PXE 02-CentOS6部署PXE

1. 部署http服务，我使用Nginx

yum install -y nginx

2. 安装dhcp服务

yum install -y dhcp

配置dhcp

[root@PXE ~]# cat /etc/dhcp/dhcpd.conf 
filename "pxelinux.0";
next-server 192.168.124.75;
subnet 192.168.124.0 netmask 255.255.255.0 {
  range 192.168.124.80 192.168.124.99;
  option subnet-mask 255.255.255.0;
}

开启服务

service dhcpd start

3. 安装其他服务

yum install -y tftp-server syslinux

[root@PXE ~]# cat /etc/xinetd.d/tftp 
service tftp
{
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -s /var/lib/tftpboot
        disable                 = no
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}

service xinetd start

4. 下载镜像

mkdir /mnt/cdrom
mount /dev/cdrom /mnt/cdrom

mkdir /application/nginx/html/centos6
cp -r /mnt/cdrom/* /application/nginx/html/centos6/

5. 安装kickstart

yum install -y system-config-kickstart

6. 配置安装要求

mkdir /application/nginx/html/ksdir/
vi /application/nginx/html/ksdir/ks6.cfg

%end

chmod +r  /application/nginx/html/ksdir/ks6.cfg

7. 部署加载文件

cp /application/nginx/html/centos6/isolinux/{initrd.img,vmlinuz,boot.msg} /var/lib/tftpboot/
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
mkdir /var/lib/tftpboot/pxelinux.cfg

[root@PXE pxelinux.cfg]# cat /var/lib/tftpboot/pxelinux.cfg/default
