Improved version of Java program restart, and with ansible yml batch execution

The original Lsof-i:port way to restart the Java program is often minor problems, where new scripts are improved and used in conjunction with Ansilbe, directly on scripts and samples.

1. restat-tm.sh

#!/bin/bash

Java_home= "/usr/local/java/jdk1.8.0_25" # # #jdk

App_mainclass= "TM" # # #TM. jar

App_home= "/home/java/tm" ####/home/java/tm/***

#java虚拟机启动参数
