PXE部署centos7.6

配置yum

关闭防火墙

一、安装TFTP、xinetd、syslinux

yum install -y tftp-server xinetd

vim /etc/xinetd.d/tftp  #修改TFTP服务的配置文件，如下：

   service tftp

    {

  socket_type             = dgram

           protocol                = udp                     #TFTP默认使用的UDP协议

            wait                    = yes                       #yes：客户机单台连接，no：多台连接

           user                    = root

           server                  =/usr/sbin/in.tftpd        #指定TFTP跟目录（引导文件的存储路径）

           server_args             = -s/var/lib/tftpboot

           disable                 = no                        #no：表示开启TFTP服务

           per_source              = 11

           cps                     = 100 2

           flags                   = IPv4

}

二、开启TFTP、DHCP服务并设置为开机自启动

systemctl start tftp

systemctl start xinetd

systemctl start dhcpd


systemctl enable tftp

systemctl enable xinetd

systemctl enable dhcpd


查看是否为开机启动 systemctl is-enable tftp

systemctl is-enable xinetd

三、使用yum安装dhcp服务

yum install -y dhcp

cp /usr/share/doc/dhcp-4.2.5/dhcpd.conf.example /etc/dhcp/dhcpd.conf

四、修改dhcp的配置文件并开启dhcp服务

PXE部署centos7.6_centos

注意：配置文件错误，dhcp无法启动


五、准备Linux内核、初始化镜像文件

将镜像里的pxeboot目录下所有文件复制到 /var/lib/tftpboot/ -----系统引导文件



六、安装syslniux

yum install -y syslinux

七、将PXE引导文件复制到TFTP的根目录上

cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/

PXE部署centos7.6_linux_02


八、安装FTP服务,准备CentOS 7安装源

yum install -y vsftpd

systemctl start vsftpd

systemctl enable vsftpd


mkdir /var/ftp/centos7

cp -rf /mnt/* /var/ftp/centos7

PXE部署centos7.6_System_03



九、配置启动菜单文件

mkdir /var/lib/tftpboot/pxelinux.cfg ------------创建pxelinux.cfg目录

vi /var/lib/tftpboot/pxelinux.cfg/default

PXE部署centos7.6_centos_04


十、配置无人值守安装

yum -y install system-config-kickstart

system-config-kickstart

十一、配置ks文件

vi /var/ftp/ks.cfg

%post --interpreter=/bin/bash

mkdir /etc/yum.repos.d/repo.bak

mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/repo.bak

echo"[local]
