本文详细阐述了在遇到MySQL服务器无法远程连接时，如何通过修改配置文件和授权用户来解决错误2003和1130的问题。包括了如何启用远程连接、允许特定IP地址访问MySQL服务器，并通过GRANT语句赋予特定用户权限。

ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.1.48' (111)

(1)一开始我使用root用户和mysql服务器ip远程连接，直接报错：

[root@chu Record]# mysql --host=192.168.110.68 --user=root --password
Enter password: 
ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.110.68' (111)

原来是

默认情况下Mysql只允许本地登录，所以需要修改配置文件将地址绑定给注释掉：
vim /etc/mysql/my.cnf
# 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 <---注释掉这一行就可以远程登录了

ERROR 1130 (HY000): Host '192.168.1.22' is not allowed to connect to this MySQL server

(2)修改后继续报错：

  [root@chu Record]# mysql --host=192.168.110.68 --user=root --password
  Enter password: 
  ERROR 1130 (HY000): Host '192.168.56.123' is not allowed to connect to this MySQL server

如果你想允许用户myuser从ip为192.168.1.3的主机连接到mysql服务器，并使用mypassword作为密码
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
