Ruby - CentOS 5 - Virtualmin 3.49

Hi

I'm trying to follow this guide on setting up Ruby. http://www.virtualmin.com/documentation/id,ruby_on_rails_and_virtualmin/

I've installed all the required packages.

I can install without setting up database. If I choose to use the mysql database for the virtual server, the install errors out.

[code:1] Now installing Ruby on Rails version 1.2.5 ..

Rails MySQL driver install failed : Select which gem to install for your platform (i386-linux) 1. mysql 2.7.3 (mswin32) 2. mysql 2.7.1 (mswin32) 3. mysql 2.7 (ruby) 4. mysql 2.6 (ruby) 5.

There is an oddity with the MySQL shared libraries on CentOS - they are not in a directory that Ruby looks in.

The fix is to login as root via SSH and install manually with the command :

gem install mysql -- --with-mysql-include=/usr/include/mysql --with-mysql-lib=/usr/lib/mysql

The go back into Virtualmin and re-try the Rails install.
