####### 安装使用原理 本脚本实现自动安装################
#  apt-get install vnstat
#  ip addr 查看网卡名称是否是 eth0，如果是网卡名是 ens3 或者 venet0
#  编辑/etc/vnstat.conf 替换，重启vnstat服务(本脚本自动能自动修改网卡名)
#  sed -i "s/eth0/ens3/g"   /etc/vnstat.conf
#  systemctl restart vnstat

#  crontab -e   修改定时任务, 添加运行脚本

#  # netlog.sh  定时执行转html脚本，每3小时一次，为了修改方便和多台机器用，直接到github更新
