Linux(查看服务cpu核数和内存)

linux服务器中最重要的两个配置是CPU和内存。那么怎么开始查看CPU核数和内存,以及使用情况,是日常运维中使用最多的操作。

查看linux服务器cpu最简单的命令是 cat /proc/cpuinfo

查看linux服务器cpu最简单的命令是 lscpu

查看linux服务器内存

cat /proc/meminfo

查看linux服务器内存最简单的命令: free -h

lscpu信息

[root@tXX-XXX-app logs]# lscpu
Architecture:          x86_64
CPU op-mode(s):        32-bit, 64-bit
Byte Order:            Little Endian
CPU(s):                4
On-line CPU(s) list:   0-3
Thread(s) per core:    1
Core(s) per socket:    4
Socket(s):             1
NUMA node(s):          1
Vendor ID:             GenuineIntel
CPU family:            6
Model:                 85
Model name:            Intel(R) Xeon(R) Platinum 8255C CPU @ 2.50GHz
Stepping:              5
CPU MHz:               2494.140
BogoMIPS:              4988.28
Hypervisor vendor:     KVM
Virtualization type:   full
L1d cache:             32K
L1i cache:             32K
L2 cache:              4096K
L3 cache:              36608K
NUMA node0 CPU(s):     0-3

可以看出操作系统的架构是x86 64位的操作系统。

CPU 操作模型支持32位 和 64位

byte Order 为 Little Endian

cpu核数为 4核

CPU主频为2.50GHZ

CPU缓存为4级缓存,分别为32k 32k 4096K 36608K

free -h 内存信息

[root@tXX-XXX-app logs]# free  -h
              total        used        free      shared  buff/cache   available
Mem:            15G        6.2G        266M        1.1M        8.7G        8.7G
Swap:            0B          0B          0B

总内存 15G 已用 6.2G 可用8.7G

磁盘信息 du -h /home 查看home目录各文件夹占用磁盘空间大小。

[root@tXX-XX-app logs]# du -h  /home
