基于linux下的虚拟机里 dhcp安装、动态网络编辑、及其ip的获取
1、hostnamectl 查看是哪个系统
2、建立iso 镜像目录
mkdir /iso/
3、复制镜像文件到iso目录下
scp [email protected]:/home/kiosk/Desktop/rheL-server-7.0* /iso
4、建立source7.0
mkdir /source7.0
5、挂载镜像文件到source7.0
mount /iso/rhe*7.0 /source7.0
6、编辑文件
vim /etc/yum.repos.d/yum.repo
编辑文件的内容如下
[source7.0]
name=source7.0
baseurl=file:///source7.0
gpgcheck=0
7、安装dhcp
yum search dhcp 查询dhcp
yum install dhcp.x86_64 -y 安装dhcp,-y的意思是安装时不需要提醒是否是否需要安装
8、切换到/etc/dhcp目录下
cd /etc/dhcp
9、复制文件到/etc/dhcp/dhcpd.conf下
cp /usr/share/doc/dhcp*/dhcpd.conf.example /etc/dhcp/dhcpd.conf
10、查看/etc/dhcp下有什么文件
ls 有三个文件
11、编辑文件
vim /etc/dhcp/dhcpd.conf
编辑文件
将文件的第7行和第8行进行修改为
7 option domain-name "example.com";
8 option domain-name-servers 114.114.114.114;
并删除27行
并将32 -35行修改为
32 subnet 172.25.254.0 netmask 255.255.255.0 {
33 range 172.25.254.100 172.25.254.110; #ip的范围
34 option routers 172.25.254.250;
35 }
将后面的删除
12、cat /var/lib/dhcpd/dhcpd.leases #查看获得的ip从哪里来的
