Hi, I have successfully crossed all the hurdles to install Ruby on rails on a redhat 5 Linux based system. But the last and the biggest hurdle i am facing at this moment is installing backgrounrb ☹ I followed all the steps from the [http://backgroundrb.rubyforge.org/](http://backgroundrb.rubyforge.org/) 1. sudo gem install chronic packet 2. script/plugin install svn://rubyforge.org/var/svn/backgroundrb [IMP:::: I had to drop from the step 2 and 3 from the [http://backgroundrb.rubyforge.org/](http://backgroundrb.rubyforge.org/) as the [deviavu.com](http://deviavu.com) system is no longer responding to me and and the git/piston are not supported on my system; dono what exactly are they ☹ ] 3. rake backgroundrb:setup — Successfully created the database.yml under config dir and worker dir under lib. 4. rake db:migrate 5. When started the backgroundrb, I got the following error: ======================================================================= # ./script/backgroundrb/start # /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.3.4/lib/active\_support/depreca tion.rb:17: private method `warn' called for nil:NilClass (NoMethodError) from /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.3.4/lib/active_su pport/deprecation.rb:24:in `call’ from /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.3.4/lib/active\_su pport/deprecation.rb:24:in `warn' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-2.3.4/lib/active_rec ord/connection_adapters/abstract/connection_specification.rb:98:in `allow\_concur rency=’ from ./script/backgroundrb/start:67 MY GEM ENV’s * * * RubyGems Environment: - RUBYGEMS VERSION: 1.3.4 - RUBY VERSION: 1.8.8 (2009-10-09 patchlevel -1) [x86\_64-linux] - INSTALLATION DIRECTORY: /usr/local/lib/ruby/gems/1.8 - RUBY EXECUTABLE: /usr/local/bin/ruby - EXECUTABLE DIRECTORY: /usr/local/bin - RUBYGEMS PLATFORMS: - ruby - x86\_64-linux - GEM PATHS: - /usr/local/lib/ruby/gems/1.8 - /root/.gem/ruby/1.8 - GEM CONFIGURATION: - :update\_sources =\> true - :verbose =\> true - :benchmark =\> false - :backtrace =\> false - :bulk\_threshold =\> 1000 - REMOTE SOURCES: - [http://gems.rubyforge.org/](http://gems.rubyforge.org/) * * * ---

before blaming backgroundrb, make sure your ruby application works in production mode & development mode. Then try to start backgroundrb; it tries load an instance of your rails application and the errors you see might be due to your application. On Oct 15, 6:40 am, Sapna R.

Again, backgroundrb is now on Github. It clearly states on the website to use git to get the latest version. git clone git://github.com/gnufied/backgroundrb.git (into your vendor/ plugins directory) To install git on Redhat? (do you mean fedora?). You can try $ sudo yum install git If that doesn’t work for you, download the source for Git from the web and build it locally. It isn’t that hard to do on Linux. ---

Again after the whole day google search I just figured that out. Copied the package and the backgroundrb under vendor/plugins on my redhat server. Now the real fun started… the git-hub points to the latest gem, but the one mentioned in the website is 0.1.6gem. Again after invading the whole google pages, I was able to get the 0.1.6 gem package and then everything went well. Now when I do the ./script/backgrounrb start, I have couple of issue I. I don’t see any logger lessages. II. Also, if I copy my worker file under lib/workers the backgroundrb fails by complaing about the dependencies ☹ ## Snapshot from the background\_server\*.log /usr/local/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:31:in `gem_original _require': no such file to load -- log_worker (LoadError) from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in`require’ from /usr/local/lib/ruby/gems/1.8/gems/packet-0.1.15/bin/packet\_worker\_r unner:35:in `load_worker' from /usr/local/lib/ruby/gems/1.8/gems/packet-0.1.15/bin/packet_worker_r unner:26:in`initialize’ from /usr/local/lib/ruby/gems/1.8/gems/packet-0.1.15/bin/packet\_worker\_r unner:47:in `new’ from /usr/local/lib/ruby/gems/1.8/gems/packet-0.1.15/bin/packet\_worker\_r unner:47 ---

In this particular case that setting is now a setting with no effect so you could just comment it out from backgroundrb/start, however unless you know what you’re doing I’d really recommend that you get the latest version, as others have advised. > ======================================================================= > > MY GEM ENV’s > > * * * > > RubyGems Environment: > > - RUBYGEMS VERSION: 1.3.4 > - RUBY VERSION: 1.8.8 (2009-10-09 patchlevel -1) [x86\_64-linux] Probably not relevant here, but I don’t think that ruby 1.8.8 is actually out yet.
