1 查看CPU

1.1 查看CPU個數(shù)
# cat /proc/cpuinfo | grep "physical id" | uniq | wc -l
2
**uniq命令：刪除重復(fù)行；wc –l命令：統(tǒng)計行數(shù)**

1.2 查看CPU核數(shù)
# cat /proc/cpuinfo | grep "cpu cores" | uniq
cpu cores : 4

1.3 查看CPU型號
# cat /proc/cpuinfo | grep 'model name' |uniq
model name : Intel(R) Xeon(R) CPU E5630 @ 2.53GHz

總結(jié)：該服務(wù)器有2個4核CPU，型號Intel(R) Xeon(R) CPU E5630 @ 2.53GHz

2 查看內(nèi)存

2.1 查看內(nèi)存總數(shù)
#cat /proc/meminfo | grep MemTotal
MemTotal: 32941268 kB //內(nèi)存32G

2.2 查看內(nèi)存條數(shù)
