Linux下的DHCP配置

Posted 2020-09-16

检测是否已经按照DHCP：

rpm -q dhcp

 

 

 

安装dhcp:

yum install dhcp

 

 

centos 7 的安装方法：

vim /etc/dhcp/dhcpd.conf

 

 

ddns-update-style interim;          /*dhcp支持的dns动态更新方式*/

ignore client-updates;                     /*忽略客户端DNS动态更新*/

subnet 192.168.1.0 netmask 255.255.255.0 {/*作用域网段*/

range 192.168.1.11 192.168.1.100;      /*ip地址段范围*/

option routers 192.168.1.1;             /*网关地址*/

option subnet-mask 255.255.255.0;       /*子网掩码*/

option domain-name "koumm.com";         /*域名*/

option domain-name-servers 192.168.1.1,202.103.24.68; /*dns IP*/

option broadcast-address 192.168.16.255;/*广播地址*/

default-lease-time 86400;               /*租期1天，秒数*/

max-lease-time 172800;                  /*最长租期2天*/

 

/*绑定pc1主机ip地址配置*/

host pc1 {             

   hardware ethernet 00:a0:cc:cf:9C:14; /*绑定机MAC地址*/

   fixed-address 192.168.1.20;         /*最长租期2天*/

}

host pc2 {

   hardware ethernet 04:20:c1:f8:37:11;

   fixed-address 192.168.1.30;

}

}

超网配置文件：

 

ddns-update-style interim;      /*dhcp支持的dns动态更新方式*/

ignore client-updates;          /*忽略客户端DNS动态更新*/

shared-network mynet {          /*超网作用域选项，共同部分*/

option subnet-mask 255.255.255.0;            /*子网掩码*/

option domain-name "koumm.net";              /*域名*/

option domain-name-servers 192.168.1.2;      /*dns IP*/

option broadcast-address 192.168.1.255;      /*广播地址*/

default-lease-time 86400;                    /*租期1天，秒数*/

max-lease-time 172800;                       /*最长租期2天*/

 

 

subnet 192.168.1.0 netmask 255.255.255.0 {   /*1.0子网段*/

   range 192.168.1.11 192.168.1.100;        /*ip地址段范围*/

   option routers 192.168.1.1;               /*网关地址*/

 

   /*绑定pc1主机ip地址配置*/

host pc1 {

    hardware ethernet 00:a0:cc:cf:9C:14;

    fixed-address 192.168.1.20;

    }

   /*绑定pc2主机ip地址配置*/

host pc2 {

    hardware ethernet 04:20:c1:f8:37:11;

    fixed-address 192.168.1.30;

}

}

subnet 192.168.2.0 netmask 255.255.255.0 {    /*2.0子网段*/

   range 192.168.2.10 192.168.2.100;         /*ip地址段范围*/

   option routers 192.168.2.1;                /*网关地址*/

        }

subnet 192.168.3.0 netmask 255.255.255.0 {    /*3.0子网段*/

   range 192.168.3.10 192.168.3.100;         /*ip地址段范围*/

   option routers 192.168.3.1;                /*网关地址*/

}

}
