Apache / Tomcat / Mod_jk Help !

[adamf]

Hello,

I have a FC5 box, running apache 2 and tomcat.

I have a webapp located at /usr/local/tomcat/webapps/app

using the URL http://server.co.uk:8080/app the jsp and servlets all work fine.

I have a domain name abc.co.uk pointed at the server

its in apache httpd.conf and works ok.

But, to view the app, i have to use abc.co.uk/app

What i want is to be able to go to abc.co.uk and see the app

If i go to abc.co.uk i get the tomcat test start page

This is driving me crazy !!

http.conf:

<VirtualHost x.x.x.x>
ServerName www.abc.co.uk
DocumentRoot /usr/local/tomcat/webapps/app/
DirectoryIndex index.jsp
JKMount /* default
</VirtualHost>

Please, any help would be great

thanks you

Bumping this old thread because I have exactly the same question. I'm trying to map subdomains to webapps deployed in Tomcat, e.g.

app1.example.org --> example.org:8080/app1
app2.example.org --> example.org:8080/app2
etc.

I've configured mod_jk in Apache and I'm able to map URLs under the subdomain to Tomcat, but I have not found a way to map URLs under one subdomain to one Tomcat context, URLs under another subdomain to another Tomcat context. Is this possible?

Many thanks

Google "apache web redirect"

[joshsh]

Thanks, but an HTTP redirect isn't what I'm looking for. I want to map requests internally from Apache to Tomcat.

This can be done via one of the many Apache redirect options (client or server side) and it can be done with a combination of DNS entries and iptables/redirection (those two I know will work.)

As for mod_jk, all of the options needed appear to be listed in the Tomcat mod-jk HowTo.

Thanks for the suggestions, though I don't know what you had in mind re: "DNS entries and iptables/redirection". DNS records for all subdomains are of course pointing at the same server. There are only two ports in question: 80 for Apache (open) and 8080 for Tomcat (not open). I never found a straightforward way to get mod_jk to do what I need (hiding the context of each webapp in Tomcat), although apparently it can be done. In the end, mod_proxy provided a simple (if not the best in terms of performance) solution:

NameVirtualHost *:80
<VirtualHost *:80>
    ServerName app1.example.org
    <Location />
        ProxyPass         http://127.0.0.1:8080/app1/
        ProxyPassReverse  http://127.0.0.1:8080/app1/
    </Location>
</VirtualHost>
<VirtualHost *:80>
    ServerName app2.example.org
    ...
</VirtualHost>
...

You can also create two hosts on Tomcat side localhost:8080 (for app1)
and app2:8080 (for app2). Rename your applications to ROOT.war and do not include context element explicitly.

Now you can point mod_jk directly to root of those hosts and it work fine.

The only problem that I have with this setup is that I still need localhost:8080/app1 as local endpoint

maybe I will have to go back to localhost:8080/app1 and use the mod_proxy as you did...
