Percona Server 5.6 is the latest release of drop-in replacement for MySQL®. The new version offers all the improvements found in MySQL 5.6 Community Edition plus scalability, availability, backup, and security features found only in MySQL 5.6 Enterprise Edition, which requires a support contract from Oracle to access. Percona Server 5.6 is free, open source software which includes superior diagnostics and improved integration with other Percona software. In this documentation, I will show how to install Percona Server 5.6 on CentOS 6.
