Apache/Glassfish recipe for running multiple apps on a single host

  • 772

I'm trying to set up Apache + Glassfish so that I can access two different webapps on the same physical host, differentiated by the hostname in the URL.

So if I visit http://host1.com, I'll get app1. If I visit http://host2.com, I'll get app2. host1 and host2 both resolve to the same IP address.

I've been able to get this working in a basic way with mod_proxy and Glassfish virtualservers using this guide. But the user still needs to specify the context-root for one of the apps, i.e. http://host1.com/app1.

How can I set things up so that both apps appear as the "root" in their respective URLs?

Do I need two separate Glassfish domains?

Here's the apache config I'm using:

<VirtualHost *:80>
     ProxyPreserveHost On
     ProxyPass / http://localhost:8080/app1
     ProxyPassReverse / http://localhost:8080/app1
     ServerName host1.com
</VirtualHost>

<VirtualHost *:80>
     ProxyPreserveHost On
     ProxyPass / http://localhost:8080/
     ProxyPassReverse / http://localhost:8080/app2
     ServerName host2.com
</VirtualHost>

    I was close. Here's what ended up working:

    Create a 2nd domain:

    • $ asadmin create-domain --portbase 5000 --profile developer mydomain
    • $ asadmin start-domain mydomain

    Deploy both apps to the context root in their respective domains. You specify domain by giving the admin port:

    • $ asadmin deploy --contextroot "/" target/app1.war # domain1
    • $ asadmin deploy --contextroot "/" --port 5048 target/app2.war # mydomain

    The new domain will run on port 5080, so configure mod_proxy to use that:

    <VirtualHost *:80>
     ProxyPreserveHost On
     ProxyPass / http://localhost:8080/
     ProxyPassReverse / http://localhost:8080/
     ServerName host1.com
</VirtualHost>

<VirtualHost *:80>
     ProxyPreserveHost On
     ProxyPass / http://localhost:5080/
     ProxyPassReverse / http://localhost:5080/
     ServerName host2.com
</VirtualHost>
