规划设计：
CentOS 764bit最小化安装利用应答文件，安装为核心安装，配置好CentOS基本应用和网络。为后期基本服务器的安装做准备。（本安装为虚拟机安装）
准备：
VMware 10 、CentOS 7.0的镜像文件，安装的应答文件
应答文件位置：http://192.168.188.1/mini.txt
最小化安装
1、通过kickstart文件来简化管理
（系统安装应答文件）

安装过程
新建虚拟机
选择稍后安装系统
选着CentOS 7 64位版本
选择保存路径
虚拟机的基本设置
编辑虚拟机设置添加镜像文件
CentOS 7的配置

网络命令查看IP
# ifconfig
-bash: ifconfig: command not found //没有发现这个命令
# find /-name ifconfig //查询这个命令对应的目录
没有这个文件
在RHEL 6.4上查看一下ifconfig属于那个包
# rpm -qf/sbin/ifconfig //查看这个命令所依赖的包
net-tools-1.60-110.el6_2.x86_64
CentOS的Mini最小化安装@core中没有包含net-tools包
# mount/dev/cdrom /mnt/cdrom/ //挂载光驱到目录
# cd/mnt/cdrom/Packages/ //进入目录
# rpm -ivhnet-tools-2.0-0.17.20131004git.el7.x86_64.rpm //安装包

重启CentOS 7 基本配置完成
总结：
CentOS的核心安装也是他的最小化安装，这样可以为基本服务器的安装提供一个干净的实验环境。另外也可以让我们后期的试验中了解CentOS 7的功能，让和我一样的菜鸟了解个多的东西。
