#化鲲为鹏，我有话说# 鲲鹏服务器信息巡检脚本

网友投稿 729 2022-05-29

一、背景

目前使用华为云鲲鹏服务器，对登录一个系统，快速查看其系统信息，检查系统各项指标及参数，编写系统快速检查脚本，输出系统信息到脚本运行的logs目录下。

二、脚本

git地址

#!/bin/bash # auth:kaliarch # func:sys info check # version:v1.0 # sys:centos6.x/7.x [ $(id -u) -gt 0 ] && echo "请用root用户执行此脚本！" && exit 1 sysversion=$(rpm -q centos-release|cut -d- -f3) line="-------------------------------------------------" [ -d logs ] || mkdir logs sys_check_file="logs/$(ip a show dev eth0|grep -w inet|awk '{print }'|awk -F '/' '{print }')-`date +%Y%m%d`.txt" # 获取系统cpu信息 function get_cpu_info() { Physical_CPUs=$(grep "physical id" /proc/cpuinfo| sort | uniq | wc -l) Virt_CPUs=$(grep "processor" /proc/cpuinfo | wc -l) CPU_Kernels=$(grep "cores" /proc/cpuinfo|uniq| awk -F ': ' '{print }') CPU_Type=$(grep "model name" /proc/cpuinfo | awk -F ': ' '{print }' | sort | uniq) CPU_Arch=$(uname -m) cat </dev/null) if [ ${sysversion} -gt 6 ];then service_config=$(systemctl list-unit-files --type=service --state=enabled|grep "enabled") run_service=$(systemctl list-units --type=service --state=running |grep ".service") else service_config=$(/sbin/chkconfig | grep -E ":on|:启用" |column -t) run_service=$(/sbin/service --status-all|grep -E "running") fi cat <#!/bin/bash # auth:kaliarch # func:sys info check # version:v1.0 # sys:centos6.x/7.x [ $(id -u) -gt 0 ] && echo "请用root用户执行此脚本！" && exit 1 sysversion=$(rpm -q centos-release|cut -d- -f3) line="-------------------------------------------------" [ -d logs ] || mkdir logs sys_check_file="logs/$(ip a show dev eth0|grep -w inet|awk '{print $2}'|awk -F '/' '{print $1}')-`date +%Y%m%d`.txt" # 获取系统cpu信息 function get_cpu_info() { Physical_CPUs=$(grep "physical id" /proc/cpuinfo| sort | uniq | wc -l) Virt_CPUs=$(grep "processor" /proc/cpuinfo | wc -l) CPU_Kernels=$(grep "cores" /proc/cpuinfo|uniq| awk -F ': ' '{print $2}') CPU_Type=$(grep "model name" /proc/cpuinfo | awk -F ': ' '{print $2}' | sort | uniq) CPU_Arch=$(uname -m) cat </dev/null) if [ ${sysversion} -gt 6 ];then service_config=$(systemctl list-unit-files --type=service --state=enabled|grep "enabled") run_service=$(systemctl list-units --type=service --state=running |grep ".service") else service_config=$(/sbin/chkconfig | grep -E ":on|:启用" |column -t) run_service=$(/sbin/service --status-all|grep -E "running") fi cat </dev/null|cut -d/ -f5;egrep -v "^$|^#" ${cronuser} 2>/dev/null;echo "";done) cat < ${sys_check_file}

三、测试
