使用tftp、dhcp、nfs，網絡PEX批量部署linux

[root@www ~]# yum install tftp-server -y 安裝tftp服務 安裝完啟動

[root@www mnt]# vi /etc/xinetd.d/tftp 修改tfpt配置
service tftp
{
        disable = no
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -u nobody -s /tftpboot
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}
[root@www ~]# netstat -tunlp |grep 69 確保69端口打開狀態
[root@www ~]# yum install dhcp -y 安裝dhcp服務（安裝過程出錯，卸載dhclient安裝成功）
[root@www ~]# vi /etc/dhcp/dhcpd.conf 修改dhcp配置文件
option domain-name "cnnb.com";
option domain-name-server 220.189.220.67;
filename "pxelinux.0";
net-server 192.168.0.241;
default-lease-time 600;
max-lease-time 7200;
subnet 192.168.0.0 netmask 255.255.255.0{
range 192.168.0.242 192.168.0.243;
option broadcast-address 192.168.0.0;
}
[root@www mnt]# mkdir -p /tftpboot 創建dhcp服務指定目錄
[root@www tftpboot]# cd /tftpboot/ 進入目錄
[root@localhost tftpboot]# yum install syslinux -y
[root@www tftpboot]# cp /usr/share/syslinux/pxelinux.0  ./ 復制pxelinux.0配置文件到/tftpboot
[root@www tftpboot]# mount -t iso9660 /dev/cdrom /mnt/cdrom/ 掛載centos系統鏡像
[root@localhost tftpboot]# cp /mnt/cdrom/isolinux/vmlinuz ./
[root@localhost tftpboot]# cp /mnt/cdrom/isolinux/initrd.img  ./
[root@www tftpboot]# mkdir -p pxelinux.cfg 創建PXE服務的配置文件夾
[root@www tftpboot]# cp /mnt/cdrom/isolinux//isolinux.cfg pxelinux.cfg/default 復制ISO鏡像中的isolinux.cfg 並重命名為default
[root@www tftpboot]# vi pxelinux.cfg/default  配置默認的配置
default linux

配置好後重啟tftp

[root@www tftpboot]# mkdir -p /centosinstall 創建NFS的ISO鏡像目錄

[root@www tftpboot]# cp -rf /mnt/cdrom/* /centosinstall/ 復制鏡像中的文件到/centosinstall/

[root@www mnt]# vi /etc/exports 設置共享

/centosinstall *(rw,sync)

[root@www mnt]# cd /centosinstall/ 進入/centosinstall/文件夾

[root@www centosinstall]# vi ks.cfg 創建ks.cfg配置文件
