MySQL :: A Quick Guide to Using the MySQL Yum Repository https://dev.mysql.com/doc/mysql-yum-repo-quick-guide/en/
Steps for a Fresh Installation of MySQL
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 inReplacing a Native Third-Party Distribution of MySQL.
-
Adding the MySQL Yum Repository
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:shell> sudo rpm -Uvh platform-and-version-specific-package-name.rpmFor example, for version
nof the package for EL6-based systems, the command is:shell> sudo rpm -Uvh mysql80-community-release-el6-n.noarch.rpm
NoteOnce the release package is installed on your system, any system-wide update by theyum 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. SeeUpgrading MySQL with the MySQL Yum Repository and Replacing a Native Third-Party Distribution of MySQL for details.

-
Selecting a Release Series
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 8.0) is enabled by default, and the subrepositories for all other series (for example, the MySQL 5.7 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):
shell> yum repolist all | grep mysqlTo 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 the yum-config-manager or dnf config-manager command, you can do that by issuing, for example, the following commands, which disable the subrepository for the 8.0 series and enable the one for the 5.7 series; for platforms that are not dnf-enabled:
shell> sudo yum-config-manager --disable mysql80-community shell> sudo yum-config-manager --enable mysql57-communityFor dnf-enabled platforms:
shell> sudo dnf config-manager --disable mysql80-community shell> sudo dnf config-manager --enable mysql57-communityBesides using yum-config-manager or the dnf config-manager command, you can also select a series by editing manually the
/etc/yum.repos.d/mysql-community.repofile. This is a typical entry for a release series' subrepository in the file:[mysql80-community] name=MySQL 8.0 Community Server baseurl=http://repo.mysql.com/yum/mysql-8.0-community/el/6/$basearch/ enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysqlFind the entry for the subrepository you want to configure, and edit the
enabledoption. Specifyenabled=0to disable a subrepository, orenabled=1to enable a subrepository. For example, to install MySQL 5.7, make sure you haveenabled=0for the above subrepository entry for MySQL 8.0, and haveenabled=1for the entry for the 5.7 series:# Enable to use MySQL 5.7 [mysql57-community] name=MySQL 5.7 Community Server baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/6/$basearch/ enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysqlYou 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):
shell> yum repolist enabled | grep mysql -
Installing MySQL
Install MySQL by the following command (for dnf-enabled systems, replace yum in the command with dnf):
shell> sudo yum install mysql-community-serverThis installs the package for the MySQL server, as well as other required packages.
-
Starting the MySQL Server
Start the MySQL server with the following command:
shell> sudo service mysqld startFor EL7-based platforms, this is the preferred command:
shell> sudo systemctl start mysqld.serviceYou can check the status of the MySQL server with the following command:
shell> sudo service mysqld statusFor EL7-based platforms, this is the preferred command:
shell> sudo systemctl status mysqld.serviceMySQL Server Initialization (as of MySQL 5.7): 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:shell> sudo grep 'temporary password' /var/log/mysqld.logChange the root password as soon as possible by logging in with the generated, temporary password and set a custom password for the superuser account:
shell> mysql -uroot -pmysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';
NoteMySQL'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.
-
-
Securing the MySQL Installation (for MySQL 5.6 only)
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:
shell> mysql_secure_installationIt 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 or higher, as the function of the program has already been performed by the Yum repository installation.
For EL7-based platforms: See Compatibility Information for EL7-based platforms.
Installing Additional MySQL Products and Components
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):
shell> yum --disablerepo=* --enablerepo='mysql*-community*' list availableInstall 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):
shell> sudo yum install package-nameFor example, to install MySQL Workbench on Fedora:
shell> sudo dnf install mysql-workbench-communityUpgrading MySQL with the MySQL Yum Repository
-
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):
-
Selecting a Target Series
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 5.7.x installation will NOT be updated to a 8.0.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 5.7 to 8.0, perform the reverse of the steps illustrated in Selecting a Release Series, disabling the subrepository for the MySQL 5.7 series and enabling that for the MySQL 8.0 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 5.6 and wish to upgrade to 8.0, upgrade to MySQL 5.7 first before upgrading to 8.0.
Important-
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.
-
-
Upgrading MySQL
Upgrade MySQL and its components by the following command, for platforms that are not dnf-enabled:
shell> sudo yum update mysql-serverFor dnf-enabled systems:
shell> sudo dnf --refresh upgrade mysql-serverAlternatively, 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:
shell> sudo yum updateFor dnf-enabled systems:
shell> sudo dnf upgrade -
Restarting MySQL
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):
shell> 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 package:
shell> sudo yum update package-nameFor dnf-enabled systems:
shell> sudo dnf upgrade package-nameReplacing a Native Third-Party Distribution of MySQL
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 8.0 series currently) from the MySQL Yum repository, follow these steps:
-
Backing Up Your Database
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.
-
Adding the MySQL Yum Repository
Add the MySQL Yum repository to your system's repository list by following the instructions given in Adding the MySQL Yum Repository.
-
Replacing the Native Third-Party Distribution by a Yum Update or a DNF Upgrade
By design, the MySQL Yum repository will replace your native, third-party MySQL with the latest GA release (from the MySQL 8.0 series currently) from the MySQL Yum repository when you perform a yum updatecommand (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.
Installing MySQL NDB Cluster Using the Yum Repository
-
The following instructions assume that neither the MySQL server nor MySQL NDB Cluster has already been installed on your system; if that is not the case, remove the MySQL server or MySQL NDB Cluster, including all its executables, libraries, configuration files, and data directories, before you continue. However there is no need to remove the release package you might have used to enable the MySQL Yum repository on your system.
