== Addresses ==


* dolibarr-test-fr.traulle.net
* dolibarr-test-org.traulle.net


These DN has been choosen to test the distinct vhosts but are not actually binded to public DNS.
=== Apache2 config ===


You <u>MUST</u> edit your <code>/etc/hosts</code> local file (or similar) to point these addresses to IP '''37.59.159.184'''
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.


For Windows based machines, you can use https://hostsfileeditor.com/ for that purpose.
Enable '''proxy '''and '''proxy_http '''modules.


== Replicated minimal VM for tests ==
Add


For the implementation to go smooth, the <code>vmprod1</code> environment has been replicated on a dedicated test VM.

* Linux distro : Ubuntu 16.4.7
  # Redirection pour compatibilite avec ancien forum kunena

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


=== Apache2 config ===
The Logs of the proxy are available into /home/dolibarr/logs/dolibarr_ssl_access_log file and are used by fail2ban rules.


Apache2 virtual hosts config <code>dolibarr.fr.conf</code> and <code>dolibarr.org.conf</code> has been copied from <code>vmprod1</code> (Servername apache directive has just been modified to match names specified in [[#Addresses]]).
== Firewall ==
