2.5.1 Installing MySQL on Linux Using the MySQL Yum Repository

The MySQL Yum repository for Oracle Linux, Red Hat Enterprise Linux, CentOS, and Fedora provides RPM packages for installing the MySQL server, client, MySQL Workbench, MySQL Utilities, MySQL Router, MySQL Shell, Connector/ODBC, Connector/Python and so on (not all packages are available for all the distributions; see Installing Additional MySQL Products and Components with Yum for details).

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 MySQL is not already installed on your system using a third-party-distributed RPM package; if that is not the case, follow the instructions given in Section 2.10.7, “Upgrading MySQL with the MySQL Yum Repository” or 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:

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:

$> sudo yum install platform-and-version-specific-package-name.rpm 

$> sudo yum install mysql80-community-release-el6- .noarch.rpm 

$> sudo yum install mysql80-community-release-el7- .noarch.rpm 

$> sudo yum install mysql80-community-release-el8- .noarch.rpm 

$> sudo yum install mysql80-community-release-el9- .noarch.rpm 

$> sudo dnf install mysql80-community-release-fc36- .noarch.rpm 

$> sudo dnf install mysql80-community-release-fc37- .noarch.rpm 

$> sudo dnf install mysql80-community-release-fc38- .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 (for dnf-enabled systems, replace yum in the command with dnf ):

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

Once the MySQL Yum repository is enabled on your system, any system-wide update by the yum update command (or dnf upgrade for dnf-enabled systems) upgrades MySQL packages on your system and replaces any native third-party packages, if Yum finds replacements for them in the MySQL Yum repository; see Section 2.10.7, “Upgrading MySQL with the MySQL Yum Repository”, for a discussion on some possible effects of that on your system, see Upgrading the Shared Client Libraries.

Selecting a Release Series

When using the MySQL Yum repository, the latest GA series (currently MySQL 8.0) 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 8.0) is enabled by default, and the subrepositories for all other series (for example, the MySQL 8.0 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 (for dnf-enabled systems, replace yum in the command with dnf ):

$> 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 8.0 series:

$> sudo yum-config-manager --disable mysql57-community $> sudo yum-config-manager --enable mysql80-community 

$> sudo dnf config-manager --disable mysql57-community $> sudo dnf config-manager --enable mysql80-community 

Besides using yum-config-manager or the dnf 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-2022 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 8.0, make sure you have enabled=0 for the above subrepository entry for MySQL 5.7, and have enabled=1 for the entry for the 8.0 series:

# Enable to use MySQL 8.0 [mysql80-community] name=MySQL 8.0 Community Server baseurl=http://repo.mysql.com/yum/mysql-8.0-community/el/6/$basearch/ enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql-2022 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, Yum uses the latest series. Verify that the correct subrepositories have been enabled and disabled by running the following command and checking its output (for dnf-enabled systems, replace yum in the command with dnf ):

$> yum repolist enabled | grep mysql 

Disabling the Default MySQL Module

(EL8 systems only) EL8-based systems such as RHEL8 and Oracle Linux 8 include a MySQL module that is enabled by default. Unless this module is disabled, it masks packages provided by MySQL repositories. To disable the included module and make the MySQL repository packages visible, use the following command (for dnf-enabled systems, replace yum in the command with dnf ):

$> sudo yum module disable mysql 

Installing MySQL

Install MySQL by the following command (for dnf-enabled systems, replace yum in the command with dnf ):

$> sudo yum install mysql-community-server 

Starting the MySQL Server

$> systemctl start mysqld 

$> systemctl status mysqld 

If the operating system is systemd enabled, standard systemctl (or alternatively, service with the arguments reversed) commands such as stop , start , status , and restart should be used to manage the MySQL server service. The mysqld service is enabled by default, and it starts at system reboot. See Section 2.5.9, “Managing MySQL Server with systemd” for additional information.

At the initial start up of the server, the following happens, given that the data directory of the server is empty:

• The server is initialized.
• SSL certificate and key files are generated in the data directory.
• validate_password is installed and enabled.
• A superuser account ‘root’@’localhost is created. A password for the superuser is set and stored in the error log file. To reveal it, use the following command:

$> sudo grep 'temporary password' /var/log/mysqld.log 

Change the root password as soon as possible by logging in with the generated, temporary password and set a custom password for the superuser account:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!'; 

validate_password is installed by default. The default password policy implemented by validate_password requires that passwords contain at least one uppercase letter, one lowercase letter, one digit, and one special character, and that the total password length is at least 8 characters.

For more information on the postinstallation procedures, see Section 2.9, “Postinstallation Setup and Testing”.

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 cannot install these packages (and vice versa).

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 (for dnf-enabled systems, replace yum in the command with dnf ):

$> 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 (for dnf-enabled systems, replace yum in the command with dnf ):

$> sudo yum install package-name 

For example, to install MySQL Workbench on Fedora:

$> sudo dnf install mysql-workbench-community 

To install the shared client libraries (for dnf-enabled systems, replace yum in the command with dnf ):

$> sudo yum install mysql-community-libs 

Platform Specific Notes

ARM 64-bit (aarch64) is supported on Oracle Linux 7 and requires the Oracle Linux 7 Software Collections Repository (ol7_software_collections). For example, to install the server:

$> yum-config-manager --enable ol7_software_collections $> yum install mysql-community-server

ARM 64-bit (aarch64) is supported on Oracle Linux 7 as of MySQL 8.0.12.

The 8.0.12 release requires you to adjust the libstdc++7 path by executing ln -s /opt/oracle/oracle-armtoolset-1/root/usr/lib64 /usr/lib64/gcc7 after executing the yum install step.

Updating MySQL with Yum

Besides installation, you can also perform updates for MySQL products and components using the MySQL Yum repository. See Section 2.10.7, “Upgrading MySQL with the MySQL Yum Repository” for details.

2.5 Installing MySQL on Linux

Linux supports a number of different solutions for installing MySQL. We recommend that you use one of the distributions from Oracle, for which several methods for installation are available:

Table 2.8 Linux Installation Methods and Information

Type	Setup Method	Additional Information
Apt	Enable the MySQL Apt repository	Documentation
Yum	Enable the MySQL Yum repository	Documentation
Zypper	Enable the MySQL SLES repository	Documentation
RPM	Download a specific package	Documentation
DEB	Download a specific package	Documentation
Generic	Download a generic package	Documentation
Source	Compile from source	Documentation
Docker	Use the Oracle Container Registry. You can also use Docker Hub for MySQL Community Edition and My Oracle Support for MySQL Enterprise Edition.	Documentation
Oracle Unbreakable Linux Network	Use ULN channels	Documentation

As an alternative, you can use the package manager on your system to automatically download and install MySQL with packages from the native software repositories of your Linux distribution. These native packages are often several versions behind the currently available release. You are also normally unable to install development milestone releases (DMRs), since these are not usually made available in the native repositories. For more information on using the native package installers, see Section 2.5.7, “Installing MySQL on Linux from the Native Software Repositories”.

For many Linux installations, you want to set up MySQL to be started automatically when your machine starts. Many of the native package installations perform this operation for you, but for source, binary and RPM solutions you may need to set this up separately. The required script, mysql.server , can be found in the support-files directory under the MySQL installation directory or in a MySQL source tree. You can install it as /etc/init.d/mysql for automatic MySQL startup and shutdown. See Section 4.3.3, “mysql.server — MySQL Server Startup Script”.
