我想运行ruby mongrel脚本作为我的配置系统(CHEF)的最后一步。因此,我写了一个upstart .conf文件,其中包含以下条目:
#!upstart
description "mongrel server"
author "daniele"
start on startup
stop on shutdown
# Automatically restart process if crashed
respawn
# Essentially lets upstart know the process will detach itself to the background
expect fork
# Run before process
pre-start script
end script
# Start the process
script
cd /vagrant/trunk
/bin/sh /vagrant/trunk/script/server -p 3000 >> /home/vagrant/log.txt
end script
然而,log.txt文件为空并运行netstat -an | grep 3000什么都没显示。我认为该脚本不可执行,但运行chmod并没有改变任何内容。
但是,如果我手动执行脚本,我可以启动服务器
vagrant@ubuntu10:/vagrant/trunk$ ./script/server
=> Booting Mongrel
=> Rails 2.3.4 application starting on http://0.0.0.0:3000
/usr/local/rvm/gems/ruby-1.8.7-p352/gems/rails-2.3.4/lib/rails/gem_dependency.rb:119:Warning:Gem::Dependency#version_requirements is deprecated and will be removed on or after August 2010. Use #requirement
=> Call with -d to detach
=> Ctrl-C to shutdown server
脚本的内容是:
#!/usr/bin/env ruby
require File.dirname(__FILE__) + '/../config/boot'
require 'commands/server'
我使用RVM和Ruby 1.8.7,Rubygems 1.3.7运行Vagrant。引导配方是:
[...]
template "mongrel.upstart.conf" do
path "/etc/init/mongrel.conf"
source "mongrel.upstart.conf.erb"
mode 0644
owner "root"
group "root"
end
service "mongrel" do
provider Chef::Provider::Service::Upstart
supports :restart => true, :start => true, :stop => true
action [:enable, :start]
end
有什么想法吗? 感谢

问题是您的Upstart配置在Vagrant完成设置您安装代码的共享文件夹之前运行。当您从命令行手动运行它后,它已经被挂载。
我不确定解决方案是什么 - 如果你可以在启动过程中挂钩,你可以发出一个事件,例如:
initctl emit vagrant-mounted
您的Upstart配置可以等待
start on vagrant-mounted

我通过添加
解决了类似的问题sleep 10
到脚本。像这样:
...
# Start the process
script
sleep 10
cd /vagrant/trunk
/bin/sh /vagrant/trunk/script/server -p 3000 >> /home/vagrant/log.txt
end script
....

至少在Ubuntu 12.04中,您可以等待mountall作业发出的“已安装”信号。
start on mounted
上面的节应该适用于Vagrant共享文件夹。
