Close at the specified level

You can also turn off 345.

Test:

Start the SSHD service at level 3

Found that there was a k25sshd file produced

And at level 3, it's closed.

Delete this soft link file k25sshd

Re-create a new soft link file called S55sshd file

Look again, sshd turned into a 3-level launch.

[[email protected] 16:43:39] #ll/etc/rc.d/rc3.d/| grep "Sshd"

lrwxrwxrwx 1 root root from Oct 3 14:46 s55sshd. /init.d/sshd
