ngnix - 在 /etc/nginx/sites-enabled/django 中复制上游“app_server”

Question

不小心删掉了 conf nginxfilled /etc/nginx/sites-enabled/django ，然后用同样的配置设置填充。得到以下错误：

  Feb 02 12:56:53 solomon nginx[32004]: nginx: [emerg] duplicate upstream "app_server" in /etc/nginx/sites-enabled/django.save:1
Feb 02 12:56:53 solomon nginx[32004]: nginx: configuration file /etc/nginx/nginx.conf test failed
Feb 02 12:56:53 solomon systemd[1]: nginx.service: Control process exited, code=exited status=1
Feb 02 12:56:53 solomon sudo[31990]: pam_unix(sudo:session): session closed for user root

Feb 02 12:56:53 solomon systemd[1]: nginx.service: Unit entered failed state.
Feb 02 12:56:53 solomon systemd[1]: nginx.service: Failed with result 'exit-code'.

配置，之前肯定有效。我做错了什么吗？：

 upstream app_server {
    server 127.0.0.1:9000 fail_timeout=0;
}

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /usr/share/nginx/html;
    index index.html index.htm;

    client_max_body_size 4G;
    server_name _;

    keepalive_timeout 5;

    # Your Django project's media files - amend as required
    location /media  {
        alias /home/django/django_project/django_project/media;
    }

    # your Django project's static files - amend as required
    location /static {
        alias /home/django/django_project/django_project/static; 
    }

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_pass http://app_server;
    }
}

如果目录( /etc/nginx/sites-enabled/django) 中有其他配置文件，其上游名称与“app_server”相同，那么您会收到重复的上游错误。

因此，将“app_server”替换为任何其他名称。运行nginx -t以检查任何错误，然后重新启动 nginx，
