how to put nodejs and apache in the same port 80
提问by user1203334
I have to put nodejs in port 80, but apache is already using it. How can I put both (nodejs and apache) on the same port 80? I need it because in my university all the ports are blocked except for PORT 80. (This is a realtime application with nodejs and socket.io (websockets) and in the other side a php application). Thanks a lot
我必须将 nodejs 放在端口 80，但 apache 已经在使用它。如何将（nodejs 和 apache）都放在同一个端口 80 上？我需要它，因为在我的大学中，除了 PORT 80 之外，所有端口都被阻止了。（这是一个带有 nodejs 和 socket.io（websockets）的实时应用程序，另一边是一个 php 应用程序）。非常感谢

I've personally done this the other way round from @liammclennan. Some suggestthat proxying through Apache defeats some of the performance and scalability advantages of Node (don't have experience myself as my server doesn't get that much traffic, but from @liammclennan's link: "Every request that comes in through Apache will cause an Apache thread to wait/block until the response is returned from your Node.js process.", which obviously doesn't mesh well with Node's architecture.)
我个人已经从@liammclennan 反过来做了这件事。有些人认为通过 Apache 代理会破坏 Node 的一些性能和可扩展性优势（我自己没有经验，因为我的服务器没有获得那么多流量，但来自 @liammclennan 的链接：“通过 Apache传入的每个请求都会导致一个 Apache 线程等待/阻塞，直到从您的 Node.js 进程返回响应。”，这显然与 Node 的架构不匹配。）
I used node-http-proxyto set up a Node proxy server roughly as described in the first link (my Node proxy runs on port 80; Apache and my other Node services don't). Seems to be working well so far, though I have had occasional stability problems that I've 'solved' through checking the proxy's still running with a cron job (edit:it seems a lot more stable these days). The proxy's pretty lightweight, taking up about 30MB memory.
我使用node-http-proxy大致按照第一个链接中的描述设置了一个 Node 代理服务器（我的 Node 代理在端口 80 上运行；Apache 和我的其他 Node 服务没有）。到目前为止似乎运行良好，尽管我偶尔会遇到稳定性问题，我通过检查代理是否仍在使用 cron 作业运行来“解决”（编辑：这些天似乎更稳定了）。代理非常轻巧，占用大约 30MB 内存。

I do this via node.js proxy..
我通过 node.js 代理执行此操作..
Install http-proxywith npmor official page
安装http-proxy使用npm或官方网页
Example:
例子：
var http = require('http'),
httpProxy = require('http-proxy'),
proxyServer = httpProxy.createServer ({
hostnameOnly: true,
router: {
'domain.com': '127.0.0.1:81',
'domain.co.uk': '127.0.0.1:82',
'127.0.0.1': '127.0.0.1:83'
}
});
proxyServer.listen(80);
This creates a node process listening to port 80, and forwarding requests for domains which go to :81,82,83 etc. I recommend running this with foreverand adding an entry to init.dso your proxy is up in case system shuts down.
这将创建一个节点进程侦听端口 80，并转发对 :81,82,83 等域的请求。我建议运行它forever并添加一个条目，init.d以便您的代理在系统关闭时启动。

You can also use Apache 2's mod_proxy and mod_proxy_http, which might be more reliable or perform better depending on your system.
您还可以使用 Apache 2 的 mod_proxy 和 mod_proxy_http，它们可能更可靠或性能更好，具体取决于您的系统。
Here's an example:
下面是一个例子：
# Use Apache for requests to http://example.com/
# but use Node.js for requests to http://example.com/node/
<VirtualHost *:80>
ServerName example.com
DocumentRoot /var/www/example/
<Location /node>
ProxyPass http://127.0.0.1:8124/
ProxyPassReverse http://127.0.0.1:8124/
</Location>
</VirtualHost>
And of course you can modify the directives to your needs, such as using a different port for your virtual host (e.g., 443), different port for Node.js, or set up the proxy under a different block, such as for a subdomain (e.g., node.example.com).
当然，您可以根据需要修改指令，例如为虚拟主机使用不同的端口（例如 443），为 Node.js 使用不同的端口，或在不同的块下设置代理，例如为子域（例如，node.example.com）。

You can't. You have to run node.js on another port and then proxy requests through apache. You can do this using mod_proxy
你不能。您必须在另一个端口上运行 node.js，然后通过 apache 代理请求。您可以使用 mod_proxy 执行此操作

I found a cool gist Run apache and nodejs on port 80. did not try it yet but will do of course
我发现了一个很酷的要点Run apache and nodejs on port 80。还没有尝试，但当然会做
Step 1
Get a VPS that offers 2or more IP addresses.
Step 2
From the WHM cPanel, find the menu item
Service Configuration, selectApache Configurationand then click onReserved IPs Editor.Step 3
Tick the IP address you DON'T WANTApache to listen to, and write it down so you can use it in the next step. Click
Save.Step 4
Install Node.js, and create a server like this:
var http = require('http'); var server = http.createServer(function(req, res) { res.writeHead(200); res.end('Hello, world!'); }); server.listen(80, '111.111.111.111');Replacing
111.111.111.111with the IP address you previously reserved from the WHM cPanel.Step 5
Stop wasting your time and never listen to those telling you to use
mod_rewriteto proxy Node.js again.
第1步
获取提供2 个或更多 IP 地址的 VPS 。
第2步
从 WHM cPanel 中，找到菜单项
Service Configuration，选择Apache Configuration然后单击Reserved IPs Editor。第 3 步
勾选您的IP地址不想阿帕奇听，并把它写下来，这样你可以在下一步中使用它。单击
Save。第四步
安装 Node.js，然后像这样创建一个服务器：
var http = require('http'); var server = http.createServer(function(req, res) { res.writeHead(200); res.end('Hello, world!'); }); server.listen(80, '111.111.111.111');替换
111.111.111.111为您之前从 WHM cPanel 保留的 IP 地址。第 5 步
停止浪费你的时间，永远不要听那些告诉你
mod_rewrite再次使用 代理 Node.js 的人。
Update:
更新：
We can solve a problem in many different ways and IMHO, we should at least know each possible way . We can do it without buying a new IP of course putting a proxy in front of both Apache and NodeJS server each running other ports except 80.
我们可以用许多不同的方式解决问题，恕我直言，我们至少应该知道每一种可能的方式。我们可以在不购买新 IP 的情况下做到这一点，当然，在 Apache 和 NodeJS 服务器前面放置一个代理，每个服务器都运行除 80 之外的其他端口。
