Linux 系统如何查看系统配置信息

一：cpu
[root@srv /]# more /proc/cpuinfo | grep "model name"
model name       : Intel(R) Xeon(R) CPU            X3220 @ 2.40GHz
model name       : Intel(R) Xeon(R) CPU            X3220 @ 2.40GHz
model name       : Intel(R) Xeon(R) CPU            X3220 @ 2.40GHz
model name       : Intel(R) Xeon(R) CPU            X3220 @ 2.40GHz
[root@srv /]# grep "model name" /proc/cpuinfo
model name       : Intel(R) Xeon(R) CPU            X3220 @ 2.40GHz
model name       : Intel(R) Xeon(R) CPU            X3220 @ 2.40GHz
model name       : Intel(R) Xeon(R) CPU            X3220 @ 2.40GHz
model name       : Intel(R) Xeon(R) CPU            X3220 @ 2.40GHz
[root@srv /]# grep "model name" /proc/cpuinfo | cut -f2 -d:
Intel(R) Xeon(R) CPU            X3220 @ 2.40GHz
Intel(R) Xeon(R) CPU            X3220 @ 2.40GHz
Intel(R) Xeon(R) CPU            X3220 @ 2.40GHz
Intel(R) Xeon(R) CPU            X3220 @ 2.40GHz
二：内存
[root@srv /]# grep MemTotal /proc/meminfo
MemTotal:        614400 kB
[root@srv /]# free -m
                    total        used        free      shared     buffers      cached
Mem:            600          23         576           0           0           0
-/+ buffers/cache:          23         576
Swap:             0           0           0
[root@srv /]# free -m |grep "Mem" |
