前段时间有人提起mysql5.1过时了，于是开始折腾，，，，
升级前请备份
升级脚本:

rpm -ivh http://github.itzmx.com/1265578519/repo/master/CentOS/mysql-community-release-el6-5.noarch.rpm
rm -rf /etc/yum.repos.d/mysql-community.repo
rm -rf /etc/yum.repos.d/mysql-community-source.repo
wget http://github.itzmx.com/1265578519/repo/master/CentOS/mysql-community.repo -O /etc/yum.repos.d/mysql-community.repo
wget http://github.itzmx.com/1265578519/repo/master/CentOS/mysql-community-source.repo -O /etc/yum.repos.d/mysql-community-source.repo
yum -y install mysql mysql-server

最后请修改/etc/my.cnf为mysql5.6的版本，如果升级还是以前5.1的，不通用，可能会导致一些未知问题

vi /etc/my.cnf
