Linux supports a number of different solutions for installing MySQL, covered in Section 2.5, “Installing MySQL on Linux”. One of the methods, covered in this section, is installing from Oracle's Unbreakable Linux Network (ULN). You can find information about Oracle Linux and ULN under http://linux.oracle.com/.
To use ULN, you need to obtain a ULN login and register the machine used for installation with ULN. This is described in detail in the ULN FAQ. The page also describes how to install and update packages. The MySQL packages are in the “MySQL for Oracle Linux 6” and “MySQL for Oracle Linux 7” channels for your system architecture on ULN.
At the time of this writing, ULN provides MySQL 5.6 for Oracle Linux 6 and Oracle Linux 7.
Once MySQL has been installed using ULN, you can find information on starting and stopping the server, and more, in this section, particularly under Section 2.5.5, “Installing MySQL on Linux Using RPM Packages from Oracle”.
If you're updating an existing MySQL installation to an installation using ULN, the recommended procedure is to export your data using mysqldump, remove the existing installation, install MySQL from ULN, and load the exported data into your freshly installed MySQL.
If the existing MySQL installation you're upgrading from is from a previous release series (prior to MySQL 5.6), make sure to read the section on upgrading MySQL, Section 2.11, “Upgrading MySQL”.
