Linux系统硬盘分区 格式化 挂载的方法
在windows中安装好硬盘之后我们只要分区与格式化就可以了,但在linux中还要多一步硬盘挂载了,下面本文章就全面的介绍linux下安装一块磁盘的过程,其实就包括了硬盘分区 格式化 挂载,希望文章能帮助到各位.
1.添加磁盘,查看磁盘状况 ,代码如下:
[root@db1 /]# fdisk -l Disk /dev/sda: 10.7 GB, 10737418240 bytes 255 heads, 63 sectors/track, 1305 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 151 1305 9277537+ 83 Linux /dev/sda2 1 150 1204843+ 82 Linux swap Partition table entries are not in disk order Disk /dev/sdb: 5368 MB, 5368709120 bytes 255 heads, 63 sectors/track, 652 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System 从查询结果看出,多了一个/dev/sdb的盘.
2.用fdisk 对/dev/sdb 进行分区 ,代码如下:
[root@db1 /]# fdisk /dev/sdb Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-652, default 1): Using default value 1 Last cylinder or + size or +sizeM or +sizeK (1-652, default 652): Using default value 652 Command (m for help): w The partition table has been altered! Calling ioctl() to re- read partition table . Syncing disks. 再次查看分区情况,多出来一个/dev/sdb1 的区,这个1是我们在前面指定的,如果我们指定2,就变成 sdb2了,代码如下:
[root@db1 /]# fdisk -l Disk /dev/sda: 10.7 GB, 10737418240 bytes 255 heads, 63 sectors/track, 1305 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 151 1305 9277537+ 83 Linux /dev/sda2 1 150 1204843+ 82 Linux swap Partition table entries are not in disk order Disk /dev/sdb: 5368 MB, 5368709120 bytes 255 heads, 63 sectors/track, 652 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 1 652 5237158+ 83 Linux [root@db1 /]# 3.格式化 /dev/sdb1 分区, 代码如下:
[root@db1 /]# mkfs -t ext3 /dev/sdb1 mke2fs 1.35 (28-Feb-2004) Filesystem label= OS type: Linux Block size =4096 (log=2) Fragment size =4096 (log=2) 655360 inodes, 1309289 blocks 65464 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=1342177280 40 block groups 32768 blocks per group , 32768 fragments per group 16384 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736 Writing inode tables: done Creating journal (8192 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 30 mounts or 180 days, whichever comes first . Use tune2fs -c or -i to override. 4.创建目录 并将 /dev/sdb1 挂在到该目录下, 代码如下:
[root@db1 /]# ls backup dev initrd media opt sbin sys usr bin etc lib misc proc selinux tftpboot var boot home lost+found mnt root srv tmp
