設置MySQL容許外網訪問

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

2.登陸數據庫
mysql -u root -p

輸入密碼
mysql> use mysql;

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

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

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

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