django.db.utils.OperationalError: (2003, "Can't connect to MySQL server on '10.0.70.109' ([Errno 111] Connection refused)")

这个错误表示 Django 无法连接到 MySQL 服务器。可能是因为 MySQL 服务器未启动或者防火墙阻止了访问。以下是一些解决方法：

1. 检查 MySQL 服务器是否已经启动。如果没有启动，请使用正确的命令启动 MySQL 服务器。

2. 检查 MySQL 服务器的 IP 地址和端口是否正确。确认 IP 地址和端口是否与 Django 配置文件中的设置相同。

3. 检查是否有防火墙阻止了 MySQL 服务器的访问。如果有防火墙，请确保在防火墙中开放了 MySQL 服务器的端口。

4. 如果您使用的是云服务器，可能需要配置安全组规则以允许对 MySQL 服务器的访问。

5. 如果您使用的是 Docker 容器，可能需要检查容器网络设置是否正确。

希望这些解决方法能够帮助您解决问题。

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.

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

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. The error code 111 suggests that the connection was refused, possibly due to a misconfiguration or a network issue.

To resolve this issue, you can try the following steps:

1. Check if the MySQL server is running and accessible from the local machine. You can use the command line tool `mysql` to connect to the server and verify its status.

2. Verify the connection settings in the Django settings file (`settings.py`). Make sure that the database name, user, password, and host are correctly configured.

3. Check if there are any firewall rules or security settings that might be blocking the connection. You may need to open the necessary ports or grant permissions to the MySQL server.

4. If you are using a virtual environment or container, make sure that the MySQL client library is installed and accessible.

5. Try restarting the MySQL server and/or the Django application to see if the connection issue is resolved.
