使用TFTP、DHCP、NFS，网络PEX批量部署Linux

[root@ www.bkjia.com ~]# yum install tftp-server -y 安装tftp服务 安装完启动

[root@ www.bkjia.com 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.bkjia.com ~]# netstat -tunlp |grep 69 确保69端口打开状态
 
[root@ www.bkjia.com ~]# yum install dhcp -y 安装dhcp服务（安装过程出错，卸载dhclient安装成功）
 
[root@ www.bkjia.com ~]# vi /etc/dhcp/dhcpd.conf 修改dhcp配置文件

  option broadcast-address 192.168.0.0;
}
 
 
 
[root@ www.bkjia.com mnt]# mkdir -p /tftpboot 创建dhcp服务指定目录
[root@ www.bkjia.com tftpboot]# cd /tftpboot/ 进入目录
[root@localhost tftpboot]# yum install syslinux -y
[root@ www.bkjia.com tftpboot]# cp /usr/share/syslinux/pxelinux.0  ./ 复制pxelinux.0配置文件到/tftpboot
 
 
[root@ www.bkjia.com tftpboot]# mount -t iso9660 /dev/cdrom /mnt/cdrom/ 挂载CentOS系统镜像
[root@localhost tftpboot]# cp /mnt/cdrom/isolinux/vmlinuz ./
[root@localhost tftpboot]# cp /mnt/cdrom/isolinux/initrd.img  ./
[root@ www.bkjia.com tftpboot]# mkdir -p pxelinux.cfg 创建PXE服务的配置文件夹
[root@ www.bkjia.com tftpboot]# cp /mnt/cdrom/isolinux//isolinux.cfg pxelinux.cfg/default 复制ISO镜像中的isolinux.cfg 并重命名为default
[root@ www.bkjia.com tftpboot]# vi pxelinux.cfg/default  配置默认的配置
