1. 查看cpu型号、内核数：
[root@shoubashou ~]# less /proc/cpuinfo | grep "model name"
model name : Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz
model name : Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz
model name : Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz
model name : Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz
[root@shoubashou ~]# grep "model name" /proc/cpuinfo
model name : Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz
model name : Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz
model name : Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz
model name : Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz
2. 查看cpu是32位还是64位
[root@shoubashou ~]# uname -a

[root@shoubashou ~]# echo $HOSTTYPE
x86_64
[root@shoubashou ~]# getconf LONG_BIT
64
[root@shoubashou ~]# file /bin/ls
