【问题描述】：

我有一个简单的 django 网站，我正在尝试使用 nginx 和 uwsgi 加载。

当我尝试测试我的 nginx 配置时，我得到以下信息：

$ sudo nginx -t
nginx: [crit] pread() "/etc/nginx/sites-enabled/sites-available" failed (21: Is a directory)
nginx: configuration file /etc/nginx/nginx.conf test failed

我的站点可用/默认配置如下：

# the upstream component nginx needs to connect to
upstream django 
    server 127.0.0.1:8001; # for a web port socket (we'll use this first)


# configuration of the server
server 
    # the port your site will be served on
    listen      80;
    # the domain name it will serve for
    server_name website.com xx.xx.x.x; # substitute your machine's IP address or FQDN
    charset     utf-8;

    # max upload size
    client_max_body_size 2M;   # adjust to taste

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

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

    # Finally, send all non-media requests to the Django server.
    location / 
        uwsgi_pass  127.0.0.1:8001;
        include     uwsgi_params; # the uwsgi_params file you installed
    

我在/var/log/nginx/error.log查看了nginx错误日志，发现：

2019/11/26 14:29:53 [crit] 7702#7702: pread() "/etc/nginx/sites-enabled/sites-available" failed (21: Is a directory)
2019/11/26 15:05:25 [crit] 7736#7736: pread() "/etc/nginx/sites-enabled/sites-available" failed (21: Is a directory)

我还验证了在 nginx 的 sites-available/ 和 sites-enabled 之间建立了符号链接：

$ sudo ln -s /etc/nginx/sites-available/ /etc/nginx/sites-enabled/
ln: failed to create symbolic link '/etc/nginx/sites-enabled/sites-available': File exists

这里可能出了什么问题？

谢谢

【参考方案1】：

您已符号链接目录而不是名为 default 的文件。

sites-enabled 中应该有一个名为default 的文件，它是sites-available 目录中名为default 的文件的符号链接。

试试这个：

cd /etc/nginx/sites-enabled/
rm sites-available;

以上内容应删除导致错误的符号链接。

cd /etc/nginx/sites-enabled/
ln -s ../sites-available/default;

上面应该创建一个名为default的符号链接。

【讨论】：

完成此操作后，启动 nginx，然后启动 uwsgi 我收到 HTTP 502 错误“上游过早关闭连接，同时从上游读取响应标头”？？
