Linux disk and File system management (what you need to know to install Linux)

I installed the CentOs6.5 version, because I began to study completely self-taught, so when the installation of nothing to understand, now just this semester to open this course and I have been following the teaching video learning, so first 1.1 points of summing up the study. I personally think that at the time of installation know each partition, the meaning of the mount is relatively good, so I first summarize the disk and file system definition, to facilitate understanding and installation.

Linux on the partition is not like Windows on the C-drive, D-disk, e-disk, and so on, Linux partition but like an upside down tree, one-level partition, all devices in Linux appears to be file devices.

1, at the beginning of the time you will see ext2 or ext3. In fact, ext2 refers to the file system. The regular file system for Linux is ext2.

2, mount point: The load point must be a directory, cannot be a file, the directory to enter the file system entrance, in fact, to enter the file system entrance.

Then the next task is to partition, in the partition also need to mount point, is the system list of the drop-down list of their own choice, the following describes the meaning of a partition mount point.

Partition mount point:

/root Partition

/USR Application storage location

The parent directory of the/home user host Directory

/var store temporary files

/boot store boot file 128M is enough.

Understanding the mount point should know why the Linux partition is like an upside down tree, then each layer will need a mount point to enter the file system.

3, after the partition is finished the next operation is formatted, why also need to format, because each operating system file attributes/permissions are not the same, in order to store the data required for these files, so you need to format the partition to become the operating system can take advantage of the file format system.

The following assigns a linuxf the meaning of the partition naming.

This naming only needs to understand, because later to learn is the command line, sometimes open the partition device, and so on, to understand the meaning of its name.
