About the management of the uwsgi server

Preface

Using Django to develop projects is great, but deployment is quite troublesome. When using the Uwsgi server, every time the code is modified, the server needs to be restarted for the changes to take effect. Moreover, restarting the Uwsgi server is also quite a hassle.

After reviewing the official documentation, it's best to install Uwsgi inside a venv virtual environment. This way, it's easier to differentiate when running ps aux.

View uwsgi processes

ps -aux | grep uwsgi

Terminate the original uwsgi process

kill -9 27543

Conclusion

This is still cumbersome—you have to manually locate the uwsgi process and terminate it. Next, I should look for a more convenient approach, such as adding uwsgi as a service for systemctl to manage, though the official documentation advises against doing this?

Supplementary

There are a few other ways to simplify the management of the uwsgi server.

• Using Supervisor to manage the uwsgi service

Supervisor (http://supervisord.org/) is a client/server service developed in Python. It's a process management tool for Linux/Unix systems and does not support Windows. It can conveniently monitor, start, stop, and restart one or multiple processes. When a process managed by Supervisor is unexpectedly killed, the supervisor detects the process death and automatically restarts it, providing a convenient automatic process recovery feature without needing to write shell scripts yourself.

• Emperor mode

uWSGI can run in 'emperor' mode. In this mode, it monitors a directory of uWSGI configuration files and generates an instance ('vassal') for each configuration file it finds. Whenever a configuration file is modified, the emperor will automatically restart the vassal.
