总体规划：
搭建一台实验用服务器 系统 centos6.6 172.16.66.66/24
并配置PXE+DHCP+vsftpd+tftp+KICKSTART,实现pxe启动网络自动话安装系统，自动分配主机名与ip地址。
安装 配置vsftp服务器做yum源
--------------------------------------我是分割线---------------------------------------------------
现在开始第一步搭建服务器
网络选用nat模式 关闭dhcp
安装系统略。。不需要桌面所以选择basic server
设置网络[root@server ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0HWADDR=52:54:00:c8:5a:8bTYPE=EthernetUUID=b241c467-6618-414d-876e-1143a8baec0cONBOOT=yesNM_CONTROLLED=yesBOOTPROTO=noneIPADDR=172.16.8.88NETMASK=255.255.255.0GATEWAY=172.16.8.1IPV6INIT=noUSERCTL=noDNS1=172.16.8.1[root@server ~]# service network restart #重启网卡[root@server ~]# ping -c2 172.16.8.1 [root@server ~]# ping -c2 www.baidu.com确认可以通外网然后开启内核路由转发[root@server ~]# vim /etc/sysctl.conf net.ipv4.ip_forward = 1 [root@server ~]# sysctl -pnet.ipv4.ip_forward = 1net.ipv4.conf.default.rp_filter = 1net.ipv4.conf.default.accept_source_route = 0kernel.sysrq = 0kernel.core_uses_pid = 1net.ipv4.tcp_syncookies = 1有了ip地址就可以在opensuse下直接ssh了zhou@zhou:~> ssh root@172.16.8.88 安装ftp服务[root@server ~]# yum install vsftpd -y[root@server ~]# service vsftpd start #启动服务 Starting vsftpd for vsftpd: [ OK ][root@server ~]# chkconfig vsftpd on #设置开机自启动[root@server ~]# mkdir /var/ftp/centos6.6[root@server ~]# mount /dev/cdrom /var/ftp/centos6.6/mount: block device /dev/sr0 is write-protected, mounting read-only[root@server ~]# rm -rf * /etc/yum.repos.d/*[root@server ~]# vim /etc/yum.repos.d/centos6.6.repo[centos-3glong]name=3glong.combaseurl=ftp://172.16.8.88/centos6.6enabled=1gpgcheck=0[root@server ~]# yum makecache已加载插件：fastestmirror, securityDetermining fastest mirrorsftp://172.16.8.88/centos6.6/repodata/repomd.xml: [Errno 14] PYCURL ERROR 9 - "Server denied you to change to the given directory"尝试其他镜像。错误：Cannot retrieve repository metadata (repomd.xml) for repository: centos-3glong.

新建虚拟机试试选网络引导
提示网络不支持什么的直接无视，因为我们已经配置支持了
全自动安装无需人工操作
安装完成后主机名与ip对应
