我试图连接到mysql工作台，但是我收到以下错误
错误消息无法连接到数据库服务器
用户＆root;＆＃39;您的连接尝试失败从主机到服务器127.0.0.1:3306：无法打开数据库。
请：1。检查mysql是否在服务器127.0.0.1上运行
Check that mysql is running on port 3306 (note: 3306 is the default, but this can be changed)
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).
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.
我在workbench.help me
中安装了mysql服务器
