我在RHEL服务器7.0中安装了MySQL 5.7.11。我可以使用命令提示符访问数据库，但我无法通过MySQL工作台远程登录它。 my.cnf文件放在/etc文件夹中，看起来像这样

有两种情况可以解决此问题：您尝试连接的计算机未在服务器的防火墙上列入白名单，或者MySQL服务器已关闭
在你的情况下，它可能是一个网络问题，所以这里有一些你想检查的事情：
1-验证每台计算机是否可以ping另一台计算机并验证端口是否已打开（例如，使用Telnet）
2-确保防火墙没有阻止与MySQL侦听端口的连接，如果是这样，请将其添加到防火墙的解锁/例外列表iptables
3-从bind-address = 10.106.100.230文件中删除my.cnf
4-在Unix / Linux论坛中提出你的问题;你会得到更多的帮助
