Linux directory structure

All directories are under the root

directory Structure and disk separation

Directory hierarchy:

What file data should be placed in each directory in the first layer "/" directory

For example:/etc directory decentralization system configuration file

/bin and/sbin placing programs and system commands

The second tier is defined for both the/USR and/var directories.

For example: Place system log files under/var/log, etc.

Tip: The/var partition is separate and the hard drive is large enough. There are monitoring, the remaining 20% alarms.

/dev/Equipment Catalog

/etc/system Configuration and service configuration file, start command directory

/proc virtual directory showing kernel and process information

/tmp Temp file directory, public toilet, living room

/home directory for ordinary users

/root Administrator Home Directory

/var changes the directory, usually the log file, the cache directory.

/usr user program, and directories for data, help files, binary commands, etc.

Directories for/bin and/sbin and/usr/sbin/user commands.

/proc operating system runtime, process information and kernel information (such as CPU, hard disk partition, memory information, etc.) are stored here

Cat/proc/meminfo Memory Information

Cat/proc/cpuinfo CPU

Cat/proc/mounts Mount

CAT/PROC/LOADAVG load
