Mysql远程无法连接

客户端远程连接mysql失败.（mysql server在Ubuntu上）
ip能ping通，telnet ip:3306端口不通 Ubuntu下防火墙已经关闭 sudo ufw disable
Ubuntu ping windwos不通，关闭Windows防火墙后能ping通了
还是连接不上
忘记了MySQL默认禁止#允许所有用户远程访问 修改用户名和密码为你自己的

mysql> GRANT ALL PRIVILEGES ON *.* TO ‘USERNAME‘@‘%‘ IDENTIFIED BY ‘PASSWORD‘ WITH GRANT OPTION; #允许单个ip 修改用户名和密码为你自己的 mysql> GRANT ALL PRIVILEGES ON *.* TO ‘USERNAME‘@‘1.2.3.4‘ IDENTIFIED BY ‘PASSWORD‘ WITH GRANT OPTION; #最后 mysql> FLUSH PRIVILEGES;
