I'm trying to setup multiple instances of rsyslog (one for kernel
messages) using lfs-bootscripts-20120116 and running into some
problems.
I'm using rsyslogd 5.8.6, which is designed with multiple instance
support. I've set up one configuration file (/etc/rsysklog.conf)
for the kernel logger and one for the system logger (/etc/rsyslog.conf)
rsyslogd's
-i flag specifies the pid file used and
-f specifies the configuration file.
> root:~# source /lib/lsb/init-functions
>
> root:~# start_daemon -p /run/rsyslogd.pid /sbin/rsyslogd -i /run/rsyslogd.pid
> -f /etc/rsyslog.conf
> root:~# echo $?
> 0
Now let's check:
> root:~# ps xa | grep rsyslogd
> 8045 ? Sl 0:00 /sbin/rsyslogd -i /run/rsyslogd/pid -f
> /etc/rsyslog.conf
> 8131 tty1 s+ 0:00 grep rsyslog
>
> root:~# stausproc -p /run/rsyslogd.pid /rsbin/rsyslogd
> rsyslogd is running with Process ID(s) 8045
>
> root:# cat /run/rsyslogd.pid
> 8045
So far so good.
But now let's try running the second instance.
> root:~# start_daemon -p /run/rsysklogd.pid /sbin/rsyslogd -i
> /run/rsysklogd.pid -f /etc/rsysklog.conf
> root:~# echo $?
> 0
and now check:
> root:~# ps xa | grep rsyslogd
> 8045 ? Sl 0:00 /sbin/rsyslogd -i /run/rsyslogd.pid -f
> /etc/rsyslog.conf
> 8133 tty1 s+ 0:00 grep rsyslog
What?
Note that rsyslog behaves as expected:
> root:~# sbin/rsyslogd -i /run/rsysklogd.pid -f /etc/rsysklog.conf
> root:~# echo $?
> 0
>
> root:~# ps xa | grep rsyslogd
> 8045 ? Sl 0:00 /sbin/rsyslogd -i /run/rsyslogd.pid -f
> /etc/rsyslog.conf
> 8149 ? Sl 0:00 /sbin/rsyslogd -i /run/rsysklogd.pid -f
> /etc/rsysklog.conf
> 8155 tty1 s+ 0:00 grep rsyslog
>
> root:~# cat /run/rsyslogd.pid
> 8045
> root:~# cat /run/rsysklogd.pid
> 8149
So far, I think I've tracked the problem down to statusproc() not correctly
using the pidfile it's given.
Namely: this is correct
> root:~# statusproc -p /run/rsyslogd.pid /sbin/rsyslogd
> rsyslogd is running with Process ID(s) 8045
>
> root:~# cat /run/rsyslogd.pid
> 8045
But this is not
> root:~# statusproc -p /run/rsysklogd.pid /sbin/rsyslogd
> rsyslogd is running with Process ID(s) 8045
>
> root:~# cat /run/rsysklogd.pid
> 8149
BTW: statusproc() defined in /lib/lsb/init-functions has an "exit 1" just after
it prints its Usage statement; shouldn't this be a "return 1" instead?
BTW2: statusproc()'s Usage statement says :
echo "Usage: [-p pidfile] statusproc {program}"
Shouldn't this be this?
echo "Usage: statusproc [-p pidfile] {program}"
