Question

Resin - IIS and multiple JVMs

Asked by: vonRogue

Hello Experts,

I recently installed Resin 3.1.9 on Windows Server 2008 to serve Coldfusion files with Railo 3.1.0.12. This is my first experience with anything Java, and my question is how do I have each Virtual Host use a different JVM? Right now, all of my sites are using one instance, and when I change anything in resin.conf, the server has to reload. I've read through the documentation on the caucho website, but it's sorely lacking when it comes to how to implement this.

My current folder structure is similar to the following for my two sites:

c:\websites\site1\wwwroot
c:\websites\site2\wwwroot

I've placed the isapi_srun.dll in c:\inetpub\scripts, which is also mapped as the virtual directory "scripts" for each of the sites.

Both of my sites are working correctly with Resin, but I just want them each to run their own instance. How do I go about doing this? Do I need to manually create a scripts directory inside both of the sites' wwwroot with a copy of the isapi_srun.dll and include a resin.ini file there? Also, where do the individual site1.conf and site2.conf files go?

Sorry if this isn't very clear. Again, I'm really new to Resin and Java. Please ask me if you need any further explanation

you just need to startup multiple instances of resin with each one using a different port and webapps.
Its unrelated to IIS really.

Thanks for the quick reply, objects. I guess my next question is how resin will know which instance/port to use for each site? Where do I save my site1.conf and site2.conf files, and the resin.ini files?

Right now, I don't have a resin.ini file and I'm just using the default resin.conf file stored in c:\resin\conf\resin.conf. This file contains Host sections for each of my sites.

Caucho's website leads me to believe that I need a separate resin.ini file saved in the Scripts directory for each site, in addition to a ".conf" file for each. Currently, this scripts directory is just a Virtual Directory that contains the isapi_srun.dll file. If I create a resin.ini file there, won't it be the same one for each site that uses the virtual directory? Or am I just overthinking this?

resin.conf

</host>
 
<host id="site2.com" root-directory="C:/websites/site2.com">
	<host-alias>www.site2.com</host-alias>
	<web-app id="/" root-directory="wwwroot"/> 
</host>

so are you running httpd?

 

by: vonRoguePosted on 2009-05-10 at 20:56:03ID: 24351386

Yes, I'm running httpd. IIS is the "front end", but it passes off requests to resin when needed (for .cfm and .jsp files in my case.) I basically followed the installation instructions from here:

http://www.caucho.com/resin-3.1/doc/install-iis.xtp

I setup Resin to run as a service using those instructions as well. Again, everything is working correctly, but is only using 1 JVM.

Here's what I would like to accomplish...
http://www.caucho.com/resin-3.1/doc/install-iis.xtp#Virtual%20Sites%20with%20different%20JVM%27s

I'm just not sure where to store the resin.ini files and the site1.conf and site2.conf files.

 

by: objectsPosted on 2009-05-10 at 21:08:50ID: 24351419

httpd has an option you can pass it to tell it the resin home to use

http://www.caucho.com/resin-3.0/install/cse-iis.xtp#Command-line-arguments

you want to startup mutliple instances of httpd pointing at different directories
