1：运行A或B查看Linux版本
A、[root@linuxzgf ~]#file /sbin/init
/sbin/init: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped
32-bit即是32位的 linux, 如是64位的, 显示的是 64-bit
B、 [root@linuxzgf ~]#file /bin/cat
/bin/cat: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped
32-bit即是32位的 linux, 如是64位的, 显示的是 64-bit
2：修改/etc/yum.repos.d/CentOS-Base.repo
vim /etc/yum.repos.d/CentOS-Base.repo
根据你的系统增加一个节点
