The MySQL Yum repository provides RPM packages for installing the MySQL server, client, and other components on Linux platforms. The packages also upgrade and replace any third-party MySQL packages installed from the Linux distros' native software repositories, if replacements for them are available from MySQL.
The MySQL Yum repository supports the following Linux platforms :
EL5-, EL6-, and EL7-based platforms (for example, the corresponding versions of Red Hat Enterprise Linux, Oracle Linux, and CentOS)
Fedora 23 and 24
This is a quick guide to using the MySQL Yum repository. For more information, see Further Readings.

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 Replacing a Native Third-Party Distribution of MySQL.
First, add the MySQL Yum repository to your system's repository list. Follow these steps:
Go to the download page for MySQL Yum repository at http://dev.mysql.com/downloads/repo/yum/.
Select and download the release package for your platform.
Install the downloaded release package with the following command, replacing
platform-and-version-specific-package-namewith the name of the downloaded package:
sudo rpm -Uvh
For example, for version
nof the package for EL6-based systems, the command is:
sudo rpm -Uvh mysql57-community-release-el6-
Once the release package is installed on your system, any system-wide update by the yum update command (or dnf upgrade for dnf-enabled systems) will automatically 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 Upgrading MySQL with the MySQL Yum Repository and Replacing a Native Third-Party Distribution of MySQL for details.
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 (http://repo.mysql.com/yum/), 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 (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. You can do that by editing manually the
/etc/yum.repos.d/mysql-community.repofile. 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/$basearch/ enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
Find the entry for the subrepository you want to configure, and edit the
enabled=0to disable a subrepository, or
enabled=1to enable a subrepository. For example, to install MySQl 5.6, make sure you have
enabled=0for the above subrepository entry for MySQL 5.7, and have
enabled=1for the entry for the 5.6 series:
# Enable to use MySQL 5.6 [mysql56-community] name=MySQL 5.6 Community Server baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$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 (for dnf-enabled systems, replace yum in the command with dnf):
yum repolist enabled | grep mysql
Install MySQL by the following command (for dnf-enabled systems, replace yum in the command with dnf):
sudo yum install mysql-community-server
This installs the package for the MySQL server, as well as other required packages.
Start the MySQL server with the following command:
sudo service mysqld start
You can check the status of the MySQL server with the following command:
sudo service mysqld status
For MySQL 5.7 only: 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.
An SSL certificate and key files are generated in the data directory.
The validate_password plugin 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 -uroot -p
ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';
MySQL's validate_password plugin is installed by default. This will require that passwords contain at least one upper case letter, one lower case letter, one digit, and one special character, and that the total password length is at least 8 characters.
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 5.6 installation:
It is important to remember the root password you set. See mysql_secure_installation — Improve MySQL Installation Security for details.
Do not run mysql_secure_installation after an installation of MySQL 5.7, as the function of the programe has already been performed by the Yum repository installation.
For EL7-based platforms: See Compatibility Information for EL7-based platforms.
You can use Yum to install and manage individual components of MySQL. Some of these components are hosted in subrepositories of the MySQL Yum repository. Use the following command to list the packages for all the MySQL components available for your platform from all subrepositories in the MySQL Yum repository (for dnf-enabled systems, replace yum in the command with dnf):
yum --disablerepo=\* --enablerepo='mysql*-community*' list available
Install any packages of your choice with the following command,
package-name with name of the
package (for dnf-enabled systems, replace yum
in the command with dnf):
sudo yum install
For example, to install MySQL Workbench on Fedora 24:
sudo dnf install mysql-workbench-community
Before performing any update to MySQL, follow carefully the instructions in Upgrading MySQL. Among other instructions discussed there, it is especially important to back up your database before the update.
