今天登录mysql,给其它用户授权遇到问题
mysql> grant all privileges on testdb.* to ‘dbuser‘@‘10.4.14.14‘ identified by ‘5jyeTQ‘; ERROR 1044 (42000): Access denied for user ‘root‘@‘localhost‘ to database ‘testdb‘
首先看一下root用户有没有grant权限
mysql> select user,host,grant_priv from user; +--------+---------------+------------+ | user | host | grant_priv | +--------+---------------+------------+ | dbuser | 10.11.6.23 | N | | root | localhost | N | | root | 127.0.0.1 | N | +--------+---------------+------------+ 3 rows in set (0.00 sec)
看到root后面那两个N了吗，说明root用户没有grant权限 ，现在修改一下
mysql> update user set grant_priv=‘Y‘ where user=‘root‘; Query OK, 2 rows affected (0.00 sec) Rows matched: 2 Changed: 2 Warnings: 0 mysql> select user,host,grant_priv from user; +--------+---------------+------------+ | user | host | grant_priv | +--------+---------------+------------+ | dbname | 10.11.6.23 | N | | root | localhost | Y | | root | 127.0.0.1 | Y | +--------+---------------+------------+ 3 rows in set (0.00 sec)
现在变成Y了，flush privileges;刷新一下权限 ，然后授权试试
mysql> grant all privileges on testdb.* to ‘dbuser‘@‘10.4.14.14‘ identified by ‘5jyeTQ‘; Query OK, 0 rows affected (0.00 sec)
