Bug 485442 – dev-db/mongodb: add systemd unit file

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Peter Volkov (RETIRED) 2013-09-19 19:34:39 UTC]

Created attachment 359052 [details]
mongodb@.service

Attached is a template unit file. To start mongod you'll need to create custom configuration file in /etc/monogdb/. I suggest to use

https://projects.archlinux.org/svntogit/community.git/plain/trunk/mongodb.conf?h=packages/mongodb

as a "default" configuration (/etc/mongodb/mongodb.conf. I decided to opt-out most command line options we currently use in init.d and put them in config file.

Please, add it to the tree.

Why do you want to only provide a template unit instead of a normal one? I only see normal ones in other distributions
https://projects.archlinux.org/svntogit/community.git/tree/trunk/mongodb.service?h=packages/mongodb
(for example)

Well, this is just personal convenience as I wanted multiple mongodb instances running in parallel. But I think this is mostly development configuration. So I don't see a big problem if we'll have normal unit file, like in archlinux. That said, note, that we'll need /etc/mongodb.conf file then.

Personally, I would opt for the normal naming (it's also used in opensuse, fedora and mageia) :/

[Comment 4 Michał Górny 2013-09-25 22:58:15 UTC]

Inventing new config file locations and confusing @ units for personal convenience is something you should do locally. Users aren't really supposed to guess what should go after the '@', and where they should place the config file afterwards.

Just provide a simple 'mongodb.service' with proper config-file location. If someone needs multiple instances, systemd makes inheriting and extending services easy enough.

/etc/<servicename>/ is a standard location in Gentoo.

How the are supposed to know this for other cases:

autovt@.service             mongodb@.service       sshd@.service            wpa_supplicant@.service
configure-printer@.service  openvpn@.service       systemd-fsck@.service
getty@.service              serial-getty@.service  systemd-nspawn@.service
hplip-printer@.service      smbd@.service          user@.service

?

That said, I already agreed that normal naming is Ok for now.

Was trying to use:
https://projects.archlinux.org/svntogit/community.git/plain/trunk/mongodb.service?h=packages/mongodb

but this requires old v8 version (that blocks chromium) :@
