How to set up Linux-DHCP Server
This article introduces you how to set up a Linux-DHCP server, the content is very detailed, interested friends can refer to, hope to be helpful to you.
DHCP server:
Function: provide dynamic ip to every host in the LAN
Mode of communication:
Client: use 255.255.255.255 to broadcast the same DHCP client to send DCHP Discover packets.
DHCP: after receiving the packet data, send back a DHCP offer packet with the IP,MASK,NETWORK, gateway, etc., which DHCP gives to the client, as well as the lease date.
Client: after receiving the message, send a DHCP request packet for confirmation.
DHCP: after receiving the message, reconfirm it.
Install DHCP:
Yum search dhcpd
Yum install dhcpd
View the installed files:
Rpm-ql dhcpd
Edit / etc/dhcp/dhcpd.conf file
7 option domain-name "localhost"; set the domain name of this machine
8 option domain-name-servers 192.168.29.0,192.168.29.100; set DNS server IP
nine
10 default-lease-time 600; default lease time
11 max-lease-time 7200; maximum lease time in seconds
23 log-facility local7
28 subnet 192.168.29.0 netmask 255.255.255.0 {
29}
32 subnet NETWOEK NETMASK Subnet Mask
33 subnet 192.168.29.0 netmask 255.255.255.0 {
34 range 192.168.29.100 192.168.29.150; assign ip range
35 option routers 192.168.29.2; Gateway
38}
"host assigns ip to fixed hosts"
65 host RedHatserver {host "character creation"
66 hardware ethernet 00VOCVERV 29VOV 4BRO BRV 1BRU 6A; "assign MAC of the host"
67 fixed-address 192.168.29.250; ip
68 option routers 192.168.29.3; Gateway
69 option domain-name "you"; domain name
70 option domain-name-servers 114.114.114.1148.8.8; DNS server address
71}
The configuration file takes effect from local to global.
Default-lease-time 600
Max-lease-time 7200; it can also be set for a particular host
Client:
Configuration / etc/sysconfig/network-script/ifcfg-eth0 file
Put BOOTPROTO=dhcp in it
If the virtual machine is configured as a DHCP server, the appeal settings are the same, but:
And make sure
The client needs to set up the figure as above.
The server starts the DHCP service:
Service dhcpd start
Or / etc/rc.d/init.d/dhcpd start
Dynamic ip can be obtained when the client is booted normally.
