用户管理

create ‘user‘@‘host‘ indentified by ‘PASSWORD‘;

grant all privileges on DB_NAME.TABLE_NAME to ‘user‘@‘host‘ identified by ‘PASSWORD‘;

use mysq;
flush privileges;
select user, host, password from user;

show grants for ‘user‘@‘host‘;

revoke select on test.test1 from ‘USER‘@‘localhost‘;

select * from user where user=‘root‘ \G;
select * from db \G;

忘记密码:

--skip-grant-tables   # 跳过用户设置的权限表, 可以无密码登陆
--skip-network        # 禁止掉网络, 防止被入侵

killall mysqld
mysqld_safe --skip-network --skip-grant-tables &      # 以一个 daemon 的方式重新运行 mysqld
update user set password=password(‘PASSWORD‘) where user=‘root‘;
service restart mariadb

用户密码修改：

? mysqladmin -u USERNAME -h HOSTNAME password ‘NEW_PASS‘ -p
mysql> SET PASSWORD FOR ‘USERNAME‘@‘HOST‘=PASSWORD(‘new_pass‘);
mysql> UPDATE mysql.user SET PASSWORD=PASSWORD(‘new_pass‘) WHERE CONDITION;
