springboot jar包 jenkins自动化部署脚本

springboot项目在使用jenkins自动化部署过程中，需要用到自动化部署脚本：

#!/bin/bash
#需要部署的appName 不带后缀
WEB_APP_NAME=app-platform-service-boot-1.0.0-SNAPSHOT
#app项目路径
BASE_PATH=/usr/local/app/ushow-app
JAR_NAME=${BASE_PATH}/${WEB_APP_NAME}.jar
PID=${BASE_PATH}/${WEB_APP_NAME}.pid
#运行环境 对应profile的值  dev/test/prod
ENVIRONMENT=dev
#日志文件路径
LOG_PATH=${BASE_PATH}/logs/app.log
#使用说明，用来提示输入参数
usage() {
echo "Usage: sh 执行脚本.sh [start|stop|restart|status]"
exit 1
}
#检查程序是否在运行
is_exist(){
pid=`ps -ef|grep ${JAR_NAME}|grep -v grep|awk '{print $2}'`
#如果不存在返回1，存在返回0
if [ -z "${pid}" ]; then
return 1
else
return 0
fi
}

#启动方法
start(){
is_exist
if [ $? -eq "0" ]; then
echo ">>> ${JAR_NAME} is already running PID=${pid} <<<"
else
#`source /etc/profile`
source /etc/profile; nohup java -server -Xms256m -Xmx256m -XX:MaxNewSize=64m -jar ${JAR_NAME} --spring.profiles.active=${ENVIRONMENT} >>${LOG_PATH} 2>&1 &
echo $! > ${PID}
echo ">>> start ${JAR_NAME} successed PID=$! <<<"
fi
}
#停止方法
stop(){
pid_file=$(cat ${PID})
if [ -z ${pid_file} ];then
echo ">>> ${JAR_NAME} pid file is not exist <<<"
else
echo ">>> ${JAR_NAME} PID = ${pid_file} begin kill ${pid_file} <<<"
kill ${pid_file}
rm -rf ${PID}
sleep 2
fi
is_exist
if [ $? -eq "0" ]; then
echo ">>> ${JAR_NAME} exist PID = ${pid} begin kill -9 ${pid} <<<"
kill -9 ${pid}
sleep 2
echo ">>> ${JAR_NAME} process stopped <<<"
else
echo ">>> ${JAR_NAME} is not running <<<"
fi
}
#输出运行状态
status(){
is_exist
if [ $? -eq "0" ]; then
echo ">>> ${JAR_NAME} is running PID is ${pid} <<<"
else
echo ">>> ${JAR_NAME} is not running <<<"
fi
}
#重启
restart(){
stop
start
}

#根据输入参数，选择执行对应方法，不输入则执行使用说明
case "$1" in
"start")
start
;;
"stop")
stop
;;
"status")
status
;;
"restart")
restart
;;
*)
usage
;;
esac
exit 0

当需要在机器上同时部署N个项目时，上述脚本需要先创建目录，并且复制脚本。不够友好

优化版本(自动创建目录，多个不同项目可共用同一脚本)：

#!/bin/sh

PROJECT_NAME=$2
WEB_APP_NAME=${PROJECT_NAME}-platform-service-boot-1.0.0-SNAPSHOT
BASE_PATH=/usr/local/app/ushow-${PROJECT_NAME}
JAR_NAME=${BASE_PATH}/${WEB_APP_NAME}.jar
PID=${BASE_PATH}/${WEB_APP_NAME}.pid
LOG_PATH=${BASE_PATH}/logs/${PROJECT_NAME}.log

#参数判断
#echo "输入参数：$0 $1 $2"

if [ ! -n "$2" ] ;then
 echo "请输入项目名projectName"
fi

if [ ! -d ${BASE_PATH}/logs  ];then
  echo "初始化项目路径: ${BASE_PATH}/logs"
  `mkdir -p ${BASE_PATH}/logs`
fi

#使用说明，用来提示输入参数
usage() {
echo "Usage: sh $1 [start|stop|restart|status]"
exit 1
}
#检查程序是否在运行
is_exist(){
pid=`ps -ef|grep ${JAR_NAME}|grep -v grep|awk '{print $2}'`
#如果不存在返回1，存在返回0
if [ -z "${pid}" ]; then
return 1
else
return 0
fi
}

#启动方法
start(){
is_exist
if [ $? -eq "0" ]; then
echo ">>> ${JAR_NAME} is already running PID=${pid} <<<"
else
nohup java -server -Xms128m -Xmx128m -XX:MaxNewSize=32m -jar ${JAR_NAME} --spring.profiles.active=dev >>${LOG_PATH} 2>&1 &
echo $! > ${PID}
echo ">>> start ${JAR_NAME} successed PID=$! <<<"
fi
}
#停止方法
stop(){
pid_file=$(cat ${PID})
if [ -z ${pid_file} ];then
echo ">>> ${JAR_NAME} pid file is not exist <<<"
else
echo ">>> ${JAR_NAME} PID = ${pid_file} begin kill ${pid_file} <<<"
kill ${pid_file}
rm -rf ${PID}
sleep 2
fi
is_exist
if [ $? -eq "0" ]; then
echo ">>> ${JAR_NAME} exist PID = ${pid} begin kill -9 ${pid} <<<"
kill -9 ${pid}
sleep 2
echo ">>> ${JAR_NAME} process stopped <<<"
else
echo ">>> ${JAR_NAME} is not running <<<"
fi
}
#输出运行状态
status(){
is_exist
if [ $? -eq "0" ]; then
echo ">>> ${JAR_NAME} is running PID is ${pid} <<<"
