Upgrading MySQL on Linux

You can upgrade to a newer version of MySQL on the Linux server on which Unified Manager is installed to obtain fixes for security vulnerabilities.

Before you begin

You must have root privileges for the Linux system on which Unified Manager is installed.

About this task

You can only upgrade to minor updates of MySQL 5.7, for example, 5.7.1 to 5.7.2 . You cannot upgrade to major versions of MySQL, for example, version 5.8.

Steps

  1. Log in as a root user on the Unified Manager host machine.
  2. Download the latest MySQL Community Server .rpm bundle on the target system.
  3. Untar the bundle to a directory on the target system.
  4. You will get multiple .rpm packages in the directory after untarring the bundle, but Unified Manager only needs the following rpm packages:
    • mysql-community-client-5.7.x
    • mysql-community-libs-5.7.x
    • mysql-community-server-5.7.x
    • mysql-community-common-5.7.x
    • mysql-community-libs-compat-5.7.x
    Delete all other .rpm packages. Installing all packages in an rpm bundle will not cause any problems.
  5. Stop the Unified Manager service and the associated MySQL software in the order shown: service ocieau stopservice ocie stopservice mysqld stop
  6. Invoke the upgrade of MySQL by using the following command: yum install *.rpm
    *.rpm refers to the .rpm packages in the directory where you downloaded the newer version of MySQL.
  7. Start Unified Manager in the order shown: service mysqld startservice ocie startservice ocieau start
