DHCP服务部署

========================================================================================

搭建dhcp服务器步骤

1.准备工作

=====准备lan1网段的隔离环境

=====关闭SELinux和防火墙

=====setenforce 0

=====getenforce

=====vim /etc/sysconfig/selinux

=====systemctl stop firewalld.service

=====systemctl disable firewalld.service

========================================================================================

2.配置本地yum源

=====mkdir /etc/yum.repos.d/default

=====mv /etc/yum.repos.d/CentOS-* /etc/yum.repos.d/default

=====vim /etc/yum.repos.d/local.repo

=====vim---[local]

=====vim---name=localsrc

=====vim---baseurl=file:///mnt

=====vim---enabled=1

=====vim---gpgcheck=0

=====mount /dev/cdrom /mnt/

=====yum clean all

=====yum makecache

========================================================================================

3.安装dhcp工作软件

=====yum install -y dhcp

========================================================================================

4.修改本地网卡

=====vim /etc/sysconfig/network-scripts/ifcfg-eth0

=====# Generated by dracut initrd

=====vim---NAME=eth0

=====vim---ONBOOT=yes

=====vim---BOOTPROTO=none

=====vim---TYPE=Ethernet

=====vim---IPADDR=192.168.87.101

=====vim---NETMASK=255.255.255.0

=====systemctl restart network

=====systemctl restart NetworkManager

========================================================================================

5.编辑dhcp配置文件

=====vim /etc/dhcp/dhcpd.conf

subnet 192.168.87.0 netmask 255.255.255.0 {

range 192.168.87.10 192.168.87.100;

option routers 192.168.87.254;

option domain-name-servers 114.114.114.114, 8.8.8.8;

}

========================================================================================

6.启动dhcp服务

=====systemctl start dhcpd

=====systemctl enable dhcpd

=====ss -anup | grep :67

========================================================================================
