django Network errorlOException: Connectionrefused: connect.

您好！关于Django的网络错误“lOException: Connectionrefused: connect”，通常表示Django应用程序无法连接到数据库。这可能是由于以下几个原因导致的：

1. 数据库服务器未运行：请确保您的数据库服务器已启动并正在运行。您可以尝试通过命令行或管理工具连接到数据库以验证其是否可用。

2. 数据库连接配置错误：检查您的Django项目中的数据库连接配置。确保数据库主机名、端口、用户名和密码等信息正确，并与实际数据库服务器配置一致。

3. 防火墙或安全组设置：如果您的数据库服务器受到防火墙或安全组的限制，可能需要调整相关的配置以允许来自Django应用程序的连接。

4. 数据库访问权限问题：确保您在Django应用程序中使用的数据库用户具有足够的权限来连接和操作数据库。

5. 其他网络问题：尝试通过其他工具或方法（如Telnet）测试与数据库服务器之间的网络连接是否正常。检查网络设置和配置，确保没有其他问题导致连接被拒绝。

请根据上述建议逐一排查可能的原因，并尝试解决问题。如果问题仍然存在，请提供更多详细信息，以便我能够更具体地帮助您解决该问题。

django.db.utils.OperationalError: (2003, "Can't connect to MySQL server on '127.0.0.1' ([Errno 111] Connection refused)")

This error message indicates that the Django application is unable to connect to the MySQL server running on the local machine at IP address 127.0.0.1 (also known as localhost). The connection is being refused, which could be due to a number of reasons such as:

- The MySQL server is not running
- The MySQL server is running on a different port than the default (3306)
- The MySQL server is not configured to accept connections from the Django application
- There is a firewall or network issue preventing the connection

To resolve the issue, you can try the following:

1. Make sure the MySQL server is running and listening on the correct port (usually 3306). You can check this by running "sudo systemctl status mysql" on the command line.
2. Check the MySQL server's configuration file (my.cnf) to ensure that it is set up to accept connections from the Django application's host and port.
3. Ensure that any firewalls or network security groups are configured to allow traffic on the MySQL server's port.
4. Try connecting to the MySQL server from another application or client to see if the issue is specific to Django.
