Django运行不提示网址问题

时间：2024-05-07 07:57:45

问题描述：运行django项目不提示网址信息，也就是web没有起来，无法访问。

(my-venv-3.8) PS D:\Project\MyGitCode\public\it_blog\blog> python .\manage.py runserver
INFO autoreload 636 Watching for file changes with StatReloader
Performing system checks...

System check identified no issues (0 silenced).

django运行结果如上，这是一个不正常的结果，没有提示网址访问信息，已经是第2次出现，昨天大约是20分钟左右自动恢复，原因是数据库连接不上：

## 问题排查
一直不提示访问地址是因为Django没有正常启动，可能是因为后台数据库那个时候卡住的原因。

接着我与大师进行了交流，它也给出了一些可能的建议，其中就有提到数据库问题：

  1. Check for errors: Look for any error messages in the console output that might indicate why the server isn’t starting properly. It could be a syntax error in your code, a database issue, or a missing migration.

  2. Verbose output: Run the command with verbosity set to 3 for more detailed output:

    python manage.py runserver --verbosity 3

  3. Restart your environment: If nothing seems to work, try restarting your development environment (terminal, code editor, or even your computer) to reset any processes that might be causing conflicts.

  4. Review project settings: Check if there’s something in your Django project that’s causing issues with the server start-up. It could be in settings.py, middleware, or a custom configuration.

今天还是一样的问题，数据库直接OOM了，无奈之下只能重启了服务器。后期解决方案是迁移数据库服务器，多分配一点资源。
