1. Project background
Assume that the IP address of the corporate DHCP server is 192.168.1.2. The domain name of the DNS server is dns.jnrp.cn, the IP address is 192.168.1.3, the WEB server address is 192.168.1.10, and the Samba server IP address is 192.168.1.5; the gateway address is 192.168.1.254; the address range is 192.168.1.3 to 192.168 .1.150, the mask is 255.255.255.0
DHCP service
-Automatically allocate addresses for a large number of clients and provide centralized management
-Reduce and manage and maintain costs, and improve network configuration efficiency
The address information that can be allocated mainly includes
-IP address and subnet mask of the network card
-Broadcast address
-Default gateway information-
DNS server address
DHCP server software
Install DHCP
[root@redhat ~]# yum install -y dhcp
Edit the dhcp main configuration file
[root@redhat ~]# vim /etc/dhcp/dhcpd.conf
Copy the file: /usr/share/doc/dhcp*/dhcpd.conf.example
after copying and opening it to see the DHCP example file:
[root@redhat ~]# cp /usr/share/doc/dhcp*/dhcpd.conf.example /etc/dhcp/dhcpd
dhcpd6.conf dhcpd.conf
[root@redhat ~]# cp /usr/share/doc/dhcp*/dhcpd.conf.example /etc/dhcp/dhcpd.conf
cp：是否覆盖"/etc/dhcp/dhcpd.conf"？ y
[root@redhat ~]# vim /etc/dhcp/dhcpd.conf
