脚本-批量收集服务器信息

本脚本用于一键获取服务器的信息(cpu, mem, 磁盘分组, 序列号等)

脚本依赖常用命令ls, cat, df, ip, lscpu, hostname, uname, free, dmidecode, ethtool等, 可能dmidocode和ethtool有些机器上没有, 需要安装一下, 其他的命令, 基本上都是linux服务器自带的

脚本

内容如下

echo "File: $tmpfile"
➜  ~

运行

bash get-system-info.sh 

跑完后,会产生文件/tmp/tmp-server-info.csv, 直接用excel打开,调整下格式就好

效果

最终的预览效果如下
