一  开机自启动

1.1 jar包

1.2 编写启动shell脚本

编写脚本 ziqidong.sh,内容如下:

#!/bin/bash


export JAVA_HOME=/usr/local/java/jdk1.8.0_171
export JRE_HOME=/usr/local/java/jdk1.8.0_171/jre
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HONE/lib/
:$CLASSPATH
export PATH=$JAVA_HOME/bin/:$PATH


cd /root/export/


nohup java -jar test-jar.jar  >  /root/export/ljf.out 2>&1 &

1.3 设置开机启动

1.修改配置文件   /etc/rc.local  

在文件最后追加：

/root/export/ziqidong.sh

#!/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
/etc/init.d/keepalived start
/root/export/ziqidong.sh
~                           

2.设置文件授权

 chmod +x /root/export/ziqidong.sh
  chmod +x /etc/rc.local 

3.检测脚本是否正常

bash   /etc/rc.local

4.开启重新

reboot

1.4 开机测试

通过命令查看

  netstat -ntlp | grep 8082 （查看端口）
  ps aux|grep java（查看服务）
