設置mysql允許外網訪問

設置mysql允許外網訪問

需要連接或使用navicat等查看同局域網主機的mysql

1. 修改表

# 切換到mysql數據庫
use mysql;
update user set host = '%' where user ='root';
select host, user from user;
# 使修改生效
flush privileges;

2. 授權用戶,你想root使用密碼從任何主機連接到mysql服務器

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456'  WITH GRANT OPTION;

# 如果你想允許用戶root從ip為192.168.1.104的主機連接到mysql服務器
GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.3.114' IDENTIFIED BY '123456'  WITH GRANT OPTION; 

flush privileges;

3. 如果目標為Linux系統，還要修改my.cnf文件(/etc/mysql/my.cnf)

[mysqld]
bind-address = 0.0.0.0  # 表示允許任何主機登陸MySQL
port=3306               # 表示MySQL運行端口為3306
