Pagina legata al server ⚙️ intreccio

Thank you for contributing to this page, collecting info about the website called wikina, served at https://wiki.wikimedia.it/ and running MediaWiki.

Server

The website is served by server ⚙️ intreccio.

Webserver

The frontend webserver is Apache HTTP. Its configuration is published here:

443
https://gitlab.wikimedia.org/repos/wikimedia-it/wmit-infrastructure/-/blob/main/servers/intreccio/conf/apache2/sites-available/it-wikimedia-wiki-ssl.conf
80
https://gitlab.wikimedia.org/repos/wikimedia-it/wmit-infrastructure/-/blob/main/servers/intreccio/conf/apache2/sites-available/it-wikimedia-wiki-txt.conf
Main
https://gitlab.wikimedia.org/repos/wikimedia-it/wmit-infrastructure/-/blob/main/servers/intreccio/conf/apache2/include/it-wikimedia-wiki-main.conf

In short, Apache HTTPd serves static files as-is.

Dynamic files are proxed to the underlying #PHP FPM webserver.

PHP FPM

The backend PHP FPM webserver does not listen to a port but to a filesystem socket. It is here: 

/run/php/php7.3-fpm-wikina.sock

Apache connects to that socket.

MediaWiki

MediaWiki configuration

The MediaWiki configuration is published here:

https://gitlab.wikimedia.org/repos/wikimedia-it/wmit-infrastructure/-/blob/main/servers/intreccio/projects/wikina/LocalSettings-public.php

The public configuration is here on the filesystem: 

/var/www/wikina/LocalSettings-public.php

The secret configuration is on the server itself and it just contains database password, email credentials, upgrade key, and nothing else.

The secret configuration is here on the filesystem: 

nano /var/www/wikina/LocalSettings-secret.php

Systemd unit

There is a systemd unit executing MediaWiki background jobs. Here the unit:

https://gitlab.wikimedia.org/repos/wikimedia-it/wmit-infrastructure/-/blob/main/servers/intreccio/projects/wikina/systemd/wikina-jobs.service

Here its source code:

https://gitlab.wikimedia.org/repos/wikimedia-it/wmit-infrastructure/-/blob/main/servers/intreccio/projects/wikina/scripts/run-jobs.sh

Unix

There is a dedicated Unix user called wmit-wikina:wmit-wikina.

Writable files are assigned to that user.

Non-writable files are assigned to the user root:root.

Extensions

Extensions are deployed here: 

/var/www/wikina/extensions

Then they can be activated from the #MediaWiki configuration.

Database

The database is a local, standard MariaDB installation.

Database name: 

wikina

There is a dedicated username with its credential. It's only stored in the secret #MediaWiki configuration and nowhere else.

Backup

Backup on-site

The database is under a daily on-site backup, executed daily, before midnight. This is the on-site path: 

/var/backups/wmi/intreccio.wikimedia.it/daily/databases/wikina.sql.gz

Backup off-site

The backup is then pushed off-site on this server:

General details:

That copy is then kept for some days, rotated on daily basis. Example location: 

/var/backups/wmi/intreccio.wikimedia.it
/var/backups/wmi.1/intreccio.wikimedia.it
/var/backups/wmi.2/intreccio.wikimedia.it

Etc.

Complete snapshot

There is also a complete daily server snapshot executed from the OpenStack provider, restorable by any "admin" or "superadmin" of this provider:

Don't execute a manual snapshot randomly since it can put the server offline for several minutes.

Don't allocate a server snapshot randomly since it consumes paid resources.
