查看cpu信息：lscpu
Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 48 //总逻辑CPU数：物理CPU个数*每个物理CPU核数*超线程数 On-line CPU(s) list: 0-47 Thread(s) per core: 2 //超线程数 Core(s) per socket: 12 //每个物理CPU核数 Socket(s): 2 //物理CPU个数 NUMA node(s): 2 Vendor ID: GenuineIntel CPU family: 6 Model: 79 Stepping: 1 CPU MHz: 2200.078 BogoMIPS: 4399.33 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 30720K NUMA node0 CPU(s): 0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46 NUMA node1 CPU(s): 1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39,41,43,45,47
查看内存信息：free -g
[[email protected] ~]# free -g total used free shared buffers cached Mem: 125 1 124 0 0 0 -/+ buffers/cache: 0 124 Swap: 62 0 62
//总内存为125G
查看硬盘信息：lsblk
[[email protected] ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 2.2T 0 disk ├─sda1 8:1 0 1G 0 part /boot ├─sda2 8:2 0 62.5G 0 part [SWAP] ├─sda3 8:3 0 48.8G 0 part / └─sda4 8:4 0 2.1T 0 part /app
