How to install mongoDB on Ubuntu

This guide shows you how to install MongoDB on Ubuntu.

Ubuntu 12.10
MongoDB 2.2.3

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?

MongoDB is installed and started.

$ ps -ef | grep mongo
mongodb   5262     1  0 15:27 ?        00:00:14 /usr/bin/mongod --config /etc/mongodb.conf
mkyong    5578  3994  0 16:29 pts/0    00:00:00 grep --color=auto mongo
 
$ mongo -version
MongoDB shell version: 2.2.3

All MongoDB executable files are stored at /usr/bin/

$ ls -ls /usr/bin | grep mongo
 4220 -rwxr-xr-x 1 root   root     4317928 Feb  2 08:11 mongo
10316 -rwxr-xr-x 1 root   root    10563336 Feb  2 08:11 mongod
10320 -rwxr-xr-x 1 root   root    10563664 Feb  2 08:11 mongodump
10284 -rwxr-xr-x 1 root   root    10526736 Feb  2 08:11 mongoexport

10296 -rwxr-xr-x 1 root   root    10539056 Feb  2 08:11 mongoimport
10272 -rwxr-xr-x 1 root   root    10514544 Feb  2 08:11 mongooplog
10272 -rwxr-xr-x 1 root   root    10518512 Feb  2 08:11 mongoperf
10320 -rwxr-xr-x 1 root   root    10563632 Feb  2 08:11 mongorestore
 6644 -rwxr-xr-x 1 root   root     6802848 Feb  2 08:11 mongos
10312 -rwxr-xr-x 1 root   root    10556560 Feb  2 08:11 mongostat
10272 -rwxr-xr-x 1 root   root    10515856 Feb  2 08:11 mongotop

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.

#where to log
