这就是我的/home/ubuntu/project/nginx.conf好像：

http {

    # configuration of the server
    server {
        # the port your site will be served on
        listen      80;
        # the domain name it will serve for
        server_name ec2-xxx-xxx-xxx-xxx.eu-central-1.compute.amazonaws.com; # substitute your machine's IP address or FQDN
        charset     utf-8;

        # max upload size
        client_max_body_size 75M;   # adjust to taste

        # Django media
        location /media  {
            alias /home/ubuntu/project/media;  # your Django project's media files - amend as required
        }

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

        # Finally, send all non-media requests to the Django server.
        location / {
            uwsgi_pass  unix:///home/ubuntu/project/deploy/web.sock;;
            include     /home/ubuntu/project/deploy/uwsgi_params;
        }
    }
}

当我尝试启动 nginx 时，它抛出一个错误："http" directive is not allowed here in /etc/nginx/sites-enabled/nginx.conf:1

我一直在阅读不同的帖子试图解决这个问题，但没有成功。我还提到如果我删除http { }（所以只留下服务器定义），它可以工作。我究竟做错了什么？

[编辑]忘了说这一点，我建立了一个链接：

sudo ln -s /home/ubuntu/project/nginx.conf /etc/nginx/sites-enabled/nginx.conf

The /etc/nginx/nginx.conf服务器上的文件几乎肯定包含include sites-enabled/*;

include 语句只是将引用文件的内容内联（递归地），因此当 nginx 尝试启动时生成的配置将类似于：

# contents of /etc/nginx/nginx.conf
...
http {
    ...
    # include sites-enabled/*;

    # contents of /etc/nginx/sites-enabled/nginx.conf
    http { # <----------------------   

        # configuration of the server
        server {
            ...
        }
    }
}

我究竟做错了什么？

The http指令 http://nginx.org/en/docs/http/ngx_http_core_module.html#http只能位于主上下文中（即不在任何其他指令中），它不能位于另一个 http 指令中，因此问题中描述的配置是一个致命错误。删除重复的 http 指令会产生有效的配置，从而允许 nginx 启动。
