If you are struggling with below error while deploying Django on VPS, this post may help and save you hours for MariaDB Troubleshoot.

  • Did you install mysqlclient or MySQL-python?
  • OSError: mysql_config not found
  • ModuleNotFoundError: No module named ‘ConfigParser’

This is my 2nd times try out Django with MariaDB. The 1st one went smoothly. Couple of searches and I find that I only need to add a simple line into “activate” file of Python VirtualEnv

2nd time didn’t go right, when running “python manage.py migrate“, I got “Did you install mysqlclient or MySQL-python?“. Continue trying to run “pip install mysqlclient“, I got “OSError: mysql_config not found“, and sometimes “ModuleNotFoundError: No module named ‘ConfigParser‘”

MariaDB Troubleshoot

I tried and installed many things and not quite sure which one resolved the issue. I do believe below helped me out

“yum install mariadb-devel”

After running above command, I was able to “pip install mysqlclient” and “python manage.py migrate”

Believe me or not, there are hundred ways to setup web server. I searched and tried many of them on a VPS with 512MB of RAM. Most of them had issue with database, MySQL or MariaDB was die again and again. This one has worked for me for more than a year: CNMP (Centos 7 + NGINX + MariaDB + PHP 7).

Grab a VPS

I’ve used DigitalOcean as VPS provider for a while. Linode is one of my next try since its same price but double RAM. If you have any experience with other VPS providers, please share.

Basic Setup

Setup Firewall

Timezones Configuration

Create a Swap File

This section doesn’t apply for VPS at Linode since they have option to create SWAP file at VPS configuration.

FLUSH PRIVILEGES;

Wrap it up

That’s it. I know it’s too much if you are newbie to VPS but I hope it is helpful for you. This is how I setup Developer’s Notes (I didn’t cover ssl part yet). Leave a comment or feedback right below.
