check_mk agent start by systemd Debian Jessie

I use check_mk everywhere.

For the old school, on Debian system you need install xinetd to start it.
But since we have systemd in Debian 8 Jessie, it will be much cleaner to do systemd way.

Here is how I do it:

1. Fist if you previous using xinetd, stop and remove it.



# service xinetd stop
# apt-get purge xinetd
Reading package lists... Done

The following packages were automatically installed and are no longer required:
  libfile-copy-recursive-perl libx265-79 update-inetd

Use 'apt-get autoremove' to remove them.
The following packages will be REMOVED:
  xinetd*
0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.
After this operation, 255 kB disk space will be freed.

And run autoremove to cleanup


# apt-get autoremove

2. Then check your check_mk agent version:

# dpkg -l|grep check-mk
ii  check-mk-agent                      1.2.8p12-1                        all          Check_MK Agent for Linux



3. Next enable the check_mk in systemd autostart.



# systemctl enable check_mk.socket
Created symlink from /etc/systemd/system/sockets.target.wants/check_mk.socket to /etc/systemd/system/check_mk.socket.



4. Finally start the service.



# systemctl start check_mk.socket


A special notice, because the systemd not allow the IP rules like xinetd does.
You will have to update your firewall to restrict other accessing.

Hope this helps, please let me know if you have any questions.
