Linux（查看服务cpu核数和内存）

linux服务器中最重要的两个配置是CPU和内存。那么怎么开始查看CPU核数和内存，以及使用情况，是日常运维中使用最多的操作。

查看linux服务器cpu最简单的命令是 cat /proc/cpuinfo

查看linux服务器cpu最简单的命令是 lscpu

查看linux服务器内存

cat /proc/meminfo

查看linux服务器内存最简单的命令： free -h

lscpu信息

[root@tXX-XXX-app logs]# lscpuArchitecture:          x86_64CPU op-mode(s):        32-bit, 64-bitByte Order:            Little EndianCPU(s):                4On-line CPU(s) list:   0-3Thread(s) per core:    1Core(s) per Socket:    4Socket(s):             1NUMA node(s):          1Vendor ID:             GenuineIntelCPU family:            6Model:                 85Model name:            Intel(R) Xeon(R) Platinum 8255C CPU @ 2.50GHzStepping:              5CPU MHz:               2494.140BoGoMIPS:              4988.28Hypervisor vendor:     KVMVirtualization type:   fullL1d cache:             32KL1i cache:             32KL2 cache:              4096KL3 cache:              36608KNUMA node0 CPU(s):     0-3

可以看出操作系统的架构是x86 64位的操作系统。

CPU 操作模型支持32位 和 64位

byte Order 为 Little Endian

cpu核数为 4核

CPU主频为2.50GHZ

CPU缓存为4级缓存，分别为32k  32k  4096K  36608K

free -h 内存信息

[root@tXX-XXX-app logs]# free  -h              total        used        free      shared  buff/cache   availableMem:            15G        6.2G        266M        1.1M        8.7G        8.7GSwap:            0B          0B          0B

总内存 15G 已用 6.2G 可用8.7G

磁盘信息 du -h /home 查看home目录各文件夹占用磁盘空间大小。

[root@tXX-XX-app logs]# du -h  /home44M     /home/Docker/apps/eureka8.0K    /home/docker/apps/Nginx/conf.d/bak_2023022716K     /home/docker/apps/nginx/conf.d8.0K    /home/docker/apps/nginx/conf/bak_2023022724K     /home/docker/apps/nginx/conf29M     /home/docker/apps/nginx/www/ctg-member/ctg-member/assets30M     /home/docker/apps/nginx/www/ctg-member/ctg-member30M     /home/docker/apps/nginx/www/ctg-member30M     /home/docker/apps/nginx/www12G     /home/docker/apps/nginx/logs20K     /home/docker/apps/nginx/cert12G     /home/docker/apps/nginx12G     /home/docker/apps16K     /home/docker/script/apollo36K     /home/docker/script12G     /home/docker392M    /home/project/ctg-member-plat/jar8.1M    /home/project/ctg-member-plat/logs16K     /home/project/ctg-member-plat/script/subscript28K     /home/project/ctg-member-plat/script400M    /home/project/ctg-member-plat52M     /home/project/sso/jar56K     /home/project/sso/logs8.0K    /home/project/sso/script52M     /home/project/sso451M    /home/project12K     /home/Redis/myredis/data/appendonlydir16K     /home/redis/myredis/data24K     /home/redis/myredis28K     /home/redis67M     /home/tingyun13G     /home
