How to view the CPU and memory hardware information of the server under Linux

of a server under Linux

You can see the details of each CPU in the/proc/cpuinfo under 1,linux. But for a dual-core CPU, you will see two CPUs in the Cpuinfo. It is often mistaken for a two single-core CPU. In fact, Physical processor id should be adopted to differentiate between mono-and dual-core. and Physical processor id can find . flags  from Cpuinfo or DMESG if you have  ht  instructions to support Hyper-Threading Technology   Determine the number of physical CPUs can see the value of physical id , the same is the same physical CPU2, view memory size: CAT /PROC/MEMINFO |GREP MEMTOTAL3, Other commands and methods that can be used to view detailed information:uname -a                #  View kernel//information command head -n 1 /etc/issue   #  View version, is the number 1 is not the letter Lcat  /proc/cpuinfo      #  View Information Command hostname                #  View Linux System Information command for computer name lspci -tv               #  List all PCI devices LSUSB -TV               #  Lists Linux System Information commands for all USB devices Lsmod                  #   List the loaded kernel modules env                     #  View environment variable resource free -m                 #  view memory usage and swap area usage df -h                   #  view the usage of each partition Du -sh          #  View the size of the specified directory Grep memtotal /proc/meminfo    #  View Total Memory grep memfree /proc/meminfo    #  To view the amount of idle memory uptime                  #  View System uptime, number of users, load cat /proc/loadavg      #  view system load disk and partition mount  | column -t      #  View the status of a mounted partition fdisk -l                #  View all Partitions swapon -s               #  View All hdparm -i /dev/hda     #   View disk parameters (only for) dmesg | grep ide       #  To view the boot-time detection status network ifconfig               #   View all Properties iptables -l            #  View firewall Settings route -n                #  Viewing the routing table netstat -lntp          #  View all listening ports netstat -antp          #  View all established connections Netstat -s             #  viewing the network statistics process ps -ef                  #  View All Processes top                     #  real-time display of user w                        #  View Active User id              #  View specified user information last                    #  View Log cut -d: - /etc/passwd   #  View system All Users cut -d: - /etc/group    #  view system all groups crontab -l              #  View the current user's scheduled tasks service Chkconfig –list        #  List all system services chkconfig –list | grep on    #  Lists all system service programs that are started rpm -qa                 #  View all installed packages cat /proc/cpuinfo : View Linux system commands for CPU-related parameters cat /proc/partitions  : View the Linux hard disk and partition information System Information command cat /proc/meminfo : View Linux system memory Information Linux system command cat /proc/version : View version, similar to uname -rcat /proc/ioports : viewing device cat /proc/interrupts : viewing interrupts cat /proc/pci  : View information for PCI device CAT /PROC/SWAPS : View information for all swap partitions
