< 备份地址 [root@localhost liuzhen]# mysql -h292.168.1.180 -uroot -p123456 lmcmsv4.0 < lmcmsv4.0.sql 第二种方式：source 备份地址 查看表结构 show create table cms_user; 授权 例1、增加一个用户user001密码为123456，让他可以在任何主机上登录，并对所有数据库有查询、插入、修改、删除的权限。首先用以root用户连入MySQL，然后键入以下命令： mysql>

Grant select,insert,update,delete on *. * to user001@ "%" Identified by "123456"

Example 2. Add a user's user002 password of 123456, so that this user can only log in on localhost, or set a specified IP, and query, insert, modify and delete the database test (localhost refers to the local host, that is, the host where the MySQL database is located).

In this way, even if the user knows the password of user_2, he cannot access the database directly from the Internet, and can only operate the test library through the MYSQL host.

First use the root user to connect to MySQL, and then type the following command:

Mysql > grant select,insert,update,delete on test.* to user002@localhost identified by "123456"
