icingadb initscript for non-systemd OS

[wwuck]

I have an icinga2 instance with icingaweb2 and monitoring module running on Devuan 4 (Debian 11 derivative without systemd) working successfully. I am attempting to install icingadb using the instructions at https://icinga.com/docs/icinga-db/latest/doc/02-Installation/03-Debian/ but the icingadb package only provides a systemd service file. I am using the icinga APT repository for all icinga related packages.

Can you please add a initscript /etc/init.d/icingadb for non-sytemd users? I can see that icingadb-redis-server already provides an initscript.

I have tested the following changes manually on my instance and it appears to be working ok. I'm not sure if there are better ways to be doing some of these, eg. log file.

Also mkdir -p /var/log/icingadb and chown icingadb:adm /var/log/icingadb.

After consideration we've decided against adding an initscript to IcingaDB - we don't officially support any Linux distributions without systemd, and we don't have the capacity to properly maintain and test and give support for initscripts over a wide range of systems and Icinga modules.

Other initscripts in Icinga projects are there for legacy reasons; icingadb-redis-server does have one because its source provides one. We'd suggest using systemd with Icinga - you're obviously free to use your initscript in any way you'd want, but we can't provide support for it.

Thanks for the information @htriem. I did look through all the website, docs, GitHub, etc. everywhere previously and I didn’t see it written anywhere that icinga has a requirement on systemd and that non-systemd is unsupported. Can you please point me to where I can find that?

non-systemd init systems (sysvinit, runit, openrc, s6, etc.) are still a supported configuration in Debian.
