常见的linux上的服务重启脚本

手写linux上的重启脚本，先把提纲列下

1.检查进程是否存在

存在杀死

2.备份原来的包到指定目录

3. 拉取新包，我这边为了简便，没有从jenkins slave上拿

4.启动命令

5.检查是否进程起来了

#!/bin/bash  ###path JAVA=/usr/java/jdk1.8.0_211-amd64/bin/java APP_HOME=/opt/88bugs APPNAME=TestPlatform.jar APP_PARAM="--spring.config.location=${APP_HOME}/application.properties"   ####check wheather the port is running, if yes kill it PID=`ps -ef | grep ${APP_HOME}/${APPNAME} | grep -v grep | awk '{print $2}'` echo ${PID}  if test -z ${PID} then  	echo "进程没有启动！"  else  	echo "will shutdown this process" 	kill -9 ${PID} 	sleep 2 fi   ####backuop mv ${APP_HOME}/${APPNAME} ${APP_HOME}/backup/${APPNAME}-date +%Y%m%d%H%M%S  ####deploy the war package cp -r /opt/${APPNAME}  ${APP_HOME}/${APPNAME}   ##### start the process# nohup ${JAVA} -jar ${APP_HOME}/${APPNAME} ${APP_PARAM}  > ${APP_HOME}/catalina.out 2>&1  &  afterPID=`ps -ef | grep ${APP_HOME}/${APPNAME} | grep -v grep | awk '{print $2}'` echo ${afterPID} sleep 10  if test -z ${afterPID} then 	echo "部署失败" else  	echo "部署成功" fi
