⚙️ intreccioThank 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:
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:
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:
Here its source code:
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.
