    1、远程终端连接

    软件:putty

    输入IP地址,要保存的名字,点击保存

    首次连接,会出现以下提示。单击 是。

    根据提示,输入服务器用户名和密码。密码不会显示在屏幕上。输入完成后回车。 

    格式化和挂载数据盘

    运行 fdisk -l 命令查看数据盘。

     [root@xxxx ~]# fdisk -l
    
     Disk /dev/xvda: 42.9 GB, 42949672960 bytes
     255 heads, 63 sectors/track, 5221 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: 0x00078f9c
    
     Device Boot      Start         End      Blocks   Id  System
     /dev/xvda1   *           1        5222    41940992   83  Linux
    
     Disk /dev/xvdb: 5368 MB, 5368709120 bytes
     255 heads, 63 sectors/track, 652 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

    执行命令进行分区

    fdisk /dev/xvdb

    根据提示,依次输入 n,p,1,两次回车,wq,分区就开始了。

    [root@xxx ~]# fdisk /dev/xvdb
     Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklab            el
     Building a new DOS disklabel with disk identifier 0x33eb5059.
     Changes will remain in memory only, until you decide to write them.
     After that, of course, the previous content won't be recoverable.
    
     Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
    
     WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
          switch off the mode (command 'c') and change display units to
          sectors (command 'u').

    执行 fdisk -l 命令,查看新的分区。新分区 xvdb1 已经创建好。如下面示例中的/dev/xvdb1。

     [root@xxx ~]# fdisk -l
    
     Disk /dev/xvda: 42.9 GB, 42949672960 bytes
     255 heads, 63 sectors/track, 5221 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: 0x00078f9c
    
     Device Boot      Start         End      Blocks   Id  System
     /dev/xvda1   *           1        5222    41940992   83  Linux
    
     Disk /dev/xvdb: 5368 MB, 5368709120 bytes
     255 heads, 63 sectors/track, 652 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: 0x33eb5059
    
     Device Boot      Start         End      Blocks   Id  System
     /dev/xvdb1               1         652     5237158+  83  Linux

    执行下列命令,对新分区进行格式化

     mkfs.ext3 /dev/xvdb1

    执行下列命令写入新分区信息。

    echo '/dev/xvdb1/mnt ext3 defaults 0 0'>> /etc/fstab

    完成后,可以使用 cat /etc/fstab 命令查看。
