Ftp – vsftpd does not create pid file required for monit

ftpmonitmonitoringservice

I want to monitor vsftpd server from monit on CentOS 5.4 but somehow vsftpd does not create pid file in /var/run (nor in any other place).

Is this behavior normal for this distro?
How should I configure monit to watch for vsftpd, should I create pid file manually in /etc/init.d/vsftpd script?

Thanks.

You can try this: monit: check process without pidfile

check process vsftpd
 matching vsftpd
 start program = "/etc/init.d/vsftpd start"
 stop program = "/etc/init.d/vsftpd stop"

Alternatively you can follow the guide I put together using aforementioned init file. Created RPM to keep the system consistent across updates (via fpm). New init file has modified service name vsftpd-pid so you can keep vsftpd stopped and vsftpd-pid running.

Remember to change your monit start and stop commands too.

Monit not restarting service

You're on the right path that monit fails to start it because the PID file still exists.

I have ran into these problems before and the solution I used was to create an init script for the particular service, using something like /etc/init.d/skeleton (that's on debian) as a template (or rc.local), making sure a PID file is being created and deleted as appropriate (using start-stop-daemon et al).

I don't think there's really another solution as monit doesn't deal with deleting or creating PID files. Whichever script you use to start and stop the service, it needs to properly create and delete the PID files.

esac

Save it as /etc/init.d/vsftpd and try to start the daemon using it. If it fails to start, please return with log entry.

EDIT: I had modified the script. Seems that vsftpd ain't made for start-stop-daemon. And this time I had time to test it out, so is working.
