Linux-CentOS7.2

 CentOS7系列使用记录,最近开始把单位资源从windows迁移到Linux,作为一个过程记录写的本文。

官方镜像列表:https://www.centos.org/download/mirrors/

国内阿里云开源镜像站:http://mirrors.aliyun.com/centos/7.2.1511/os/x86_64/   这个链接是在安装时选择软件源时用的,注意开源镜像站下的os目录是网络安装用的,isos是下载后本地安装用的。之所以选择网络安装是因为镜像制作光盘之后始终无法选择软件源。

引导程序下载链接:http://isoredirect.centos.org/centos/7/isos/x86_64/      自己选择一个最快的下载就行。

我这里下载的是:http://mirrors.aliyun.com/centos/7.2.1511/isos/x86_64/CentOS-7-x86_64-NetInstall-1511.iso网络安装程序,比较小,下载快,主要是制作U盘比较快,完整安装版本的制作U盘时间太长了。网络安装选择上面给出的阿里云的镜像站点,在国内安装只要网络不是太差20分钟左右基本完成了。
