Install MongoDB and the PHP driver in CentOS

Install MongoDB server

Create the /etc/yum.repos.d/mongodb-org-3.0.repo file with this content:

[mongodb-org-3.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.0/x86_64/
gpgcheck=0
enabled=1

Then install mongodb with this commando:

# yum install -y mongodb-org

This are the important files and folders for MongoDB in CentOS:

• Configuration file: /etc/mongod.conf
• Data files: /var/lib/mongo/
• Logs files: /var/log/mongodb/

By default the used port is 27017 and also you can ONLY make connections to it within the localhost or 127.0.0.1. If you want to change that you have to edit the bind_ip option:

bind_ip=127.0.0.1

To start the server run this command:

# service mongod start

To stop the server run this command:

# service mongod stop

If you want the server to start on boot:

# chkconfig mongod on

Once the service is running we can connect to it with the mongo command:

$ mongo
MongoDB shell version: 3.0.6
connecting to: test

Install the PHP driver

Install the required dependencies and the mongo PHP driver itself:

# yum -y install gcc openssl-devel php-devel php-cli php-pear
# pecl install mongo

Note: the library will be installed in /usr/lib64/php/modules/mongo.so

Activate it in /etc/php.ini or in it's own file in /etc/php.d/30-mongo.ini:

extension=mongo.so

And finally restart httpd:

# service httpd restart
