Mysql安装配置

先来更新系统

[[email protected] ~]# yum -y update

查看已安装的mysql版本

[[email protected] ~]# rpm -qa | grep mysql

删除上一步查询出来的版本，注意更换这里的版本

[[email protected] ~]# rpm -e --nodeps mysql-libs-5.1.73-7.el6.x86_64

通过yum方式安装mysql

[[email protected] ~]# yum install -y mysql-server mysql mysql-deve

开启mysql服务

[[email protected] ~]# service mysqld start

设置mysql开机自启

[[email protected] ~]# chkconfig mysqld on

设置root用户密码

[[email protected] ~]# mysqladmin -u root password ‘YouPassword‘

登陆mysql

[[email protected] ~]# mysql -u root -p

顺便介绍一下开启root用户的远程访问权限的方法（不安全）

mysql> grant all PRIVILEGES on *.* to [email protected]‘%‘ identified by ‘YouPassword‘;

新建名为scott的数据库

mysql> create database scott;

创建名为scott密码为tiger的用户

mysql> insert into mysql.user(Host,User,Password) values ("%","scott",password("tiger"));

刷新权限

mysql> flush privileges;

使scott用户拥有scott数据库的所有权限

mysql> grant all PRIVILEGES on scott.* to [email protected]‘%‘ identified by ‘tiger‘;

刷新权限

mysql> flush privileges;

退出

mysql> exit;
