游戏程序守护进程-Windows版，是用VBS写的，适用于Windows 2003 x86 和 Windows 2003 x64.

    游戏程序的开启一般是需要按照指定的顺序开启的，这里以标准的db-gs-gg的架构为例，正常的开启顺序为db-gs-gg，如果gg程序挂了，一般我们手动的判断流程是先判断db程序是否正常，然后判断gs程序是否正常，都没有问题，然后再开启gg程序，该脚本就是按照该关联关系判断的原则进行处理的。

    所有的配置信息存放在setting.ini

    ‘说明

    ‘name项配置服务或程序名称,设置为设置为任务管理器中的image name

    ‘type项配置需要守护的进程为s（service）或是p（program）

    ‘process项配置程序的绝对路径或服务名称，如果守护进程和程序放在同一目录可配置相对路径

    ‘relate项配置是（y）否（n）有关联程序

    ‘logfile项配置log存放路径，默认deamon.log，存放守护进程目录

    [setting]

    name=EMeditor.exe

    type=S

    process=zhudongfangyu

    relate=y

    logfile=

    ‘relate_ip项配置关联程序/服务的ip，本机可配置localhost

    ‘relate_port项配置关联程序/服务的端口号，目前只支持tcp端口

    [relate]

    relate_ip=192.168.30.109

    relate_port=139

    如果配置了关联关系，即relate=y，则会程序开启前会自动判断关联程序是否正常，需使用check_tcp，是一个第三方判断tcp端口的程序，将check_tcp.zip中的check_tcp.exe放在setting.ini同一目录中即可。

    守护进程主程序源代码如下：

    其中的wscript.sleep 的值可以根据实际情况自定义修改，需要注意的是要合理设置该值，如果该值设置的过小会是判断过于频繁，导致守护进程占用服务器系统资源。另外如果关联程序不在同一台服务器上，需考虑网络延时等因素，否则有一定概率因网络原因造成无法正常探测关联程序，从而导致程序无法正常开启。
