title: Installing openCPU with exotic path to Apache
body: <p>I am installing OpenCPU on a production RedHat 7 Server and it turned out that the path to their Apache server is not </p>
  
  <pre><code>/etc/httpd 
  </code></pre>
  
  <p>but something else.
  Apparently, OpenCPU was still referring to /etc/httpd and therefore did not work.
  I am wondering if there is a way to specify custom path to Apache server for OpenCPU installation (as a parameter for installation, or somewhere in the code, or after installation)?</p>
  
  <p>OpenCPU version is 2.0.7, RedHat version is 7.3, Apache server version is 2.4</p>
