Linux中进行DHCP的配置

以下红色区域是自己要修改的成自己的DHCP获取的地址范围

[root@OracleOnLinux root]# cp /usr/share/doc/dhcp-3.0pl1/dhcpd.conf.sample /etc/dhcpd.conf [root@OracleOnLinux root]# vi /etc/dhcpd.conf 1 ddns-update-style interim;2 ignore client-updates;3 4 subnet 192.168.0.0 netmask 255.255.255.0 {----“注：192.168.0.0是你给DHCP提供地址池的IP，而255.255.255.0是子网掩码”

# option domain-name “mylinux.org”;----“域名，在windows环境下很有用，比如你的客户端是在那一个域，这里就要改成客户端所在的域名。没有域名的话可以在option domain-name的前面加#号”

option domain-name-servers 192.168.0.154,61.139.2.69;-----“192.168.0.154，61.139.2.69是你的DHCP客户端获取的DNS”

1、设置为自动获取IP2、手动租借：ipconfig /release 和 ipconfig /renew ====================== 查看地址的租借情况：