Use the MySQL Yum repository to perform an in-place update (that is, replacing the old version and then running the new version off the old data files) for your MySQL installation by following these steps (they assume you have installed MySQL with the MySQL Yum repository or with an RPM package directly downloaded from MySQL Developer Zone's MySQL Download page; if that is not the case, following the instructions in Replacing a Native Third-Party Distribution of MySQL instead):
By default, the MySQL Yum repository updates MySQL to the latest version in the release series you have chosen during installation (see Selecting a Release Series for details), which means, for example, a 5.6.x installation will NOT be updated to a 5.7.x release automatically. To update to another release series, you need to first disable the subrepository for the series that has been selected (by default, or by yourself) and enable the subrepository for your target series. To do that, see the general instructions given in Selecting a Release Series for editing the subrepository entries in the
/etc/yum.repos.d/mysql-community.repofile. For upgrading from MySQL 5.6 to 5.7, perform the reverse of the steps illustrated in Selecting a Release Series, disabling the subrepository for the MySQL 5.6 series and enabling that for the MySQL 5.7 series.
As a general rule, to upgrade from one release series to another, go to the next series rather than skipping a series. For example, if you are currently running MySQL 5.5 and wish to upgrade to 5.7, upgrade to MySQL 5.6 first before upgrading to 5.7.Important
For important information about upgrading from MySQL 5.5 to 5.6, see Upgrading from MySQL 5.5 to 5.6.
For important information about upgrading from MySQL 5.6 to 5.7, see Upgrading from MySQL 5.6 to 5.7.
For important information about upgrading from MySQL 5.7 to 8.0, see Upgrading from MySQL 5.7 to 8.0.
In-place downgrading of MySQL is not supported by the MySQL Yum repository. Follow the instructions in Downgrading MySQL.
Upgrade MySQL and its components by the following command, for platforms that are not dnf-enabled:
sudo yum update mysql-server
For dnf-enabled systems:
sudo dnf --refresh upgrade mysql-server
Alternatively, you can update MySQL by telling Yum to update everything on your system, which might take considerably more time; for platforms that are not dnf-enabled:
sudo yum update
For dnf-enabled systems:
sudo dnf upgrade
The MySQL server always restarts after an update by Yum. Once the server restarts, run mysql_upgrade to check and possibly resolve any incompatibilities between the old data and the upgraded software. mysql_upgrade also performs other functions; see mysql_upgrade — Check and Upgrade MySQL Tables for details.
You can also update only a specific component. Use the following command to list all the installed packages for the MySQL components (for dnf-enabled systems, replace yum in the command with dnf):
sudo yum list installed | grep "^mysql"
After identifying the package name of the component of your
choice, for platforms that are not dnf-enabled, update the package
with the following command, replacing
package-name with the name of the
sudo yum update
For dnf-enabled systems:
sudo dnf upgrade
To replace third-party distributions of MySQL that were installed from the supported Linux platforms' native software repositories with the latest GA release (from the MySQL 5.7 series currently) from the MySQL Yum repository, follow these steps:
To avoid loss of data, always back up your database before trying to replace your MySQL installation using the MySQL Yum repository. See Backup and Recovery on how to back up your database.
Add the MySQL Yum repository to your system's repository list by following the instructions given in Adding the MySQL Yum Repository.
By design, the MySQL Yum repository will replace your native, third-party MySQL with the latest GA release (from the MySQL 5.7 series currently) from the MySQL Yum repository when you perform a yum update command (or dnf upgrade for dnf-enabled systems) on the system, or a yum update mysql-server (or dnf upgrade mysql-server for dnf-enabled systems).
After updating MySQL using the Yum repository, applications compiled with older versions of the shared client libraries should continue to work. However, if you want to recompile applications and dynamically link them with the updated libraries, see Upgrading the Shared Client Libraries for some special considerations.
For EL7-based platforms: See Compatibility Information for EL7-based platforms.
If you have a third-party distribution of MySQL that you have downloaded and installed from a nonnative repository (for example, from MariaDB or Percona), it is important to follow the instructions for replacing them given in the MySQL server's reference manual.
