MongoDB Installation

1. Add 10gen package to source.list.d
Ubuntu 12 comes with a “mongo” package, but not the latest version.
   
    $ sudo apt-cache search mongodb
        mongodb
        mongodb-clients
        mongodb-dev
        mongodb-server

It’s recommended to add 10gen package to /etc/apt/sources.list.d, as it contains the latest stable MongoDB. Create a /etc/apt/sources.list.d/mongo.list file, and declared the 10gen distro.

         $ sudo vim /etc/apt/sources.list.d/mongo.list
            /etc/apt/sources.list.d/mongo.list
            ##10gen package location

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

2. Add GPG Key

10gen package required GPG key, imports it :

$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10

If you didn’t imports the GPG key, apt-get update will hits following error message :

GPG error: http://downloads-distro.mongodb.org dist Release:

The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9ECBEC467F0CEB10

3. Update package
Update your apt-get list.

       $ sudo apt-get update

Search “mongodb” again, a new 10gen package is appearing now. Get the “mongodb-10gen“, it contains the latest stable MongoDB.

       $ sudo apt-cache search mongodb
          mongodb
          mongodb-clients
          mongodb-dev
          mongodb-server

          mongodb-10gen
          mongodb18-10gen
          mongodb20-10gen

4. Install mongodb-10gen
Everything is ready, now you can Install MongoDB :

    $ sudo apt-get install mongodb-10gen

5. Where is MongoDB?

The “mongodb control script” is generated at /etc/init.d/mongodb

$ ls -ls /etc/init.d | grep mongo
0 lrwxrwxrwx 1 root root   21 Feb  2 08:11 mongodb -> /lib/init/upstart-job
The MongoDB config file is at /etc/mongodb.conf
/etc/mongodb.conf
# mongodb.conf
# Where to store the data.
# Note: if you run mongodb as a non-root user (recommended) you may
# need to create and set permissions for this directory manually,
# e.g., if the parent directory isn't mutable by the mongodb user.

dbpath=/var/lib/mongodb
#where to log
logpath=/var/log/mongodb/mongodb.log
logappend=true
#port = 27017
