Unicorn cannot find satellite using capistrano

It seems I cannot connect to Unicorn when deploying. I use capistrano for deployment.

Looking at the unicorn log during deployment, I get the following errors:

/home/deployer/apps/my-app/releases/20130417145122) I, [2013-04-17T14:53:04.982369 #6565] INFO -- : forked child re-executing... /home/deployer/.rvm/gems/ ruby-1.9.3-p392@global /gems/bundler-1.3.5/lib/bundler/definition.rb:16:in `build': /home/deployer/apps/my-app/releases/20130417020329/Gemfile not found (Bundler::GemfileNotFound) from /home/deployer/.rvm/gems/ ruby-1.9.3-p392@global /gems/bundler-1.3.5/lib/bundler.rb:148:in `definition' from /home/deployer/.rvm/gems/ ruby-1.9.3-p392@global /gems/bundler-1.3.5/lib/bundler.rb:116:in `setup' from /home/deployer/.rvm/gems/ ruby-1.9.3-p392@global /gems/bundler-1.3.5/lib/bundler/setup.rb:17:in `<top (required)>' from /home/deployer/.rvm/rubies/ruby-1.9.3-p392/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require' from /home/deployer/.rvm/rubies/ruby-1.9.3-p392/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require' E, [2013-04-17T14:53:05.054942 #18166] ERROR -- : reaped #<Process::Status: pid 6565 exit 1> exec()-ed

Capistrano cleans up the last 5 releases of the application, and I see that the coherent is trying to access a non-existent (last deleted) version.

I found this code, which I put in unicorn.rb.erb, but that didn’t help (I tried to hardcode it too): http://davidvollbracht.com/blog/headachenewunicorn-capistrano-bundler-usr2

 before_exec do |server| ENV['BUNDLE_GEMFILE'] = "<%= current_path %>/Gemfile" end

After deploying my code, I started and stopped NGINX, and started and stopped the unicorn, but I have the same problem.

My initial stack overflow message is here, but I thought it was due to a resource pipeline: The conveyor is not working in the rail processing environment

Thoughts?

Here is my unicorn.rb.erb file:

 working_directory "<%= current_path %>" pid "<%= unicorn_pid %>" stderr_path "<%= unicorn_log %>" stdout_path "<%= unicorn_log %>" listen "/tmp/unicorn.<%= application %>.sock" worker_processes <%= unicorn_workers %> timeout 30 preload_app true before_exec do |server| ENV['BUNDLE_GEMFILE'] = "<%= current_path %>/Gemfile" end before_fork do |server, worker| # Disconnect since the database connection will not carry over if defined? ActiveRecord::Base ActiveRecord::Base.connection.disconnect! end # Quit the old unicorn process old_pid = "#{server.config[:pid]}.oldbin" if File.exists?(old_pid) && server.pid != old_pid begin Process.kill("QUIT", File.read(old_pid).to_i) rescue Errno::ENOENT, Errno::ESRCH # someone else did our job for us end end end after_fork do |server, worker| # Start up the database connection again in the worker if defined?(ActiveRecord::Base) ActiveRecord::Base.establish_connection end end

Here is my unicorn_init.sh file:

 #!/bin/sh ### BEGIN INIT INFO # Provides: unicorn # Required-Start: $remote_fs $syslog # Required-Stop: $remote_fs $syslog # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Manage unicorn server # Description: Start, stop, restart unicorn server for a specific application. ### END INIT INFO set -e # Feel free to change any of the following variables for your app: TIMEOUT=${TIMEOUT-60} APP_ROOT=/home/deployer/apps/my-app/current PID=$APP_ROOT/tmp/pids/unicorn.pid CMD="cd $APP_ROOT; bundle exec unicorn -D -c $APP_ROOT/config/unicorn.rb -E production" AS_USER=deployer set -u OLD_PIN="$PID.oldbin" sig () { test -s "$PID" && kill -$1 `cat $PID` } oldsig () { test -s $OLD_PIN && kill -$1 `cat $OLD_PIN` } run () { if [ "$(id -un)" = "$AS_USER" ]; then eval $1 else su -c "$1" - $AS_USER fi } case "$1" in start) sig 0 && echo >&2 "Already running" && exit 0 run "$CMD" ;; stop) sig QUIT && exit 0 echo >&2 "Not running" ;; force-stop) sig TERM && exit 0 echo >&2 "Not running" ;; restart|reload) sig USR2 && echo reloaded OK && exit 0 echo >&2 "Couldn't reload, starting '$CMD' instead" run "$CMD" ;; upgrade) if sig USR2 && sleep 2 && sig 0 && oldsig QUIT then n=$TIMEOUT while test -s $OLD_PIN && test $n -ge 0 do printf '.' && sleep 1 && n=$(( $n - 1 )) done echo if test $n -lt 0 && test -s $OLD_PIN then echo >&2 "$OLD_PIN still exists after $TIMEOUT seconds" exit 1 fi exit 0 fi echo >&2 "Couldn't upgrade, starting '$CMD' instead" run "$CMD" ;; reopen-logs) sig USR1 ;; *) echo >&2 "Usage: $0 <start|stop|restart|upgrade|force-stop|reopen-logs>" exit 1 ;; esac

You should use the package installation task for Capistrano if you have not already done so: https://github.com/carlhuda/bundler/blob/master/lib/bundler/capistrano.rb

Gem dependencies are automatically installed in the / home / deployer / apps / my -app / shared / bundle directory during deployment and saved in versions.

I had a similar problem when using the before_fork block to set BUNDLE_GEMFILE didn't actually solve the problem, even though the Rails application thinks that ENV ['BUNDLE_GEMFILE'] points to the Gemfile through the current / symbolic link.

I still do not quite understand this, but we also used RVM. I managed to fix the problem by adding:

 export BUNDLE_GEMFILE="${APP_ROOT}/Gemfile"

in the init script. Does your problem solve?
