URL重定向/同样的Java Web应用到多个子域映射

问题描述

我有一个域名，比如www.domain.com。我已经开发了一个Java Web应用程序，说JWA。现在，我想用子域安装针对不同客户相同的应用程序，什么是最好的解决方案成为可能？

I've a domain, say www.domain.com. And I've developed a java web application, say jwa. Now I want to install the same app for different clients using subdomains, what is the best solution possible?

像client1.domain.com指向CLIENT1（已更名为JWA）

something like "client1.domain.com" points to "client1" (renamed jwa)

我知道我们能得到client1.domain.com/client1/但CLIENT1两次不好。或者至少我们可以得到client1.domain.com/jwa/，无有多个Tomcat实例？顺便说一句，我在同一台服务器上运行的Apache HTTP服务器，并使用proxy_module的Java / Tomcat的应用

I know we can get client1.domain.com/client1/ but client1 twice isn't good. or at least Can we get client1.domain.com/jwa/, without have multiple tomcat instances? btw, I'm running apache http server on the same server and using "proxy_module" for java/tomcat apps

问候

推荐答案

您不需要多个Tomcat实例 - 你可以点多个客户端跨多个子域使用相同的Web应用程序

You dont need multiple Tomcat instances - you can point multiple clients across multiple subdomains to use the same web app

但要确保这符合您的业务用例 - 即你实际的想要的web应用程序的多个实例的运行，还是可以的单个实例为所有客户。

BUT be sure that this fits with your business use case - i.e. do you actually want multiple instances of the webapp running, or a can single instance serve all your clients.

我指的是品牌/商标/共享数据/外观和手感等 - 是通用于所有的客户端

I'm referring to the branding/logo/shared data/look-and-feel etc - is that common across all clients?

让我们假设它是。

通过配置Apache的，正确的方法是使用虚拟主机指令与mod_proxy的一起。

With an Apache configured, the right way is to use VirtualHost directives along with mod_proxy.

在Apache的侧像这样的配置应该工作 - 创建每个子之一，并指出了的ProxyPass 和 ProxyPassReverse 到Tomcat Web应用程序

A configuration like this on the Apache side should work - create one per subdomain, and point the ProxyPass and ProxyPassReverse to the Tomcat web app

<VirtualHost *:80>
  ServerName client1.domain.com

  ProxyRequests Off
  ProxyPreserveHost On

  <Proxy *>
    Order deny,allow
    Allow from all
  </Proxy>

  ProxyPass /jwa http://client1.domain.com:8080/jwa
  ProxyPassReverse /jwa http://client1.domain.com:8080/jwa
</VirtualHost>

有也没有Apache的httpd的一个解决方案，可以server.xml中的T​​omcat中配置主机entires但是Apache是​​一个更好的地方来管理您的域的网址

There is also a solution without Apache httpd, you can configure Host entires within Tomcat server.xml but Apache is a better place to manage your domain URLs
