1 查看CPU

1.1 查看CPU个数
# cat /proc/cpuinfo | grep "physical id" | uniq | wc -l
2
**uniq命令：删除重复行；wc –l命令：统计行数

1.2 查看CPU核数
# cat /proc/cpuinfo | grep "cpu cores" | uniq
cpu cores : 4

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

总结：该服务器有2个4核CPU，型号Intel(R) Xeon(R) CPU E5630 @ 2.53GHz

2 查看内存

2.1 查看内存总数
#cat /proc/meminfo | grep MemTotal
MemTotal: 32941268 kB //内存32G

2.2 查看内存条数
