PXE装机

PXE装机

1、关闭防火墙 SELLIUNX

systemctl stop firewalld
systemctl disable firewalld
setenforce 0
sed -i "s/^SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config

2、安装软件

1
2
yum -y install tftp-server httpd  dhcp
yum install syslinux -y

3、配置dhcp

cat /etc/dhcp/dhcpd.conf 
subnet 192.168.1.0  netmask 255.255.255.0  {
  range  192.168.1.100 192.168.1.200 ;
  default-lease-time 600;
  max-lease-time 7200;
  next-server 192.168.1.10;# 指明tftp服务器的地址
  filename "pxelinux.0";# 指明PXE文件位置，这个在申请ip的时候会发送给安装主机
}

4、配置tftp服务器

[root@localhost xinetd.d]# cat tftp 
# default: off
# description: The tftp server serves files using the trivial file transfer \
#       protocol.  The tftp protocol is often used to boot diskless \
#       workstations, download configuration files to network-aware printers, \
#       and to start the installation process for some operating systems.
service tftp
{
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -s /var/lib/tftpboot # 文件目录
        disable                 = no  #改成no
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}
sed -i '/disable/c\\tdisable\t\t\t=no' /etc/xinetd.d/tftp
[root@localhost xinetd.d]# systemctl restart tftp.socket 
[root@localhost xinetd.d]# systemctl status tftp.socket

cd /var/lib/tftpboot/
引导文件
cp /usr/share/syslinux/pxelinux.0 ./
菜单文件
cp /usr/share/syslinux/menu.c32 ./

挂载镜像
mount /dev/sdg /media/cdrom/
# 安装引导文件
cp /media/cdrom/isolinux/vmlinuz ./
cp /media/cdrom/isolinux/initrd.img ./
[root@localhost tftpboot]# ls
initrd.img  menu.c32  pxelinux.0  vmlinuz

[root@localhost pxeliunx.cfg]# touch default
编辑文件
[root@localhost pxeliunx.cfg]# cat default 
default menu.c32
timeout 100
prompt 0

label 1
menu lable ^1) Install Pai_CentOS7_1.5.1
menu default
kernel vmliunz
append initrd=initrd.img method=http://172.16.1.18/Centos7 ks=http://172.16.1.18/ks.cfg
