f = Forking.new(:name => 'test', :working_dir => File.dirname(__FILE__),
:log_file => "spawner.log", :pid_file => "spawner.pid", :sync_log => true)
f.before_fork do
puts "load env"
end
f.after_fork do
puts "restart connects"
end
2.times do |i|
f.spawn(:name => "test1", :log_file => "test1.log") do
loop do
puts "test1 #{i}"
sleep 1
end
end
end
3.times do |i|
f.spawn(:log_file => "test2.log", :sync_log => true) do
exec 'ruby', '2.rb', '--test'
end
end
f.run!Usage:
$ ./1.rb start
