# Configure Nginx (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.
|
|
|
|
|
|
## Using Nginx status
|
|
|
|
This will serve a statuspage to the hosting machine only. Useful for monitoring software like [longview](https://www.linode.com/docs/platform/longview/longview-app-for-nginx/)
|
|
|
|
```yaml
|
|
matrix_nginx_proxy_proxy_matrix_nginx_status_enabled: true
|
|
```
|
|
|
|
This will serve the status page under the following addresses:
|
|
- `http://matrix.DOMAIN/nginx_status` (using HTTP)
|
|
- `https://matrix.DOMAIN/nginx_status` (using HTTPS)
|
|
|
|
By default, if ```matrix_nginx_proxy_nginx_status_enabled``` is enabled, access to the status page would be allowed from the local IP address of the server. If you wish to allow access from other IP addresses, you can provide them as a list:
|
|
|
|
```yaml
|
|
matrix_nginx_proxy_proxy_matrix_nginx_status_allowed_addresses:
|
|
- 8.8.8.8
|
|
- 1.1.1.1
|
|
```
|
|
|
|
## Adjusting SSL in your server
|
|
|
|
You can adjust how the SSL is served by the nginx server using the `matrix_nginx_proxy_ssl_preset` variable. We support a few presets, based on the Mozilla Server Side TLS
|
|
Recommended configurations. These presets influence the TLS Protocol, the SSL Cipher Suites and the `ssl_prefer_server_ciphers` variable of nginx.
|
|
Possible values are:
|
|
|
|
- `"modern"` - For Modern clients that support TLS 1.3, with no need for backwards compatibility
|
|
- `"intermediate"` (**default**) - Recommended configuration for a general-purpose server
|
|
- `"old"` - Services accessed by very old clients or libraries, such as Internet Explorer 8 (Windows XP), Java 6, or OpenSSL 0.9.8
|
|
|
|
**Be really carefull when setting it to `"modern"`**. This could break comunication with other Matrix servers, limiting your federation posibilities.
|
|
|
|
Besides changing the preset (`matrix_nginx_proxy_ssl_preset`), you can also directly override these 3 variables:
|
|
|
|
- `matrix_nginx_proxy_ssl_protocols`: for specifying the supported TLS protocols.
|
|
- `matrix_nginx_proxy_ssl_prefer_server_ciphers`: for specifying if the server or the client choice when negotiating the cipher. It can set to `on` or `off`.
|
|
- `matrix_nginx_proxy_ssl_ciphers`: for specifying the SSL Cipher suites used by nginx.
|
|
|
|
For more information about these variables, check the `roles/matrix-nginx-proxy/defaults/main.yml` file.
|
|
|
|
## Synapse + OpenID Connect for Single-Sign-On
|
|
|
|
If you want to use OpenID Connect as an SSO provider (as per the [Synapse OpenID docs](https://github.com/matrix-org/synapse/blob/develop/docs/openid.md)), you need to use the following configuration (in your `vars.yml` file) to instruct nginx to forward `/_synapse/oidc` to Synapse:
|
|
|
|
```yaml
|
|
matrix_nginx_proxy_proxy_matrix_client_api_forwarded_location_synapse_oidc_api_enabled: true
|
|
```
|
|
|
|
## Disable Nginx access logs
|
|
|
|
This will disable the access logging for nginx.
|
|
|
|
```yaml
|
|
matrix_nginx_proxy_access_log_enabled: false
|
|
```
|
|
|
|
## Additional configuration
|
|
|
|
This playbook also allows for additional configuration to be applied to the nginx server.
|
|
|
|
If you want this playbook to obtain and renew certificates for other domains, then you can set the `matrix_ssl_additional_domains_to_obtain_certificates_for` variable. Make sure that you have set the DNS configuration for the domains you want to include to point at your server.
|
|
|
|
```yaml
|
|
matrix_ssl_additional_domains_to_obtain_certificates_for:
|
|
- domain.one.example
|
|
- domain.two.example
|
|
```
|
|
|
|
You can include additional nginx configuration by setting the `matrix_nginx_proxy_proxy_http_additional_server_configuration_blocks` variable.
|
|
|
|
```yaml
|
|
matrix_nginx_proxy_proxy_http_additional_server_configuration_blocks:
|
|
- |
|
|
# These lines will be included in the nginx configuration.
|
|
# This is at the top level of the file, so you will need to define all of the `server { ... }` blocks.
|
|
- |
|
|
# For advanced use, have a look at the template files in `roles/matrix-nginx-proxy/templates/nginx/conf.d`
|
|
```
