Below is a list of directories and log files to help you diagnose problems with specific applications:
- The
/var/lib/openshift/gear_UUID
directory on the node host is the home directory for each application gear. Check the SELinux contexts. - The
/var/lib/openshift/.httpd.d/gear_UUID*
directory on the node host is the operations directory for each application gear. It contains thehttpd
configuration for that particular application gear. - The
/var/log
directory on the node host contains theruby193-mcollective.log
file. - Searching the
/var/log/openshift
directory on the node host for the gear's user UUID usinggrep
could help you find problems with application gears that generate error messages. - The
/var/log/openshift/user_action.log
