今天安装数据库，使用cmd连接mysql无任何问题，但是使用mysql连接是报错：
<span style="font-size:12px;">[Window Title] MySQL Workbench [Main Instruction] Cannot Connect to Database Server [Content] Your connection attempt failed for user 'root' from your host to server at 127.0.0.1:3306: Can't get hostname for your address Please: 1 Check that mysql is running on server 127.0.0.1 2 Check that mysql is running on port 3306 (note: 3306 is the default, but this can be changed) 3 Check the root has rights to connect to 127.0.0.1 from your address (mysql rights define what clients can connect to the server and from which machines) 4 Make sure you are both providing a password if needed and using the correct password for 127.0.0.1 connecting from the host address you're connecting from [Close]</span>其中错误信息里面有一句：
<span style="font-size:12px;">Can't get hostname for your address</span>找不到我主机 的hostnameGoogle了很多，最终从这个网址
点击打开链接
发现，将连接设置中的Hostname “127.0.0.1”改成：“::1”
即可成功连接到数据库。
如图：
