On debian based systems /etc/default/icinga2 is not read/used #6255

dupondje · 2018-04-24T14:47:41Z

Hi,

When installing icinga2 on a debian system, it should read /etc/default/icinga2 for some vars as stated in the docs.
But it seems like this is completely broken.

For example I added the following in the file:
ICINGA2_RLIMIT_STACK=524288

but its never used.

Also when you start icinga2, you get the following warning:
icinga2 variable get RLimitStack
[2018-04-24 16:34:45 +0200] warning/icinga-app: Sysconfig file '/etc/sysconfig/icinga2' cannot be read. Using default values.
262144

Seems to be a cmake bug?
When just running cmake . on v2.8.3, the variable is filled incorrectly:
//where to store configuation for the init system, defaults to
// /etc/sysconfig/icinga2
ICINGA2_SYSCONFIGFILE:PATH=/usr/local/etc/sysconfig/icinga2

Which version are you using exactly? Please always fill in the issue templates.

dupondje · 2018-04-24T15:32:07Z

I'm using 2.8.3

dnsmichi · 2018-04-24T15:36:06Z

Please show us the output of icinga2 --version.

Just faced the same issue on Debian 9 and Ubuntu 17.10.

Seems that Icinga is looking for /etc/sysconfig/icinga2 but on Debian/Ubuntu this file is located in /etc/defaults/icinga2.

Try the following workaround until 2.9 is released:

mkdir -p /etc/sysconfig
ln -s /usr/lib/icinga2/icinga2 /etc/sysconfig/icinga2

lazyfrosch · 2018-04-25T08:05:51Z

Oh damn, we really need to fix this, and better move the environment read to the icinga2 wrapper script...

Daemons are not really supposed to include something from default/sysconfig

dnsmichi · 2018-05-02T09:05:56Z

Scheduled for CW21.

dnsmichi · 2018-05-22T12:20:24Z

Change icinga-app to read environment variables (drop our own reading from file)
Move default variables into prepare-dirs / safe-reload
Provide commented out values for sysconfig
Adopt Debian/RPM packages for the default paths

The sysconfig file now only contains the defaults as comments, changes made there are given to the init.d script, prepare-dirs, safe-reload and Icinga 2 itself. If nothing is set in the sysconfig file (as is the default as all lines are commented out) the defaults are used. fixes #6255

mcktr · 2018-06-18T16:12:07Z

I tested the latest snapshot package and faced the same issue.

Is the fix already available through snapshot packages or is there more work to do e.g. on the build scripts?

dnsmichi · 2018-06-18T17:04:15Z

The warning shouldn't be there, thanks for testing.

I've tested this on Ubuntu 16.04, but the only thing that worked for me was changing the user and group Icinga runs as.

For the *_DIR options, the directories where created but never used.

Working:

ICINGA2_USER=root
ICINGA2_GROUP=icingaweb2

Not working:

DAEMON=/usr/sbin/icinga2asdg
ICINGA2_CONFIG_FILE=/etc/icinga2/icinga7.conf
ICINGA2_RUN_DIR=/run/icinga7
ICINGA2_STATE_DIR=/var/icinga7
ICINGA2_PID_FILE=/run/icinga2/icinga7.pid
ICINGA2_LOG_DIR=/var/log/icinga7
ICINGA2_ERROR_LOG=/var/log/icinga2/error_dasd.log
ICINGA2_STARTUP_LOG=/var/log/icinga2/startup_Dasda.log

Paths are likely handled differently by the Debian/Ubuntu scripts, they're separated from upstream. Anyhow, path changes are not officially supported, my main concern was the environment variables read from the daemon, thus being the user and the rlimit configuration. Thanks for testing 👍
