采用rpm安装
检查是否有默认安装
[root@owenz /]# rpm -qa | grep mysql
mysql-libs-5.1.66-2.el6_3.x86_64
卸载默认安装
[root@owenz /]# rpm -emysql-libs-5.1.66-2.el6_3.x86_64
error: Failed dependencies:

[root@owenz ~]# rpm -e --nodepsmysql-libs-5.1.66-2.el6_3.x86_64

PLEASE REMEMBER TO SET A PASSWORD FOR THEMySQL root USER !
To do so, start the server, then issue thefollowing commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h owenzpassword 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option ofremoving the test
databases and anonymous user created bydefault. This is
strongly recommended for productionservers.
See the manual for more instructions.
Please report any problems at http://bugs.mysql.com/
生成my.cnf
服务器端安装完成之后，在/usr/share/mysql目录中会生成一个mysql启动脚本mysql.server和一些示例配置文件，其中有一个配置文件my-medium.cnf，因为mysql安装完成之后就默认成为系统服务，所以这里需要将配置文件放在系统服务的相关目录下.
[root@owenz mysql]# cp/usr/share/mysql/my-medium.cnf /etc/my.cnf
启动mysql服务
[root@owenz mysql]# service mysql start
Starting MySQL.. [ OK ]
关闭mysql服务
[root@owenz mysql]# service mysql stop
Shutting down MySQL. [ OK ]
