ruby 实现windows service启动和关闭 nginx和jruby trinidad
require "win32/service"include Win32class String; def to_dos() self.tr('/','\\') end endclass String; def from_dos() self.tr('\\','/') end end#override to support utf8class String; def strip() self end endrubyexe="C:/bin/ruby.exe".to_dosSERVICE_FILE= (File.expand_path(File.dirname(File.dirname(__FILE__)))+ '/service.rb').to_dosSERVICE_NAME="Test Service"if ARGV[0] case ARGV[0] when "install" Service.new( :service_name => SERVICE_NAME, :service_type => Service::WIN32_OWN_PROCESS, :start_type => Service::AUTO_START, :error_control => Service::ERROR_NORMAL, :binary_path_name => "#{rubyexe} #{SERVICE_FILE}", :description => 'Run nginx, jruby all in one' ) when "uninstall" Service.delete(SERVICE_NAME) endend
?注意：为何重载String.strip
原因在于中文版windows在安装服务过程中调用get_last_error会返回utf-8的字符，此时win32-service gem的error.rb会报invalidate byte sequence的错误。
原因是对字符串进行了strip
如果不进行strip则没有任何问题。

服务部分的代码如下：
#service.rbrequire 'win32/daemon'include Win32SERVICE_LOG = File.expand_path(File.dirname(File.dirname(__FILE__)))+ '/services.log'JR_PATH = 'c:\jruby-1.7.0\bin'JR_LOG = File.expand_path(File.dirname(File.dirname(__FILE__)))+ '/jruby.log'class Daemon def service_main while running? if @pid.nil? @pid = Process.spawn('c:\nginx-1.2.1\nginx.exe', chdir: 'c:\nginx-1.2.1', out: SERVICE_LOG, err: :out) Process.detach @pid if @pid_jruby.nil? @pid_jruby = [] start_jruby end Process.waitpid(@pid) else sleep(3) end end end def service_stop if @pid pid_kill = Process.spawn('c:\nginx-1.2.1\nginx.exe -s stop', chdir: 'c:\nginx-1.2.1', out: SERVICE_LOG, err: :out) Process.waitpid(pid_kill) end if @pid_jruby.size > 0 @pid_jruby.each do |pid| pid_kill = Process.kill(9, pid) end end end def start_jruby if @pid_jruby.empty? [3000, 4000].each do |port| cmd = "#{JR_PATH}\\jruby.exe -S trinidad -e production -p #{port}" pid = Process.spawn(cmd, chdir: 'C:\app\', out:JR_LOG, err: :out) @pid_jruby << pid Process.detach pid end end endendDaemon.mainloop?结果：
以上代码在ruby 1.9.3 win7 上通过
如在win7上报安装权限不足，请使用administrator 启动cmd console。
代码尚有refactory的空间，时间仓促，敬请谅解。
