NoSQL database for Red Hat Enterprise Linux and CentOS¶

Install and configure components¶

1. Install the MongoDB packages:

   # yum install mongodb-server mongodb
   

2. Edit the /etc/mongod.conf file and complete the following actions:

   • Configure the bind_ip key to use the management interface IP address of the controller node.

     bind_ip = 10.0.0.11
     

   • By default, MongoDB creates several 1 GB journal files in the /var/lib/mongodb/journal directory. If you want to reduce the size of each journal file to 128 MB and limit total journal space consumption to 512 MB, assert the smallfiles key:

     smallfiles = true
     

     You can also disable journaling. For more information, see the MongoDB manual.

Finalize installation¶

• Start the MongoDB service and configure it to start when the system boots:

  # systemctl enable mongod.service
  # systemctl start mongod.service
