			<content:encoded><![CDATA[<p>It sucks when server disks fill up.  I have <a href="http://www.nagios.org/">Nagios</a> set up to notify me well before it&#8217;s a problem, but it happens annoyingly frequently, and it&#8217;s always the same cause:  log files.</p>

<p>Symfony&#8217;s production environments don&#8217;t create logs, but the development environments do, and for one project I had several batch jobs logging to the <var>myproject/log</var> directory.  (Troubleshooting batch jobs without logs is just crazy).</p>

<p>I was going to use <a href="http://www.symfony-project.org/book/1_2/16-Application-Management-Tools#chapter_16_sub_symfony_logs"><code>symfony log:rotate</code></a>, but</p>

<ul>
<li>I would need one cron job for each log</li>
<li>I had permission issues since some of the logs belong to <var>apache</var> and others to <var>root</var></li>
<li>Everything else on the machine, pretty much, is managed with the standard Linux utility <a href="http://linux.die.net/man/8/logrotate"><var>logrotate</var></a>.  Logrotate has been around for about 174 Linux Years, and is common to most distributions.</li>
</ul>

<p>So here&#8217;s how I did it using with <var>logrotate</var>.</p>

<p><span id="more-282"></span></p>

<ol>

    <li><strong>WARNING</strong>:  You might want to make a convenient copy of your log directory before you do this.  I accidently wiped all the logs out while messing with it.
</li>

    <li>Create a file <var>config/myproject.logrotate</var>.  Very simple, I just want it to use the same rotation schedule specified for the whole machine in <var>/etc/logrotate.conf</var>


<div class="wp_syntax"><div class="code"><pre class="bash"><span class="sy0">/</span>path<span class="sy0">/</span>to<span class="sy0">/</span>myproject<span class="sy0">/</span>log<span class="sy0">/*</span>.log <span class="br0">&#123;</span>
        weekly
        rotate <span class="nu0">4</span>
<span class="br0">&#125;</span></pre></div></div>



</li>

    <li>Check that it will do stuff by running it with the debug flag


<div class="wp_syntax"><div class="code"><pre class="bash">logrotate <span class="re5">-df</span> config<span class="sy0">/</span>badge.logrotate</pre></div></div>


</li>


    <li>Make a symlink to it in <var>/etc/logrotate.d</var>


<div class="wp_syntax"><div class="code"><pre class="bash"><span class="kw2">ln</span> <span class="re5">-s</span> <span class="sy0">/</span>path<span class="sy0">/</span>to<span class="sy0">/</span>myproject<span class="sy0">/</span>config<span class="sy0">/</span>myproject.logrotate  <span class="sy0">/</span>etc<span class="sy0">/</span>logrotate.d<span class="sy0">/</span>myproject</pre></div></div>



</li>

    <li>Run it the first time manually to rotate your logs and make sure it does the right thing!


<div class="wp_syntax"><div class="code"><pre class="bash"><span class="kw2">sudo</span> logrotate <span class="re5">-fv</span> <span class="sy0">/</span>etc<span class="sy0">/</span>logrotate.d<span class="sy0">/</span>myproject</pre></div></div>



</li>
</ol>
