Personal technology Blog--linux Server configuration and Flask framework

This time the software engineering practice, I am responsible for our group backstage service construction, I chose the bandwagon server, installs the Debian Gnu/linux, the backend service is uses the Python flask frame.

Log on to the remote server locally

Logging on to the remote server locally is now mostly ssh.

Secure Shell (abbreviated as SSH), developed by the IETF Network Working Group, which provides a secure transport and usage environment for the shell (shell) on the computer by creating a security protocol based on the application layer and transport layer.

The SSH tools on Windows are PUTTY,SECURECRT and Xshell and so on, I chose Xshell. The general server provider will tell you the initial SSH port and root password, and you can log in to the server with SSH.

Open Xshell, click New in the upper left corner of the session.

In the host box, write the IP address of the server, port number to write the port number of SSH,

Click on user authentication, fill in the user name and password, user name to write root, password to write the initial root password (you can also create a user login).

Click OK, then connect, after success as.

Next, you can operate the server with various Linux commands.

Flask Frame

Flask is a lightweight Web application framework written using Python. Based on the Werkzeug Wsgi Toolbox and the Jinja2 template engine. Flask uses BSD licensing. Flask is called microframework because it requires only dozens of lines of code to write a Web application. Take "Hello World" as an example.

from flask import Flaskapp = Flask(__name__)@app.route('/')def hello_world():    return 'Hello World!'if __name__ == '__main__':    app.run()
