Linux操作系统 CentOS6.5开机自动挂载硬盘

操作系统 发布时间:2019-03-15 02:18:40

  CentOS是社区企业操作系统,是Linux发行版之一,它是来自于Red Hat Enterprise Linux依照开放源代码规定释出的源代码所编译而成。由于出自同样的源代码,因此有些要求高度稳定性的服务器以CentOS替代商业版的Red Hat Enterprise Linux使用。两者的不同,在于CentOS并不包含封闭源代码软件。

  企业级应用系统的建设,通常将系统和数据分别存储,并建立raid。新装的CentOS6.5,需要挂载数据盘,并且能够系统启动自动挂载该数据盘。

  1、手动挂载磁盘

  查看磁盘分区信息,执行fdisk命令

  [root@tsp-rls-webservice tsp]# fdisk -l

  Disk /dev/sdb: 1476.5 GB, 1476529225728 bytes

  255 heads, 63 sectors/track, 179511 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: 0x0008a3a1

  Device Boot Start End Blocks Id System

  /dev/sdb1 1 179512 1441922048 83 Linux

  Disk /dev/sda: 322.1 GB, 322122547200 bytes

  255 heads, 63 sectors/track, 39162 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: 0x6a5b51c5

  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 39163 314059776 8e Linux LVM

  Disk /dev/mapper/vg_tsprlswebserv-lv_root: 53.7 GB, 53687091200 bytes

  255 heads, 63 sectors/track, 6527 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/mapper/vg_tsprlswebserv-lv_swap: 16.8 GB, 16814964736 bytes

  255 heads, 63 sectors/track, 2044 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/mapper/vg_tsprlswebserv-lv_home: 251.1 GB, 251092008960 bytes

  255 heads, 63 sectors/track, 30526 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

  查看到/dev/sdb1没有挂载,接下来建立挂载点(创建挂载目录),执行mount命令,挂载数据盘。

  [root@tsp-rls-webservice tsp]# mkdir /tsp

  [root@tsp-rls-webservice tsp]# mount /dev/sdb1 /tsp

  2、系统启动,自动挂载数据盘

  查看磁盘UUID信息

  [root@tsp-rls-webservice tsp]# blkid

  /dev/mapper/vg_tsprlswebserv-lv_root: UUID="3dedb8a7-69c5-44d7-b590-e70a0b1b3c9a" TYPE="ext4"

  /dev/sdb1: UUID="e85dd659-bb20-4d12-a8bc-16130efc04ea" TYPE="ext4"

  /dev/sda1: UUID="97f12da1-c972-4508-9028-9b98cde34a34" TYPE="ext4"

  /dev/sda2: UUID="cKJ1xc-8mci-0d89-DNaR-5IAG-2JOv-V1G1q9" TYPE="LVM2_member"

  /dev/mapper/vg_tsprlswebserv-lv_swap: UUID="aa4589df-1d47-4060-a419-9c4432c3bb9a" TYPE="swap"

  /dev/mapper/vg_tsprlswebserv-lv_home: UUID="17a62039-4676-45ce-8eb9-1914e2d4820c" TYPE="ext4"

  编辑系统分区表

  [root@tsp-rls-webservice tsp]# vi /etc/fstab

  添加如下信息:

  UUID=e85dd659-bb20-4d12-a8bc-16130efc04ea /tsp ext4 defaults 1 2

  编辑后的信息如下:

  #

  # /etc/fstab

  # Created by anaconda on Thu Aug 21 17:17:19 2014

  #

  # Accessible filesystems, by reference, are maintained under '/dev/disk'

  # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info

  #

  /dev/mapper/vg_tsprlswebserv-lv_root / ext4 defaults 1 1

  UUID=97f12da1-c972-4508-9028-9b98cde34a34 /boot ext4 defaults 1 2

  UUID=e85dd659-bb20-4d12-a8bc-16130efc04ea /tsp ext4 defaults 1 2

  /dev/mapper/vg_tsprlswebserv-lv_home /home ext4 defaults 1 2

  /dev/mapper/vg_tsprlswebserv-lv_swap swap swap defaults 0 0

  tmpfs /dev/shm tmpfs defaults 0 0

  devpts /dev/pts devpts gid=5,mode=620 0 0

  sysfs /sys sysfs defaults 0 0

  proc /proc proc defaults 0 0

  保存退出;重启系统,确认自动挂载成功。

  以上就是 CentOS6.5开机自动挂载硬盘 的执行命令,希望能满足各位的需求。的小编也会继续努力寻找更好方法,请继续关注我们,谢谢。
