Question

意外删除的conf nginx填充/etc/nginx/sites-enabled/django，然后使用相同的配置设置填充它。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

配置，以前肯定有效。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  {

    }

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

    location / {

    }
}

Answer 1

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，则会出现上游错误。

所以将'app_server'替换为任何其他名称。运行nginx -t检查是否有错误，然后重新启动nginx，

Answer 2

如果您在终端 cat /etc/nginx/nginx.conf 你会看到这两行：

include /etc/nginx/conf.d/*.conf;

<块引用>

这意味着 Nginx 加载所有文件 .conf (for example if you are using dokku to deploy your app, you will see dokku.conf which contain "include /home/dokku/*/nginx.conf;" itself) 这意味着加载所有 /home/dokku/whatever-folder/nginx.conf

include /etc/nginx/sites-enabled/*;

Answer 3

在我的情况下出现此问题，因为我的配置文件在/etc/nginx/conf.d中，并且我在/etc/nginx/sites-enabled/中也有指向它的符号链接。不确定nginx如何加载文件，但显然它已加载两次。无论我为上游选择什么名称，我都会遇到重复错误。删除符号链接可解决此问题。

ngnix - 在/ etc / nginx / sites-enabled / django
