Linux DHCP配置的完美攻略(1)(2)

Linux DHCP配置 单网配置文件

编辑dhcp配置文件为以下内容。具体的实际的环境的配置可以在以下配置文件的基础上进行修改，使其满足具体环境中的应用。

vi /etc/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;
}
}

Linux DHCP配置 超网配置文件

vi /etc/dhcp.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*/
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*/
}
}
