rpm -e --nodeps mysql
// 强力删除模式，如果使用上面命令删除时，提示有依赖的其它文件，则用该命令可以对其进行强力删除

yum list | grep mysql
//查看yum上提供的mysql数据库可下载的版本

yum install -y mysql-server mysql mysql-devel
//将mysql mysql-server mysql-devel都安装好

rpm -qi mysql-server //查看刚安装好的mysql-server的版本

//启动 mysql

service mysqld start

service mysqld restart

//设置mysql开机自启动

chkconfig --list | grep mysqld

chkconfig mysqld on

/usr/bin/mysqladmin -u root password 'root' // 为root设置密码

// 允许root用户远程访问

use mysql;

update user set host='%' where user='root';

flush privileges;
