OpsCenter cannot start up 

Steps to take when OpsCenter cannot start up due to improper directory permissions.

OpsCenter uses the system temporary directory to load/execute dynamic class files. You may see an error message in the startup.log indicating that OpsCenter cannot read/write/execute from that directory. If permissions on the directory cannot be changed, you can use a JVM argument to change the temporary directory that OpsCenter uses. Please refer to the JVM Tuning section for more details.

startup.log 

The location of the startup.log file depends on the type of installation:

  • Package installations: /var/log/opscenter/startup.log
  • Tarball installations: install_location/opscenterd/log/startup.log
