我正在使用BluePill來管理進程,例如Rails的延遲作業。在BluePill日誌,我得到這個消息:使用進程管理器啓動延遲作業時丟失PID文件
W, [2010-09-27T01:23:20.447053 #19441] WARN -- : [fsg_distro:delayed_job] pid_file /srv/fsg_distro/shared/pids/delayed_job.pid does not exist or cannot be read
W, [2010-09-27T01:23:20.447368 #19441] WARN -- : [fsg_distro:delayed_job] Executing start command: ruby script/delayed_job -e production start
I, [2010-09-27T01:23:20.469165 #19441] INFO -- : [fsg_distro:delayed_job] Going from down => starting
因此它聲稱一個pid文件丟失,這是,但不應是PID被創建時BluePill啓動延時工作過程?
更新 要更清楚地瞭解此錯誤,我可以手動成功運行該命令,但Bluepill無法運行啓動命令。當我手動運行它,它看起來像這樣:
[email protected]:/srv/fsg_distro/current$ /usr/bin/env RAILS_ENV=production /usr/bin/ruby /srv/fsg_distro/current/script/delayed_job start
delayed_job: process with pid 17564 started.
當我與Bluepill運行它,它看起來是這樣的:

我的藥丸是這樣的:
APP_ROOT='/srv/fsg_distro'
RAILS_ROOT='/srv/fsg_distro/current'
RAILS_ENV='production'
RUBY_EXEC='/usr/bin/ruby'
Bluepill.application("fsg_distro", :log_file => "/srv/fsg_distro/shared/log/bluepill.log") do |app|
app.process("delayed_job") do |process|
process.working_dir = RAILS_ROOT
process.start_grace_time = 30.seconds
process.stop_grace_time = 30.seconds
process.restart_grace_time = 30.seconds
process.start_command = "/usr/bin/env RAILS_ENV=#{RAILS_ENV} #{RUBY_EXEC} #{RAILS_ROOT}/script/delayed_job start"
process.stop_command = "/usr/bin/env RAILS_ENV=#{RAILS_ENV} #{RUBY_EXEC} #{RAILS_ROOT}/script/delayed_job stop"
process.pid_file = "#{APP_ROOT}/shared/pids/delayed_job.pid"
process.uid = "deploy"
process.gid = "deploy"
end
end
而且我的延遲作業腳本如下所示:
#!/usr/bin/env ruby
ENV['RAILS_ENV'] ||= 'production'
require File.dirname(__FILE__) + '/../config/environment'
require 'delayed/command'
Delayed::Command.new(ARGV).daemonize
2個問題看到如何仍未得到答覆。你需要什麼權限才能寫入文件夾/ srv/fsg_distro/shared/pids /,並且用戶導軌(來自機器george?)是否擁有這些權限? – Hugo 2010-10-06 14:17:10
Bluepill和我登錄的用戶是同一個用戶....只要用戶是所有者或組中的用戶,他就可以寫入pids目錄 – Tony 2010-10-08 01:01:21
