WowzaStreamingEngineManager as a non root user

Wowza Streaming Engine

Hi all,

Is it possible to run the WowzaStreamingEngineManager service as a non root user?

I have tried editing /etc/init.d/WowzaStreamingEngineManager and placing sudo -u user in front of $WMSMGRDAEMON_CMD in the start section.

These errors appeared in the log when attempting to start and the service start command did not return:

/usr/local/WowzaStreamingEngine/manager/bin/startmgr.sh: line 17: ulimit: open files: cannot modify limit: Operation not permitted

/usr/local/WowzaStreamingEngine/manager/bin/startmgr.sh: line 54: /var/run/WowzaStreamingEngineManager.pid: Permission denied

I guess more modifications could be made to resolve these two issues. Are there instructions available for running WowzaStreamingEngineManager as a non root user?

Thanks!

Hi Dennis

For the Streaming Engine Manager to run as a non-root user you could look at modifying the startmgr.sh script in /usr/local/WowzaStreamingEngine/manager/bin (default location). The following is a quick test I carried out which started up the Manager as a non-root user.

Please note that this is not a supported or documented solution. I will however feed this into our backlog queue, but we can’t give any commitment for when a request will be implemented and supported.

Find the block of code like this:

 if [ "$WMSMGRCOMMAND" = "start" ]; then
           $RUNCMD $CMD $BACKGRND &
        else
           $CMD
        fi

Modify the line beginning $RUNCMD to the following:

 if [ "$WMSMGRCOMMAND" = "start" ]; then
            sudo -u $USER-g $GROUP $CMD $BACKGRND &
        else
           $CMD
        fi

You will of course need to replace the $USER and $GROUP variables with your non-root user/group. You will also need to ensure that this user has permission to access the files within [install-dir]/manager/ and that the various lock and pid files are writable, but the basics are there to get something quickly up and running.
