title: Finding installed apache module versions in CentOS/RHEL
body: <p>I found a similar question about this but aimed at Debian <a href="https://stackoverflow.com/questions/3230733/how-can-i-check-apache-modules-version">here</a>.</p>
  
  <p>However since I don't have apt-cache it doesn't help me. Running:</p>
  
  <pre><code>    httpd -M
  </code></pre>
  
  <p>Gives me a list of all the installed modules but not their versions. My colleague has just pointed out that you can use:</p>
  
  <pre><code>    yum info mod_dav_svn.x86_64
  </code></pre>
  
  <p>This returns the installed version and the one available via Yum, however, if I use httpd -M it lists the names like:</p>
  
  <p>mod_proxy_http.so</p>
  
  <p>Is there any easy way to match up the installed modules file name (i.e. x86_64 i386) so I can check each module, or even better does anyone know of a way to output this info for all modules at once?</p>
