新手入门之Redhat EL4+DHCP
http://enjoy48.cublog.cn 1、查看环境
#rpm -qa|grep dhcp
得知系统默认没有安装dhcp服务端 2.安装程序:
插入光盘2
#mount /dev/cdrom
#cd /media/cdrom/RedHat/RPMS
#rpm -ivh dhcp-3.0.1-12_EL.i386.rpm 4、查看DHCP安装位置
#rpm -qpl dhcp-3.0.1-12_EL.i386.rpm 5、配置
#cp /usr/share/doc/dhcp-3.0.1/dhcpd.conf.sample /etc/dhcpd.conf
#vi /etc/dhcpd.conf
具体语法可查看：
#man dhcpd.conf
因没有DNS服务器，故涉及DNS地方均注销了，最后配置文件如下：
ddns-update-style none;
ignore client-updates; subnet 192.168.1.0 netmask 255.255.255.0 { # --- default gateway
        option routers                  192.168.1.1;
        option subnet-mask              255.255.255.0; #       option nis-domain               "domain.org";
#       option domain-name              "domain.org";
        option domain-name-servers      192.168.1.1;         option time-offset              -18000; # Eastern Standard Time
#       option ntp-servers              192.168.1.1;
#       option netbios-name-servers     192.168.1.1;
# --- Selects point-to-point node (default is hybrid). Don't change this unless
# -- you understand Netbios very well
#       option netbios-node-type 2;         range dynamic-bootp 192.168.1.1 192.168.1.254;
        default-lease-time 21600;
        max-lease-time 43200;
default-lease-time 21600;
        max-lease-time 43200;         # we want the nameserver to appear at a fixed address
#       host ns {
#               next-server marvin.redhat.com;
#               hardware ethernet 12:34:56:78:AB:CD;
#               fixed-address 207.175.42.254;
#       }
}
配置完毕后可运行下面命令测试语法：
#service dhcpd configtest 6、运行
#service dhcpd start
此时客户端即可获取IP地址。
注意，其IP分配顺序是从大到小，即从254开始分配，然后253、252……
