1 登录mysql mysql -h host -u username -p password 2 切换至mysql库 use mysql; 3 查看当前允许登录IP及用户 select Host,User from user; 4 删除不必要而表中存在的IP和用户 DELETE FROM user WHERE User='username' and Host='host'; (host值为“%”或空表示所有IP都可登录,一般来说此类行需要删掉) 5 增加需要而表中没有的IP和用户 GRANT
1. 测试是否允许远程连接 $ telnet 192.168.1.8 3306 host 192.168.1.4 is not allowed to connect to this mysql server 2. 允许特定客户端 ip 地址连接 $ mysql -u root -p Enter password: mysql> use mysql mysql> GRANT ALL ON *.* to root@'192.168.1.4' IDENTIFIED BY 'your-root-pas
1. 先确认阿里云是否放开了3306权限 (开启阿里云服务器端口) 2. 连接linux,登录数据库:mysql -uroot -p 修改root用户远程登录权限: 想myuser使用mypassword从任何主机连接到mysql服务器的话 myuser是你的用户名,mypassword是你的密码 use mysql; GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
