DHCP的搭建
系统 环境：
[[email protected] ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
[[email protected] ~]# uname -r
3.10.0-327.el7.x86_64
[[email protected] ~]# ip addr show enp0s8 | awk 'NR==3{print $2}'
192.168.235.36/24
[[email protected] ~]# yum install -y dhcp
[[email protected] ~]# cp -a /usr/share/doc/dhcp-4.2.5/dhcpd.conf.example /etc/dhcp/dhcpd.conf
[[email protected] ~]# cat /etc/dhcp/dhcpd.conf
subnet 192.168.235.0 netmask 255.255.255.0 {
range 192.168.235.10 192.168.235.20;
default-lease-time 600;
max-lease-time 7200;
}
#可以看到我们的配置非常少，此处主要演示是 安装服务 更多配置在 man 5 dhcpd.conf
[[email protected] ~]# systemctl start dhcpd
[[email protected] ~]# setenforce 0
[[email protected] ~]# systemctl stop firewalld
另开启一台虚拟机windows server 2003 与 DHCP服务器在同一个VM里面
可以看到 windows server 2003 可以获取到 IP地址
[[email protected] ~]# cat /var/lib/dhcpd/dhcpd.leases
# The format of this file is documented in the dhcpd.leases(5) manual page.
# This lease file was written by isc-dhcp-4.2.5
