3)、停止数据库

[root@cent65 mysql]# service mysql stop
Shutting down MySQL (Percona Server).......[? OK? ]
[root@cent65 mysql]# mv /var/lib/mysql /var/lib/mysql55

4)、 移动旧数据库(5.5版本)的数据目录(假设是/var/lib/mysql,此处应该改为你自己的数据目录)

[root@cent65 mysql]#mv /var/lib/mysql /var/lib/mysql55

[root@cent65 mysql]#mkdir /var/lib/mysql

[root@cent65 mysql]#chown -R mysql:mysql /var/lib/mysql

三、安装Percona Server 5.6

[root@cent65 percona-56]# ls -l
total 121104
-rwxr-xr-x. 1 mysql mysql 70389368 Dec? 3 11:21 Percona-Server-56-debuginfo-5.6.25-rel73.1.el6.x86_64.rpm
-rwxr-xr-x. 1 mysql mysql? 6727084 Dec? 3 11:21 Percona-Server-client-56-5.6.25-rel73.1.el6.x86_64.rpm

-rwxr-xr-x. 1 mysql mysql 23137340 Dec? 3 11:21 Percona-Server-test-56-5.6.25-rel73.1.el6.x86_64.rpm
-rwxr-xr-x. 1 mysql mysql? 1508480 Dec? 3 11:21 Percona-Server-tokudb-56-5.6.25-rel73.1.el6.x86_64.rpm

Percona server 5.5会与5.6的软件有冲突，所以5.6的安装需要强制安装：

server软件的安装需要先卸载server 5.5：
