How to start MongoDB server on system start?

Question

I have to start my MongoDB server every time the system restarts. How do I configure it to start with my OS? I am on Ubuntu 11.04.

Answer 1

If you install MongoDB using the Advanced Packaging Tool (apt) then it'll configure your startup scripts to automatically run Mongo when the system boots.

The steps are as follows, first configure apt to be able to download the Mongo package:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10
sudo nano /etc/apt/sources.list

Add this line to sources.list then save:

deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen

Then download and install Mongo with the apt-get utility:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install mongodb-10gen

If you want to make any changes to config, edit your mongodb.conf and restart:

sudo nano /etc/mongodb.conf
sudo service mongodb restart

Answer 2

Controlling all the init.d service links should be done with the update-rc.d tool

i.e. to turn on the mongod daemon in the default runlevels (i.e. turn it on at boot):

update-rc.d mongodb defaults

See https://help.ubuntu.com/community/UbuntuBootupHowto for more information. This link tells you everything you want to know about how to set programs at boot.

Answer 3

chkconfig --levels 235 mongod on?

where mongodb is the name of your service

I have consistently used this post as a starting point to get a new sharding rig up and running. It includes a section on configuring upstart that I've also used.

Answer 5

If you install MongoDB with apt-get as described in the MongoDB Ubuntu installation guide, it will come with a basic startup script and config file. (use of a config file is highly recommended)

You can also take a look here for an old post that links to an init.d script.

In either case, the basic premise is that you're setting up a service and then configuring to start-stop with the computer. This is pretty common technique for servers, there are lots of tutorials around for doing exactly this.
