<h1 id="shaarli-configuration">Shaarli configuration</h1>
<h2 id="foreword">Foreword</h2>
<p><strong>Do not edit configuration options in index.php! Your changes would be lost.</strong></p>
<p>Once your Shaarli instance is installed, the file <code>data/config.php</code> is generated:</p>
<ul>
<li>it contains all settings, and can be edited to customize values</li>
<li>its values override those defined in <code>index.php</code></li>
</ul>
<h2 id="file-and-directory-permissions">File and directory permissions</h2>
<p>The server process running Shaarli must have:</p>
<ul>
<li><code>read</code> access to the following resources:
<ul>
<li>PHP scripts: <code>index.php</code>, <code>application/*.php</code></li>
<li>3rd party PHP and Javascript libraries: <code>inc/*.php</code>, <code>inc\*.js</code></li>
<li>static assets:
<ul>
<li>CSS stylesheets: <code>inc\*.css</code></li>
<li><code>images\*</code></li>
</ul></li>
<li>RainTPL templates: <code>tpl\*.html</code></li>
</ul></li>
<li><code>read</code>, <code>write</code> and <code>execution</code> access to the following directories:
<ul>
<li><code>cache</code> - thumbnail cache</li>
<li><code>data</code> - link data store, configuration options</li>
<li><code>pagecache</code> - Atom/RSS feed cache</li>
<li><code>tmp</code> - RainTPL page cache</li>
</ul></li>
</ul>
<p>On a Linux distribution:</p>
<ul>
<li>the web server user will likely be <code>www</code> or <code>http</code> (for Apache2)</li>
<li>it will be a member of a group of the same name: <code>www:www</code>, <code>http:http</code></li>
<li>to give it access to Shaarli, either:
<ul>
<li>unzip Shaarli in the default web server location (usually <code>/var/www/</code>) and set the web server user as the owner</li>
<li>put users in the same group as the web server, and set the appropriate access rights</li>
</ul></li>
<li>if you have a domain / subdomain to serve Shaarli, <a href="Server-configuration">configure the server</a> accordingly<a href=".html"></a></li>
</ul>
