設置MySQL允許外網訪問

1.修改配置文件
sudo vim /etc/mysql/my.cnf
把bind-address參數的值改成你的內/外網IP或0.0.0.0,或者直接注釋掉這行.

2.登錄數據庫
mysql -u root -p

輸入密碼
mysql> use mysql;

3.查詢host
mysql> select user,host from user;

4.創建host
如果沒有"%"這個host值,就執行下面這兩句:
mysql> update user set host='%' where user='root';
mysql> flush privileges;

5.授權用戶
任意主機以用戶root和密碼mypwd連接到mysql服務器
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'mypwd' WITH GRANT OPTION;
mysql> flush privileges;

IP為192.168.1.102的主機以用戶myuser和密碼mypwd連接到mysql服務器
mysql> GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.102' IDENTIFIED BY 'mypwd' WITH GRANT OPTION;
mysql> flush privileges;

 

 

PS：以上為授權方法，以下為改表方法：

mysql> use mysql;
mysql> update user set host='%' where user='root';
mysql> flush privileges;
