上面的jar_auto.sh脚本如下：

#!/bin/bash#配置jdk的路径
export JAVA_HOME=/usr/java/jdk1.8.0_341-amd64   #此处为我的java环境路径，需要改为自己的JDK路径
export JRE_HOME=${JAVA_HOME}/jre

export PATH=${JAVA_HOME}/bin:$PATH#有时需要把jar包延时启动（比如博主不设置延时启动jar，nacos会提示拒绝连接）
#延时30S运行jar包，需要延时启动则放开sleep注释行 （sleep+数字，表示延迟多少秒启动）
#sleep 30   #有点奇怪，设置了延时有一个jar包起不来，此处延时仅供参考
