What is mod_ruby?

mod_ruby embeds the Ruby interpreter into the Apache web server, allowing Ruby CGI scripts to be executed natively. These scripts will start up much faster than without mod_ruby.

1) Install eRuby

# wget http://www.modruby.net/archive/eruby-1.0.5.tar.gz
# tar -xzvf eruby-1.0.5.tar.gz
# cd eruby-1.0.5/
# ./configure.rb –with-charset=euc-jp –enable-shared
# make; make install

2) Install mod_ruby

i)Download latest mod_ruby tar file
# wget http://www.modruby.net/archive/mod_ruby-1.2.6.tar.gz
# tar -xzvf mod_ruby-1.2.6.tar.gz
# cd mod_ruby-1.2.6/
#  ./configure.rb –enable-eruby –with-apxs=/usr/local/apache/bin/apxs
# make; make install

ii)Edit apache configuration file ( httd.conf) and add following code

LoadModule ruby_module libexec/mod_ruby.so
ClearModuleList
AddModule mod_ruby.c
AddHandler cgi-script .rb
<IfModule mod_mime.c>

# for Ruby/eRuby
<IfModule mod_ruby.c>
# for Apache::RubyRun
RubyRequire apache/ruby-run
# for Apache::ERubyRun
RubyRequire apache/eruby-run
# for development
# RubyRequire auto-reload
# for add library
#RubyAddPath /usr/local/lib/ruby
# exec *.rbx as ruby scripts.
<Files *.rbx>
SetHandler ruby-object
RubyHandler Apache::RubyRun.instance
</Files>
# handle *.rhtml as eruby files.
<Files *.rhtml>
SetHandler ruby-object
RubyHandler Apache::ERubyRun.instance
</Files>
</IfModule>
</IfModule>

iii) Restart apache service on server
