fiona@fiona:~$ mysql -h 10.112.4.136
ERROR 1045 (28000): Access denied for user 'fiona'@'10.112.1.85' (using password: NO)
fiona@fiona:~$ mysql -h 10.112.4.136 -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'10.112.1.85' (using password: YES)
一直都在报错
使用mysql5.7
按照教程打开MySQL数据库远程访问的权限,报错依然没有解决
- 查看root权限,没有问题
mysql> show grants for 'root'@'%';
+-------------------------------------------------------------+
| Grants for root@% |
+-------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION |
+-------------------------------------------------------------+
1 row in set (0.00 sec)
- 怀疑密码不对,查看密码
发现5.7版本的列名不是password
mysql> select user,host,password from mysql.user;
ERROR 1054 (42S22): Unknown column 'password' in 'field list'
- 查看user列表,获得列名
mysql> desc mysql.user;
