Troubleshooting Guide for Setting Up the HttpRunnerManager Environment

Before building the HttpRunnerManager environment the author encountered many pitfalls; this article shares those problems and their solutions to help others facing the same issues.

The environment requires a Python runtime (preferably version 3.0 or higher), a MySQL server, and the RabbitMQ message broker. After installing RabbitMQ, Erlang must be installed with a version compatible with the chosen RabbitMQ release.

1. Version selection : Use Python 3+ because Django 2.x (or higher) is needed; older Django 1.x versions may cause compatibility problems.

2. RabbitMQ web‑admin login issue : The default guest user can only log in from localhost. Create a new user with appropriate permissions and use it to log in.

3. Django version : Install a newer Django version, e.g., pip install django==2.1.1, to avoid incompatibility with the author's code.

4. djcelery installation : The djcelery package may be missing; install it via pip install django-celery.

5. mysqlclient installation : Install Visual C++ build tools or download a matching .whl file from https://www.lfd.uci.edu/~gohlke/pythonlibs/ and install it with pip install mysqlclient‑…‑cp38‑cp38‑win_amd64.whl (example).

6. Database character‑set issue : MySQL must use UTF‑8 encoding. Either set the character set when creating the database, or modify an existing database with:

SHOW VARIABLES LIKE '%char%';

SET character_set_database=utf8;

7. Remote MySQL access problem : By default MySQL restricts remote connections. Update the user table to allow any host and flush privileges:

mysql -u root -p

USE mysql;

UPDATE user SET host='%' WHERE user='root';

SELECT host, user FROM user;

FLUSH PRIVILEGES;

8. yaml module installation : If the yaml module is missing, install it with pip install pyyaml.

After following these steps the HttpRunnerManager environment should be fully functional.
