lighttpd作为反向代理 [英] lighttpd as reverse-proxy

问题描述

DeviceA充当反向代理，并应按以下方式转发请求:

DeviceA serves as a reverse-proxy and is supposed to forward requests as follows:

192.168.1.10/DeviceB ==> 192.168.1.20/index.html

192.168.1.10/DeviceC ==> 192.168.1.30/index.html

两个索引文件都位于/var/www下，并且都是静态的"Hello world！".页面.问题是我无法通过DeviceA访问这些文件，但是如果我调用也在DeviceC上运行的测试服务(在端口12345上监听)，一切正常.

Both index files are located under /var/www and are static "Hello world!" pages. The problem is that I can't access those files through DeviceA, but if I call a test service also running on DeviceC (listening on port 12345) everything works fine.

我是不是说DeviceB，DeviceC上的Web服务器应该在端口80上发出请求时用index.html进行响应?

Am I wrong saying that the web server on DeviceB, DeviceC should respond with index.html if a request comes in on port 80 ???

lighttpd.conf DeviceA @ 192.168.1.10 server.modules =("mod_proxy")

lighttpd.conf DeviceA @192.168.1.10 server.modules = ( "mod_proxy" )

proxy.server = ( 
"/DeviceB" => ( "" => ( "host" => "192.168.1.20", "port" => 80 )),
"/DeviceC" => ( "" => ( "host" => "192.168.1.30", "port" => 80 )),  
"/TestService" => ( "" => ( "host" => "192.168.1.30", "port" => 12345 ))
)

lighttpd.conf DeviceB @ 192.168.1.20

server.document-root = "/var/www"
server.port = 80
index-file.names = ( "index.html" )

lighttpd.conf DeviceC @ 192.168.1.30

server.document-root = "/var/www"
server.port = 80
index-file.names = ( "index.html" )

更新

在proxy.server()周围是否需要$ HTTP ["host"] == ...来重写/重定向URL?或者，如何定义应代理的内容

Do I need $HTTP["host"] == ... around proxy.server() to rewrite/redirect URLs? Or, how to define what shall be proxy(ed)

推荐答案

Lighttpd开发人员已经知道您的需求已有几年了.

Your need is known by lighttpd developers from several years.

可以通过变通方法或新功能来回答，具体取决于版本.

It is answered by a workaround or new feature depending on the version.

Lighttpd 1.4

错误跟踪程序中介绍了一种解决方法:错误#164

A workaround is explained in the bugtracker : bug #164

$HTTP["url"] =~ "(^/DeviceB/)" {   
  proxy.server  = ( "" => ("" => ( "host" => "127.0.0.1", "port" => 81 ))) 
}

$SERVER["socket"] == ":81" {   
  url.rewrite-once = ( "^/DeviceB/(.*)$" => "/$1" )   
  proxy.server  = ( "" => ( "" => ( "host" => "192.168.1.20", "port" => 80 ))) 
}

Lighttpd 1.5

他们通过以下命令添加了此功能(官方文档):

They added this feature with this command (official documentation) :

proxy-core.rewrite-request :重写请求标头或请求uri.

proxy-core.rewrite-request : rewrite request headers or request uri.

$HTTP["url"] =~ "^/DeviceB" {
  proxy-co...

  proxy-core.rewrite-request = (
    "_uri" => ( "^/DeviceB/?(.*)" => "/$1" ),
    "Host" => ( ".*" => "192.168.1.20" ),
  )
}
