2.5.1 Installing MySQL on Linux Using the MySQL Yum Repository

MySQL provides a Yum-style software repository for the following Linux platforms:

Currently, the MySQL Yum repository for the above-mentioned platforms provides RPM packages for installing the MySQL server, client, MySQL Workbench, MySQL Utilities (not available for EL5-based platforms), Connector/ODBC, and Connector/Python (not available for EL5-based platforms).

Before You Start

As a popular, open-source software, MySQL, in its original or re-packaged form, is widely installed on many systems from various sources, including different software download sites, software repositories, and so on. The following instructions assume that no versions of MySQL (whether distributed by Oracle or other parties) have already been installed on your system; if that is not the case, see Section 2.11.1.1, “Upgrading MySQL with the MySQL Yum Repository” or Section 2.5.2, “Replacing a Third-Party Distribution of MySQL Using the MySQL Yum Repository”.

Steps for a Fresh Installation of MySQL

Follow the steps below to install the latest GA version of MySQL with 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 (http://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 (except for EL5-based systems), 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 mysql-community-release-el6-{version-number}.noarch.rpm  
      

      For an EL7-based system:

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

      For Fedora 19:

      shell> sudo yum localinstall mysql-community-release-fc19-{version-number}.noarch.rpm
      

      For Fedora 20:

      shell> sudo yum localinstall mysql-community-release-fc20-{version-number}.noarch.rpm
      

      For an EL5-based system, use the following command instead:

      shell> sudo rpm -Uvh mysql-community-release-el5-{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 Section 2.1.4.2, “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 Section 2.11.1.1, “Upgrading MySQL with the MySQL Yum Repository” and, for a discussion on some possible effects of that on your system, see Upgrading to the Shared Client Libraries.

  2. Selecting a Release Series

    Note

    When using the MySQL Yum repository, the latest GA release of MySQL is selected for installation by default. If this is what you want, you can skip to the next step, Installing MySQL with Yum.

    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 5.6) is enabled by default, and the subrepositories for all other series (for example, the 5.7 series, currently still in developer milestone release (DMR) status) 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 5.6 series and enable the one for the 5.7 series:

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

    Besides using yum-config-manager, 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:

    # Enable to use MySQL 5.6
    [mysql56-community]
    name=MySQL 5.6 Community Server
    baseurl=//repo.mysql.com/yum/mysql-5.6-community/el/5/$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 the latest 5.7 DMR, make sure you have enabled=0 for the above subrepository entry for MySQL 5.6, and have enabled=1 for the entry for the 5.7 series:

    # Note: MySQL 5.7 is currently in development. For use at your own risk.
    # Please read with sub pages: https://dev.mysql.com/doc/relnotes/mysql/5.7/en/
    [mysql57-community-dmr]
    name=MySQL 5.7 Community Server Development Milestone Release
    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
    

    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 with Yum

    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 and Stopping 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.

    Stop the MySQL server with the following command:

    shell> sudo service mysqld stop

  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 Section 4.4.5, “mysql_secure_installation — Improve MySQL Installation Security” for details.

For more information on the postinstallation procedures, see Section 2.10, “Postinstallation Setup and Testing”.

Note

Compatibility Information for EL7-based platforms: The following RPM packages from the native software repositories of the platforms are incompatible with the package from the MySQL Yum repository that installs the MySQL server. Once you have installed MySQL using the MySQL Yum repository, you will not be able to install these packages (and vice versa).

  • akonadi-mysql

  • ocsinventory

Installing Additional MySQL Products and Components with Yum

You can use Yum to install and manage individual components of MySQL. Some of these components are hosted in sub-repositories of the MySQL Yum repository: for example, the MySQL Connectors are to be found in the MySQL Connectors Community sub-repository, and the MySQL Workbench in MySQL Tools Community. You can use the following command to list the packages for all the MySQL components available for your platform from the MySQL Yum repository:

shell> sudo yum --disablerepo=\* --enablerepo='mysql*-community*' list available

Install any packages of your choice with the following command, replacing package-name with name of the package:

shell> sudo yum install package-name 

For example, to install MySQL Workbench:

shell> sudo yum install mysql-workbench-community

To install the shared client libraries:

shell> sudo yum install mysql-community-libs

Updating MySQL with Yum

Besides installation, you can also perform updates for MySQL products and components using the MySQL Yum repository. See Section 2.11.1.1, “Upgrading MySQL with the MySQL Yum Repository” for details.
