Installing mongoDB in CentOS and Connecting to mongoDB from PHP

There are 2 parts to this article:

1. Installing mongoDB Server

2. Installing PHP mongo extension and make it work!

Part 1: Installing mongoDB Server on CentOS 6.3

Create mongoDB repository configuration:

[bash]

cd /etc/yum/repos.d

vi /etc/yum.repos.d/10gen.repo

[/bash]

Write the following script to create the mongoDB repository configuration:

[bash][10gen]
name=10gen Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64
gpgcheck=0
enabled=1[/bash]

Save the configuration file and install mongoDB:

[bash]yum install mongo-10gen mongo-10gen-server[/bash]

The configuration file is residing on /etc/mongod.conf, and the start/stop/restart script is /etc/rc.d/init.d/mongod. To start the service:

[bash]/etc/init.d/mongod restart[/bash]

Make sure the daemon works properly:

[bash]chkconfig mongod on[/bash]

It is running now. This MongoDB instance will store its data files in the /var/lib/mongo and its log files in /var/log/mongo, and run using the mongod user account.

Next step we are going to install PHP mongo extension.
