  • 1. MySQL 5.6 installation and upgradation. Step by step configuration instructions. ****************************************************************** A MySQL server package (mysql­server­5.0.77­4.el5_5.4) is installed. The current MySQL server package is provided by a different vendor (CentOS) than MySQL AB, Sun Microsystems, Inc., or Oracle and/or its affiliates. Some files may be installed to different locations, including log files and the service startup script in /etc/init.d/. Upgrading directly from MySQL 5.0 to MySQL 5.6 may not be safe in all cases. A manual dump and restore using mysqldump is recommended. It is important to review the MySQL manual's Upgrading section for version­specific incompatibilities. A manual upgrade is required. ­ Ensure that you have a complete, working backup of your data and my.cnf files. ­ Shut down the MySQL server cleanly ­ Remove the existing MySQL packages. Usually this command will  list the packages you should remove:  rpm ­qa | grep ­i '^mysql­'  You may choose to use 'rpm ­­nodeps ­ev <package­name>' to remove  the package which contains the mysqlclient shared library. The  library will be reinstalled by the MySQL­shared­compat package. ­ Install the new MySQL packages supplied by Oracle and/or its affiliates ­ Ensure that the MySQL server is started ­ Run the 'mysql_upgrade' program This is a brief description of the upgrade process. Important details can be found in the MySQL manual, in the Upgrading section. ******************************************************************  Mysql 5.6 RPM Installation steps   [root@test45 /]#rpm ­ivh MySQL­server­5.6.13­1.linux_glibc2.5.x86_64.rpm    [root@test45 /]#rpm ­ivh MySQL­client­5.6.13­1.linux_glibc2.5.x86_64.rpm    [root@test45 /]# rpm ­ivh MySQL­devel­5.6.13­1.linux_glibc2.5.x86_64.rpm       [root@test45 /]#service mysql restart
