添加重启后执行任务  
crontab -e  
加入  
@reboot nohup sh /root/scripts/[init.sh][] &

编辑init.sh内容

#!/bin/bash
    #导入jre必须手动导入 不然启动不了（巨坑）
    export JAVA_HOME=/app/jdk1.8.0_211
    export JRE_HOME=${JAVA_HOME}/jre
    export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
    export PATH=${JAVA_HOME}/bin:$PATH
    
    echo 'init...'
    systemctl stop firewalld.service
    sleep 5
    nohup sh /root/scripts/startup.sh &
    sleep 5
    nohup sh /root/scripts/startupApollo.sh>>/root/scripts/apollo.log & 
    echo 'init success'

startup.init控制mysql和主主模式配置并监控mysql服务
