虚拟机linux建立dhcp服务器

---

一、linux安装dhcp服务器步骤安装DHCP包
[root@miner-k~]#yum-yinstalldhcp
[root@miner-k~]#rpm-qldhcp.x86_64
/etc/dhcp
/etc/dhcp/#DHCP配置文件
/etc/dhcp/
.....
/usr/sbin/dhcpd#DHCP服务器端主流程
/usr/sbin/dhcrelay#DHCP中继服务器进程
/var/lib/dh​​cpd/#DHCP租约记录
修改配置文件
optiondomain-name"";#在/etc/中搜索后指定参数
optiondomain-name-servers114.114.115.115,114.114.114.114;#DNS服务器地址
subnet10.254.239.0netmask255.255.255.224{
optionrouters204.254.239.1;#指定网关
range10.254.239.1010.254.239.20;#指定DHCP地址池。Linux按照从大到小的顺序分配IP地址。，windows中分配是从小到大
,;
}
#通过MACaddress指定IP对应的主机。地址
DHCP对应端口
服务器UDP67
客户端UDP68
实例部署DHCP服务器
修改配置文件
[root@miner-k~]#vim/etc/dhcp/
subnet192.168.100.0netmask255.255.255.0{
range192.168.100.200192.168.100.210;
optiondomain-name-servers114.114.114.114,114.114.115.115;
optiondomain-name"";
optionrouters192.168.100.1;
default-lease-time600;
max-lease-time7200;
}
启动DHCP服务器
[root@miner-k~]#servicedhcpdrestart
启动dhcpd：[确定]
检查DHCP监听端口
[root@矿工-k~]#netstat-anlp|grep67
udp000.0.0.0:670.0.0.0:*4841/dhcpd
