如何在单个服务器上处理多个域请求？

Question

I am using dedicated server. I have hosted different HTML, PHP and wordpress websites on this server those are working perfectly.

Now I want to deploy java web application on this server. So I have installed Apache tomcat server on another port. So now I want to know how I can handle request directly from domain name to tomcat apache server.

Along with this I want to know how I can deploy multiple web applications on single tomcat. I want to know configuration to call different WAR files from tomcat.

Thank you in advance for your support.

Answer 1

You can use Apache as reverse proxy with the mod_proxy plugin: http://httpd.apache.org/docs/2.2/mod/mod_proxy.html

Therefore, you can handle all HTTP requests with Apache, specifying which requests shall be redirected to the Java web app in Apache Tomcat - port 8080.

Answer 2

Easiest way is to set up a HTTP server (apache, nginx, etc.) as a reverse proxy. Then you can map different domains to different contexts, for example:

www.domain.com -> localhost:8080/main/
www.otherdomain.com -> localhost:8080/othermain/ 
subdomain.domain.com -> localhost:8080/anotherwar/

For example with Nginx it would be done with a ProxyPass directive. Other HTTP servers have their own respective mechanisms.
