在 apache 上运行的服务器上安装 Nodejs 应用程序，该服务器使用带有 nginx 的反向代理

Question

我知道堆栈交换有很多这样的问题。但没有什么可以帮助我遇到的情况。

这是我的情况。

我有一个运行在apache2 上的网络服务器，监听端口号7080 和7081。我在我的服务器上使用了反向代理方法并安装了nginx，它正在监听端口80。所以现在nginx是前端。我的 wordpress 网站在 http://www.example.com 上运行。

现在我正在尝试在我的服务器上安装 node.js 应用程序，但我无法安装。这是有道理的，因为nginx 正在使用端口 80。

我在 SO 上提到了以下帖子

Node.js + Nginx - What now?

Apache and Node.js on the Same Server

我尝试了以下

    upstream example.com/my-app {
    server 1**.*.**.**:3010;
}

# the nginx server instance
server {
    listen 1**.*.**.**:80;
        server_name example.com/my-app;
    server_name www.example.com/my-app;
    server_name ipv4.example.com/my-app;


    access_log off;

    # pass the request to the node.js server with the correct headers and much more can be added, see nginx config options
    location / {
      proxy_set_header Host             $host;
      proxy_set_header X-Real-IP        $remote_addr;
      proxy_set_header X-Forwarded-For  $proxy_add_x_forwarded_for;
      proxy_set_header X-Accel-Internal /internal-nginx-static-location;



      proxy_pass http://example.com/my-app;
      proxy_redirect off;
    }
location /internal-nginx-static-location/ {
        alias      /var/www/vhosts/example.com/httpdocs/node;
        access_log /var/www/vhosts/example.com/httpdocs/node/statistics/logs/proxy_access_ssl_log;
        add_header X-Powered-By PleskLin;
        internal;
    }
 }

我把上面的 conf 写在一个文件中，并包含在 /etc/nginx/conf.d/xzzeaweae_nginx.conf 中。

它不工作。但是该应用程序在 1++.+.++.++:3010 上正常运行。

我的目录结构。

/var/www/vhosts/example.com/httpdocs/

我的 wordpress 网站根目录：/var/www/vhosts/example.com/httpdocs/

我的 nodejs 应用程序目录：/var/www/vhosts/example.com/httpdocs/my-nodejsapp-folder/

更新

这是我的 apache 应用程序的反向代理配置

server {
    listen +++.+.++.++:80 ;
    listen ++.+.+++.++:80 ;

    location / {
        proxy_pass http://127.0.0.1:7080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

由于我的服务器上运行着多个网站，

我为每个网站都有反向代理配置。

这是我的一个网站

    listen +++.+.++.++:443 ssl;

        access_log /var/www/vhosts/example.com/statistics/logs/webmail_access_ssl_log;
    }
}



server {

        internal;
    }
}

server {
    listen +++.+.++.++:80;
    server_name webmail.example.com;

    client_max_body_size 128m;

    location / { # IPv6 isn't supported in proxy_pass yet.

        proxy_set_header Host             $host;
        proxy_set_header X-Real-IP        $remote_addr;
        proxy_set_header X-Forwarded-For  $proxy_add_x_forwarded_for;
        access_log /var/www/vhosts/example.com/statistics/logs/webmail_access_log;
    }
}

注意：sites-available 和 sites-enabled 文件存在于 apache2 中。不在nginx。

我希望我的 nodejs 应用程序在 example.com/my-nodejsapp-folder/ 上运行而无需任何端口号。

任何帮助将不胜感激。

Answer 1

http://nginx.org/en/docs/http/ngx_http_upstream_module.html#upstream

我还没有看到它说你可以在上游名称中使用点和斜杠

upstream mynodeapp {
    server 1**.*.**.**:3010;
}

然后

server {
    listen 1**.*.**.**:80;
    server_name example.com/my-app;

    #...etc.

    location / {
      proxy_set_header Host             $host;
      proxy_set_header X-Real-IP        $remote_addr;
      proxy_set_header X-Forwarded-For  $proxy_add_x_forwarded_for;

      # not this.
      # proxy_set_header X-Accel-Internal /internal-nginx-static-location;

      proxy_pass http://mynodeapp/my-app;
      proxy_redirect off;
    }
 }

那么你的node应用需要写一个header包含：

X-Accel-Redirect: /internal-nginx-static-location/somefile

有一些限制，例如，如果您在返回所有标题之前开始返回内容（例如打印语句），它可能不起作用。仅使用有趣的标头进行首次测试会更简单。

示例：

# /etc/nginx/conf.d/default.conf
upstream mynodeapp {
    server 127.0.0.1:8000;
}

server {
    listen 127.0.0.1:80;

    location /secret {
        alias /tmp/secret;
        internal;
    }

    location /my-app {
        proxy_pass http://mynodeapp/my-app;
    }
}

让我们尝试以下方法：

// /tmp/index.js
var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'X-Accel-Redirect': '/secret/foo'});
  res.end('Hello World\n');
}).listen(8000, '127.0.0.1');

现在是命令行：

[root@localhost secret]# pwd
/tmp/secret
[root@localhost secret]# echo bar > foo 
[root@localhost secret]# curl http://127.0.0.1:80/my-app
bar
[root@localhost secret]# curl http://127.0.0.1:80/secret/foo
<html>
<head><title>404 Not Found</title></head>
<body bgcolor="white">
<center><h1>404 Not Found</h1></center>
<hr><center>nginx/1.0.15</center>
</body>
</html>
[root@localhost secret]#
