NGINX 加载网站失败

Question

我有一个 nginx 站点侦听端口 8000。我有一个 Apache 侦听端口 80。

当我尝试加载 nginx 站点时，日志中显示此错误：

2019/03/27 20:13:06 [alert] 7845#7845: 1024 worker_connections are not enough
2019/03/27 20:13:06 [error] 7845#7845: *17498 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 127.0.0.1, server: erp.example.com, request: "GET / HTTP/1.0", upstream: "http://127.0.0.1:8000/", host: "erp.example.com"

浏览器默认显示 502 页面，位于“/opt/bench/bench-repo/bench/config/templates”文件夹。

这里可能有什么问题？

这是完整的 nginx.conf 文件：

upstream erpnext-frappe {
    server 127.0.0.1:8000 fail_timeout=0;
}

upstream erpnext-socketio-server {
    server 127.0.0.1:9000 fail_timeout=0;
}

        # text/html is always compressed by HttpGzipModule
}

我已经与安装了此应用程序并运行的虚拟机进行了比较，结果几乎相同。不同之处在于，在另一台机器上，nginx 正在侦听端口 80 和 python 在端口 8000 上。

感谢任何帮助。

编辑：

我已将位置/配置更改为：

location / {
                try_files $uri $uri/ =404;
        }

也就是说，我删除了代理传递配置，现在 nginx 尝试加载站点，但是错误是 "forbidden":

*23053 directory index of "/opt/bench/erpnext/sites/" is forbidden

如何在 NGINX 中解决这个问题？

Answer 1

我已经解决了

解决方法是设置nginx监听其他端口，比如8020，然后重启服务器。

重启后我检查 python 开始监听 8000 端口和 8020 端口的 nginx。

这样就成功了。我真的不知道为什么 python 正在侦听端口 8000 以及如何更改它，但现在没关系了。
