Passenger on CentOS, problems with passenger-memory-stats

I was having difficult running passenger-memory-stats, I was getting:

/usr/local/lib/ruby/gems/1.8/gems/passenger-2.0.2/bin/passenger-memory-stats:145:in `list_processes': Invalid options. (ArgumentError)
from /usr/local/lib/ruby/gems/1.8/gems/passenger-2.0.2/bin/passenger-memory-stats:107:in `start'
from /usr/local/lib/ruby/gems/1.8/gems/passenger-2.0.2/bin/passenger-memory-stats:214
from /usr/bin/passenger-memory-stats:19:in `load'
from /usr/bin/passenger-memory-stats:19


After googling around, I found a post that said:

For those on CentOS/RHEL change line 107 in /usr/local/lib/ruby/gems/1.8/gems/passenger-2.0.2/bin/passenger-memory-stats from:

apache_processes = list_processes(:exe => PlatformInfo::HTTPD)

to

apache_processes = list_processes(:exe => 'httpd.worker')

This worked like a charm!

Passenger Rocks

I set up Phusion Passenger which makes obsolete all the work I did for different Mongrel setups on my Capistrano scripts. It's amazing how much work I have done in my career that has now been made obsolute by something cooler. I still think FoxPro was the best.

Some notes to anyone setting up passenger. For CentOS, we had to install the package httpd-devel. The passenger setup script does the rest, you copy a few lines into your main http configuration file and it's good to go.

Here's my new configuration with SSL (names have been changed to protect my employer.) Note, my rails directory is /var/www/myrails/current:
