I have Tor installed on CentOS 6.6 x86_64 server that's also running cPanel.
The problem I'm having is that Tor doesn't appear to always be running. Is there a way to set it up to always start when the server starts and to keep it running?
Better question for Super User but you want to start up the service on boot. To do this for Centos checkout the chkconfig command where you should be able to apply chkconfig --add tor (or whatever the name of the tor service is called).
