django + uwsgi + nginx 配置问题汇总

1、DisallowedHost at /admin Invalid HTTP_HOST header: '119.45.124.33:8011'. You may need to add '119.45.124.33' to ALLOWED_HOSTS.

解决方法：
修改项目中的 setting.py 文件

ALLOWED_HOSTS = ['*']  ＃在这里请求的host添加了*

2、E45: 'readonly' option is set (add ! to override)

解决方案， :wq!强制关闭文件后，在命令行里输入：sudo !!后回车。

3、** Operational MODE: preforking+threaded *** failed to open python file wsgi.py unable to load app 0 (mountpoint='') (callable not found or import error) *** no app loaded. going in full dynamic mode ***

上述报错是由于uwsgi.ini 配置文件中的项目路径配置错误导致
chdir 是项目的绝对路径
wsgi-file 是wsgi.py相对于chdir路径的相对路径
例如：新建Django项目Test，绝对路径是 /home/user_001/Test，wsgi.py的路径是 /home/user_001/Test/Test/wsgi.py 。
那么配置如下：

chdir = /home/user_001/Test
# 注意Test前不要加 /
wsgi-file = Test/wsgi.py 

4、Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.

一般是etc/nginx/nginx.conf 配置不符合规则，使用 sudo nginx -t检查

5、# nginx: [emerg] “server” directive is not allowed here

etc/nginx/nginx.conf 的配置中，server需要放在http里面

events {
    ...
}
http {
    ...
    server {
        ...
    }
}
