  <p>phpinfo() shows that my site has a version of php 5.6. All right!</p>
  
  <p>Now I am trying to restrict the rights with Mod_Ruid2. I added the following to my virtual host</p>
  
  <pre><code>RDocumentChRoot /var /www/html
  &lt;Directory "/www/html/"&gt;
          Require all granted
          RMode config
          RUidGid admin0 admin0
  &lt;/Directory&gt;
  </code></pre>
  
  <p>after trying to get to the site I see an error in the logs</p>
  
  <pre><code>[Sun Oct 13 16:09:02.492117 2019] [proxy:error] [pid 13571] (2)No such file or directory: AH02454: FCGI: attempt to connect to Unix domain socket /var/run/php/php5.6-fpm.sock (*) failed
