jar包启动脚本, 以及外置配置文件application.yml

想使用sh脚本来启动,停止,重启我们的jar服务, 顺便还要外置配置文件方便修改
示例server.sh如下,启动命令为sh server.sh start或restart或stop,修改其中的这几个参数即可:
SPB_OPTS 使用的配置profile类型
APP_LOCATION jar在linux中的绝对路径
APP_NAME 项目名称

#!/bin/bash
VM_OPTS="-Xms2048m -Xmx2048m"
SPB_OPTS="--spring.profiles.active=prod"
APP_LOCATION="/home/pmish/apps/m2k/m2k.jar"
APP_NAME="m2k"
PID_CMD="ps -ef |grep $APP_NAME |grep -v grep |awk '{print \$2}'"

start() {
 echo "=============================start=============================="
 PID=$(eval $PID_CMD)
 if [[ -n $PID ]]; then
    echo "$APP_NAME is already running,PID is $PID"
 else
    java $VM_OPTS -jar $APP_LOCATION $SPB_OPTS >/dev/null &
    echo "java $VM_OPTS -jar $APP_LOCATION $SPB_OPTS >/dev/null "
    PID=$(eval $PID_CMD)
    if [[ -n $PID ]]; then
       echo "Start $APP_NAME successfully,PID is $PID"
    else
       echo "Failed to start $APP_NAME !!!"
    fi
 fi
 echo "=============================start=============================="
}

stop() {
 echo "=============================stop=============================="
 PID=$(eval $PID_CMD)
 if [[ -n $PID ]]; then
    kill -15 $PID
    sleep 5
    PID=$(eval $PID_CMD)
    if [[ -n $PID ]]; then
      echo "Stop $APP_NAME failed by kill -15 $PID,begin to kill -9 $PID"
      kill -9 $PID
      sleep 2
      echo "Stop $APP_NAME successfully by kill -9 $PID"
    else
      echo "Stop $APP_NAME successfully by kill -15 $PID"
    fi
 else
    echo "$APP_NAME is not running!!!"
 fi
 echo "=============================stop=============================="
}

restart() {
  echo "=============================restart=============================="
  stop
  start
  echo "=============================restart=============================="
}

status() {
  echo "=============================status=============================="
  PID=$(eval $PID_CMD)
  if [[ -n $PID ]]; then
       echo "$APP_NAME is running,PID is $PID"
  else
       echo "$APP_NAME is not running!!!"
  fi
  echo "=============================status=============================="
}

info() {
  echo "=============================info=============================="
  echo "APP_LOCATION: $APP_LOCATION"
  echo "APP_NAME: $APP_NAME"
  echo "VM_OPTS: $VM_OPTS"
  echo "SPB_OPTS: $SPB_OPTS"
  echo "=============================info=============================="
}

help() {
   echo "start: start server"
   echo "stop: shutdown server"
   echo "restart: restart server"
   echo "status: display status of server"
   echo "info: display info of server"
   echo "help: help info"
}

case $1 in
start)
    start
    ;;
stop)
    stop
    ;;
restart)
    restart
    ;;
status)
    status
    ;;
info)
    info
    ;;
help)
    help
    ;;
*)
    help
    ;;
esac
exit $?

如果希望application.yml外置, 则应该在jar包同级目录新建一个config文件夹, 将application.yml放在config目录下即可
