本文我们来分享一个获取Linux服务器信息的Shell脚本,此脚本已在ubuntu、centos测试通过,本文脚本可以获取Linux发行版本,操作系统是不是64位的.
此脚本已经在ubuntu以及centos版本上测试通过,直接上源代码比较爽:
- #!/bin/bash
- Line='==========='
- #linux发行版名称
- if [[ -f /usr/bin/lsb_release ]]; then
- OS=$(/usr/bin/lsb_release -a |grep Description |awk -F : '{print $2}' |sed 's/^[ t]*//g')
- else
- OS=$(cat /etc/issue |sed -n '1p')
- fi
- echo -e "${Line}nOS:n${OS}n${Line}"
- ######################################################################################################
- #查看系统是否为64位:uname -m,若出现x86_64,则为64位
- OS_version=$(uname -m)
- echo -e "OS_version:n${OS_version}n${Line}"
- #系统内核版本
- kernel_version=$(uname -r)

- #cpu型号

- #查看CPU是否支持64位技术:grep 'flags' /proc/cpuinfo,若flags信息中包含lm字段,则支持64位
- Numbers=$(grep 'lm' /proc/cpuinfo |wc -l)
- if (( ${Numbers} > 0)); then lm=64
- else lm=32
- fi
- echo -e "Support Mode Of CPU:n${lm}n${Line}"

- #Memtotal 内存总大小

- #查看内存类型、频率、条数、最大支持内存等信息:dmidecode -t memory,或dmidecode | grep -A16 "Memory Device$"
- #下面为统计内存条数
- Number=$(dmidecode | grep -A16 "Memory Device$" |grep Size|sort |sed 's/^[ t]*//g'| grep -v 'No Module Installed' | wc -l)
- echo -e "Number of Physical Memory:n${Number}n${Line}"
- #SwapTotal swap分区总大小
- SwapTotal=$(cat /proc/meminfo |grep 'SwapTotal' |awk -F : '{print $2}' |sed 's/^[ t]*//g')
- echo -e "Total Swap:n${SwapTotal}n${Line}"

- #显示硬盘,以及大小
- Disk=$(fdisk -l |grep 'Disk' |awk -F , '{print $1}' | sed 's/Disk identifier.*//g' | sed '/^$/d')

- Partion=$(df -hlP |sed -n '2,$p')
- echo -e "Usage Of partions:n${Partion}n${Line}"
