| <h1>Installation Instructions<a class="headerlink" href="#installation-instructions" title="Permalink to this headline">¶</a></h1> |
| <p>CodeIgniter is installed in four steps:</p> |
| <ol class="arabic simple"> |
| <li>Unzip the package.</li> |
| <li>Upload the CodeIgniter folders and files to your server. Normally the |
| <em>index.php</em> file will be at your root.</li> |
| <li>Open the <em>application/config/config.php</em> file with a text editor and |
| set your base URL. If you intend to use encryption or sessions, set |
| your encryption key.</li> |
| <li>If you intend to use a database, open the |
| <em>application/config/database.php</em> file with a text editor and set your |
| database settings.</li> |
| </ol> |
| <p>If you wish to increase security by hiding the location of your |
| CodeIgniter files you can rename the system and application folders to |
| something more private. If you do rename them, you must open your main |
| <em>index.php</em> file and set the <code class="docutils literal"><span class="pre">$system_path</span></code> and <code class="docutils literal"><span class="pre">$application_folder</span></code> |
| variables at the top of the file with the new name you’ve chosen.</p> |
| <p>For the best security, both the system and any application folders |
| should be placed above web root so that they are not directly accessible |
| via a browser. By default, <em>.htaccess</em> files are included in each folder |
| to help prevent direct access, but it is best to remove them from public |
| access entirely in case the web server configuration changes or doesn’t |
| abide by the <em>.htaccess</em>.</p> |
| <p>If you would like to keep your views public it is also possible to move |
| the views folder out of your application folder.</p> |
| <p>After moving them, open your main index.php file and set the |
| <code class="docutils literal"><span class="pre">$system_path</span></code>, <code class="docutils literal"><span class="pre">$application_folder</span></code> and <code class="docutils literal"><span class="pre">$view_folder</span></code> variables, |
| preferably with a full path, e.g. ‘<em>/www/MyUser/system</em>’.</p> |
| <p>One additional measure to take in production environments is to disable |
| PHP error reporting and any other development-only functionality. In |
| CodeIgniter, this can be done by setting the <code class="docutils literal"><span class="pre">ENVIRONMENT</span></code> constant, which |
| is more fully described on the <a class="reference internal" href="../general/security.html"><span class="doc">security |
| page</span></a>.</p> |
| <p>That’s it!</p> |
| <p>If you’re new to CodeIgniter, please read the <a class="reference internal" href="../overview/getting_started.html"><span class="doc">Getting |
| Started</span></a> section of the User Guide |
| to begin learning how to build dynamic PHP applications. Enjoy!</p> |
