配置 DHCP 服务 实现 ip 地址自动分配
目录
原因：由于公司使用 CentOS6.5 充当网关，为了避免麻烦给同事们一个个地去配置 IP 地址， 所以决定安装使用 dhcp 来自动分配 IP（之前是真一个一个去给他们配置 IP 地址，真他妈的累，烦，卖力而且不讨好~~）
1.安装DHCP
[root@localhost ~]# yum install -y dhcp2.配置dhcpd.conf
[root@localhost ~]# vim /etc/dhcp/dhcpd.conf
#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.sample
# see 'man 5 dhcpd.conf'
#
# 全局配置
# 设置客户端域名
option domain-name "wgsc.tv";
option domain-name-servers 192.168.1.60, 192.168.1.61;
# 默认租约12h
default-lease-time 43200;
# 最大租约24h
max-lease-time 86400;
# 不要ddns设定
ddns-update-style none;
# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
log-facility local7;
# 设置DHCP子网段
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.181 192.168.1.230;
option routers 192.168.1.1;
}

# ....省略一大串3.配置dhcp监听接口
[root@localhost ~]# vim /etc/sysconfig/dhcpd
# Command line options here
DHCPDARGS=eth0Tips: CentOS7 以后不需要设置
4.关闭iptables
[root@localhost ~]# /etc/inin.d/iptables stop
[root@localhost ~]# chkconfig iptables off5.启动dhcp服务
[root@localhost ~]# /etc/init.d/dhcpd start注： 启动日志信息可以查看
/var/log/message租约信息可查看/var/lib/dhcpd/dhcpd.leases
