Linux System directory Architecture

/bin directory: Executable binary (the command we're talking about: CP ls ... ), all users have the right to execute.

/boot directory: The boot directory, all the files required to boot the entire operating system are in this directory, the most important of which is the Vmlinux file, which is what we call the Linux kernel.

/dev Directory: All hardware devices, such as hard drives, network cards, etc.

/etc Directory: Almost all configuration files related to the operating system

/home directory: House directory, saving the user's private data. All users of the operating system will have a corresponding folder in the/home directory. (The root user's home directory is very special, directly in the root directory of the root folder).

/lib directory: All library files required for Linux operating system programs to end with. So

/MNT: Normal mount Directory, general Mount will be mounted in this directory

/media: Also mount the directory, some devices (U disk, CD-ROM) may be automatically mounted in the directory

/OPT: Often used to install large software (such as Oracle)

/proc: Real-time information of the operating system, does not exist on the hard disk, only exists in memory, is a virtual folder.

/sbin: Executable binary, which commands only the Superuser can execute.

/sys: System's underlying hardware information

/tmp: The temporary directory, all the information in this directory is temporary, the contents of a certain period of time will be automatically cleared.

/usr: Save our installed application, usually the application software is installed by default in this directory, the large software is installed in the/OPT directory by default.

/var: something that is constantly changing, such as log information.

The Linux system requires only two partitions to be created during installation:

Swap partition--swap partition, is actually what we say virtual memory, generally we own experimental application 4G can be

/root partition, which is as large as possible in available free capacity.
