DHCP服务器搭建及配置

DHCP服务端：

• 1、安装DHCP服务
  yum install -y dhcp*
• 2、配置DHCP
  cp /usr/share/doc/dhcp-4.2.5/dhcpd.conf.example /etc/dhcp/dhcpd.conf
  vim /etc/dhcp/dhcpd.conf

###############
option domain-name "dhcp.server";
option domain-name-servers 192.168.2.2;
default-lease-time 600;
max-lease-time 7200;
log-facility local7;

subnet 192.168.2.0 netmask 255.255.255.0 {
  range dynamic-bootp 192.168.2.100 192.168.2.110;
  option routers 192.168.2.2;
}
###############

• 3、重启DHCP
  systemctl restart dhcpd
• 4、设置开机启动
  systemctl enable dhcpd

DHCP客户端

• 1、网卡配置为DHCP
  vim /etc/sysconfig/network-scripts/ifcfg-ens33
  BOOTPROTO=“dhcp”
• 2、重启网卡
  systemctl restart network

注意事项

• 1、vmware需要将两个虚拟机都设置为桥接模式
• 2、客户端自动获取的IP，有可能不是想要的IP，原因是局域网内还有其他DHCP服务器
