【问题描述】：

我在 Cloud Run 中使用 Django、uwsgi 和 nginx。

Cloud Run 服务无法显示 django 日志记录和错误日志。这就是为什么Error Report 也不能使用的原因。

Cloud Run 日志是这样的。它看不到堆栈跟踪...我不知道服务器发生了什么错误。

这是我的设置。

Django 设置.py

# Graceful stop, see http://nginx.org/en/docs/control.html
stopsignal=QUIT

Cloud Run 获取 /var 和 /dev 目录日志，对吗？ document

为什么此设置无法获取 django 日志记录结果和错误日志，例如 500 错误。

我是这样写loggin的。

logger = logging.getLogger(__name__)
logge.info('hello world')

但是在 Cloud Run 的日志中看不到这个日志。

请帮帮我！

【问题讨论】：

@John Hanley 谢谢你的想法。我添加了logging.shutdown() 但是我看不出日志之前的区别。

【参考方案1】：

我发现了我的错误。我没有在 nginx.conf 中更改server_name

我更改了文件格式的这一行

server_name .example.com;

到

server_name MY_DOMAIN;

然后更新 Cloud Run。我现在可以看到错误日志了！

错误报告也可以正常工作！

这是否意味着没有连接nginx？
