在CentOS系统中,可以通过以下几种方法来检查CPU信息:
lscpu命令lscpu命令可以显示CPU架构的信息。
lscpu
输出示例:
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 4
On-line CPU(s) list: 0-3

L1d cache: 32K
L1i cache: 32K
L2 cache: 256K
L3 cache: 8192K
NUMA node0 CPU(s): 0-3
cat /proc/cpuinfo命令这个命令会显示详细的CPU信息。
cat /proc/cpuinfo

power management:
dmidecode命令dmidecode是一个用于显示硬件系统部件信息的工具,需要root权限。
sudo dmidecode -t processor
输出示例:
Handle 0x001E, DMI type 4, 42 bytes

top或htop命令这两个命令可以实时显示系统资源的使用情况,包括CPU使用率。
top
或者安装并使用htop:
sudo yum install htop
htop
这些方法可以帮助你全面了解CentOS系统中CPU的详细信息和使用情况。
