Enabling SELinux

You can enable SELinux and set it to enforcing in an existing Oracle Communications Unified Assurance environment where it was previously disabled.

Note:

This is supported for existing Unified Assurance version 6.0.5 environments.

To enable SELinux on an existing Unified Assurance environment, do the following on all servers:

  1. Perform the prerequisite steps in Configuring SELinux in Unified Assurance Installation Guide.

  2. Confirm that you have installed the correct versions of the required packages listed in Installing Required Package Dependencies. This task was likely performed when you installed or updated to Unified Assurance 6.0.5.

  3. Open the /etc/selinux/config file.

    Note:

    This is the core Linux etc directory, not the Unified Assurance $A1BASEDIR/etc directory.

  4. Change the SELINUX= line to SELINUX=enforcing.

  5. Save and close the file.

  6. Reboot the server.

  7. Run the ConfigSELinuxDocker application:

    $A1BASEDIR/bin/ConfigSELinuxDocker enable

    ConfigSELinuxDocker confirms that the required dependencies are met and sets up SELinux for the Unified Assurance instance of Docker.
