How to install Mysql 5.6.21 under Centos 6.5 _mysql

Create a directory where you need to download the RPM package package:

# mkdir-p/taokey/tools/

See if the system has a MySQL package if it has been deleted

# rpm-qa|grep MySQL
mysql-libs-5.1.71-1.el6.x86_64
mysql-server-5.1.71-1el6.x86_64
# yum Remove Mysql-server mysql-libs
#rpm-qa|grep MySQL
#

This means that there is no MySQL package if the MySQL has been installed after the removal of the package also need to operate

# Find/-name MYSLQ
/var/lib/mysql
/var/lib/mysql/mysql
/var/lock/subsgs/myslq
# rm-rf/var/lib/ MySQL
# rm-rf/vra/lib/mysql/mysql

Check to see if the MYSLQ installation directory is clean at once

# Find/-name MySQL

Also need to download 3 packages on the website:

Install these three packages:

# RPM-IVH mysql-server-5.6.21-1.rhel5.x86_64.rpm
#rpm-ivh mysql-client-5.6.21-1.rhel5.x86_64.rpm
# RPM-IVH mysql-devel-5.6.21-1.rhel5.x86_64.rpm

If the error is installed Libaio package in the installation

#yum-y Install Libaio
