huikau?

So I needed to have a quick way to start/stop/restart/tail -f logs for two different Apache Tomcat instances, Rake is a great tool for this.

I wrote the following very quickly, sure there may be other “frameworks” out there to do this, but I didn’t download anything, just wrote it and off I go. (no xml, sorry Ant)

# home directory for all this stuff
HOME = '/path/to/my/tomcats'
# defining our servers and their locations
SERVERS = {
  :one => "#{HOME}/tomcat_one/",
  :two => "#{HOME}/tomcat_two/"
}

# sure there is a better way than this.?.?.
task :default do
  puts "\nThe following are the tasks you may choose from:\n"
  app = Rake.application
  app.do_option('--tasks', ARGV.shift)
  app.display_tasks_and_comments()
end

SERVERS.each do |name, dir|
  namespace "#{name}" do
    desc "start the #{name} server instance"
    task :start do
      Dir.chdir(dir)
      puts `./bin/startup.sh`
    end

    desc "stop the #{name} server instance"
    task :stop do
      Dir.chdir(dir)
      puts `./bin/shutdown.sh`
    end

    desc "tail the #{name} server log"
    task :tail do
      system("tail -f #{dir}/logs/catalina.out")
    end
  end
end

def server_names
  SERVERS.keys.join(', ')
end

[:start, :stop].each do |action|
  desc "#{action} servers (#{server_names()})"
  task "#{action}" do
    SERVERS.keys.each do |key|
      task("#{key}:#{action}").invoke
    end
  end
end

desc "restart servers (#{server_names()})"
task :restart do
  task(:stop).invoke
  task(:start).invoke
end
