springboot项目设置开机自启

1.编写脚本ServiceStart.sh【该脚本对存放对目录没有要求，比如我是存在/opt目录下的】
执行命令： vim ServiceStart.sh

# !/bin/bash
# program
# test java open

export JAVA_HOME=/opt/java/jdk1.8.0_231
export JRE=${JAVA_HOME}/jre
export CLASSPATH=$JAVA_HOME/lib:$JRE/lib:.
export PATH=$PATH:$JAVA_HOME/bin/:$JRE/bin
nohup java -jar /opt/project/aa.jar >/opt/project/log/aa.log &

2.将脚本添加到/etc/rc.local【若没有改文件，则手动创建即可】

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
  
bash /opt/ServiceStart.sh
exit 0

3.修改/etc/rc.local权限

chmod +x /etc/rc.local

4.重新启动【重启服务之前，确保该服务没有人在使用】

reboot

5.重启后查看服务是否正常启动
比如：

1)查看Jar运行的信息
ps -ef|grep /opt/project/aa.jar
2)查看端口状态
netstat -nltp|grep port

说明：
我的系统是ubunt18，此文档对centos系统也同样适用。
