After moving an application to a PaaS platform, intermittent 502 errors occur due to Nginx’s retry behavior, HTTP/1.1 connection reuse, and a mismatch between Ingress and uwsgi protocols, which can be diagnosed through error statistics and packet capture.
This tutorial walks beginners through deploying a Django application on a fresh Linux server using the BT (BaoTa) panel, covering security‑group port opening, software installation, Python environment setup, uWSGI and Nginx configuration, static file handling, and common troubleshooting steps.
After moving an application to a PaaS platform, intermittent 502 errors appear mainly on POST requests; the article analyzes Nginx retry behavior, Ingress‑uwsgi protocol mismatches, packet‑capture findings, and provides a configuration fix to resolve the issue.
This article details the design, architecture, key technologies, and deployment of Xiaosi, an AI‑powered intelligent customer service chatbot built on the internal IM platform, highlighting its problem‑diagnosis accuracy, manpower savings, adapter mechanism, high‑availability backend, and practical use cases.
This article explains the origins, principles, and interactions of CGI, FastCGI, PHP‑FPM, WSGI, uWSGI, and ASGI, detailing how they enable dynamic Python web applications to communicate with web servers such as Nginx and Apache while addressing performance and concurrency concerns.
After moving an application to a PaaS platform, intermittent 502 errors occur, seemingly only for POST requests, but the root cause lies in Nginx‑Ingress and uwsgi HTTP version mismatches, connection reuse, and retry behavior, which can be diagnosed through traffic analysis and configuration changes.
After migrating to a PaaS platform, intermittent 502 errors appeared on both GET and POST requests, and a detailed analysis of Nginx retry behavior, Ingress HTTP version settings, and uWSGI incompatibility reveals the root cause and a configuration fix.
This guide walks through setting up a CentOS 7 server, creating a non‑root user, installing Python 3, MySQL, and required packages, configuring a Django project, and deploying it with uWSGI behind Nginx for production use.
