title: jfrog-xray fails to start (fresh installation)
body: <p>I'm in the process of installing jfrog-xray (version 2.8.6) on redhat.</p>
  
  <p>I have followed the installation instructions for installing to bare metal (compared to docker) and the install seems to have gone fine. </p>
  
  <p>However, when trying to start all the services, it appears that none of them get off the ground.</p>
  
  <p>The following is what the ./xray.sh satus command produces:</p>
