ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.111.133' (111)解决办法

如图报错以下：

谷歌了一下以后，原来是在mysql的my.cnf中有下面一段代码：

Instead of skip-networking the default is now to listen only on

localhost which is more compatible and is not less secure.

bind-address = 127.0.0.1 #这里默认监听本地localhost

若是要让mysql监听到其余的地址，能够将bind-address = 127.0.0.1注释掉。

或者将bind-address = 0.0.0.0监听全部的地址

屏蔽掉以后再次运行代码又出现：mysql -h 192.168.111.133 -uroot -p

Enter password:

ERROR 1130 (HY000): Host '192.168.111.133' is not allowed to connect to this MySQL server

如图：

解决方法：

若是想让192.168.10.83可以链接到本地的这个数据库，要让数据库给其分配权限,登陆mysql，执行:(username 和 password是登陆mysql的用户名和密码)

GRANT ALL PRIVILEGES ON . TO 'root'@'192.168.0.111' IDENTIFIED BY 'password' WITH GRANT OPTION;

若是要想全部的外部ip地址都可以访问使用mysql，能够执行下面：

GRANT ALL PRIVILEGES ON . TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;

以后执行刷新数据库：

flush privileges;

知识点：

1：那么咱们来建立一个测试帐号test，授予全局层级的权限。以下所示：

mysql> grant select,insert on . to test@'%' identified by 'test';

Query OK, 0 rows affected (0.01 sec)

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

mysql>

mysql> show grants for test;

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

| Grants for test@%
| +--------------------------------------------------------------------------------------------------------------+

| GRANT SELECT, INSERT ON . TO 'test'@'%' IDENTIFIED BY PASSWORD '*94BDCEBE19083CE2A1F959FD02F964C7AF4CFC29' |

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

1 row in set (0.00 sec)

mysql> select * from mysql.user where user='test'\G;

2：那么咱们来建立一个测试帐号test，授予数据库层级的权限。以下所示：

mysql> drop user test;

Query OK, 0 rows affected (0.00 sec)

mysql> grant select,insert,update,delete on MyDB.* to test@'%' identified by 'test';

Query OK, 0 rows affected (0.01 sec)

mysql>

mysql> select * from mysql.user where user='test'\G; --能够看到无任何受权。

mysql> select * from mysql.db where user='test'\G;

mysql>

mysql> show grants for test;

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

| Grants for test@% |

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

| GRANT USAGE ON . TO 'test'@'%' IDENTIFIED BY PASSWORD '*94BDCEBE19083CE2A1F959FD02F964C7AF4CFC29' |

| GRANT SELECT, INSERT, UPDATE, DELETE ON MyDB.* TO 'test'@'%' |
