JADDOG

Coldfusion was the first programming language that actually did something with. I haven’t been writing it too much latley (yay django) but I still have code written in coldfusion that is faithfully running. I love open source and saw a while back that railo was going open source and being shipped with jboss. Went to the Railo site recently and found that Railo 3.1 had in fact been released so I thought I’d give it a spin. Rail 3.1 is downloadable with a copy of resin. I’d not ever heard of resin, seems like a lighter-weight java app server kind like jboss. Hope that’s not too far off base from what it really is. So here’s my experience getting Railo 3.1 to run on CentOS 5.3.

When you first download you need to compile… Found a post that said to download the railo-resin-no-jre and get sun’s jre, of course after I tried it with the jre and couldn’t get mod_coucho to compile. So in the root of what I unpacked (this assumes that you’ve installed things to build with):

$ ./configure –with-java-home=/usr/java/jre1.6.0_15

Got a warning on java JNI not existing. Couldn’t figure it out quicly but I think this is just performance related. Skipping it for now as I don’t need the performance yet. After configuring I ran make and make install. Going to use apache, the main compile didn’t seem to compile the apache module so did that. (this is the piece that failed when I tried to use the included jre) Also copied it to apache’s modules dir.

$ cd modules/c/src/apache2/
$ make all
$ cp .libs/mod_caucho.so /etc/httpd/modules

Now configure apache to use railo. I use virtual hosts heavily so went ahead a configured a couple to test with.

/etc/httpd/conf.d/railo.conf

LoadModule caucho_module modules/mod_caucho.so
DirectoryIndex index.cfm index.php index.htm index.html index.html.var
ResinConfigServer localhost 6800
<VirtualHost *>
ServerName site1.local
</VirtualHost>
<VirtualHost *>
ServerName site2.local
</VirtualHost>
<Location /caucho-status>
SetHandler caucho-status
</Location>

The resin config file had defaults that would use virtual hosting if you just create the proper directory structure. This is done in the root of what was unpacked.

$ mkdir -p hosts/site1.local/webapps/ROOT
$ mkdir -p hosts/site2.local/webapps/ROOT

I also stuck an index.cfm file in each root directory for testing… just a cfoutput with #now()# in it and a site identifier. The hosts/${domainname}/webapps/ROOT structure I think is the standard directory resin expects to do the virtual hosting. Finally start resin.

$ bin/httpd.sh start

I’ve used all the defaults here. There’s some docs on the virtual hosting stuff here. My next step is to integrate it with my existing server setup to see if I can customize this to the point I’d consider replacing AdobeCF with RailoCF. I’ve already tested a simple app written in CF7 on it. No problems.
