After the installation is complete Linux system can look ip: ifconfig command.
Newly installed Linux systems only an IP loopback address 127.0.0.1, no specific ip address value
As the windows have
IP address, subnet mask, default gateway, dns. These can be automatically acquired, under Linux we have to configure these address values
Configure the IP address
Enter the directory: cd / etc / sysconfig / network-scripts /
We show you what directory: ls below these documents
Locate the first file ifcfg-eth0 file default card
Use Linux editor vi ifcfg-eth0
DEVICE = eth0 refers to the equipment we use
It means a physical HWADDR's MAC address
UUID is an identifier can be removed
Are onboot boot, change yes
bootproto into static
Modification can click a, began to modify the contents section
See your Virtual Network Editor, look at how much your own network
Not the same for everyone, find no conflict of values 3-254 LAN. 0,1,2 and 255 are occupied, all these values do not configure
Delete the UUID and MAC address
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.9.22
NETMASK=255.255.255.0
GATEWAY=192.168.9.2
DNS1 = 114114114114
dns2 can not configure
chestnut:
Press Esc. : Wq Save the file to
After saving, enter the directory /etc/udev/rules.d/
Command: cd /etc/udev/rules.d/
ls view the file, there are four files
Where the 70-persistent-net.rules this document is to MAC binding file, just delete the MAC address, so I have to delete this file out
Delete files: rm -fr /etc/udev/rules.d/70-persistent-net.rules
Restart the virtual machine: init 6 or shutdown: poweroff
After the restart continue to log in to view the ip
One more ip address, you can ping the external network test, network configuration is complete so that amount.
Supplementary Snapshot
Operation here can take a snapshot.
Take a snapshot point
给快照取一个名字，这里我起名字叫basic。当我们重新恢复时候还可以用此快照
快照也可以做为一个镜像，之后再安装的时候可以直接使用镜像
栗子：
打开刚才拍摄快照，点击克隆
下一步
我这里就选择了连接克隆，这个占用磁盘比较少而已。
更改虚拟机名字，就可以完成创建虚拟机。比安装快捷很多。
进入克隆的Linux中更改ip地址，和刚才是一样套路
更改完，删除70-persistent-net.rules文件：init 6重启即可
完毕。
