- 查看客户端的IP地址
- 查看Windows客户端IP地址
服务端查看DHCP的日志文件

实验环境说明


	主机系统	系统版本	获取IP地址方式	IP地址
服务端	Linux	RHEL 7.0	静态IP	192.168.43.128/24
客户端	Linux	RHEL 7.4	DHCP分配固定IP	192.168.43.15/24
客户端	Windows	Windows 11	DHCP自动随机分配	x.x.x.x

注意事项

在使用两台Linux主机时，一定要保证两台设备之间可以互相连通，可以先配置静态IP，测试两台主机之间是否是连通的
虚拟网络编辑器中，不要使用使用本地DHCP服务将IP地址分配给虚拟机
两台设备都是使用仅主机模式，或者使用相同的VMnet接口

请添加图片描述

服务器配置

配置服务器的IP地址

为服务器配置IP地址，并重启网卡，使配置生效

[root@Server ~]# vim /etc/sysconfig/network-scripts/ifcfg-eno16777736 
[root@Server ~]# cat /etc/sysconfig/network-scripts/ifcfg-eno16777736 
TYPE=Ethernet
BOOTPROTO=static
NAME=eno16777736
DEVICE=eno16777736
ONBOOT=yes
IPADDR=192.168.43.128
NETMASK=255.255.255.0
GATEWAY=192.168.43.1
DNS1=8.8.8.8
[root@Server ~]# systemctl restart network

分配的IP地址必须和配置的静态IP地址在同一个网段

这里的ifcfg-ens33为我的网卡名，不同版本的系统，网卡名会存在差异，具体的根据自己的网卡名进行配置，NAME、DEVICE与网卡名都要保持一致

配置本地YUM仓库

首先需要使用RHEL的ISO镜像，并连接到连接虚拟机
将镜像文件进行挂载

[root@Server ~]# mount /dev/cdrom /mnt/
mount: /dev/sr0 写保护，将以只读方式挂载
[root@Server ~]#

配置YUM仓库，使用本地的ISO镜像文件进行安装。如果虚拟机已经连接网络，也可以使用网络源进行软件包的安装

[root@Server ~]# cd /etc/yum.repos.d/
[root@Server yum.repos.d]# rm -rf * //删除此目录下的所有其他源配置
[root@Server yum.repos.d]# vim rhel.repo //配置新的源文件
[root@Server yum.repos.d]# ls
rhel.repo
[root@Server yum.repos.d]# cat rhel.repo 
[Base]
name=RHEL                //仓库名
baseurl=file:///mnt      //使用的仓库源，file://为固定格式，/mnt表示本地软件包所在的目录
gpgcheck=0               //是否进行检查验证
enabled=1                //是否启用本仓库

如果/etc/yum.repos.d/目录下还有其他的.repo文件，则使用rm -rf *全部删除。避免使用了其他的源文件。

清除软件包缓存

[root@Server yum.repos.d]# yum clean all 
已加载插件：langpacks, product-id, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
正在清理软件源： Base

[root@Server yum.repos.d]#

重新加载软件包

[root@Server yum.repos.d]# yum repolist all 
已加载插件：langpacks, product-id, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Base                                            | 4.1 kB     00:00

repolist: 4,986
[root@Server yum.repos.d]#

repolist：4,986：表示有可用的软件包数量，如果没有，则检查本地源文件的配置。

安装DHCP软件包

使用YUM工具安装DHCP软件包

[root@Server ~]# yum -y install dhcp
Loaded plugins: langpacks, product-id, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

[root@Server ~]#

复制DHCP的默认配置文件到DHCP的配置目录中

[root@Server ~]# cd /etc/dhcp/
[root@Server dhcp]# ls
dhclient.d  dhclient-exit-hooks.d  dhcpd6.conf  dhcpd.conf  scripts
[root@Server dhcp]# cat dhcpd.conf 
#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.example
# see dhcpd.conf(5) man page
#
[root@Server dhcp]# cat /usr/share/doc/dhcp-4.2.5/dhcpd.conf.example | grep -v "#" >> dhcpd.conf
[root@Server dhcp]# ls
dhclient.d  dhclient-exit-hooks.d  dhcpd6.conf  dhcpd.conf  scripts
[root@Server dhcp]#

/usr/share/doc/dhcp-4.2.5/dhcpd.conf.example：为DHCP的默认配置文件，根据不同的DHCP软件包的版本不同，需要修改/usr/share/doc/下的DHCP版本

grep -v "#" >> dhcpd.conf：表示将默认配置文件中的注释行删除，然后重新追加到dhcpd.conf文件中

修改DHCP的配置文件，根据需求进行相关的配置

[root@Server dhcp]# vim dhcpd.conf
[root@Server dhcp]# cat dhcpd.conf
#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.example
# see dhcpd.conf(5) man page
#
subnet 192.168.43.0  netmask 255.255.255.0 { 
        //配置DHCP服务器可以分配的地址网段以及子网掩码
  range 192.168.43.20 192.168.43.40;             //配置DHCP服务器可以分配的地址范围
  option domain-name-servers 192.168.43.128;     //配置DNS服务器的IP地址
  option routers 192.168.43.1;                   //配置默认网关
  default-lease-time 600;                        //配置默认租期，单位是秒
  max-lease-time 7200;                           //配置最大租期，单位是秒
}

host RHEL_Client_7.4 { 
                              //为特殊的主机单独配置
  hardware ethernet 00:0c:29:9e:9b:29;           //需要绑定固定IP的主机MAC地址
  fixed-address 192.168.43.15;                   //为主机绑定固定IP地址
}

对于配置文件的修改，尽量不在源文件上进行修改，先进行复制，将源内容进行注释，做好备份，以免配置错误无法回滚。

如果不需要对特殊的主机分配固定的IP地址，则不需要配置host

配置防火墙和SELinux

防火墙放行DHCP服务

[root@Server ~]# systemctl status firewalld.service 
firewalld.service - firewalld - dynamic firewall daemon

SELINUX=disabled 
SELINUXTYPE=targeted 
[root@Server ~]#

!$：表示上一条命令的最后一个参数

grep -v "#" | grep -v "^$"：表示过滤注释行和空行

启动DHCP服务

启动DHCP服务

[root@Server ~]# systemctl restart dhcpd.service //重新启动DHCP服务

客户端配置

将客户端的IP地址获取方式修改为通过DHCP动态获取，并重新启动网卡

[root@Client ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens33 
[root@Client ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens33 
TYPE=Ethernet
BOOTPROTO=dhcp             //配置为通过DHCP获取IP地址
NAME=ens33
DEVICE=ens33
ONBOOT=yes                 //配置开机自启动

# 配置静态IP地址
#IPADDR=192.168.43.131
#NETMASK=255.255.255.0
#GATEWAY=192.168.43.254
#DNS1=8.8.8.8
[root@Client ~]# systemctl restart network

查看客户端的IP地址

使用ifconfig或者ip a查看本机的IP地址

ether 00:0c:29:9e:9b:29：表示本机网卡的MAC地址，在服务器配置主机与IP绑定时，则需要查看本机网卡的MAC地址

可以看到本机的IP地址为192.168.43.15，即为DHCP服务器分配的IP地址

查看Windows客户端IP地址

配置Windows客户端的VMnet 1网卡的IP地址获取方式为DHCP
查看IP地址信息

服务端查看DHCP的日志文件

在服务端查看DHCP的日志文件，查看具体的地址分配信息
