[05-002] Linux directory structure introduced and remotely operated vehicle: Xshell, Xftp, WinSCP, etc.

1. Directory structure

1.1 Basic Introduction

Linux file system is a tree directory structure laminar type, the uppermost root directory "/" directory and then the next and then re-create other directories.
In the Linux world, everything is a file.

1.2 Specific configuration (focus bold)

1. / bin (/ usr / bin, / usr / local / bin) is a binary acronym, This directory is the most commonly used commands;
2. / sbin (/ usr / sbin, / usr / local / sbin) Super User S is meant here is the storage hypervisor system administrators;
3. / home store home directories ordinary users, each user in Linux has its own directory, the directory name to the general user account name;
4. / root of the directory for the system administrator, also called super-user privileges group directory;
5. / boot storage are some of the core Linux startup files, including some linked files and image files;
6. / Proc a virtual directory, which is the system memory map, access the directory to obtain system information;
7. Abbreviations / srv service, the directory to store some of the data service started to be extracted;
8. / Sys This is a big change Linux2.6 kernel, the 2.6 kernel a file that appears in the installation directory;
9. / Tmp This directory is used to store temporary files;
10. / Dev similar to the Device Manager under Windows, all the hardware is stored in the form of a file;
11. / Media Linux will automatically identify some devices, such as U disk, CD-ROM, etc., after identification, the device may be mounted to this directory;
12. / mnt system provides this directory is to enable users to temporarily mount other file systems, we can use an external memory mounted on / mnt /
13. / Opt This is for the host software to install the placing of a directory, such as installing mysql database to this, the default is empty;
14. / usr / local This is another installation directory to host additional installed software, usually installed by compiling source code of the program;
15. / var This directory contains the ever-expanding stuff, will often be used to modify the directory in this directory, including log files about her;
16. / Selinux [security-enhanced linux] 360 a secure subsystem control program can only have access to specific files.

1.3 summary

1. Linux directory has one and only one root directory;
2. Linux content of each directory store is planned, without misplacing files;
3. Linux file management in the form of our equipment, so the Linux system, everything is a file;
4. What is stored under various file directory Linux, we must have an understanding;
5. After learning, the mind should have a directory tree.

2. remotely operated vehicle (similar)

2.1 Xshell5

Action: to access a remote server, the remote terminal under the control of different systems in the Windows interface.
Pros: the best use of remote login software, speed and smooth, perfect solution Chinese garbage problem, support Telnet protocol SSH1, SSH2, Windows platform.
Remote premise: Linux SSHD must be enabled service that listens port 22, so as to remote access.

2.2 xftp

Role: is a powerful Windows-based platform, SFTP, FTP file transfer software. Secure file transfer between Windows and Linux.

1.3 Xftp solve the garbage problem
