CPU

# 总核数 = 物理CPU个数 X 每颗物理CPU的核数 
# 总逻辑CPU数 = 物理CPU个数 X 每颗物理CPU的核数 X 超线程数

# 查看物理CPU个数
cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l

# 查看每个物理CPU中core的个数(即核数)
cat /proc/cpuinfo| grep "cpu cores"| uniq

# 查看逻辑CPU的个数
cat /proc/cpuinfo| grep "processor"| wc -l

# 查看CPU信息（型号）
cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c

MEM

# 每个内存插槽上的详细信息
dmidecode | grep -A16 "Memory Device$"
# 总内存
free -h

DISK

lsblk

fdisk -l

# io信息
iostat -x 10

Network

ifconfig

# 网关
netstat -rn
ip route show

# 路由
route -n

# DNS
dig |grep SERVER

MegaCli

安装

# raid信息依赖MegaCli去查看

# 下载MegaCli包
https://docs.broadcom.com/docs-and-downloads/raid-controllers/raid-controllers-common-files/8-07-10_MegaCLI_Linux.zip

# 解压后传到服务器上
rpm -ivh MegaCli-8.07.10-1.noarch.rpm

# 默认安装到opt下，做个软链
ln -s /opt/MegaRAID/MegaCli/MegaCli64 /usr/bin/

MegaCli64 -v

使用

#  查raid卡信息
MegaCli64 -AdpAllInfo -aALL

# 查看raid信息及raid组成磁盘信息
MegaCli64 -LdPdInfo -aALL
