一、环境

二、开机自启动jar

三、编写脚本

四、给startup.sh添加执行权限

五、编辑rc.local文件

六、授予rc.local文件权限

七、重启系统

八、重启后查看jar是否已启动

--------------------

## 一、环境 ##

系统为centos7系统

## 二、开机自启动jar ##

SearchExcel.jar

spring-boot-webservice.jar

## 三、编写脚本 ##

文件存放位置和名字自己定义，此处为startup.sh

vim startup.sh

在打开的文件中输入下面信息保存退出，注意java的安装路径必须填写

# !/bin/bash
    # program
    # file preview server start
    # 打印系统启动时的信息
    date >> /home/aaron/Desktop/launch-output.txt
    hostname >> /home/aaron/Desktop/launch-output.txt
    echo `whoami` >> /home/aaron/Desktop/launch-output.txt
    
    # java 环节配置
    export JAVA_HOME=/usr/java/jdk1.8.0_291
    export PATH=${JAVA_HOME}/bin:$PATH
    export CLASSPATH=.:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib
    export JRE=${JAVA_HOME}/jre
    
    # 启动jar服务
    nohup java -jar /home/aaron/Desktop/SearchExcel.jar > /home/aaron/Desktop/SearchExcel.log 2>&1 &
    nohup java -jar /home/aaron/Desktop/spring-boot-webservice.jar > /home/aaron/Desktop/webservice.log 2>&1 &

## 四、给startup.sh添加执行权限 ##

chmod +x startup.sh

## 五、编辑rc.local文件 ##

vim  /etc/rc.d/rc.local

在rc.local文件末尾添加startup.sh文件的路径，保存退出

#!/bin/bash
    # THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
    #
    # It is highly advisable to create own systemd services or udev rules
    # to run scripts during boot instead of using this file.
    #
    # In contrast to previous versions due to parallel execution during boot
    # this script will NOT be run after all other services.
    #
    # Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
    # that this script will be executed during boot.
    
    touch /var/lock/subsys/local
    
    /root/startup.sh

## 六、授予rc.local文件权限 ##

chmod +x /etc/rc.d/rc.local

## 七、重启系统 ##

reboot

## 八、重启后查看jar是否已启动 ##

ps  -ef |grep  java
