View the CPU, memory, and operating system version information for the CentOS server

Often to see the Linux server CPU, memory, operating system version and other information, summarize the commonly used commands

1. View CPU model (32 logical CPUs)

[Email protected] ~]# cat/proc/cpuinfo |grep "name" |cut-f2-d: |uniq-c

Intel (R) Xeon (r) CPU e5-4620 v2 @ 2.60GHz

2. View the number of physical CPUs (two 16-core CPUs)

[Email protected] ~]# cat/proc/cpuinfo | grep "Physical" | sort |uniq-c

Address sizes: physical, bits virtual

Physical ID: 0

Physical ID: 1

3. See how many bit patterns the CPU is running under

[Email protected] ~]# getconf long_bit

64

4. The following results are greater than 0, indicating support for 64-bit operating systems

[Email protected] ~]# cat/proc/cpuinfo | grep flags | grep ' LM ' | wc-l

32

5. View the size of the system's physical memory

[Email protected] ~]# free-m
