The fire server (a.k.a. The Firehouse)¶

Server information¶

OS: Centos 7
Processor: Quad-core AMD Opteron
Memory: 16GB
Disk: 80G

DNS configuration¶

To change the dns record, contact Chalmers NIC <cth-nic@chalmers.se>.

To avoid confusion with the old fire server (fire.cs.chalmers.se), we use the domain frs.cse.chalmers.se for this server.

The current DNS configuration should be something like this:

frs.cse.chalmers.se.    IN      TXT     "UINFO: alt-fire-reporting-system-on-web-frameworks [en]"
frs.cse.chalmers.se.    IN      A       129.16.22.11
*.frs.cse.chalmers.se.  IN      A       129.16.22.11

Which means that any address of the form <something>.frs.cse.chalmers.se will go to our server.

Instances configuration¶

Configuration files are generated by a script in fire-config. See deployment for more information on how it works.

Each fire instance has its own user, a data directory, a systemd service and two nginx virtual servers (one for the app itself and one to serve uploaded files).

For instance, for the course database-vt16 there will be

a user named fire-database-vt16
a directory /srv/courses/database-vt16
a systemd service fire-database-vt16 configured in /etc/systemd/system/fire-database-vt16.service
Two nginx server config, one for https://database-vt16.frs.cse.chalmers.se and one for https://database-vt16-files.frs.cse.chalmers.se, configured in /etc/nginx/conf.d/database-vt16.conf.

Certificates are obtained from Let’s Encrypt which is an automated certification authority. The configuration to generate and renew the certificates automatically is included in the fire-config repository.
