用 capistrano 启动 delayed_job 任务的时候，无法起作用，可能和 ssh 登陆的 交互模式有关。网上搜了下，有说 执行 run 的方法中加 :pty => true 的。我试了 都没有作用。
task :restart_delayed_job do
＃原来是想通过执行文件来重新启动的，没有效果
# run("cd #{release_path} && chmod +x script/restart_delayed_job", :pty => true)
# run("cd #{release_path} && ./script/restart_delayed_job", :pty => true)
＃ 用了 pty 也没用
run("cd #{release_path} ; nohup rake jobs:work > log/delayed_job.log 2>&1 &", :pty => true)
end
你们的这种部署是怎么写的呢？
@yorzi 这个够全，不过作者没把 script/delayed_job 脚本放上去。 找了一个 ruby 的脚本，用 daemon_spawn 做后台任务的。和 ruby-china 的启动 resque 一样。
#!/usr/bin/env ruby
# -*- ruby -*-
require 'rubygems'
require 'daemon_spawn'
RAILS_ROOT = File.expand_path(File.join(File.dirname(__FILE__), '..'))
class DelayedJobWorker < DaemonSpawn::Base
def start(args)
ENV['RAILS_ENV'] ||= args.first || 'development'
Dir.chdir RAILS_ROOT
require File.join('config', 'environment')
Delayed::Worker.new.start
end
def stop
system("kill `cat #{RAILS_ROOT}/tmp/pids/delayed_job.pid`")
end
end
DelayedJobWorker.spawn!(:log_file => File.join(RAILS_ROOT, "log", "delayed_job.log"),
:pid_file => File.join(RAILS_ROOT, 'tmp', 'pids', 'delayed_job.pid'),
:sync_log => true,
:working_dir => RAILS_ROOT)
