一键重启Linux系统下的java web项目和java应用程序的shell脚本

这几天做项目迁移，需要将之前在Win下面的java web项目和java应用程序迁移到Linux系统下面去，迁移的原因就不多说了，无非是linux系统安全，稳定，也不为怪，毕竟是做舆情的，信息也挺重要的哈！

在开始前想给大家推荐个好玩的桌游，名字叫做UNO,额？不知道啥意思，找度娘去吧，我每天打开百度的次数不下玉五百次的，作为程序员经常和大家玩这个的，每次都要笑出病了，嘻嘻！

正题：

在下面的脚本中写了两个java web项目，其实是两个tomcat啦，第三个是java应用，对于web项目在使用时只要修改前面的三个变量就行了：TOMCAT_PATH,TOMCAT_BIN,TOMCAT_PORT,对应着tomcat的所在路径，所在的bin目录，还有就是项目的端口号。

对于java项目只需修改：APP_PATH,APP_HOME,APP_MAINCLASS就行，一看就明白，不多说。直接

上shell代码（ps:代码很详细的喽）：
