1.dhcp服务器，是为了给网络中主机分配ip地址
2.安装dhcp服务器
1 [root@test4 named]# yum install dhcp -y
3.查找dhcp服务配置模板
1 [root@test4 named]# rpm -ql dhcp| more 2 /etc/dhcpd.conf 3 /etc/rc.d/init.d/dhcpd 4 /etc/rc.d/init.d/dhcrelay 5 /etc/sysconfig/dhcpd 6 /etc/sysconfig/dhcrelay 7 /usr/bin/omshell 8 /usr/sbin/dhcpd 9 /usr/sbin/dhcrelay 10 /usr/share/doc/dhcp-3.0.5 11 /usr/share/doc/dhcp-3.0.5/IANA-arp-parameters 12 /usr/share/doc/dhcp-3.0.5/README 13 /usr/share/doc/dhcp-3.0.5/RELNOTES 14 /usr/share/doc/dhcp-3.0.5/api+protocol 15 /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample //这是模板 16 /usr/share/doc/dhcp-3.0.5/draft-ietf-dhc-authentication-14.txt 17 /usr/share/doc/dhcp-3.0.5/draft-ietf-dhc-dhcp-dns-12.txt
4.修改配置文件
1 [root@test4 named]# cat /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample > /etc/dhcpd.conf 2 [root@test4 named]# vim /etc/dhcpd.conf 3 ddns-update-style interim; 4 ignore client-updates; 5 subnet 192.168.0.0 netmask 255.255.255.0 { //分配地址网段 6 # --- default gateway 7 option routers 192.168.0.1; //配置默认路由 8 option subnet-mask 255.255.255.0; //配置掩码 9 option nis-domain "domain.org"; 10 option domain-name "domain.org"; 11 option domain-name-servers 192.168.1.1; //配置域名服务器地址 12 option time-offset -18000; # Eastern Standard Time 13 # option ntp-servers 192.168.1.1; //配置时间服务器 14 # option netbios-name-servers 192.168.1.1; 15 # --- Selects point-to-point node (default is hybrid). Don't change this unless 16 # -- you understand Netbios very well 17 # option netbios-node-type 2; 18 range dynamic-bootp 192.168.0.128 192.168.0.254; 19 default-lease-time 21600; 20 max-lease-time 43200; 21 # we want the nameserver to appear at a fixed address 22 host ns { //根据mac地址绑定地址 23 next-server marvin.redhat.com; 24 hardware ethernet 12:34:56:78:AB:CD; 25 fixed-address 207.175.42.254; 26 } 27 }
5.配置超级作用域
1 shared-network dhcpname { 2 3 配置多个作用域 4 5 } ;
