# python-hwinfo：使用Linux系统工具展示硬件信息概况
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
到目前为止，获取Linux系统硬件信息和配置已经被大部分工具所涵盖，不过也有许多命令可用于相同目的。
|
|||
|
|
|
|||
|
|
而且，一些工具会显示所有硬件组成的详细信息，重置后，只显示特定设备的信息。
|
|||
|
|
|
|||
|
|
在这个系列中, 今天我们讨论一下关于[python-hwinfo][1]， 它是一个展示硬件信息概况和整洁配置的工具之一。
|
|||
|
|
|
|||
|
|
### 什么是python-hwinfo
|
|||
|
|
|
|||
|
|
这是一个通过解析系统工具（例如lspci和dmidecode）的输出，来检查硬件和设备的Python库。
|
|||
|
|
|
|||
|
|
它提供了一个简单的命令行工具，可以用来检查本地，远程和捕获到的主机。用sudo运行命令以获得最大的信息。
|
|||
|
|
|
|||
|
|
另外，你可以提供服务器IP或者主机名，用户名和密码，在远程的服务器上执行它。当然你也可以使用这个工具查看其它工具捕获的输出（例如demidecode输出的'dmidecode.out'，/proc/cpuinfo输出的'cpuinfo'，lspci -nnm输出的'lspci-nnm.out'）。

### Linux上如何安装python-hwinfo
|
|||
|
|
|
|||
|
|
在绝大多数Linux发行版，都可以通过pip包安装。为了安装python-hwinfo， 确保你的系统已经有python和python-pip包作为先决条件。
|
|||
|
|
|
|||
|
|
pip是Python附带的一个包管理工具，在Linux上安装Python包的推荐工具之一。
|
|||
|
|
|
|||
|
|
在**`Debian/Ubuntu`**平台，使用[APT-GET 命令][7] 或者 [APT 命令][8] 安装pip。
|
|||
|
|
```
|
|||
|
|
$ sudo apt install python-pip
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
在**`RHEL/CentOS`**平台，使用[YUM 命令][9]安装pip。
|
|||
|
|
```
|
|||
|
|
$ sudo yum install python-pip python-devel
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
在**`Fedora`**平台，使用[DNF 命令][10]安装pip。
|
|||
|
|
```
|
|||
|
|
$ sudo dnf install python-pip
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
在**`Arch Linux`**平台，使用[Pacman 命令][11]安装pip。
|
|||
|
|
```
|
|||
|
|
$ sudo pacman -S python-pip
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
在**`openSUSE`**平台，使用[Zypper 命令][12]安装pip。
|
|||
|
|
```
|
|||
|
|
$ sudo zypper python-pip
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
最后，执行下面的pip命令安装python-hwinfo。
|
|||
|
|
```
|
|||
|
|
$ sudo pip install python-hwinfo
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 怎么使用python-hwinfo在本地机器
|
|||
|
|
|
|||
|
|
执行下面的命令，检查本地机器现有的硬件。输出很清楚和整洁，这是我在其他命令中没有看到的。
|
|||
|
|
|
|||
|
|
它的输出分为了五类。
|
|||
|
|
|
|||
|
|
* **`Bios Info:`** bios供应商名称，系统产品名称， 系统序列号，系统唯一标识符，系统制造商，bios发布日期和bios版本。
|
|||
|
|
* **`CPU Info:`** 处理器编号，供应商ID，cpu系列代号，型号，制作更新版本，型号名称，cpu主频。
|
|||
|
|
* **`Ethernet Controller Info:`** 供应商名称，供应商ID，设备名称，设备ID，子供应商名称，子供应商ID，子设备名称，子设备ID。
|
|||
|

|
|||
|
|
* **`GPU Info:`** 供应商名称，供应商ID，设备名称，设备ID，子供应商名称，子供应商ID，子设备名称，子设备ID。

|||
|
|
$ hwinfo -m x.x.x.x -u root -p password
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 如何使用python-hwinfo读取捕获的输出
|
|||
|
|
|
|||
|
|
执行下面的命令，检查本地机器现有的硬件。输出很清楚和整洁，这是我在其他命令中没有看到的。
|
|||
|
|
```
|
|||
|
|
$ hwinfo -f [Path to file]
|
|||
