Re: [Kea-users] Auto start

Hi Todd!

I've tried to do the same thing. I tried to adapt Kea to systemd but I was 
unable to get satisfying results using keactrl so I opted to skip that step and 
run the services directly and I wrote a service file for each one. I also 
changed the logger configuration to output all logging information to /dev/log 
and let journald handle it, allowing me to use the features of journald. The 
Kea services expect logger_lockfile to exist even if the logger has been 
configured to just print to /dev/log, so I added two ExecStartPre commands.

Kea shouldn't handle the logging, it should let syslogd or journald handle it, 
they both use the same interface and is compatible with both BSD and Linux. If 
you have journald (I believe that all distrubutions with systemd do) then I 
recommend that you take advantage of it by pointing the output in the logger 
configuration in kea.conf to /dev/log. For anyone who doesn't use journald then 
I highly recommend that you also configure the logging daemon to put the output 
of kea into separate log files which is a common practice.

Here are the results (also sent as attachments):

Klaus,



Thanks for the info.  I did try the following:



Added a new user:  adduser kea -s /sbin/nologin 
Created the file:   /etc/systemd/system/kea.service




[Unit]
Description=kea Service
After=network.target

[Service]
Type=simple
User=kea
ExecStart=/usr/local/sbin/keactrl start
Restart=on-abort


[Install]
WantedBy=multi-user.target





Then I type this command: systemctl start kea
Then I check it with this command:  systemctl status kea




[root@localhost todsimmo]# systemctl status kea
‚óè kea.service - kea Service
   Loaded: error (Reason: Invalid argument)
   Active: failed (Result: exit-code) since Wed 2016-07-20 14:01:45 CDT; 5min 
ago
 Main PID: 4111 (code=exited, status=1/FAILURE)







I’ve also tried calling the kea-dhcp4 command, but it doesn’t work either.



Any help is appreciated,









Todd

CentOS 7 uses systemd. I'm by no means an expert on it, but you may be able to 
shoehorn systemd into thinking that it's a managed service (there's apparently 
legacy support for SVR4-style init scripts) using systemctl. Again, being still 
new to systemd
myself, I can't really offer much useful advice beyond that, but that's where 
I'd start looking.
