, you should look at using the <a href="#update_files">Changed Files</a> package to replace the files which failed to patch. Please note that you will need to manually re-add any MODs to these particular files. Alternatively, if you know how, you can examine the .rej files to determine what failed where and make manual adjustments to the relevant source.</p>
 300  
 301      <p>You should, of course, delete the patch file (or files) after use. As for the other update procedures, you should run <code>install/database_update.php</code> after you have finished updating the files. This will update your database schema and data (if appropriate) and increment the version number. If you have shell access to your server, you may wish to update via the command line interface. From your board's root, execute the following command: <code>php bin/phpbbcli.php --safe-mode db:migrate</code>.</p>
 302  
 303  <a name="update_auto"></a><h3>4.iv. Automatic update package</h3>
 304  
 305      <p>This update method is the recommended method for updating. This package detects changed files automatically and merges in changes if needed.</p>
 306  
 307      <p>The automatic update package will update the board from a given version to the latest version. A number of automatic update files are available, and you should choose the one that corresponds to the version of the board that you are currently running. For example, if your current version is <strong>3.1.5</strong>, you need the <code>phpBB-3.1.5_to_3.1.6.zip/tar.bz2</code> file.</p>
 308  
 309      <p>To perform the update, either follow the instructions from the <strong>Administration Control Panel-&gt;System</strong> Tab - this should point out that you are running an outdated version and will guide you through the update - or follow the instructions listed below.</p>
 310  
 311      <ul>
 312          <li>Go to the <a href="https://www.phpbb.com/downloads/">downloads page</a> and download the latest update package listed there, matching your current version.</li>
 313          <li>Upload the uncompressed archive contents to your phpBB installation - only the <code>install/</code> and <code>vendor/</code> folders are required. Upload these folders in their entirety, retaining the file structure.</li>
 314          <li>After the install folder is present, phpBB will go offline automatically.</li>
 315          <li>Point your browser to the install directory, for example <code>http://www.example.com/phpBB3/install/</code></li>
 316          <li>Choose the "Update" Tab and follow the instructions</li>
 317      </ul>
 318  
 319      <p>&nbsp;</p>
 320  
 321  <a name="update_all"></a><h3>4.v. All package types</h3>
 322  
 323      <p>If you have non-English language packs installed, you may want to see if a new version has been made available. A number of missing strings may have been added which, though not essential, may be beneficial to users. Please note that at this time not all language packs have been updated so you should be prepared to periodically check for updates.</p>
 324  
 325      <p>These update methods will only update the standard styles, <code>prosilver</code> and <code>subsilver2</code>, any other styles you have installed for your board will usually also need to be updated.</p>

 376  
 377  <p>This paragraph explains the steps necessary to convert your existing phpBB2 installation to phpBB3.</p>
 378  
 379  <a name="prereq"></a><h3>5.i. Requirements before converting</h3>
 380  
 381      <p>Before converting, we heavily recommend you do a <em>full backup of your database and files</em>! If you are unsure how to achieve this, please ask your hosting provider for advice. You basically need to follow the instructions given for <a href="#install">New installations</a>. Please <strong>do not</strong> overwrite any old files - install phpBB3 at a different location.</p>
 382  
 383      <p>Once you made a backup of everything and also have a brand new phpBB3 installation, you can now begin the conversion.</p>
 384  
 385      <p>Note that the conversion requires <code>CREATE</code> and <code>DROP</code> privileges for the phpBB3 database user account.</p>
 386  
 387  <a name="conversion"></a><h3>5.ii. Converting</h3>
 388  
 389      <p>To begin the conversion, visit the <code>install/</code> folder of your phpBB3 installation (the same as you have done for installing). Now you will see a new tab <em>Convert</em>. Click this tab.</p>
 390  
 391      <p>As with install, the conversion is automated. Your previous 2.0.x database tables will not be changed and the original 2.0.x files will remain unaltered. The conversion is actually only filling your phpBB3 database tables and copying additional data over to your phpBB3 installation. This has the benefit that if something goes wrong, you are able to either re-run the conversion or continue a conversion, while your old board is still accessible. We really recommend that you disable your old installation while converting, else you may have inconsistent data after the conversion.</p>
 392  
 393      <p>Please note that this conversion process may take quite some time and depending on your hosting provider this may result in it failing (due to web server resource limits or other timeout issues). If this is the case, you should ask your provider if they are willing to allow the convert script to temporarily exceed their limits (be nice and they will probably be quite helpful). If your host is unwilling to increase the limits to run the convertor, please see this article for performing the conversion on your local machine: <a href="https://www.phpbb.com/kb/article/offline-conversions/">Knowledge Base - Offline Conversions</a></p>
 394  
 395      <p>Once completed, your board should be immediately available. If you encountered errors, you should report the problems to our bug tracker or seek help via our forums (see <a href="README.html">README</a> for details).</p>
 396  
 397  <a name="postreq"></a><h3>5.iii. Things to do after conversion</h3>
 398  
 399      <p>After a successful conversion, there may be a few items you need to do - apart from checking if the installation is accessible and everything displayed correctly.</p>
 400  
 401      <p>The first thing you may want to do is to go to the administration control panel and check every configuration item within the general tab. Thereafter, you may want to adjust the forum descriptions/names if you entered HTML there. You also may want to access the other administrative sections, e.g. adjusting permissions, smilies, icons, ranks, etc.</p>
 402  
 403      <p>During the conversion, the search index is not created or transferred. This means after conversion you are not able to find any matches if you want to search for something. We recommend you rebuild your search index within <strong>Administration Control Panel -&gt; Maintenance -&gt; Database -&gt; Search Index</strong>.</p>
