Configure the DHCP server and dhcp server
I. Installation
Yum install dhcpd-y
Ii. Configuration
[Root @ server03/] # rpm-qc dhcp
The dhcp configuration file is displayed.
[Root @ server03/] # vim/etc/dhcp/dhcpd. conf
Change configuration file
Option domain-name "example.com"; # specifies the domain name, indicating the domain of the DHCP server;
Default-lease-time 600;
Max-lease-time 7200; # lease period, 600 7200 is the default time, if not written, the effect is the same
Log-facility local7; # log
Subnet 192.168.4.0 netmask 255.255.255.0 {# specify the network segment
Range 192.168.4.130 192.168.4.132; # address range
}
Save and exit
Restart the hdcp service and set another virtual machine as a bridge to restart the network. You can obtain the IP address 192.168.4.131 allocated by dhcp.
On the dhcp server,
Run tail-f/var/log/messages to view dynamic log files and dhcp request messages.
Open the configuration file:
[Root @ server03/] # vim/etc/dhcp/dhcpd. conf
Add
Option routers 192.168.4.254; # Gateway
Option domain-name-servers 192.168.4.103; # dns Server
Restart the dhcpd client and restart the network to obtain the address of the gateway and dns server.
[Root @ localhost Desktop] # vim/etc/resolv. conf
You can see:
# Generated by NetworkManager
Domain example.com
Search example.com
Nameserver 192.168.4.103
Address binding:
Open the configuration file:
[Root @ server03/] # vim/etc/dhcp/dhcpd. conf
Add:
Host fantasia {
Hardware ethernet 00: 0C: 29: 60: 31: B7
Fixed-address 192.168.4.133 # The address should be out of the address pool above to prevent conflict
}
Restart the DHCP Client and restart the network. Check the ip address. The ip address is changed to the binding address just set.
OK!
How to configure a dhcp server
For Windows systems, do the following:
Choose "start"> "Control Panel"> "add or delete program"> "network service" (you can double-click or click Details)> "Dynamic Host Configuration Protocol .. Then wait for the installation. After the installation is complete, you can see DHCP in the management tool !!
For a Linux system, follow these steps:
1. Attach the disc first # mount/dev/cdrom/media
2. then install the DHCP Server Installation Package # rpm-ivh/media/Server/dhcp-3.0.5-3.el5.i386.rpm
3. Copy the configuration sample file of the dhcp server to/etc and change it to dhcpd. conf.
# Cd/usr/share/doc/dhcp-3.0.5/
# Cp dhcpd. conf. sample/etc/dhcpd. conf this step will show whether to overwrite or not, just write y.
4. modify the configuration file of the dhcp server: # vim/etc/dhcpd. conf
In this step, I cannot insert an image. I will explain the following points to modify:
(1) option routers IP Address
Purpose: Specify the default gateway for the client.
(2) option subnet-mask subnet mask
Purpose: set the subnet mask of the client.
(3) option domain-name-servers IP Address
Purpose: Specify the DNS server address for the client.
5. Start the dhcp server: # service dhcpd restart
If possible, perform the following steps:
# Iptables-F clear firewall rules
Now, go to the client to automatically obtain the IP address !!
If you are a fool routing, you can start the DHCP service and there is nothing to do with it.
If you still do not understand, please contact me, I will give you information... QQ--651750543
Please add some points. It took a lot of effort !! Thank you !!
