脚本说明：
在RedHat5.4，5.5版本测试通过，显示CPU，内存，硬盘，网络的基本信息；运行后的结果是（虚拟机）：

显示基本信息：
主要是使用dmidecode命令查看基本的信息，取System Inforamtion行下面的行，使用sed -n '/System Information/{n;n;p;}'
#Machine_Detail hostname=$(hostname) machine_name=$(dmidecode|sed -n '/System Information/{n;p;}'|sed 's/^.*://g') version=$(cat /proc/version|sed 's/(.*$//g') linux_version=$(head -n 1 /etc/issue) machine_number=$(dmidecode|sed -n '/System Information/{n;n;p;}'|sed 's/^.*\[//g'|sed 's/\].*$//g') machine_kind=$(dmidecode|sed -n '/System Information/{n;n;p;}'|sed 's/.*://g'|sed 's/-.*$//g') machine_SN=$(dmidecode|sed -n '/System Information/{n;n;n;n;p;}'|sed 's/^.*: //g') echo "******************" echo "******Detail******" echo "Hostname: $hostname" echo "Machine_name: $machine_name" echo "Version: $version" echo "Linux_Version: $linux_version" echo "Machine_kind: $machine_kind" echo "SN: $machine_SN" echo "MT: $machine_number"
CPU：
主要是查看/proc/cpuinfo里面的内容，对physical id和core id做统计，得出的物理/逻辑CPU和进程数
#CPU total_physical_CPU_num=$(cat /proc/cpuinfo|grep "physical id"|sort|uniq|wc -l) cpu_bit=$(getconf LONG_BIT) core_num_per_physical=$(cat /proc/cpuinfo|grep "core id"|sort|uniq|wc -l) total_core_num=$(($core_num_per_physical*$total_physical_CPU_num)) total_processor_num=$(cat /proc/cpuinfo|grep "processor"|wc -l) CPU_name=$(cat /proc/cpuinfo|grep "model name"|uniq|sed 's/^.*://g') echo "****CPU****" echo "CPU_Name: $CPU_name" echo "Total_physical_CPU: $total_physical_CPU_num" echo "Total_core_num: $total_core_num" echo "Total_Processor_num: $total_processor_num" echo "CPU_BIT: $cpu_bit"
内存：
还是使用dmidecode，提取Memory Device行下的16行内容，使用grep -A16 "Memory Device"
#Memory total_mem=$(grep MemTotal /proc/meminfo | sed 's/^[^0-9]*//g'|sed 's/kB//g') total_mem_g=$(($total_mem/1048576)) memory_Hz=$(dmidecode|grep -A16 "Memory Device" | grep 'Speed'|uniq |grep 'Hz'|sed 's/^.*: //g'|uniq) memory_max=$(dmidecode | grep "Maximum Capacity"|sed 's/^.*: //g') memory_list=$(dmidecode|grep -A5 "Memory Device"|grep Size) memory_num=$(dmidecode|grep -A5 "Memory Device"|grep Size -c) memory_num_used=$(dmidecode|grep -A5 "Memory Device"|grep MB -c) echo "*****Memory******" echo "Total_Mem: $total_mem KB" echo "Total_Mem: $total_mem_g G" echo "Mem_Hz: $memory_Hz" echo "Mem_Max: $memory_max" echo "Memory_Num: $memory_num" echo "Memory_Num_Used: $memory_num_used" echo "Mem_list:" echo "$memory_list"
Disk&Net
一般的服务器会有eth0和eth1，判断是否有eth0和eth1，并根据情况进行输出，并输出net_list检查有没有其他的网卡
#Disk total_disk=$(fdisk -l | grep '^Disk'| sed 's/,.*//g') echo "****Disk****" echo "Total_Disk: $total_disk" #Net echo "****Net Info****" net_list=$(ifconfig |grep 'Link encap:'|sed 's/ .*$//g') is_eth0=$(ifconfig|grep 'eth0' -c) is_eth1=$(ifconfig|grep 'eth1' -c) [ is_eth0 != 0 ] && ip_addr=$(ifconfig eth0|grep 'inet addr' | sed 's/^.*inet addr://g'|sed 's/ .*$//g') [ is_eth0 != 0 ] && mac_addr=$(ifconfig eth0|grep "HWaddr"| sed 's/^.*HWaddr //g') [ $is_eth1 != 0 ] && eth1_mac_addr=$(ifconfig eth1|grep "HWaddr"| sed 's/^.*HWaddr //g') [ $is_eth1 != 0 ] && eth1_ip_addr=$(ifconfig eth1|grep 'inet addr'|sed 's/^.*inet addr://g'|sed 's/ .*$//g') [ "$mac_addr"x != ""x ] && echo "eth0_Mac_addr: $mac_addr" [ "$ip_addr"x != ""x ] && echo "eth0_IP_addr: $ip_addr" [ "$eth1_mac_addr"x != ""x ] && echo "eth1_Mac_addr: $eth1_mac_addr" [ "$eth1_ip_addr"x != ""x ] && echo "eth1_IP_addr: $eth1_ip_addr" echo "net_list:" echo "$net_list"
FB卡：
在/sys/class/fc_host/下的port_name下
echo "******fb*******" fb=$(lspci|grep Fibre|sed 's/^.*: //g') [ -d "/sys/class/fc_host/" ] && fb_list=$(ls /sys/class/fc_host/) [ "$fb"x != ""x ]&& echo "FB_Card: $fb" for i in $fb_list do fb_port_num=$(cat /sys/class/fc_host/$i/port_name) echo "fb_port_number: $fb_port_num" done
