DHCP server configuration

DHCP installation 11: First install dhcp-3.0.5-18.el5 package 2: After installation and then through rpm -qc dhcp view his configurable document 3: find /etc/dhcpd. Conf this document and edit 4: edit vim /etc/dhcpd.conf with vim editor and see that this text is empty, but you can see a comment (# see /usr/share/doc/dhcp*/Dhcpd.conf.sample ) Probably means: reference /usr/share/doc/dhcp*/dhcpd.conf.sample5: refer to the /usr/share/doc/dhcp*/dhcpd.conf.sample file in the previous step, in vim Execute in etc/dhcpd.conf: r /usr/share/doc/dhcp*/dhcpd.conf.sample Read the contents of this document 6: Modify the current /etc/dhcpd.conf file 1 # 2 # DHCP Server Configuration File. 3 # see /usr/share/doc/dhcp*/dhcpd.conf.sample 4 # 5 ddns-update-style interim; 6 ignore client-updates; 7 option domain-name-servers 222.88.88.88,222.85.85.85 ; (Super-scoped DNS server) 8 subnet 192.168. 60.0 netmask 255.255.255.0 { (a common scope network segment, subnet mask) 9 10 # --- default gateway 11 option routers 192.168.60.254; (gateway) 12 option subnet-mask 255.255.255.0; (subnet Mask) 13 14 option nis-domain "domain.org"; 15 option domain-name "test"; (name of the scope) 16 filename "pxelinux.0"; 17 option time-offset -18000; # Eastern Standard Time 18 # option ntp-servers 192.168.1.1; 19 # option netbios-name-servers 192.168.1.1; 20 # --- Selects point-to-point node (default is hybrid).

However, you need to add a command to add a line after the 7th line, shared-network AAA (the name of the super scope) { & rdquo;, then the last line Write another line “}”, finally wq save and exit.
