刚接到开发人员要求，今晚上线新的ChatterServer版本，新版本目录存在一些变化，要求我出一个新的服务控制脚本，因此在前两版的基础上有了第三版，前两版地址《运维经验分享（一）-- Linux Shell之ChatterServer服务控制脚本》和《运维经验分享（二）-- Linux Shell之ChatterServer服务控制脚本二次优化》
增加softlink invoke和今天改良的shell脚本中的一些好的方法和技巧，今天改良的shell脚本请参考文章《运维经验分享（五）-- 改进的java进程管理的服务控制脚本》。
有几个已知的问题：
-
BASENAME因为时间原因使用了绝对路径，后期将更新新版
-
log日志的某些处理上有些多余，将于后期更新新版
其他问题欢迎各位网友、博友批评指正和留言！
现将脚本内容粘贴如下：
