Stopping and Disabling Services in Linux

Things are a little different between Centos/RHEL6 and Centos/RHEL7 when it comes to starting and stopping services.

Having grown up on /etc/init.d/ scripts, it’s enough of a challenge using service blah stop instead of /etc/init.d/blah stop, but I guess service blah stop was added to Centos/RHEL6 to simplify things.

And then systemd comes alone they go and change it.  Way to go in terms of keeping things simple – even though it does bring some consistency across redhat and debian based distros going forward tbf…

Now it feels like every time I try to do something as simple as start and stop a service on a redhat based distro, Sod’s Law kicks in and I always get the command wrong, making me feel like a total noob, despite having rocked the command line for over 20 years.

As you can probably gather, I’m not a fan of the landscape changing (which is what drove me away from Windowz and into Linux in the first place – the longevity of the marketable skills set was better).  In my defence, Linus Torvalds isn’t that happy about it either.

Hence this little post.  A quick reminder on which command to use.  Now I’ve written it, I won’t need it of course.  Funny how the brain works, eh?

RHEL/CENTOS 6
chkconfig | grep zabbix – lists all services in all runlevels
chkconfig zabbix-agent off – toggle it on/off at startup
service zabbix-agent stop   -stop the service

RHEL/CENTOS 7
chkconfig
systemctl status zabbix-agent.service
systemctl disable zabbix-agent
systemctl stop zabbix-agent.service
