检测线上服务器的系统硬件信息，包括：ip地址(内网、所有)、远程控制卡IP、cpu信息(核数)、内存、硬盘、机器码、制造商、产品名称等

ip=`ifconfig|awk '{print $$1,$$2}'|grep -e 'Link' -e 'inet addr:'|awk '{if($$2 ~ /Link/){ORS="";print $$1}else if($$1 ~ /inet/){ORS=""",""";split($$2,a,":");print ":" a[2]}}'`
ipfirst=`echo $$ip|awk -F, '{print $$1}'|awk -F: '{print $$NF}'`
ipall=`ip a s | awk -F '[ \t/]+' '/^ *inet /&&$$NF!~/lo/{printf "%s:%s,",$$NF,$$3}' | sed 's/,$$//'`
#CPU类型/主频/核数
cpu=`sed -r 's/[ \t]+/ /g' /proc/cpuinfo | awk -F": +" '/^model name/{a[$$2]++} END{for(i in a) printf "%s (x%s)\n",i,a[i]}'`
#内存每条大小*条数
memory=`dmidecode | grep -A6 '^Memory Device' | sed -r 's/^[ \t]+//' | awk '/^Size.*MB/{a[$$2/1024]++} END{for(i in a) printf "%sx%s,",i,a[i]}' | sed 's/,$$//'`
#硬盘大小，单位GB
disk=`fdisk -l 2>/dev/null | awk '/^Disk/{printf "%.0f+",$$3}' | sed 's/+$$//'`
#服务器机器码
SN=`dmidecode | grep -A6 'System Information' | sed -rn 's/^\s*Serial Number:\s([0-9A-Za-z]+)\s*$$/\1/p'`
#生产厂商
Manufacturer=`dmidecode | grep -A6 'System Information' | sed -rn 's/^\s*Manufacturer:\s+(.+)\s*$$/\1/p'`
#产品名称
Product=`dmidecode | grep -A6 'System Information' | sed -rn 's/^\s*Product Name:\s+(.+)\s*$$/\1/p'`
#远程控制卡IP
drac_ip=`ipmitool -I open lan print 1 | grep "IP Address " | awk -F: '{print $$2}' | sed 's/ //'`
echo "{$$HOSTNAME}" "{$$ipfirst}" "{$$ipall}" "{$$cpu}" "{$$memory}" "{$$disk}" "{$$SN}" "{$$Manufacturer}" "{$$Product}" "{$$drac_ip}"
注意运行脚本之前先执行 /etc/init.d/ipmi start 不然drac_ip会获取不到。
运行结果为:
{web01} {192.168.103.168} {eth0:192.168.103.168} {Intel(R) Xeon(R) CPU X5560 @ 2.80GHz (x16)} {8x2} {3999+299} {BTNKY2X} {Dell Inc.} {PowerEdge R710} {192.168.1.168}
虚拟机（由于无远程控制卡，最后项为空）
{lx_web_s1} {192.168.0.5} {eth0:192.168.0.5,tun0:10.8.0.1} {Intel(R) Core(TM) i5-2430M CPU @ 2.40GHz (x1)} {0.5x1} {21} {} {VMware, Inc.} {VMware Virtual Platform} {}
实现方法很多，若有补充的地方，欢迎大家分享。
