Answer 1

Check the Nginx的错误日志：error.log，具体日志在什么地方根据系统、安装方式不同都不同，只有你自己知道了。
CentOS下默认是在/var/log/nginx/catalog.

Answer 2

Just looking at this, I don’t know what the problem is. You can open the error log and look at the error log to locate the problem.

Answer 3

I didn’t see a clear error message through the error log. The author can ask on stackoverflow.
If you have solved the problem, you can reply and let us all know what is wrong
