如何运行节点。js在端口80上吗?

My aim is to run Node.js on port 80. This is because I am finding node.js is being blocked from certain networks which do not allow traffic from any other port.

我的目标是运行Node。js在端口80上。这是因为我找到了node。js正被某些不允许从任何其他端口传输的网络阻塞。

It appears that the best way to do this is by proxying Apache through Node.js. I have tried using node-http-proxy to do this but I have not had any luck.

看起来最好的方法是通过Node.js来代理Apache。我尝试过使用node-http-proxy来实现这一点，但是我没有任何运气。

The code I am using is here:

我使用的代码如下:

var util = require('util'),
    http = require('http'),
    httpProxy = require('http-proxy');

httpProxy.createServer(9000, 'localhost').listen(80);

http.createServer(function (req, res) {
  res.writeHead(200, { 'Content-Type': 'text/plain' });
  res.write('request successfully proxied to: ' + req.url + '\n' + JSON.stringify(req.headers, true, 2));
  res.end();
}).listen(9000);

But I keep getting the error "Address in use" for port 80. I must be doing something wrong.

但我一直得到80端口的错误“使用地址”。我一定是做错了什么。

How do I proxy Apache through node.js using node-http-proxy? Will this enable me to run node.js on port 80? And is node-http-proxy the best way to achieve this?

如何通过节点代理Apache。js使用node-http-proxy ?这会让我运行node吗?js在端口80上吗?node-http-proxy是实现这一目标的最佳方式吗?

Thank you.

谢谢你！

What you need to do is have 2 ip's for the server you are running. Apache has 1 ip bound to port 80 and then node.js has the other ip bound to port 80.

您需要做的是为正在运行的服务器设置两个ip。Apache有1个ip绑定到80端口，然后是节点。js将另一个ip绑定到端口80。

Using node and its listen directive has 2 values eg. .listen(80, NODEJS_IP or DNS NAME);

使用node及其listen指令有2个值，如.listen(80, NODEJS_IP或DNS名称);

Some other advice.

其他一些建议。

I would not use apache with nodejs as it's not evented. So this really isn't recommended. I would actually look into using NGINX as its a much better pairing with Node.

我不会使用带有nodejs的apache，因为它没有被调用。这是不推荐的。我会考虑使用NGINX作为与Node更好的配对。

run your app on a high port 8080 or whatev then

运行你的应用程序在一个高端口8080或什么

sudo iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080

If you are not using ngnix or apache

如果您不使用ngnix或apache

The simplest solution: safely configure your node app to run on port 80.

最简单的解决方案:安全配置节点应用程序，使其在端口80上运行。

sudo apt-get install libcap2-bin
sudo apt-get安装libcap2-bin
sudo setcap cap_net_bind_service=+ep /path/to/node
sudo setcap cap_net_bind_service = + ep /道路/ /节点
Ta da! You're done.
助教哒!你就完成了。

It is currently not recommended to run node on port 80, as that requires running node as root.

目前不建议在端口80上运行node，因为这需要以root身份运行node。

How attached are you to apache? Proxying node through nginx is a tried and true solution, with an nginx-config such as this:

你对apache有多依恋?通过nginx的代理节点是一个可靠的解决方案，具有如下的nginx-config:

upstream node_cluster {
    ip_hash;   
    server 127.0.0.1:8000;
    server 127.0.0.1:8001;
    server 127.0.0.1:8002;
}

server {
    listen 0.0.0.0:80;
    server_name foo;
    access_log /var/log/nginx/foo.log;

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

      proxy_pass http://node_cluster/;
      proxy_redirect off;
    }
}

Your code looks like example code in which you're creating a Node-based proxy from port 80 to port 9000, and then creating a Node-based HTTP server on port 9000. (i.e. Node:80 -> Node:9000)

您的代码看起来像示例代码，其中您正在从端口80到端口9000创建基于节点的代理，然后在端口9000上创建基于节点的HTTP服务器。(即节点:80 - >节点:9000)

You are getting "address in use" when you launch Node because Apache is already using port 80. If you want to use Apache to proxy, you must use Node on a different port (say 9000) and have Apache listening on port 80 and forwarding the requests to Node on port 9000. (i.e. Apache:80 -> Node:9000)

当您启动节点时，您将获得“使用中的地址”，因为Apache已经在使用端口80。如果希望使用Apache进行代理，则必须在另一个端口(比如9000)上使用Node，并让Apache监听端口80，并将请求转发到端口9000上的Node。(例如Apache:80 - >节点:9000)

It looks like the library you're using is for doing the opposite: using Node as the proxy and forwarding requests to Apache. In this case you must configure Apache to run on another port than port 80. (i.e. Node:80 -> Apache:9000).

看起来您正在使用的库的用途恰恰相反:使用节点作为代理并将请求转发给Apache。在这种情况下，您必须配置Apache在另一个端口上运行，而不是端口80。(即节点:80 - > Apache:9000)。

Are you wanting to do Node:80 -> Apache:9000 or Apache:9000 -> Node:80, in the end?

您是想做节点:80 -> Apache:9000还是Apache:9000 ->节点:80，最后呢?

EDIT after comments: If you want to do Apache:80 -> Node:9000, you can use mod_proxy on Apache and use the ProxyPass/ProxyPassReverse directives, something like

编辑注释后:如果您想做Apache:80 ->节点:9000，您可以在Apache上使用mod_proxy，并使用ProxyPass/ProxyPassReverse指令，类似这样的操作

ProxyPass /nodeurls/ http://localhost:9000/
ProxyPassReverse /nodeurls/ http://localhost:9000/

where nodeurls is the family of URLs you wish for Apache to forward to Node.

nodeurl是您希望Apache转发到Node的url的家族。
