Using your own webserver, instead of this playbook's nginx proxy (optional, advanced)

By default, this playbook installs its own nginx webserver (in a Docker container) which listens on ports 80 and 443. If that's alright, you can skip this.

If you don't want this playbook's nginx webserver to take over your server's 80/443 ports like that, and you'd like to use your own webserver (be it nginx, Apache, Varnish Cache, etc.), you can.

All it takes is:

making sure your web server user (something like http, apache, www-data, nginx) is part of the matrix group. You should run something like this: usermod -a -G matrix nginx
editing your configuration file (inventory/matrix.<your-domain>/vars.yml):

matrix_nginx_proxy_enabled: false

Note: even if you do this, in order to install, this playbook still expects port 80 to be available. Please manually stop your other webserver while installing. You can start it back again afterwards.

If your own webserver is nginx, you can most likely directly use the config files installed by this playbook at: /matrix/nginx-proxy/conf.d. Just include them in your nginx.conf like this: include /matrix/nginx-proxy/conf.d/*.conf;

If your own webserver is not nginx, you can still take a look at the sample files in /matrix/nginx-proxy/conf.d, and:

ensure you set up (separate) vhosts that proxy for both Riot (localhost:8765) and Matrix Synapse (localhost:8008)
ensure that the /.well-known/acme-challenge location for each "port=80 vhost" gets proxied to http://localhost:2402 (controlled by matrix_ssl_certbot_standalone_http_port) for automated SSL renewal to work
ensure that you restart/reload your webserver once in a while, so that renewed SSL certificates would take effect (once a month should be enough)

Apache2 sample configuration files

Create a new apache configuration file named 000-matrix-ssl.conf and enable it.

Enable required apache2 modules

Reload apache
```
 systemctl restart apache2
```

Notes: port 8448 does not get proxied and is left available for the homeserver federation api.
