代理、Apache、Tomcat - VHosts

2024-6-14 • tag-icon

我的设置如下：

互联网 -- 路由器 -[DMZ]- pfSense -- 网络服务器

router =jenky 塑料廉价路由器（我的 mikrotik/routerboard 坏了）。已将 pfSense 的 IP 地址设置为 DMZ。

pfsense =执行基本的防火墙和代理/反向代理。代理用于将 URL 转发到防火墙后面的正确 Web 服务器。

webserver =centos box 运行 httpd（apache）和 tomcat6（分别安装，均由 yum 安装，但安装时间不同，因此不是 apache+tomcat 的问题）。

有多个网站由这个特定的网络服务器运行，由 apache 的虚拟主机处理。

ex: http://www.somesite.com, http://www.mysite.com, etc

Tomcat 在扩展名 /mywebapp 的端口 8080 上运行一个应用程序。

ex: http://www.somesite.com:8080/mywebapp

我已经适当地配置了所有内容，pfsense以将 apache 提供服务的网站的所有子域转发到正确的主机。

我已配置 /etc/httpd/conf/httpd.conf 以包含虚拟主机配置

<VirtualHost *:80>
    ServerName mywebapp.somesite.com
    ProxyPass / http://www.somesite.com:8080/mywebapp
    ProxyPassReverse / http://www.somesite.com:8080/mywebapp
    ProxyRequests Off
    <Proxy http://www.somesite.com:8080/mywebapp*>
        Order deny,allow
        Allow from all
    </Proxy>
    ErrorLog logs/mywebapp.somesite.com-error_log
    CustomLog logs/mywebapp.somesite.com-access_log common
</VirtualHost>

我已经修改了我的 tomcat6server.xml文件并将第一个连接器更改为包含proxyName和proxyPort。

<!-- A "Connector" represents an endpoint by which requests are received
    and responses are returned. Documentation at :
    Java HTTP Connector: /docs/config/http.html (blocking & non-blocking)
    Java AJP  Connector: /docs/config/ajp.html
    APR (HTTP/AJP) Connector: /docs/apr.html
    Define a non-SSL HTTP/1.1 Connector on port 8080
-->
<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           proxyName="mywebapp.somesite.com"
           proxyPort="8080"
           redirectPort="8443" URIEncoding="UTF-8"/>

无论我尝试什么，当我将其放入mywebapp.somesite.com浏览器时，它都会重定向到mywebapp.somesite.com:8080/mywebapp。

当我想以访问它mywebapp.somesite.com并让它停留在浏览器地址栏中时。这将使 URL 发布更加友好，等等。

我已经CNAME配置DNS了mywebapp。

www.somesite.com不受影响。

的日志httpd看起来正常……tomcat6 的日志什么都没显示。我知道请求击中了正确的框，因为www.somesite.com:8080/mywebapp它有效（以及其他网站）。

iptables已被禁用，所以如果SELinux。

我做错了什么？请指教。

UPDATE:我尝试ProxyPreserveHost On按照其中一条注释添加 vhost 配置，但无济于事。添加此行并重新启动 apache 和 tomcat 后，我无法访问mywebapp.somesite.comnor www.somesite.com:8080/mywebapp。基本上，添加此配置会使 mywebapp 完全无法访问，但我知道它仍在运行。

UPDATE 2:添加从服务器获取的 tcpdump。我显示了从pfsense（代理）传递到的第一个连接webserver。

我粗略地将其解释为：

browser (internet) --> request hits router --> passes DMZ --> hits pfsense...

pfsense > webserver: Uh, here's this HTTP request... for a mywebapp.somesite.com? Do we know a mywebapp.somesite.com?
webserver > internet: Sup, I heard you were looking for some HTTP? I've got some mywebapp.somesite.com.
internet > webserver: Ya, I head about you. Gimme somea dat mywebapp.somesite.com.
webserver > internet: Ha, just kidding, man. I've really got some mywebapp.somesite.com:8080/mywebapp, you dig?
internet > webserver: WTF? Are you serious!?
webserver > pfsense: Dude, I told you we needed more mywebapp.somesite.com, this guy's pissed!
internet > webserver: Hmm... OK, just give me what ya got of mywebapp.somesite.com:8080/mywebapp. I dig.
webserver > internet: Phew! If you dig, I dig... you dig? Here's some HTTP.
internet > webserver: Ah ya, now we're talking. Gimme some more of that /mywebapp/static/.../style.css from Referer: http://mywebapp.somesite.com:8080/mywebapp
webserver > internet: Take it in my man, take it all in. It's all OK.
internet > webserver: Alright, gimme some more of that /mywebapp/static/.../color.css from Referer: http://mywebapp.somesite.com:8080/mywebapp
etc, etc, etc...
