查询用户表

mysql> select user,host,password from mysql.user;

+------+-----------+-------------------------------------------+

| user | host | password |

+------+-----------+-------------------------------------------+

| root | localhost | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |

| root | node1 | |

| root | 127.0.0.1 | |

| | localhost | |

| | node1 | |

| root | % | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |

+------+-----------+-------------------------------------------+

发现问题了。

先删除node1记录

mysql> delete from mysql.user where host='node1';

Query OK, 2 rows affected (0.05 sec)

mysql> select user,host,password from mysql.user;

+------+-----------+-------------------------------------------+

| user | host | password |

+------+-----------+-------------------------------------------+

| root | localhost | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |

| root | 127.0.0.1 | |

| | localhost | |

| root | % | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |

+------+-----------+-------------------------------------------+

4 rows in set (0.00 sec)

再删除密码为空的记录

mysql> delete from mysql.user where user is null;

Query OK, 0 rows affected (0.01 sec)

mysql> delete from mysql.user where password='';

Query OK, 2 rows affected (0.00 sec)

mysql> select user,host,password from mysql.user;

+------+-----------+-------------------------------------------+

| user | host | password |

+------+-----------+-------------------------------------------+

| root | localhost | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |

| root | % | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |

+------+-----------+-------------------------------------------+

2 rows in set (0.00 sec)

最后对root授权

mysql> grant all privileges on *.* to root@'%' identified by '123456' with grant option;

Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

mysql> exit

Bye

[root@node1 ~]# mysql -h node1 -uroot -p123456
