初学Linux

Linux学习迈出了第一步，在VirtualBox CentOS最小系统中解决了虚拟网卡配置问题，成功连上互联网，并对yum进行了配置，增加了网易的镜像源，通过yum成功安装了gcc和vim。
目前采用NAT（网络地址转换）方式联接Internet，后续尝试采用其他三种方式。
解决问题的关键点：
Fixing the No Such Device eth0 on Centos (VirtualBox)
• Run ifconfig -a and then you will see ethX come up, which has a MAC address in it.
• Go to /etc/sysconfig/network-scripts/ifcfg-eth0 and changed the MAC address on the eth0 to the MAC that was attached to ethX in the ifconfig.
• Remove the file /etc/udev/rules.d/70-persistent-net.rules
• Reboot the machine
