GRANT ALL PRIVILEGES ON *.* TO username@'%' IDENTIFIED BY "password"

分配远程username所有库的访问权限。

 

任何数据库的任何表到用户username使用密码password。

1 GRANT ALL PRIVILEGES ON test_db.* TO user1@192.168.1.3 IDENTIFIED BY "password"<br>2 GRANT ALL PRIVILEGES ON test_db.* TO user2@192.168.1.% IDENTIFIED BY "password"<br>3 GRANT ALL PRIVILEGES ON test_db.* TO user3@192.168.1.0/10 IDENTIFIED BY "password"

很明显，第一句是分配用户user1只能在192.168.1.3上访问。第二句是在192.168.1网段内都能访问。第三句是ip  0-10　　范围内的。

删除用户:

DELETE FROM user WHERE User="username" and Host="localhost";

 

最后别忘了这句.

FLUSH PRIVILEGES;
