Running Percona Server for MongoDB

Warning

If you have SELinux security module installed, it will conflict with Percona Server for MongoDB. There are several options to deal with this:

  • Remove the SELinux packages. This is not recommended, because it may violate security.

  • Disable SELinux by setting SELINUX in /etc/selinux/config to disabled. This change takes effect after you reboot.

  • Run SELinux in permissive mode by setting SELINUX in /etc/selinux/config to permissive. This change takes effect after you reboot.

    You can also enforce permissive mode at runtime using the setenforce 0 command. However, this will not affect the configuration after a reboot.

Percona Server for MongoDB stores data files in /var/lib/mongodb/ by default. The configuration file is /etc/mongod.conf.

Starting the service

Percona Server for MongoDB is not started automatically after installation. Start it manually using the following command:

$ sudo systemctl start mongod
Confirming that service is running

Check the service status using the following command: systemctl status mongod

$ sudo systemctl status mongod
Stopping the service

Stop the service using the following command: systemctl stop mongod

$ sudo systemctl stop mongod
Restarting the service

Restart the service using the following command: systemctl restart mongod

$ sudo systemctl restart mongod

Running after reboot

The mongod service is not automatically started after you reboot the system.

For RHEL or CentOS versions 5 and 6, you can use the chkconfig utility to enable auto-start as follows:

$ sudo chkconfig --add mongod

For RHEL or CentOS version 7, you can use the systemctl utility:

$ sudo systemctl enable mongod

Uninstalling Percona Server for MongoDB

To completely uninstall Percona Server for MongoDB you’ll need to remove all the installed packages and data files:

Run the following commands as root or by using the sudo command

  1. Stop the Percona Server for MongoDB service:

    $ sudo systemctl stop mongod
    
  2. Remove the packages:

    $ sudo yum remove percona-server-mongodb*
    
  3. Remove the data and configuration files:

    $ sudo rm -rf /var/lib/mongodb
    $ sudo rm -f /etc/mongod.conf
    

Warning

This will remove all the packages and delete all the data files (databases, tables, logs, etc.). You might want to back up your data before doing this in case you need the data later.

Footnotes

[1]We support only the current stable RHEL 6 and CentOS 6 releases, because there is no official (i.e. RedHat provided) method to support or download the latest OpenSSL on RHEL and CentOS versions prior to 6.5. Similarly, and also as a result thereof, there is no official Percona way to support the latest Percona Server builds on RHEL and CentOS versions prior to 6.5. Additionally, many users will need to upgrade to OpenSSL 1.0.1g or later (due to the Heartbleed vulnerability), and this OpenSSL version is not available for download from any official RHEL and CentOS repositories for versions 6.4 and prior. For any officially unsupported system, src.rpm packages can be used to rebuild Percona Server for any environment. Please contact our support service if you require further information on this.
