MySQL权限设置

本机访问权限：

mysql> GRANT ALL PRIVILEGES ON *.* TO 'username'@'localhost' IDENTIFIED BY 'password';

远程访问权限：

mysql> GRANT ALL PRIVILEGES ON *.* TO 'username'@'%' IDENTIFIED BY 'password';

FLUSH PRIVILEGES;

增加用户 test1 密码 abc,让它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：

 格式： grant select on 数据库.* to 用户名@登录主机 identified by "密码"

 grant select,insert,update,delete on *.* to test1@"%" Identified by "abc";

删除用户

drop user root@localhost;（@不加默认为“%”）

权限回收

revoke delete on test.* from admin@'localhost';

授权精确到列

grant select (cur_url,pre_url) on dataname.table_name to admin@localhost;

限制用户资源

mysql> GRANT ALL ON customer.* TO 'francis'@'localhost'

-> IDENTIFIED BY 'frank'

-> WITH MAX_QUERIES_PER_HOUR 20

-> MAX_UPDATES_PER_HOUR 10
