Configuring your DNS server
To set up Matrix on your domain, you'd need to do some DNS configuration.
To use an identifier like @<username>:<your-domain>, you don't actually need
to install anything on the actual <your-domain> server.
You do, however need to instruct the Matrix network that Matrix services for <your-domain> are delegated
over to matrix.<your-domain>.
As we discuss in Server Delegation, there are 2 different ways to set up such delegation:
- either by serving a
https://<your-domain>/.well-known/matrix/serverfile (from the base domain!) - or by using a
_matrix._tcpDNS SRV record (don't confuse this with the_matrix-identity._tcpSRV record described below)
This playbook mostly discusses the well-known file method, because it's easier to manage with regard to certificates. If you decide to go with the alternative method (Server Delegation via a DNS SRV record (advanced)), please be aware that the general flow that this playbook guides you through may not match what you need to do.
DNS settings for services enabled by default
| Type | Host | Priority | Weight | Port | Target |
|---|---|---|---|---|---|
| A | matrix |
- | - | - | matrix-server-IP |
| CNAME | element |
- | - | - | matrix.<your-domain> |
Be mindful as to how long it will take for the DNS records to propagate.
If you are using Cloudflare DNS, make sure to disable the proxy and set all records to DNS only. Otherwise, fetching certificates will fail.
DNS settings for optional services/features
| Type | Host | Priority | Weight | Port | Target |
|---|---|---|---|---|---|
| SRV | _matrix-identity._tcp |
10 | 0 | 443 | matrix.<your-domain> |
| CNAME | dimension |
- | - | - | matrix.<your-domain> |
| CNAME | jitsi |
- | - | - | matrix.<your-domain> |
| CNAME | stats |
- | - | - | matrix.<your-domain> |
| CNAME | goneb |
- | - | - | matrix.<your-domain> |
| CNAME | sygnal |
- | - | - | matrix.<your-domain> |
| CNAME | ntfy |
- | - | - | matrix.<your-domain> |
| CNAME | hydrogen |
- | - | - | matrix.<your-domain> |
| CNAME | cinny |
- | - | - | matrix.<your-domain> |
| CNAME | buscarron |
- | - | - | matrix.<your-domain> |
Subdomains setup
As the table above illustrates, you need to create 2 subdomains (matrix.<your-domain> and element.<your-domain>) and point both of them to your new server's IP address (DNS A record or CNAME record is fine).
The element.<your-domain> subdomain may be necessary, because this playbook installs the Element web client for you.
If you'd rather instruct the playbook not to install Element (matrix_client_element_enabled: false when Configuring the playbook later), feel free to skip the element.<your-domain> DNS record.
The dimension.<your-domain> subdomain may be necessary, because this playbook could install the Dimension integrations manager for you. Dimension installation is disabled by default, because it's only possible to install it after the other Matrix services are working (see Setting up Dimension later). If you do not wish to set up Dimension, feel free to skip the dimension.<your-domain> DNS record.
The jitsi.<your-domain> subdomain may be necessary, because this playbook could install the Jitsi video-conferencing platform for you. Jitsi installation is disabled by default, because it may be heavy and is not a core required component. To learn how to install it, see our Jitsi guide. If you do not wish to set up Jitsi, feel free to skip the jitsi.<your-domain> DNS record.
The stats.<your-domain> subdomain may be necessary, because this playbook could install Grafana and setup performance metrics for you. Grafana installation is disabled by default, it is not a core required component. To learn how to install it, see our metrics and graphs guide. If you do not wish to set up Grafana, feel free to skip the stats.<your-domain> DNS record. It is possible to install Prometheus without installing Grafana, this would also not require the stats.<your-domain> subdomain.
The goneb.<your-domain> subdomain may be necessary, because this playbook could install the Go-NEB bot. The installation of Go-NEB is disabled by default, it is not a core required component. To learn how to install it, see our configuring Go-NEB guide. If you do not wish to set up Go-NEB, feel free to skip the goneb.<your-domain> DNS record.
The sygnal.<your-domain> subdomain may be necessary, because this playbook could install the Sygnal push gateway. The installation of Sygnal is disabled by default, it is not a core required component. To learn how to install it, see our configuring Sygnal guide. If you do not wish to set up Sygnal (you probably don't, unless you're also developing/building your own Matrix apps), feel free to skip the sygnal.<your-domain> DNS record.
The ntfy.<your-domain> subdomain may be necessary, because this playbook could install the ntfy UnifiedPush-compatible push notifications server. The installation of ntfy is disabled by default, it is not a core required component. To learn how to install it, see our configuring ntfy guide. If you do not wish to set up ntfy, feel free to skip the ntfy.<your-domain> DNS record.
The hydrogen.<your-domain> subdomain may be necessary, because this playbook could install the Hydrogen web client. The installation of Hydrogen is disabled by default, it is not a core required component. To learn how to install it, see our configuring Hydrogen guide. If you do not wish to set up Hydrogen, feel free to skip the hydrogen.<your-domain> DNS record.
The cinny.<your-domain> subdomain may be necessary, because this playbook could install the Cinny web client. The installation of cinny is disabled by default, it is not a core required component. To learn how to install it, see our configuring cinny guide. If you do not wish to set up cinny, feel free to skip the cinny.<your-domain> DNS record.
The buscarron.<your-domain> subdomain may be necessary, because this playbook could install the buscarron bot. The installation of buscarron is disabled by default, it is not a core required component. To learn how to install it, see our configuring buscarron guide. If you do not wish to set up buscarron, feel free to skip the buscarron.<your-domain> DNS record.
_matrix-identity._tcp SRV record setup
To make the ma1sd Identity Server (which this playbook may optionally install for you) enable its federation features, set up an SRV record that looks like this:
- Name:
_matrix-identity._tcp(use this text as-is) - Content:
10 0 443 matrix.<your-domain>(replace<your-domain>with your own)
This is an optional feature for the optionally-installed ma1sd service. See ma1sd's documentation for information on the privacy implications of setting up this SRV record.
Note: This _matrix-identity._tcp SRV record for the identity server is different from the _matrix._tcp that can be used for Synapse delegation. See howto-server-delegation.md for more information about delegation.
When you're done with the DNS configuration and ready to proceed, continue with Getting the playbook.
