Linux基础命令-虚拟机搭建-静态IP设置
虚拟机：VM12
系统：CentOS-6.8-x86_64-minimal.iso
下载：CentOS-6.8-x86_64-minimal.iso
Xshell6：编程环境
下载：Xshell6
虚拟机安装系统
新建虚拟机：
输入账号：root （回车键）
密码：就是刚刚你设置的密码（回车键）
查看IP：
命令 ：ifconfig
[root@localhost Desktop]# ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:65536 Metric:1

RX bytes:960 (960.0 b) TX bytes:960 (960.0 b)
配置静态IP地址(请照着顺序往下输入命令配置，如何快速复制内容，命令到虚拟机内的Linux里面呢？)选中要复制的内容选中虚拟机，但是鼠标别点进去，ctrl+v就可以粘帖进去了，下面的命令直接可以复制进去，编辑的内容也可以这样复制进去，原理就不解释了，很简单。祝你学习愉快！
输入命令：vi /etc/sysconfig/network-scripts/ifcfg-eth0
在末尾加入下面信息:
BOOTPROTO="static"#将dhcp改为static
ONBOOT="yes"#将no改为yes
IPADDR=192.168.117.3#静态ip地址
NETMASK=255.255.255.0#子网掩码
GATEWAY=192.168.117.2#网关
DNS1=192.168.117.2#DNS
输入命令： vi /etc/resolv.conf
添加下列内容：
domain localdomain
search localdomain
nameserver 192.168.117.2
输入命令：route add default gw 192.168.117.1
输入命令：vi /etc/sysconfig/network-scripts/route-eth0
添加内容：192.168.117.0/24 via 192.168.117.2
输入命令：service network restart
输入命令：ifconfig
输入命令：ping -c4 www.baidu.com
虚拟机克隆
在VMware里克隆出来的CentOS Linux。。
ifconfig没有看到网卡eth0.，然后重启网卡报错误解决办法：
service network restart
Shutting down loopback insterface: [ OK ]
Bringing up loopback insterface: [ OK ]
Bringing up interface eth0: Device eth0 does not seem to be present,delaying initialization. [FAILED]
vi /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.

# You can modify it, as long as you keep each rule on a single

# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:8f:89:9
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:50:bd:1
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
ATTR{address}=="00:0c:29:50:bd:17 NAME=“eth1”
记住eth1的MAC地址：
vi /etc/sysconfig/network-scripts/ifcfg-eth0
将 DEVICE="eth0"改成 DEVICE="eth1"
将 HWADDR="00:0c:29:8f:89:97"改成上面的mac地址 HWADDR="00:0c:29:50:bd:17"
重启网路一切正常：
service network restart
Xshell6配置
