## Linux如何搭建dhcp ##

一、用yum安装dhcp  
1)安装yum源  
详情请看[添加链接描述][Link 1]  
2)安装dhcp

yum install dhcp -y

二、修改文件完成dhcp搭建

[root@foundation72 yum.repos.d]# rpm -qc dhcp
    /etc/dhcp/dhcpd.conf
    /etc/dhcp/dhcpd6.conf
    /etc/openldap/schema/dhcp.schema
    /etc/sysconfig/dhcpd
    /var/lib/dhcpd/dhcpd.leases
    /var/lib/dhcpd/dhcpd6.leases
    [root@foundation72 yum.repos.d]# vim /etc/dhcp/dhcpd.conf

复制：/usr/share/doc/dhcp\*/dhcpd.conf.example  
![在这里插入图片描述][20190122213748798.png]

[root@foundation72 yum.repos.d]# cp /usr/share/doc/dhcp*/dhcpd.conf.example /etc/dhcp/dhcpd.conf
    cp: overwrite ‘/etc/dhcp/dhcpd.conf’? y
    [root@foundation72 yum.repos.d]# vim /etc/dhcp/dhcpd.conf

此时/etc/dhcp/dhcpd.conf文件内容如下图：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDI5NzMwMw_size_16_color_FFFFFF_t_70]  
修改为：

6 # option definitions common to all supported networks...
      7 option domain-name "lee.org";        ##名字可以不改
      8 option domain-name-servers 114.114.114.114;    ##设置dns
      9 
     10 default-lease-time 600;                        ##最少600h
     11 max-lease-time 7200;                           ##最多7200h

31--34行可根据自己具体需求更改
     29 # This is a very basic subnet declaration.
     30 
     31   subnet 172.25.254.0 netmask 255.255.255.0 {    ##其网络区域
     32   range 172.25.254.50 172.25.254.99;           ##给ip范围
     33   option routers 172.25.254.205;               ##给网关
     34 }
     在此之后的信息没啥用，全删了

重启dhcp

systemctl start dhcpd

\-------完成
