Rpm包安装mysql，使用包如下：
Percona-Server-client-55-5.5.38-rel35.2.el6.x86_64.rpm
Percona-Server-devel-55-5.5.38-rel35.2.el6.x86_64.rpm
Percona-Server-server-55-5.5.38-rel35.2.el6.x86_64.rpm
Percona-Server-shared-55-5.5.38-rel35.2.el6.x86_64.rpm
 
安装完成后，做些初始配置
cp /usr/share/percona-server/my-small.cnf/etc/my.cnf
 
/usr/bin/mysqld_safe --user=mysql
 
[root@oel65 ~]# ps aux|grep mysql
/bin/sh /usr/bin/mysqld_safe --user=mysql
/usr/sbin/mysqld --basedir=/usr--datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --user=mysql--log-error=/var/lib/mysql/oel65.err --pid-file=/var/lib/mysql/oel65.pid--socket=/var/lib/mysql/mysql.sock --port=3306
 
UPDATE mysql.user SET password=PASSWORD('123---')WHERE User='root';
 
停库
/usr/bin/mysqladmin shutdown
 
 
解压
tar xvfz Percona-Server-5.6.19-rel67.0-618.Linux.x86_64.tar.gz
mvPercona-Server-5.6.19-rel67.0-618.Linux.x86_64 Percona-Server-5.6.19
 
升级
