- #!/usr/bin/env bash
- ####### 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10分钟一次，为了修改方便和多台机器用，直接到github更新
- # */10 * * * * wget -qO- git.io/fxxlb | bash
