Linux下啟動jar包的shell腳本

product-service.sh文件內容如下

#!/bin/sh
 
APP_NAME=product-service
#jar包路徑
JAR_PATH='/usr/local/app/jars'
#jar名稱
JAR_NAME=product-service-1.0.0.jar
#日志路徑
LOG_PATH='/usr/local/app/logs'
#PID  代表是PID文件
PID=$JAR_NAME\.pid
 
#使用說明，用來提示輸入參數
usage() {
    echo "Usage: sh 執行腳本.sh [start|stop|restart|status]"
    exit 1
}
 
#檢查程序是否在運行
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
}
 
#啟動方法
start(){
  is_exist
  if [ $? -eq "0" ]; then
    echo ">>> $APP_NAME is already running PID=${pid} <<<"
  else
    nohup java -Xms256m -Xmx512m -jar $JAR_PATH/$JAR_NAME >> $LOG_PATH/$APP_NAME.log 2>&1 &
    echo $! > $PID
    echo ">>> start $APP_NAME successed PID=$! <<<"
   fi
  }
 
#停止方法
stop(){
  #is_exist
  pidf=$(cat $PID)
  #echo "$pidf" 
  echo ">>> PID = $pidf begin kill $pidf <<<"
  kill $pidf
  rm -rf $PID
  sleep 2
  is_exist
  if [ $? -eq "0" ]; then
    echo ">>> PID = $pid begin kill -9 $pid  <<<"
    kill -9  $pid
    sleep 2
    echo ">>> $APP_NAME process stopped <<<" 
  else

  fi 
}
 
#輸出運行狀態
status(){
  is_exist
  if [ $? -eq "0" ]; then

}
 
#重啟
restart(){

#根據輸入參數，選擇執行對應方法，不輸入則執行使用說明
