• 在Linux下使用命令查看服务器配置信息

    有许多命令可以用来查看 Linux 系统上的硬件信息。有些命令只能够打印出像 CPU 和内存这一特定的硬件组件信息,另外一些命令可以查看多种硬件组件的信息。这个教程可以带大家快速了解一下查看各种硬件设备的信息和配置详情的最常用的命令。 查看服务器型号 dmidecode | grep "System Information" -A9 | egrep "Manufacturer|Product" Manufacturer: Sugon Product Name: W580-G20 查看操作系统 cat /etc/redhat-release CentOS Linux release 7.3.1611 (Core) lsb_release -a LSB Version: :core-4.1-amd64:core-4.1-noarch Distributor ID: CentOS Description: CentOS Linux release 7.3.1611 (Core) Release: 7.3.1611 Codename: Core 查看CPU信息 cat /proc/cpuinfo lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 12 On-line CPU(s) list: 0-11 Thread(s) per core: 1 Core(s) per socket: 6 Socket(s): 2 NUMA node(s): 2 Vendor ID: GenuineIntel CPU family: 6 Model: 63 Model name: Intel(R) Xeon(R) CPU E5-2609 v3 @ 1.90GHz Stepping: 2 CPU MHz: 1780.062 BogoMIPS: 3805.02 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 15360K NUMA node0 CPU(s): 0-5 NUMA node1 CPU(s): 6-11 查看CPU型号 cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c 12 Intel(R) Xeon(R) CPU E5-2609 v3 @ 1.90GHz 查看逻辑CPU个数 cat /proc/cpuinfo |grep name |cut -d: -f2 |uniq -c cat /proc/cpuinfo| grep "processor"| wc -l 查看物理CPU个数 cat /proc/cpuinfo |grep "physical id" |sort -u |wc -l 查看每个物理CPU中core的个数(即核数) cat /proc/cpuinfo | grep "cpu cores" | uniq cpu cores : 6 top命令 top后按1可以看到多少个CPU 查看磁盘信息 fdisk -l 查看内存的插槽数,已经使用多少插槽,每条内存多大 dmidecode | grep -A5 "Memory Device" | grep Size |grep -v Range Size: 32 GB Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: 32 GB Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed 查看硬盘和分区分布 lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 558.9G 0 disk ├─sda1 8:1 0 1G 0 part /boot └─sda2 8:2 0 557.9G 0 part ├─cl-root 253:0 0 50G 0 lvm / ├─cl-swap 253:1 0 31.4G 0 lvm [SWAP] └─cl-home 253:2 0 476.5G 0 lvm /home sr0 11:0 1 1024M 0 rom 查看网卡的硬件信息 lspci | grep -i 'eth'
