With most people on Synapse v0.99+ and Synapse v1.0 now available, we should no longer try to be backward compatible with Synapse 0.34, because this just complicates the instructions for no good reason.

# 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](howto-server-delegation.md), there are 2 different ways to set up such delegation:
|
|
|
|
- either by serving a `https://<your-domain>/.well-known/matrix/server` file (from the base domain!)
|
|
- or by using a `_matrix._tcp` DNS SRV record (don't confuse this with the `_matrix-identity._tcp` SRV 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)](howto-server-delegation.md#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.
|
|
|
|
|
|
## General outline of DNS settings you need to do
|
|
|
|
| Type | Host | Priority | Weight | Port | Target |
|
|
| ----- | ----------------------- | -------- | ------ | ---- | ---------------------- |
|
|
| A | `matrix` | - | - | - | `matrix-server-IP` |
|
|
| CNAME | `riot` | - | - | - | `matrix.<your-domain>` |
|
|
| CNAME | `dimension` | - | - | - | `matrix.<your-domain>` |
|
|
| SRV | `_matrix-identity._tcp` | 10 | 0 | 443 | `matrix.<your-domain>` |
|
|
|
|
|
|
## Subdomains setup
|
|
|
|
As the table above illustrates, you need to create 2 subdomains (`matrix.<your-domain>` and `riot.<your-domain>`) and point both of them to your new server's IP address (DNS `A` record or `CNAME` record is fine).
|
|
|
|
The `riot.<your-domain>` subdomain is necessary, because this playbook installs the Riot web client for you.
|
|
If you'd rather instruct the playbook not to install Riot (`matrix_riot_web_enabled: false` when [Configuring the playbook](configuring-playbook.md) later), feel free to skip the `riot.<your-domain>` DNS record.
|
|
|
|
The `dimension.<your-domain>` subdomain may be necessary, because this playbook could install the [Dimension integrations manager](http://dimension.t2bot.io/) 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](configuring-playbook-dimension.md) later). If you do not wish to set up Dimension, feel free to skip the `dimension.<your-domain>` DNS record.
|
|
|
|
|
|
## `_matrix-identity._tcp` SRV record setup
|
|
|
|
To make the [mxisd](https://github.com/kamax-io/mxisd) Identity Server (which this playbook installs for you) be authoritative for your domain name, set up one more 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)
|
|
|
|
|
|
When you're done with the DNS configuration and ready to proceed, continue with [Configuring this Ansible playbook](configuring-playbook.md).
