Centos Ubuntu RedOS系统类型下查看系统信息

一、项目背景

公司项目想展示当前部署系统的：操作系统，软件版本、IP、主机名。

二、页面

三、说明

说明点1：查询系统类型及IP实际流程是，程序执行linux命令获取结果信息的过程。

说明点2：查询系统类型命令

hostnamectl | awk -F': +' '/Static hostname|Operating System/ {printf "%s,", $2}' | sed 's/,$//'

说明点3：目前项目支持查询3种不同类型的系统：Centos、Ubuntu、Res OS

说明点4：其中ip、os和hostname是从服务器查询出来的；version是从配置文件或者适配包读取的；

说明点5：IP其实是从网络接口中获取的信息，比如linux执行iFconfig即可获取网络接口信息，在每个接口的输出中，inet 行表示该接口的 IPv4 地址，inet6 行表示 IPv6 地址

CentOS 系统

• 常见命名
  • 传统上使用 ethX（如 eth0, eth1）
  • 新版本（如 CentOS 7 及以上）可能使用 enoX 或 ensX 这样的命名方式。

Ubuntu 系统

• 常见命名:
  • 新版本的 Ubuntu 通常使用 enpX（如 enp0s3, enp0s8）。

Red Hat 系统

• 常见命名:
  • 新版本的 Red Hat 和 Fedora 系统通常使用 ensX（如 ens33, ens160）。

结论：

• 对于 CentOS，你可以检查 eth, eno, 和 ens 开头的接口。
• 对于 Ubuntu，检查 enp 开头的接口。
• 对于 Red Hat 和 Fedora，检查 ens 开头的接口。

这种方式可以确保你能够捕获到常见的网络接口命名，并获取相应的 IPv4 地址。
