chkconfig

Overview

chkconfig is this sweet program that keeps track of all the init scripts that run at boot. For details on what runlevels and such these programs run at, check out my runlevels overview.

Here's my current chkconfig and what i need to make changes too.

ypbind          0:off   1:off   2:off   3:off   4:off   5:off   6:off

So check out sshd on this list:

sshd            0:off   1:off   2:on    3:on    4:on    5:on    6:off

This tells us that when it starts up, it runs on level 2345 (levels 2 and 3 and 4 and 5); on multi-user mode without networking (2), on multi-user mode with networking (3), on a user defined run-level (4), and on multi-user mode with x and console (5).

whereas nagios:

nagios          0:off   1:off   2:off   3:off   4:off   5:off   6:off

Is pretty much disabled at boot. This means I would have to manually turn it on each time i need it. That's not a great synario as nagios is monitoring software for the other computers on the network, so it needs to be running whenever the server is on. So I will change my chkconfig to allow it to run (pretty much on the same levels as sshd).

[jocasta] ~ > chkconfig --level 2345 nagios
[jocasta] ~ >

And now when i run chkconfig again, it prints:

nagios            0:off   1:off   2:on    3:on    4:on    5:on    6:off

You can do the same thing to turn off a service, or to add a service simply use –add with chkconfig.
