title: Why systemctl services are loaded but failed CentOS 7
body: <p>I finished to install Openstack Magnum service on CentOS 7, using this guide: <a href="http://docs.openstack.org/developer/magnum/install-guide-from-source.html" rel="nofollow noreferrer">http://docs.openstack.org/developer/magnum/install-guide-from-source.html</a></p>
  
  <p>Checking the magnum-api and magnum-conductor services after reboot shows that the services are active, but few seconds later they are in failed state. The selinux is disabled, and the services are enabled.</p>
  
  <p>Restarting the magnum api service:</p>
  
  <pre><code>[root@controller01 magnum]# systemctl restart magnum-api
  </code></pre>
  
  <p>magnum-api status OK:</p>
  
  <pre><code>[root@controller01 magnum]# systemctl status magnum-api
  ● magnum-api.service - OpenStack Magnum API Service

  <p>magnum-api service is failed after few seconds:</p>

  <p>Happens the same for the magnum-conductor service.</p>
  
  <p>How can I fix this?</p>
  
  <p>Thanks,
