Django Framework Combat: Build a small server operations website (i)

This article will encounter a lot of code, if you want the source code of the small partner, I have already shared the below, want to be able to study the

I have been engaged in Python development for many years, many small partners want to learn about the Web Django framework, I use the Django framework to do a series of practical projects, welcome to subscribe. Welcome to subscribe to the public number: Python from the program Ape to the programmer, or add 4913.08659, code: Cauchy, Code: Cauchy. There is no understanding can be asked in the inside, but also a study of live data platform

Objective

?? Whether it's operations or development or testing, working with Linux servers, common operations such as viewing CPU or memory status, viewing and modifying server time, viewing or modifying server configuration files, viewing or reviewing the system's logs in real time, restarting a process in the server, and so on. If not next to the server, you will typically choose to use remote SSH tools such as Xshell to log on to the server to perform the required operations. If there is a web tool, the tool will be very convenient for the target users to provide services, for development, you can pay more attention to the code itself, for the operation is easy to directly know the state of the server, for testers, improve the efficiency of testing. I had no experience in developing this Django-based Web tool before, and it was all stones, so there were a lot of problems in the development process, and we solved and reached the requirement one after the other, which also brought some code reuse directly. These articles will contain some front-end techniques (WebSocket, Ajax, routing) and some back-end small modules (Paramiko, OpenID, webserver, MySQL), which in turn will derive many small details and methods in the patchwork of these small parts. This article will do a review, although there is a better way to achieve a multi-functional, the technical difficulties involved are not small, but also hope to help the needs of children's shoes.

Content Introduction

The article default reader already has the Django development experience, the article directly skipped the numerous beginner content, directly starts the small project

These functions are actually very simple, like building blocks, the key is to meet and solve the problem is to make the need for children's shoes to take a little detour. The website style is shown in 1 and Figure 2 (this is the main page, there is no landing screen and other features interface):

Usage

?? We need to change the following places to run the website locally.

Server login configuration in Settings:

A private key is required to place the private key under Webtool/webtool:

Modify some of the server paths and command lines in functions:

Conclusion

?? This small project uses a few techniques, but basically it can interact with the server by invoking the Paramiko module and server interaction in Python via the website. Although the function of the site is not many, but the interaction of ideas can be extrapolate write more features pages (such as: CPU, memory warning, etc.), some of the complex server function is best to write a shell script in the server to provide the site background calls, the front-end parts can be found in the Dashgum suitable.
