centos6.4 erecting DHCP

The actual environment does not have to specifically set up DHCP services, usually through the switch or router to do DHCP. However, using CentOS as a DHCP is actually very simple, and at night do a DHCP entertainment. Refer to the article "Bird Brother's private food", Thank you brother Bird.

1. First, we check whether DHCP is already installed, the command is as follows: RPM -QA |GREP DHCP2. If not installed, install with Yum (Local source Erection reference previous), command as follows: Yum install  dhcp 3. Install DHCP, set/etc/dhcp/dhcpd.conf, command as follows:vim /etc/dhcp/dhcpd.conf     ddns-update-style    none;       Do not update ddns     ignore client-updates;           Ignore terminal DNS updates      default-lease-time    259200;    Default Lease Time      max-lease-time    518400;         Maximum lease time     option routers    192.168.1.254;     Default Gateway, Please pay attention to this address.     option domain-name   am.centos;         freely write the domain name     optons domain-name-servers    192.168.1.1   dns Address             subnet 192.168.1.0 netmask  255.255.255.0{        range 192.168.1.100 192.168.1.200         }    after the above settings are complete, a simple DHCP is set up, below we start.   4. Start DHCP.    before we start DHCP, we notice that we first change the address of our CentOS eth0 or eth1    command as follows:   ifconfig  eth0  192.168.1.254 255.255.255.0   Please note this address.    then start with the command as follows:   service dhcpd start  5. Check if the service starts OK, the command is as follows:   Service dhcpd status  netstat -tnlup |grep dhcp  6. View the startup log under the following command:   cat /var/log/messages |grep dhcp    7. End.
