测试机器的硬件信息

  1. 查看CPU信息(型号)

    • cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c

    return:

    8  Intel(R) Xeon(R) CPU E5410   @ 2.33GHz 
    

(看到有8个逻辑CPU, 也知道了CPU型号)

	- `cat /proc/cpuinfo | grep physical | uniq -c`
	
	return:
	
	```
	4 physical id      : 0 
      4 physical id      : 1 
(说明实际上是两颗4核的CPU) 
- `getconf LONG_BIT `

return:

```
   32 

(说明当前CPU运行在32bit模式下, 但不代表CPU不支持64bit)
```

- `cat /proc/cpuinfo | grep flags | grep ' lm ' | wc -l `

return:

``` 
 8 

(结果大于0, 说明支持64bit计算. lm指long mode, 支持lm则是64bit)
```

- `dmidecode | grep 'Processor Information'`

return:

```
完整看cpu详细信息```
  1. 查看内存信息

    • cat /proc/meminfo

    return:

    返回系统内存信息  
    

3. 	查看机器版本信息
   - `uname -a `
   
   return:
   
   ```
    Linux euis1 2.6.9-55.ELsmp #1 SMP Fri Apr 20 17:03:35 EDT 2007 i686 
i686 i386 GNU/Linux 
(查看当前操作系统内核信息) 
   ```

   - `cat /etc/issue | grep Linux`
   
   return:
   
   ```
Red Hat Enterprise Linux AS release 4 (Nahant Update 5) 
(查看当前操作系统发行版信息)
	```
   
   - `dmidecode | grep "Product Name" `
   
   return:
   
   ```
(查看机器型号)
   ```

	
   - `dmesg | grep -i eth`
   
   return:
   
   ```
(查看网卡信息)
   ```

	
   - `lsb_release -a`
   
   return:
   
   ```
(查看操作系统版本)
   ```
