MySQL :: Using the MySQL Yum Repository :: 1 Installing MySQL on Linux Using the MySQL Yum Repository

  1. Adding the MySQL Yum Repository

    First, add the MySQL Yum repository to your system's repository list. This is a one-time operation, which can be performed by installing an RPM provided by MySQL. Follow these steps:

    1. Go to the Download MySQL Yum Repository page (https://dev.mysql.com/downloads/repo/yum/) in the MySQL Developer Zone.

    2. Select and download the release package for your platform.

    3. Install the downloaded release package with the following command, replacing platform-and-version-specific-package-name with the name of the downloaded RPM package:

      shell> sudo yum localinstall platform-and-version-specific-package-name.rpm

      For an EL6-based system, the command is in the form of:

      shell> sudo yum localinstall mysql57-community-release-el6-{version-number}.noarch.rpm

      For an EL7-based system:

      shell> sudo yum localinstall mysql57-community-release-el7-{version-number}.noarch.rpm

      The installation command adds the MySQL Yum repository to your system's repository list and downloads the GnuPG key to check the integrity of the software packages. See Signature Checking Using GnuPG for details on GnuPG key checking.

      You can check that the MySQL Yum repository has been successfully added by the following command:

      shell> yum repolist enabled | grep "mysql.*-community.*"

    Note

    Once the MySQL Yum repository is enabled on your system, any system-wide update by the yum update command will upgrade MySQL packages on your system and also replace any native third-party packages, if Yum finds replacements for them in the MySQL Yum repository; see Chapter 3, Upgrading MySQL with the MySQL Yum Repository and, for a discussion on some possible effects of that on your system, see Upgrading the Shared Client Libraries.

  2. Selecting a Release Series

    When using the MySQL Yum repository, the latest GA series (currently MySQL 5.7) is selected for installation by default. If this is what you want, you can skip to the next step, Installing MySQL.

    Within the MySQL Yum repository, different release series of the MySQL Community Server are hosted in different subrepositories. The subrepository for the latest GA series (currently MySQL 5.7) is enabled by default, and the subrepositories for all other series (for example, the MySQL 5.6 series) are disabled by default. Use this command to see all the subrepositories in the MySQL Yum repository, and see which of them are enabled or disabled:

    shell> yum repolist all | grep mysql

    To install the latest release from the latest GA series, no configuration is needed. To install the latest release from a specific series other than the latest GA series, disable the subrepository for the latest GA series and enable the subrepository for the specific series before running the installation command. If your platform supports yum-config-manager, you can do that by issuing these commands, which disable the subrepository for the 5.7 series and enable the one for the 5.6 series:

    shell> sudo yum-config-manager --disable mysql57-community
    shell> sudo yum-config-manager --enable mysql56-community

    Besides using yum-config-manager command, you can also select a release series by editing manually the /etc/yum.repos.d/mysql-community.repo file. This is a typical entry for a release series' subrepository in the file:

    [mysql57-community]
    name=MySQL 5.7 Community Server
    baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/6/$basearch/
    enabled=1
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

    Find the entry for the subrepository you want to configure, and edit the enabled option. Specify enabled=0 to disable a subrepository, or enabled=1 to enable a subrepository. For example, to install MySQL 5.6, make sure you have enabled=0 for the above subrepository entry for MySQL 5.7, and have enabled=1 for the entry for the 5.6 series:

    # Enable to use MySQL 5.6
    [mysql56-community]
    name=MySQL 5.6 Community Server
    baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/
    enabled=1
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

    You should only enable subrepository for one release series at any time. When subrepositories for more than one release series are enabled, the latest series will be used by Yum.

    Verify that the correct subrepositories have been enabled and disabled by running the following command and checking its output:

    shell> yum repolist enabled | grep mysql

  3. Installing MySQL

    Install MySQL by the following command:

    shell> sudo yum install mysql-community-server

    This installs the package for MySQL server (mysql-community-server) and also packages for the components required to run the server, including packages for the client (mysql-community-client), the common error messages and character sets for client and server (mysql-community-common), and the shared client libraries (mysql-community-libs).

  4. Starting the MySQL Server

    Start the MySQL server with the following command:

    shell> sudo service mysqld start

    This is a sample output of the above command:

    Starting mysqld:[ OK ]

    You can check the status of the MySQL server with the following command:

    shell> sudo service mysqld status

    This is a sample output of the above command:

    mysqld (pid 3066) is running.

  5. Securing the MySQL Installation

    The program mysql_secure_installation allows you to perform important operations like setting the root password, removing anonymous users, and so on. Always run it to secure your MySQL installation:

    shell> mysql_secure_installation

    It is important to remember the root password you set. See mysql_secure_installation — Improve MySQL Installation Security for details.
