Debian Linux has its own script to enable and disable services across
runlevels. It is called update-rc.d. Going by the above example, you
can enable apache webserver as follows:
# update-rc.d apache2 defaults
... this will enable the apache webserver to start in the default run
levels of 2,3,4 and 5. Of course, you can do it explicitly by giving
the run levels instead of the "defaults" keyword as follows:
# update-rc.d apache2 start 20 2 3 4 5 . stop 80 0 1 6 .
The above command modifies the sym-links in the respective /etc/rcX.d
directories to start or stop the service in the destined runlevels.
Here X stands for a value of 0 to 6 depending on the runlevel. One
thing to note here is the dot (.) which is used to terminate the set
which is important. Also 20 and 80 are the sequence codes which
decides in what order of precedence the scripts in the /etc/init.d/
directory should be started or stopped.
And to disable the service in all the run levels, you execute the command:
# update-rc.d -f apache2 remove
Here -f option which stands for force is mandatory.
But if you want to enable the service only in runlevel 5, you do this instead:
# update-rc.d apache2 start 20 5 . stop 80 0 1 2 3 4 6 .
