DHCP是Dynamic Host Configuration Protocol(动态主机配置协议)的简写形式,使用DHCP协议可以为客户端主机自动分配TCP/IP参数信息,如IP地址,子网掩码,网关、DNS等。
安装yun –y install dhcp
默认状态下dhcp服务会将日志保存在/var/log/messages文件中,如果遇到服务器故障问题,可以检查该文件。配置文件在于/etc/dhcp/dhcpd.conf文件中。
[root@localhost ~]# gedit /etc/dhcp/dhcpd.conf
配置文件:
#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.sample
# see ‘man 5 dhcpd.conf‘
#
#
subnet 192.168.118.0 netmask 255.255.255.0 {
range 192.168.118.5 192.168.118.15;
option domain-name-servers boot.example.com;
option domain-name "boot.example.com";
option routers 192.168.118.1;
default-lease-time 600;
max-lease-time 7200;
next-server 192.168.118.253;
filename "pxelinux.0";
}
也可以指定主机,并分配给它ip。
默认状态下,dhcp服务将会将日志保存在/var/log/messages文件中,如果遇到服务器故障问题,可以检查该文件。网络参数租期为/var/lib/dhcpd/dhcpd.leases,可以通过检查该文件查看服务器已经分配的资源和相关租期信息。
[root@localhost /]# cat /var/lib/dhcpd/dhcpd.leases
# The format of this file is documented in the dhcpd.leases(5) manual page.
# This lease file was written by isc-dhcp-4.1.1-P1
