背景：

PXE+Kickstart安装CentOS 7.3

Linux系统版本：CentOS 7.3
软件版本：yum  epel源

主机IP：    192.168.8.35
需要软件：tftp-server dhcp syslinux xinetd system-config-kickstart nginx

[root@node1 ~]# yum -y install tftp-server dhcp syslinux xinetd system-config-kickstart

[root@node1 ~]# cp /usr/share/doc/dhcp-4.2.5/dhcpd.conf.example /etc/dhcp/dhcpd.conf

[root@node1 ~]# vim /etc/dhcp/dhcpd.conf    # 添加如下行

subnet 192.168.8.0 netmask 255.255.255.0 {
        option routers 192.168.8.35;
        range 192.168.8.103 192.168.8.200;
        option domain-name-servers 192.168.8.35;
        filename "pxelinux.0";
        next-server 192.168.8.35;
        default-lease-time 600;
        max-lease-time 7200;
}

# 改完之后重新dhcpd

# 命令详解
# option routers                dhcp路由地址
# range                            dhcp分配地址池
# default-lease-time          dhcp默认时长
# filename                          pxe服务名称
# next-server                pxe服务器地址
# allow members            pxe最大值

vim /etc/xinetd.d/tftp
    disable                = no
# 将disable 改为no  改完之后重新瞬间守护进程

# 配置nginx

[root@node1 ~]# vim /etc/nginx/nginx.conf    添加一个server段
