Hello, I don’t know if this is really the right forum to be asking about Rails deployment, but just in case someone has experience with this… I’m attempting to deploy a rails site for the first time, using mongrel, mongrel clusters, and capistrano. So far, I have been able to deploy the files to the site and start up the mongrel server, viewing the files on port 3000. The problem happens when I go to fire up the clusters. From the command line, they appear to be running fine, showing up when I do a ‘ps aux | grep mongrel’. But when I try to view in a browser, they don’t show up. I have add to my httpd.conf file to look like this: \ ServerName [dev.mydomain.com](http://dev.mydomain.com) ServerAlias [dev.mydomain.com](http://dev.mydomain.com) DocumentRoot /var/www/html/dev/mydomain/current/public ProxyPass / [http://127.0.0.1:80](http://127.0.0.1:80) ProxyPassReverse / [http://127.0.0.1:8000](http://127.0.0.1:8000) ProxyPreserveHost on The symlink setup by Capistrano works, so I don’t think it’s that. One strange thing: At one point, the files were visible on the 8000-80003 ports, but I noticed they were pointing to a specific cap release. Once that release was cleaned up from the subsequent file releases, the pages broke. I only mention this because, although I’ve redone the cap setup, I wonder if this is a related issue that still remains. fyi, here are some of the reference i’m using: [mongrel.rubyforge.org/docs/mongrel\_cluster.html](http://mongrel.rubyforge.org/docs/mongrel_cluster.html) [mongrel.rubyforge.org/docs/apache.html](http://mongrel.rubyforge.org/docs/apache.html) [capify.com](http://capify.com) [peepcode.com](http://peepcode.com) I’m really new to to rails deployment, so any thoughts/feedback are appreciated. ---

In the spirit of checking the obvious, what does your mongrel\_cluster.yml file say ? Fred ---

Thanks for the response. the yml looks like this: user: mongrel cwd: /var/www/html/dev/mydomain/current log\_file: log/mongrel.log port: “8000” environment: production group: mongrel address: 127.0.0.1 pid\_file: tmp/pids/mongrel/pid servers: 2 I’m still trying to retrace my steps of why it’s there, but I also have a yml file in my etc/mongrel\_cluster/ directory titled .yml with the same config. raph On Oct 4, 11:35 am, Frederick C.

The file in /etc/mongrel\_cluster should be a symbolic link to the mongrel\_cluster.yml file in your config dir. I’m also using mod\_proxy\_balancer for several production sites and I would recommend you check that option out.
