First, hardware information
1, total number of cores = number of physical CPUs x number of cores per physical CPU # Total Logical CPUs = number of physical CPUs x number of cores per physical CPU X number of hyper-threads
2. View the number of physical CPUs
cat/proc/cpuinfo| grep "Physical ID" | Sort| uniq| Wc-l
3. View the number of cores in each physical CPU (that is, the number of nuclei)
cat/proc/cpuinfo| grep "CPU Cores" | Uniq
4. View CPU information (model number)
Cat/proc/cpuinfo | grep name | Cut-f2-d: | Uniq-c
5. Check the number of CPU cores
Grep-c ' model name '/proc/cpuinfo
6. Check hard disk sn
Hdparm-i/DEV/SDA
7. Check memory slot number and usage status
Dmidecode | Grep-a16 "Memory device$" |grep Size
8. Check the motherboard configuration
Dmidecode |more DMESG |more
