本地主机上通过端口80访问的不同端口上的Web应用程序

问题描述

我在笔记本电脑的各个目录中都有不同的Web应用程序，因此我可以开始使用侦听不同端口的简单Web服务器.例如

I have different web apps in various directories on my laptop, that I can start using simple webservers listening on different ports. For example

~/app1/./app.pl
>> listening on http://localhost:3000/

~/app2/./app.pl
>> listening on http://localhost:3001/

~/app3/./app.pl
>> listening on http://localhost:3001/

我想像这样从浏览器访问以上内容

I want to access the above from my browser like so

http://localhost/app1
http://localhost/app2
http://localhost/app3

我可以使用mod_proxy进行上述操作吗?如果可以，怎么办?

Can I do the above with mod_proxy? If so, how?

更新:我必须补充说，我已经用Google搜索了mod_proxy，阅读了Apache网站上的教程，并尝试了以下方法

Update: I must add that I have Googled for mod_proxy, read the tutes on Apache's website, and experimented with the following

在我的httpd.conf

uncommented the following in my httpd.conf

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_http_module modules/mod_proxy_http.so

在我的httpd.conf

added the following in my httpd.conf

<IfModule mod_proxy.c>
    ProxyRequests On
    ProxyPass /app1 http://localhost:3000/
    ProxyPassReverse /app1 http://localhost:3000/
    ProxyPass /app2 http://localhost:3001/
    ProxyPassReverse /app2 http://localhost:3001/
    ProxyPass /app3 http://localhost:3002/
    ProxyPassReverse /app3 http://localhost:3002/
</IfModule>

但是，当我尝试访问上述应用时，我会收到HTTP 404.

Yet, I get HTTP 404 when I try to access the above apps.

推荐答案

我将使用mod_rewrite和mod_proxy进行此操作.例如(以下规则进入您的VirtualHost配置):

I would do this using mod_rewrite and mod_proxy. For example (the following rulesgo into your VirtualHost configuration):

RewriteEngine On
RewriteRule ^/app1(.*)$ http://localhost:3000/$1 [P]
RewriteRule ^/app2(.*)$ http://localhost:3001/$1 [P]
RewriteRule ^/app3(.*)$ http://localhost:3002/$1 [P]

这些规则使用mod_rewrite的[P]标志来代理请求.你需要做通过添加/取消注释，确保将mod_proxy，mod_proxy_http和mod_rewrite全部加载到您的主要Apache配置中:

These rules use mod_rewrite's [P] flag to proxy the request. You'll need to makesure that mod_proxy, mod_proxy_http and mod_rewrite are all loaded in your main apache configuration by adding/uncommenting:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule rewrite_module modules/mod_rewrite.so
