Resolution

  1. Verify that permissions are set to 755 on /var/log directory (output truncated)

    $ ls -l /var/log
drwxr-x--- root  root  log   <============
drwxr-x--- redis redis redis
-rw-r----- redis redis redis.log

  2. Set the permissions to 755 on /var/log directory if output verification on step 1 shows incorrect permissions

    $ chmod 755 /var/log

  3. Validate permissions are now correct

    $ ls -ld /var/log
drwxr-xr-x. 1 root root 1230 Sep 16 08:54 /var/log

  4. Restart and check the service to ensure its active status

    $ satellite-maintain service restart
$ satellite-maintain service status

Root Cause

The /var/log directory permissions are set incorrectly.

Diagnostic Steps

  1. Check the /var/log/redis/redis.log for incorrectly set permissions:

    ls -l /var/log/redis/redis.log
-rw-r-----. 1 redis redis 456000 Dec 3 16:53 redis.log

  2. Check service status

    $ satellite-maintain service status
