Question

我有一个ruby程序，非常简单，只需在一堆主机上进行DNS查找。该程序从终端（Mac OS X 10.6.5），Ruby 1.9.2使用RVM运行良好。

我想按计划运行它，并希望加载LaunchDaemon来执行此操作。该程序不作为LauanchDaemon运行，并且输出文件已创建，但为空，因此我无法看到错误。我怀疑它与包含有关。

这是plist（它加载正常并尝试运行，如创建两个输出文件所证明的那样）：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

        <string>/Library/WebServer/vHosts/scripts/ping/</string>
   <key>UserName</key>
       <string>scott</string>
  </dict>
</plist>

Ruby程序是：

#!/Users/scott/.rvm/rubies/ruby-1.9.2-p0/bin/ruby
require 'rubygems'  
require 'active_record'
require 'yaml'  
require 'dnsruby'
include Dnsruby


dbconfig = YAML::load(File.open('database.yml'))
ActiveRecord::Base.establish_connection(dbconfig)

# flush cache
rslt = `dscacheutil -flushcache`

Dnsruby::DNS.open 
rslvr = Dnsruby::DNS.new

now = DateTime.now.to_s
mysqlDT = now.gsub("T", " ")
puts mysqlDT


class Host < ActiveRecord::Base  
end  
class Ip < ActiveRecord::Base  
end  

Host.find_each do |svr|
  ip = rslvr.getaddress(svr.host).to_s
  svr.lastIP = ip
  svr.save
  Ip.create(:ip => ip, :host => svr.host, :DT => mysqlDT, :hostID => svr.id)
end

根本问题是LaunchDaemon作业是从没有正确设置RVM的shell运行的，因此无法找到包含的类。由于我的系统上没有任何遗留的Ruby程序，我删除了RVM并在我的系统上的/ usr / local / bin中安装了Ruby 1.9.2，然后重新安装了宝石。

第二个问题（没有记录）是由于权限错误造成的。

Ruby prog不会作为LaunchDaemon运行
