How to start up rsyslog automatically?

Question

Check current status of rsyslog

$ chkconfig --list rsyslog
rsyslog                   0:off  1:off  2:off  3:off  4:off  5:off  6:off

Start up rsyslog at some levels

$ sudo chkconfig --level 35 rsyslog on 

It outputs these information:

insserv: warning: script 'plymouth-stop' missing LSB tags and overrides
insserv: Default-Start undefined, assuming empty start runlevel(s) for script `plymouth-stop'
insserv: Default-Stop  undefined, assuming empty stop  runlevel(s) for script `plymouth-stop'
The script you are attempting to invoke has been converted to an Upstart
job, but lsb-header is not supported for Upstart jobs.
insserv: warning: script 'failsafe-x' missing LSB tags and overrides
insserv: Default-Start undefined, assuming empty start runlevel(s) for script `failsafe-x'
insserv: Default-Stop  undefined, assuming empty stop  runlevel(s) for script `failsafe-x'
The script you are attempting to invoke has been converted to an Upstart
job, but lsb-header is not supported for Upstart jobs.
insserv: warning: script 'udevtrigger' missing LSB tags and overrides
insserv: Default-Start undefined, assuming empty start runlevel(s) for script `udevtrigger'

Check current status of rsyslog again

$ chkconfig --list rsyslog
rsyslog                   0:off  1:off  2:off  3:off  4:off  5:off  6:off

I am a novice. Please show me how to use rsyslog from beginning.

Solution

As the output suggests the script was converted to an upstart job. So the best option right now is to open the file /etc/init/rsyslog.conf. You'll find a line start on there. Change this to

start on runlevel [35]

and save the file.

The command initctl list shows a list of of all init jobs and initctl show-config rsyslog will print out the status of rsyslog.
