spingboot jar 包启动遇到得坑

先摘抄一篇文章

pringboot打成jar包后,可直接用java -jar app.jar 启动,或者使用 nohup java -jar app.jar & 后台启动,也可以将 jar包链接到/etc/init.d/下,作为服务启动 ,这两种启动方式各有缺点,可以用一个shell脚本解决这个问题

将文章最后脚本保存为sh文件,比如 spring-boot.sh
,跟jar包放在同一目录下,给与执行权限 chomd 777 spring-boot.sh.使用方法如下:

切换到jar目录,执行:

sh spring-boot.sh start app.jar --spring.profiles.active=peer1

解释:
第一个参数: 启动命令 (start,stop,restart,status)
第二个参数: 需启动的jar包
第三个参数: 启动参数(可不加)

脚本中的jvm参数可以根据需求修改

#!/bin/bash

SpringBoot=$2

#启动参数
START_OPTS=$3

#JVM参数
JVM_OPTS="-Dname=$SpringBoot  -Duser.timezone=Asia/Shanghai -Xms512M -Xmx512M -XX:PermSize=256M -XX:MaxPermSize=512M -XX:+HeapDumpOnOutOfMemoryError -XX:+PrintGCDateStamps  -XX:+PrintGCDetails -XX:NewRatio=1 -XX:SurvivorRatio=30 -XX:+UseParallelGC -XX:+UseParallelOldGC"

    exit 1

if [ "$SpringBoot" = "" ];
then
    echo -e "\033[0;31m 未输入应用名 \033[0m"
    exit 1

function start()
{
    count=`ps -ef |grep java|grep $SpringBoot|grep -v grep|wc -l`
    if [ $count != 0 ];then
        echo "$SpringBoot is running..."
    else
        echo "Start $SpringBoot success..."
        nohup java -jar  $JVM_OPTS $SpringBoot  $START_OPTS > /dev/null 2>&1 &
    fi
}

function stop()
{
    echo "Stop $SpringBoot"
    boot_id=`ps -ef |grep java|grep $SpringBoot|grep -v grep|awk '{print $2}'`
    count=`ps -ef |grep java|grep $SpringBoot|grep -v grep|wc -l`

    if [ $count != 0 ];then
        kill $boot_id
        count=`ps -ef |grep java|grep $SpringBoot|grep -v grep|wc -l`

        boot_id=`ps -ef |grep java|grep $SpringBoot|grep -v grep|awk '{print $2}'`
        kill -9 $boot_id
    fi
}

function restart()
{
    stop
    sleep 2
    start
}

function status()

    count=`ps -ef |grep java|grep $SpringBoot|grep -v grep|wc -l`
    if [ $count != 0 ];then

 其中出现得错误如下  1. 启动命令需要更改 nohup java -jar $springboot > /dev/null 2>&1 &
2. 赋予权限问题 命为 chmod   并非本文中得 chomd
