MySQL数据库权限操做

操做对象：

线上和测试全部MySQL Plus数据库

建立用户：

create user 'testname'@'%' identified by '123456';

查看testname用户的权限

show grants for testname;

testname用户受权：

GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, PROCESS, REFERENCES, INDEX,ALTER,SHOW DATABASES, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, EVENT, TRIGGER ON *.* TO 'testnam'@'%';

#建立用户并受权

GRANT ALL PRIVILEGES ON *.* TO 'testname'@'%'IDENTIFIED BY '123456' WITH GRANT OPTION;

testname用户原有权限：

SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, PROCESS, REFERENCES, INDEX,ALTER,SHOW DATABASES, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, EVENT, TRIGGER

查看用户的受权权限：

select * from mysql.user where User='testname' and Host='%'\G;

修改用户的受权权限：

update mysql.user set Grant_priv='Y' where User='testname' and Host='%';

flush privileges;

回收权限：

CREATE,DROP,ALTER

revoke CREATE,DROP,ALTER on *.* from testname@'%';

线上受权testname1：

GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, PROCESS, REFERENCES, INDEX, ALTER, SHOW DATABASES, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, EVENT, TRIGGER ON *.* TO 'testname1'@'%';

mysqladmin -u testname1 -h1.1.1.1 password C123456 "c123456"

修改密码：

set password = password 'C123456';