-
The NDB Cluster SQL node package has a dependency on the Perl
Class::MethodMakermodule. Yum can take care of this dependency if the EPEL (Extra Packages for Enterprise Linux) repository has been enabled on your system; see the instructions here for how to enable the EPEL repository. -
The MySQL Yum repository supports installation of MySQL NDB Cluster only for release 7.5.6 and later, and only for EL6 and EL7 platforms. For other methods of installing NDB Cluster, see Installation of NDB Cluster on Linux, or Installation of NDB Cluster on Linux, depending on the release series that you are using.
-
Adding the MySQL Yum Repository for MySQL NDB Cluster
Follow the steps in Adding the MySQL Yum Repository to add the MySQL Yum repository to your system's repository list. If you have already performed the step before, make sure you have the most up-to-date version of the release package by running the following command, for platforms that are not dnf-enabled:
shell> sudo yum update mysql57-community-releaseFor dnf-enabled systems:
shell> sudo dnf --refresh upgrade mysql57-community-release -
Selecting the MySQL NDB Cluster Subrepository
Within the MySQL Yum repository (http://repo.mysql.com/yum/), the MySQL Community Server and MySQL NDB Cluster are hosted in different subrepositories. By default, the subrepository for the latest GA series of the MySQL server is enabled and the subrepository for MySQL NDB Cluster is disabled. To install NDB Cluster, disable the subrepository for the MySQL server and enable the subrepository for NDB Cluster. If your platform supports the yum-config-manager or dnf config-manager command, you can do that by issuing, for example, the following commands, which disable the subrepository for the MySQL 5.7 series and enable the one for the MySQL NDB Cluster 7.5; for platforms that are not dnf-enabled:
shell> sudo yum-config-manager --disable mysql57-community shell> sudo yum-config-manager --enable mysql-cluster-7.5-communityFor dnf-enabled platforms:
shell> sudo dnf config-manager --disable mysql57-community shell> sudo dnf config-manager --enable mysql-cluster-7.5-communityBesides using yum-config-manager or the dnf config-manager command, you can also select a subrepository by editing manually the
/etc/yum.repos.d/mysql-community.repofile. This is a sample entry for the MySQL 5.7 subrepository in the file:[mysql57-community] name=MySQL 5.7 Community Server baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/6/$basearch/ enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysqlTo install NDB Cluster 7.5, you must disable the MySQL 5.7 subrepository by making
enabled=0for the above subrepository entry and enable the NDB Cluster 7.5 subrepository by makingenabled=1for its entry:[mysql-cluster-7.5-community] name=MySQL Cluster 7.5 Community baseurl=http://repo.mysql.com/yum/mysql-cluster-7.5-community/el/6/$basearch/ enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysqlAfter saving the changes to the file, verify that the correct subrepositories have been enabled by running the following command (for dnf-enabled systems, replace yum in the command with dnf):
shell> yum repolist enabled | grep mysql !mysql-cluster-7.5-community/x86_64 MySQL Cluster 7.5 Community 18 !mysql-connectors-community/x86_64 MySQL Connectors Community 31 !mysql-tools-community/x86_64 MySQL Tools Community 33The subrepository for NDB Cluster 7.5 (Community edition) has now been enabled. Also in the list are a number of other subrepositories of the MySQL Yum repository that have been enabled by default.
-
Installing MySQL NDB Cluster
For a minimal installation of MySQL NDB Cluster, follow these steps (for dnf-enabled systems, replace yum in the commands with dnf):
-
Install the components for SQL nodes:
shell> sudo yum install mysql-cluster-community-serverAfter the installation is completed, start and initialize the SQL node by following the steps given inStarting the MySQL Server.
If you choose to initialize the data directory manually using the
mysqld --initializecommand (seeInitializing the Data Directory Manually Using mysqld for details), arootpassword is going to be generated and stored in the SQL node's error log; see MySQL Server Initialization for how to find the password, and for a few things you need to know about it.
-
Install the executables for management nodes:
shell> sudo yum install mysql-cluster-community-management-server -
Install the executables for data nodes:
shell> sudo yum install mysql-cluster-community-data-node
-
-
Configuring and Starting MySQL NDB Cluster
See Initial Configuration of NDB Cluster on how to configure MySQL NDB Cluster and Initial Startup of NDB Cluster on how to start it for the first time.
For EL7-based platforms: See Compatibility Information for EL7-based platforms.
Installing Additional MySQL NDB Cluster Products and Components
You can use Yum to install individual components and additional products of MySQL NDB Cluster from the MySQL Yum repository. To do that, assuming you already have the MySQL Yum repository on your system's repository list (if not, follow Step 1 and 2 of Installing MySQL NDB Cluster Using the Yum Repository), follow the same steps given in Installing Additional MySQL Products and Components.
Known issue: Currently, not all components required for running the MySQL NDB Cluster test suite are installed automatically when you install the test suite package (mysql-cluster-community-test). Install the following packages with yum install (or dnf install for dnf-enabled systems) before you run the test suite:
-
mysql-cluster-community-auto-installer -
mysql-cluster-community-management-server -
mysql-cluster-community-data-node -
mysql-cluster-community-memcached -
mysql-cluster-community-java -
mysql-cluster-community-ndbclient-devel
Platform Specific Notes
ARM Support
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:
shell> yum-config-manager --enable ol7_software_collections
shell> yum install mysql-community-serverARM 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.
