# Setting up the Sliding Sync proxy (optional)
|
|
|
|
**Note**: The sliding-sync proxy is **not required** anymore as it's been replaced with a different method (called Simplified Sliding Sync) which is integrated into newer homeservers by default (**Conduit** homeserver from version `0.6.0` or **Synapse** from version `1.114`). This component and documentation remain here for historical purposes, but **installing this old sliding-sync proxy is generally not recommended anymore**.
|
|
|
|
The playbook can install and configure [sliding-sync](https://github.com/matrix-org/sliding-sync) proxy for you.
|
|
|
|
Sliding Sync is an implementation of [MSC3575](https://github.com/matrix-org/matrix-spec-proposals/blob/kegan/sync-v3/proposals/3575-sync.md) and a prerequisite for running Element X clients ([Element X iOS](https://github.com/element-hq/element-x-ios) and [Element X Android](https://github.com/element-hq/element-x-android)). See the project's [documentation](https://github.com/matrix-org/sliding-sync) to learn more.
|
|
|
|
## Adjusting DNS records (optional)
|
|
|
|
By default, this playbook installs the Sliding Sync proxy on the `matrix.` subdomain, at the `/sliding-sync` path (https://matrix.example.com/sliding-sync). This makes it easy to install it, because it **doesn't require additional DNS records to be set up**. If that's okay, you can skip this section.
|
|
|
|
If you wish to adjust it, see the section [below](#adjusting-the-sliding-sync-proxy-url-optional) for details about DNS configuration.
|
|
|
|
## Adjusting the playbook configuration
|
|
|
|
To enable Sliding Sync proxy, add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file:
|
|
|
|
```yaml
|
|
matrix_sliding_sync_enabled: true
|
|
```
|
|
|
|
### Adjusting the Sliding Sync proxy URL (optional)
|
|
|
|
By tweaking the `matrix_sliding_sync_hostname` and `matrix_sliding_sync_path_prefix` variables, you can easily make the service available at a **different hostname and/or path** than the default one.
|
|
|
|
Example additional configuration for your `vars.yml` file:
|
|
|
|
```yaml
|
|
# Change the default hostname and path prefix
|
|
matrix_sliding_sync_hostname: ss.example.com
|
|
matrix_sliding_sync_path_prefix: /
|
|
```
|
|
|
|
If you've changed the default hostname, you may need to create a CNAME record for the Sliding Sync proxy domain (`ss.example.com`), which targets `matrix.example.com`.
|
|
|
|
When setting, replace `example.com` with your own.
|
|
|
|
## Installing
|
|
|
|
After configuring the playbook and potentially [adjusting your DNS records](#adjusting-dns-records), run the playbook with [playbook tags](playbook-tags.md) as below:
|
|
|
|
<!-- NOTE: let this conservative command run (instead of install-all) to make it clear that failure of the command means something is clearly broken. -->
|
|
```sh
|
|
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
|
|
```
|
|
|
|
The shortcut commands with the [`just` program](just.md) are also available: `just install-all` or `just setup-all`
|
|
|
|
`just install-all` is useful for maintaining your setup quickly ([2x-5x faster](../CHANGELOG.md#2x-5x-performance-improvements-in-playbook-runtime) than `just setup-all`) when its components remain unchanged. If you adjust your `vars.yml` to remove other components, you'd need to run `just setup-all`, or these components will still remain installed. Note these shortcuts run the `ensure-matrix-users-created` tag too.
|
|
|
|
### External databases
|
|
|
|
Please note that, if your setup utilizes an external database, you must also establish configuration for the sliding sync proxy. Alter the defaults below to suit your configuration:
|
|
|
|
```yaml
|
|
matrix_sliding_sync_database_username: 'matrix_sliding_sync'
|
|
matrix_sliding_sync_database_password: ''
|
|
matrix_sliding_sync_database_hostname: ''
|
|
matrix_sliding_sync_database_port: 5432
|
|
matrix_sliding_sync_database_name: 'matrix_sliding_sync'
|
|
```
|
|
|
|
## Usage
|
|
|
|
You **don't need to do anything special** to make use of the Sliding Sync proxy. Simply open your client which supports Sliding Sync (like Element X) and log in.
|
|
|
|
When the Sliding Sync proxy is [installed](#installing), your `/.well-known/matrix/client` file is also updated. A new `org.matrix.msc3575.proxy` section and `url` property are added there and made to point to your Sliding Sync proxy's base URL (e.g. `https://matrix.example.com/sliding-sync`).
|
|
|
|
This allows clients which support Sliding Sync to detect the Sliding Sync proxy's URL and make use of it.
