MySQL数据库赋予用户权限

2021-03-21  本文已影响0人  乂尤先生

MySQL清空数据库的操作:

truncate table tablename;

远程登录MySQL:

mysql -h ip -u root -p 密码

创建用户:

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

例1:增加一个test1用户,密码为123456,可以在任何主机上登录,并对所有数据库有查询,增加,修改,删除的功能。需要在mysql的root用户下进行

grant select,insert,update,delete on *.* to test1@"%"  identified by "123456"

例2:增加一个test2用户,密码为123456,只能在本地登录,并对数据库有查询,增加,修改和删除的功能,需要在MySQL的root用户下进行

grant select,insert,update,delete on *.* to test2@"192.168.1.%" identified by "123456"

例3: 授权用户test3拥有数据库testdb的所有权限

grant all privileges on testdb.* to test3@localhost identified by "123456"

授权用户创建表,索引,视图,存储过程,函数等权限

授权test1用户创建,修改,删除数据表结构权限

grant create on *.* to test1@'%' ;
grant alter on *.* to test1@'%';
grant drop on *.* to test1@'%';

授权test1用户操作MySQL外键权限

grant references on *.* to test1@'%';

授权test1 用户操作MySQL临时表权限

grant create temporary tables on *.* to test1@'%';

授权test1 用户操作MySQL索引权限

grant index on *.* to test1@'%';

授权test1用户操作MySQL视图,查看视图源代码权限

grant create view on *.* to test1@'%';
grant show view on *.* to test1@'%';

授权test1用户操作MySQL存储过程,函数权限

grant create routine on *.* to test1@'%';
grant alter routine on *.* to test1@'%';
grant execute on *.* to test1@'%';

查看用户权限:

查看当前用户权限

show grants;

查看其它用户权限

show grants for test1@localhost;

修改用户密码:

update mysql.user set password=password('123456') where User='test1' and Host='localhost'

删除用户:

delete from user where user='test2' and host='localhost'

删除账户及权限

drop user 用户名@'%'
drop user 用户名@localhost