 404  
 405      <p>After verifying the settings in the ACP, you can delete the install directory to enable the board. The board will stay disabled until you do so.</p>
 406  
 407      <p>Once you are pleased with your new installation, you may want to give it the name of your old installation, changing the directory name. With phpBB3 this is possible without any problems, but you may still want to check your cookie settings within the administration panel; in case your cookie path needs to be adjusted prior to renaming.</p>
 408  
 409  <a name="convprob"></a><h3>5.iv. Common conversion problems</h3>
 410  
 411      <p><strong>Broken non-latin characters</strong> The conversion script assumes that the database encoding in the source phpBB2 matches the encoding defined in the <code>lang_main.php</code> file of the default language pack of the source installation. Edit that file to match the database's encoding and re-start the conversion procedure.</p>
 412  
 413      <p><strong>http 500 / white pages</strong> The conversion is a load-heavy procedure. Restrictions imposed by some server hosting providers can cause problems. The most common causes are: values too low for the PHP settings <code>memory_limit</code> and <code>max_execution_time</code>. Limits on the allowed CPU time are also a frequent cause for such errors, as are limits on the number of database queries allowed. If you cannot change such settings, then contact your hosting provider or run the conversion procedure on a different computer. The phpBB.com forums are also an excellent location to ask for support.</p>
 414  
 415      <p><strong>Password conversion</strong> Due to the utf-8 based handling of passwords in phpBB3, it is not always possible to transfer all passwords. For passwords "lost in translation" the easiest workaround is to use the <em>I forgot my password</em> link on the login page.</p>
 416  
 417      <p><strong>Path to your former board</strong> The convertor expects the relative path to your old board's files. So, for instance, if the old board is located at <code>http://www.yourdomain.com/forum</code> and the phpBB3 installation is located at <code>http://www.yourdomain.com/phpBB3</code>, then the correct value would be <code>../forum</code>. Note that the webserver user must be able to access the source installation's files.</p>
 418  
 419      <p><strong>Missing images</strong> If your default board language's language pack does not include all images, then some images might be missing in your installation. Always use a complete language pack as default language.</p>
 420  
 421      <p><strong>Smilies</strong> During the conversion you might see warnings about image files where the copying failed. This can happen if the old board's smilies have the same file names as those on the new board. Copy those files manually after the conversion, if you want to continue using the old smilies.</p>

 437  
 438          <div class="content">
 439  
 440      <p>Once you have successfully installed phpBB you <strong>MUST</strong> ensure you remove the entire <code>install/</code> directory. Leaving the install directory in place is a <em>very serious potential security issue</em> which may lead to deletion or alteration of files, etc. Please note that until this directory is removed, phpBB will not operate and a warning message will be displayed. Beyond this <strong>essential</strong> deletion, you may also wish to delete the docs/ directory if you wish.</p>
 441  
 442      <p>With these directories deleted, you should proceed to the administration panel. Depending on how the installation completed, you may have been directed there automatically. If not, login as the administrator you specified during install/conversion and click the <strong>Administration Control Panel</strong> link at the bottom of any page. Ensure that details specified on the <strong>General</strong> tab are correct!</p>
 443  
 444  <a name="avatars"></a><h3>6.i. Uploadable avatars</h3>
 445  
 446      <p>phpBB supports several methods for allowing users to select their own <em>avatar</em> (an avatar is a small image generally unique to a user and displayed just below their username in posts).</p>
 447  
 448      <p>Two of these options allow users to upload an avatar from their machine or a remote location (via a URL). If you wish to enable this function you should first ensure the correct path for uploadable avatars is set in <strong>Administration Control Panel -&gt; General -&gt; Board Configuration -&gt; Avatar settings</strong>. By default this is <code>images/avatars/uploads</code>, but you can set it to whatever you like, just ensure the configuration setting is updated. You must also ensure this directory can be written to by the webserver. Usually this means you have to alter its permissions to allow anyone to read and write to it. Exactly how you should do this depends on your FTP client or server operating system.</p>
 449  
 450      <p>On UNIX systems, for example, you set the directory to a+rwx (or ugo+rwx or even 777). This can be done from a command line on your server using chmod or via your FTP client (using the Change Permissions, chmod or other Permissions dialog box, see your FTP client's documentation for help). Most FTP clients list permissions in the form of User (Read, Write, Execute), Group (Read, Write, Execute) and Other (Read, Write, Execute). You need to tick all of these boxes to set correct permissions.</p>
 451  
 452      <p>On Windows systems, you need to ensure the directory is not write-protected and that it has global write permissions (see your server's documentation or contact your hosting provider if you are unsure on how to achieve this).</p>
 453  
 454      <p>Please be aware that setting a directory's permissions to global write access is a potential security issue. While it is unlikely that anything nasty will occur (such as all the avatars being deleted) there are always people out there to cause trouble. Therefore you should monitor this directory and if possible make regular backups.</p>
 455  
 456  <a name="webserver_configuration"></a><h3>6.ii. Webserver configuration</h3>
 457  
 458      <p>Depending on your web server, you may have to configure your server to deny web access to the <code>cache/</code>, <code>files/</code>, <code>store/</code> and other directories. This is to prevent users from accessing sensitive files.</p>
 459  
 460      <p>For <strong>Apache</strong> there are <code>.htaccess</code> files already in place to do this for you. Similarly, for <strong>Windows</strong> based servers using <strong>IIS</strong> there are <code>web.config</code> files already in place to do this for you. For other webservers, you will have to adjust the configuration yourself. Sample files for <strong>nginx</strong> and <strong>lighttpd</strong> to help you get started may be found in <code>docs/</code> directory.</p>
