Apache2 config

Forums are available on entry URL: https://www.dolibarr.org/forum, https://www.dolibarr.fr/forum, https://www.dolibarr.de/forum but behind, it is discourse.

Enable proxy and proxy_http modules.

Add

The apache proxy redirect HTTP including /forum/ in URL to the port the docker nginx server run.

The Logs of the proxy are available into /home/dolibarr/logs/dolibarr_ssl_access_log file and are used by fail2ban rules.

Firewall

TODO Utiliser ufw


Backup

Backup of discourse instance is done into directories /mnt/sdb1/backup/discourses

MySQL/MariaDB Databases

Database names and users has been preserved (same users, same database names and same credentials has been created on test VM).

Databases for French and International websites has been dumped and restored on test VM.

Docker

Installed following the Docker docs : https://docs.docker.com/install/linux/docker-ce/ubuntu/#install-docker-engine---community-1

Tests for dolibarr.de migration

  • Retrieve test VM backup
  • Update packages (apt)
  • Upgrade db to postgres12 (data container)
  • rebuild web_only container tu upgrade to same discourse version as prod

Upgrade the web container

From : https://meta.discourse.org/t/faster-rebuilds/40341/13 

cd /var/discourse
sudo git pull
sudo ./launcher bootstrap web_only
sudo ./launcher destroy web_only
sudo ./launcher start web_only

Upgrade the data container

See 

cd /var/discourse
sudo ./launcher stop web_only
sudo ./launcher stop data
# twice is not a typo but on purpose
sudo ./launcher rebuild data
sudo ./launcher rebuild data
sudo ./launcher rebuild web_only
