sudo yum update
Mount USB
列出所有存储设备
lsblk
找到U盘大小的分区（例如根据大小来判断）。注意是分区而不是盘，例如sda1是分区，而sda盘
挂载U盘
lsblk
mkdir /mnt/usb/
mount -t vfat /dev/sdb1 /mnt/usb/
cd /mnt/usb/
这样U盘就成功mount上去了。这里sdb1是我的U盘，根据实际情况写就行。
卸载U盘
umount /mnt/usb/
设置ADSL的PPPOE拨号上网
以下操作都以root用户执行
像上面一样设置号eth0并启动
1. 安装pppoe拨号软件
下载所需软件rp-pppoe、ppp、libpcap
rpm -ivh libpcap-1.0.0-6.20091201git117cb5.el6.x86_64.rpm
rpm -ivh ppp-2.4.5-5.el6.x86_64.rpm
rpm -ivh rp-pppoe-3.10-8.el6.x86_64.rpm
2. 拨号上网
软件安装在/usr/sbin下面
cd /usr/sbin/
ls
pppoe-setup为配置pppoe-status为查看状态，adsl-start或者ifup ppp0启用连接，adsl-stop或者ifdown ppp0断开连接，
pppoe-setup
adsl-start
如果需要手动配置，可以
vi /etc/sysconfig/network-scripts/ifcfg-ppp0
ping百度可以的话就成功了。有时会拨号不成功，不一定是配置有问题。多试几次，重启一下。我曾经试过拨号不成功，只有ppp0有ipv4地址，eth0没有ipv4地址。过了半天和若干次重启之后正常了，ppp0和eth0都有ipv4地址。
