linux jar包启动脚本

#!/bin/bash#java env#shell脚本有时候调用linux的环境变量会有问题，所以这里还是把用到的java环境再设置一下export JAVA_HOME=/usr/local/jdk1.7#app name 为了确保脚本通用APP_NAME=lagou-serviceSERVICE_DIR=/home/lagou/$APP_NAMESERVICE_NAME=lagou-serviceAPP_JAR=$SERVICE_NAME\.jar#启动app的时候，将进程的pid保存在这里，方便以后杀死进程用APP_PID=$SERVICE_NAME\.pidcd $SERVICE_DIRcase "$1" in     start)        #/dev/null 就不会有nohup.out文件了。        nohup $JAVA_HOME/bin/java -Xms32m -Xmx128m -jar $APP_JAR >/dev/null 2>&1 &        #将pid写入文件        echo $! > $SERVICE_DIR/$APP_PID        echo "===== start $SERVICE_NAME"        ;;    stop)        kill `cat $APP_PID`        #删除掉pid文件        rm -f $SERVICE_DIR/$APP_PID        #查看是不是杀死进程了        sleep 5                #获得进程号，复制号两边不能留空格                pid=`ps -ef | grep -w $SERVICE_NAME | grep -v grep | awk '{print $2}'`        #判断相等两边要留空格        if ["$pid" == ""];then            echo "=== kill successfully "        else            echo "===== kill fail and try to kill -9"            echo "====  the pid is  $pid"            kill -9 $pid        fi        echo "stop finished"        ;;    *)        echo "please use start or stop 参数"        ;;esacexit 0
