Centos6.5-install DHCPServer,

Centos6.5-install DHCPServer,

1. Check whether dhcp has been installed.

[Zfp @ localhost ~] $ Rpm-q dhcp
Package dhcp is not installed
[Zfp @ localhost ~] $

2. query dhcp-related rpm packages in the yum network source.

[Root @ localhost zfp] # yum list | grep dhcp
Dhcp. x86_64. 1.1-53. P1.el6. centos.1 updates
Dhcp-common.x86_64. 1.1-53. P1.el6. centos.1 updates
Dhcp-devel.i686. 1.1-53. P1.el6. centos.1 updates
Dhcp-devel.x86_64. 1.1-53. P1.el6. centos.1 updates
Sblim-cmpi-dhcp.i686 1.0-1. el6 base
Sblim-cmpi-dhcp.x86_64 1.0-1. el6 base
Sblim-cmpi-dhcp-devel.i686 1.0-1. el6 base
Sblim-cmpi-dhcp-devel.x86_64 1.0-1. el6 base
Sblim-cmpi-dhcp-test.x86_64 1.0-1. el6 base

3. Install dhcp

[Root @ localhost zfp] #Yum install dhcp-y

4. Check whether the installation is successful.

[Root @ localhost zfp] # rpm-q dhcp
Dhcp-4.1.1-53.P1.el6.centos.1.x86_64
[Root @ localhost zfp] #

Query the installed rpm package containing the dhcp string package name
[Root @ localhost zfp] # rpm-qa | grep dhcp
Dhcp-common-4.1.1-53.P1.el6.centos.1.x86_64
Dhcp-4.1.1-53.P1.el6.centos.1.x86_64

5. modify the configuration file/etc/dhcp/dhcpd. conf.

Different releases may not be the/etc/dhcp/dhcpd. conf file, or the/etc/dhcpd. conf file. The centos6.5 release version is/etc/dhcp/dhcpd. conf.

[Root @ localhost zfp] #Vim/etc/dhcp/dhcpd. conf

Ddns-update-style interim; # indicates the dynamic information update mode of the dhcp server and dns Server

Ignore client-updates; # ignore client updates

Subnet 192.168.145.0 netmask 255.255.255.0 {# indicates that the IP address I allocated is in the CIDR Block 192.168.145.0 and the subnet mask is 255.255.255.0.

Range 192.168.145.200 192.168.145.210; # The range of rented IP addresses

Option domain-name-servers 8.8.8.8;

Option domain-name "example.org ";

Option routers 192.168.145.100; # vro address, which is the IP address of the current dhcp server

Option subnet-mask limit 255.0; # subnet mask

# Fixed-address 192.168.145.155; # assign an ip address to the specified mac address

#}

}

[Root @ localhost zfp] #Vim/etc/sysconfig/dhcpd
DHCPDARGS = eth0 # specify to provide the dhcpserver service on the eth0 Nic

6. Enable the dhcp service.

[Root @ localhost zfp] #Service dhcpd status
Dhcpd (pid 4478) is running...
[Root @ localhost zfp] #

If an error is reported, check what error is reported when the dhcp service is enabled.Cat/var/log/messagesOrTail-f/var/log/messages &

The following is the log information for enabling the dhcp service normally:
