这个错误通常是由于 MySQL 服务器未启动或者连接参数不正确导致的。您可以尝试以下几个步骤来解决这个问题:
1. 确认 MySQL 服务器已经启动。您可以在命令行中输入 `mysql -u root -p` 来尝试连接 MySQL 服务器。如果连接成功,则说明 MySQL 服务器已经启动。
2. 确认连接参数是否正确。您需要确认连接参数中的主机名、用户名、密码和端口号是否正确。如果您使用的是默认的配置,主机名应该是 `localhost`,用户名应该是 `root`,密码应该为空,端口号应该是 `3306`。
3. 确认防火墙是否允许连接。如果您的服务器上启用了防火墙,您需要确认防火墙是否允许连接到 MySQL 服务器的端口。默认情况下,MySQL 服务器使用的端口是 `3306`。
如果您仍然无法解决这个问题,请提供更多的信息,例如您使用的操作系统和 MySQL 版本等。

Can't connect to MySQL server on 'localhost'
There could be several reasons why you are unable to connect to the MySQL server on 'localhost'. Here are a few possible solutions you can try:
1. Check if the MySQL server is running: Make sure that the MySQL server is up and running on your localhost. You can check the status of the server by running the command `service mysql status` or `systemctl status mysql` (depending on your operating system).
2. Verify the connection parameters: Double-check the connection parameters such as the host, port, username, and password. Ensure that you are using the correct values to establish the connection.
3. Check the firewall settings: If you have a firewall enabled on your machine, make sure that it allows incoming connections on the MySQL port (default is 3306). You may need to configure your firewall to allow access to the MySQL server.
4. Verify MySQL server permissions: Ensure that the user you are trying to connect with has the necessary privileges to access the MySQL server from 'localhost'. You can use the `GRANT` statement to grant appropriate permissions if needed.
5. Restart the MySQL server: Sometimes, restarting the MySQL server can resolve connectivity issues. You can do this by running the command `service mysql restart` or `systemctl restart mysql`.
If none of these solutions work, please provide more information about your setup and any error messages you are encountering for further assistance.
