Different distributions of MySQL are distributed by different parties through their own software repositories or download sites. You can replace a third-party distribution of MySQL using the MySQL Yum repository in a few 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.
Before you can use the MySQL Yum repository for installing (or updating) MySQL, you must stop your system from receiving MySQL packages from any third-party, non-native Yum repositories.
One way to check whether Yum is now receiving third-party MySQL distributions from other repositories is to use the following command:
yum list installed mysql\*
This is a sample output for the command:
mysql.i686 5.1.69-1.el6_4 @updates mysql-libs.i686 5.1.69-1.el6_4 @updates mysql-server.i686 5.1.69-1.el6_4 @updates
The output shows the names of the packages of the third-party
MySQL distribution that are installed and, on the right-hand
side, the repository (which is named
updates, a native repository for the Linux
distribution) from which they were installed.
However, sometimes the names of the packages of the third-party distribution might not contain the string “mysql” in it. It might be useful to search also with this command:
yum --disablerepo=\* provides mysql\*
The following is a sample output of the command:
MariaDB-compat-10.0.4-1.i686 ... ... Repo : installed Matched from: Other : mysql-libs MariaDB-server-10.0.4-1.i686 ... ... Repo : installed Matched from: Other : mysql-server
From the result we can see the names of some of the packages
for the installed third-party distribution of MySQL
MariaDB-compat). To try to get an
exhaustive list of packages installed for this third-party
distribution of MySQL, it might be helpful to search for
installed packages of similar names with, for example, the
yum list installed mariadb\*
This is a sample output for the command:
MariaDB-common.i686 10.0.4-1 @mariadb MariaDB-compat.i686 10.0.4-1 @mariadb MariaDB-server.i686 10.0.4-1 @mariadb
From the command output, we can identify all the installed
MariaDB-server) and the third-party Yum
repository from which they were installed (named
The next step is to stop Yum from receiving packages from the third-party Yum repository:
sudo yum-config-manager --disable mariadb
For platforms like Fedora 19 and 20 that install MySQL from the native repositories, this step is usually not required, unless you have explicitly added a third-party Yum repository for MySQL packages.
Once the third-party Yum repository has been disabled, add the MySQL Yum repository to your system's repository list by following the instructions given in Adding the MySQL Yum Repository.
The installed third-party MySQL distribution must first be uninstalled before you can use the MySQL Yum repository to install MySQL, or the installation process will give an error.
Assuming that, as in the example above, the third-part MySQL
packages you have found are named
MariaDB-server, uninstall them with the
sudo yum remove MariaDB-common MariaDB-compat MariaDB-server
If your third-party MySQL distribution was not installed by Yum or by an RPM installer, you will not be able to detect and then uninstall it by Yum. If you are not sure what to do in that case, consult a system administrator or the original third-party distributor.
Then, install MySQL from the MySQL Yum repository with the following command:
sudo yum install mysql-server
The MySQL server and other components required to run the server, including the client, the shared client libraries, and the common error messages and character sets for client and server, are now installed from the MySQL Yum repository. To install more components for MySQL, see Installing Additional MySQL Products and Components with Yum.
