linux下查看cpu和memery信息
1.查内存

#more/proc/meminfo
cat /proc/meminfo
cat /proc/meminfo | grep MemTotal
[root@www proc]#more /proc/meminfo
MemTotal:     2054100 kB
MemFree:       840524 kB
Buffers:        61216 kB
Cached:        680756 kB
SwapCached:         0 kB
Active:        485172 kB
Inactive:      647160 kB
HighTotal:          0 kB
HighFree:           0 kB
LowTotal:     2054100 kB
LowFree:       840524 kB
SwapTotal:    2031608 kB
SwapFree:     2031508 kB

Hugepagesize:    2048 kB


#grep MemTotal /proc/meminfo(查内存总量)
[root@www proc]# grep MemTotal /proc/meminfo
MemTotal:     2054100 kB


2.查CPU

#more /proc/cpuinfo 查看CPU名称,主频,缓存等信息
[root@www proc]# more/proc/cpuinfo
