通用spring boot jar包，服務重啓停腳本分享

需根據實際狀況設置JAVA_HOME、APP_HOME
腳本使用方式：bash restart.sh {start|stop|restart|status|info}
vi restart.sh

#!/bin/bash
source /etc/profile
JAVA_HOME=/usr/local/jdk1.8.0_152
# application directory
cd `dirname $0`

JAR_HOME=`${APP_HOME} |awk -F"/" '{print $NF}'`
# Java JVM lunch parameters
if [ x"$JVMSIZE" == x ];then
  JVMSIZE="-Xms1G -Xmx1G -Djava.security.egd=file:/dev/./urandom"
