installing redmine ROR on centos

I just did a dance of success and my co-worker said he never saw anything like that in the workplace.  Anyway, we still use a excel spreadsheet to track our projects, so last night I decided to install redmine and see if that would work for us.  Redmine is a project management tool that runs on the Ruby on Rails stack.  I haven't done much with ROR, but I am pragmatic and this seemed to fit my needs.  I don't have my java blinders on!

Getting it installed was a little difficult.  Redmine recommends Ruby 1.8.7, Rails 2.2 and these are not in the yum repo for centos.  I downloaded and installed ruby from source

wget ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.7.tar.gz

gunzip ruby-1.8.7.tar.gz

tar xvf ruby-1.8.7.tar.gz

cd ruby-1.8.7

./configure

make

make install

I tried starting up redmine:

cd /usr/local/ror/redmine-0.8.4

[root@rhoderunner redmine-0.8.4]# ruby script/server webrick -e production
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- zlib (MissingSourceFile)

To fix this:

cd /usr/local/ror/ruby-1.8.7/ext/zlib

ruby extconf.rb --with-zlib-include=/usr/include --with-zlib-lib=/usr/lib

make

make install

I tried starting it up again:

[root@rhoderunner redmine-0.8.4]# ruby script/server webrick -e production
=> Booting WEBrick...
/usr/local/ror/redmine-0.8.4/vendor/rails/railties/lib/initializer.rb:229:in `require_frameworks': no such file to load -- openssl (RuntimeError)

This time:

yum install openssl openssl-devel

cd /usr/local/ror/ruby-1.8.7/ext/openssl

make

make install

cd /usr/local/ror/redmine-0.8.4

ruby script/server webrick -e production

SUCCESS!

Here is where I did my dance.
