leonheart

　　

　　

　　yum install mysql
yum install mysql-server
yum install mysql-devel
chgrp -R mysql /var/lib/mysql
chmod -R 770 /var/lib/mysql
　　service mysqld start
mysql
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('secret_password');
　　

　　

　　1.新建用户。

//登录MYSQL
@>mysql -u root -p
@>密码
//创建用户
mysql> insert into mysql.user(Host,User,Password) values("%","doctrack",password("idoladmin"));
//刷新系统权限表
　　

　　GRANT ALL PRIVILEGES ON *.* TO 'doctrack'@'%' IDENTIFIED BY 'idoladmin' WITH GRANT OPTION;
如果你想允许用户myuser从ip为192.168.1.3的主机连接到mysql服务器，并使用mypassword作为密码
GRANT ALL PRIVILEGES ON *.* TO 'doctrack'@'192.168.1.3' IDENTIFIED BY 'idoladmin' WITH GRANT OPTION;
　　

　　mysql>flush privileges;
