1：获取CPU的信息：
cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
1 AMD Athlon(tm) II X4 640 Processor
1个核心 和cpu的型号
2：查看cpu的运行模式：
[root@localhost ~]# getconf LONG_BIT
64
运行在64bit下 相当于当前系统是64位的
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1.查看已挂载得到磁盘信息
[root@localhost ~]# df -lh
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root
8.5G 2.1G 5.9G 27% /
tmpfs 244M 0 244M 0% /dev/shm
/dev/sda1 485M 29M 431M 7% /boot
2.查看所有分区的信息
[root@localhost ~]# fdisk -l
Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0009b2ff
Device Boot Start End Blocks Id System
/dev/sda1 * 1 64 512000 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 64 1306 9972736 8e Linux LVM
Disk /dev/dm-0: 9168 MB, 9168748544 bytes
255 heads, 63 sectors/track, 1114 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/dm-0 doesn't contain a valid partition table
Disk /dev/dm-1: 1040 MB, 1040187392 bytes
255 heads, 63 sectors/track, 126 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/dm-1 doesn't contain a valid partition table
用cfdisk也可以实现 q退出
3.查看网卡信息
ethtool ethX //查询ethX网口基本设置
ethtool –h //显示ethtool的命令帮助(help)
ethtool –i ethX //查询ethX网口的相关信息
ethtool –d ethX //查询ethX网口注册性信息
ethtool –r ethX //重置ethX网口到自适应模式
ethtool –S ethX //查询ethX网口收发包统计
待续。。。。。。。。。。。。。
