MongoDB server won't start

Question

I just installed Arch Linux today. I'm setting up my development stack, and I'm stuck with mongodb.

I have followed this wiki when installing: https://wiki.archlinux.org/index.php/MongoDB#Installing_MongoDB

When I try to get into mongo console, I get this:

jan@arch:~$ mongo
MongoDB shell version: 2.4.5
connecting to: test
Tue Jul  9 19:38:13.365 JavaScript execution failed: Error: couldn't connect to server 127.0.0.1:27017 at src/mongo/shell/mongo.js:L112
exception: connect failed
jan@arch:~$

What am I missing here?

EDIT: I figured out when I run mongod directly from terminal, it starts server fine. However the systemctl start mongodb doesn't start it.

Try executing the startup script manually. It might be pointed at the wrong path or something. — Chris Heald, Jul 09 '13 at 18:23

Okay, I've figured it out by scanning journalctl output:

ul 09 19:49:33 arch mongod[1122]: all output going to: /var/log/mongodb/mongod.log Jul 09 19:49:33 arch mongod[1122]: can't open [/var/log/mongodb/mongod.log] for log file: errno:13 Permission denied Jul 09 19:49:33 arch mongod[1122]: Bad logpath value: "/var/log/mongodb/mongod.log"; terminating.

So I searched for user that might be utilized by mongodb:

jan@arch:~$ cat /etc/passwd
root:x:0:0:root:/root:/bin/bash
...
mongodb:x:998:2::/var/lib/mongodb:/bin/bash

And chowned required folders:

jan@arch:~$ sudo chown -R mongodb:x /var/log/mongodb/
jan@arch:~$ sudo chown -R mongodb:x /var/lib/mongodb/

Started it again:

jan@arch:~$ sudo systemctl start mongodb

It works now.

 jan@arch:~$ mongo
    MongoDB shell version: 2.4.5
    connecting to: test
