Dendrite can be run in one of two configurations:
|
||||
|
||||
* A cluster of individual components, dealing with different aspects of the
|
||||
Matrix protocol (see [WIRING.md](./WIRING.md)). Components communicate with
|
||||
one another via [Apache Kafka](https://kafka.apache.org).
|
||||
* **Polylith mode**: A cluster of individual components, dealing with different
|
||||
aspects of the Matrix protocol (see [WIRING.md](WIRING.md)). Components communicate with each other using internal HTTP APIs and [Apache Kafka](https://kafka.apache.org). This will almost certainly be the preferred model
|
||||
for large-scale deployments.
|
||||
|
||||
* A monolith server, in which all components run in the same process. In this
|
||||
configuration, Kafka can be replaced with an in-process implementation
|
||||
called [naffka](https://github.com/matrix-org/naffka).
|
||||
* **Monolith mode**: All components run in the same process. In this mode,
|
||||
Kafka is completely optional and can instead be replaced with an in-process
|
||||
lightweight implementation called [Naffka](https://github.com/matrix-org/naffka). This will usually be the preferred model for low-volume, low-user
|
||||
or experimental deployments.
|
||||
|
||||
Regardless of whether you are running in polylith or monolith mode, each Dendrite component that requires storage has its own database. Both Postgres
|
||||
and SQLite are supported and can be mixed-and-matched across components as
|
||||
needed in the configuration file.
|
||||
|
||||
Be advised that Dendrite is still developmental and it's not recommended for
|
||||
use in production environments yet!
|
||||
|
||||
## Requirements
|
||||
|
||||
- Go 1.13+
|
||||
- Postgres 9.5+
|
||||
- For Kafka (optional if using the monolith server):
|
||||
- Unix-based system (https://kafka.apache.org/documentation/#os)
|
||||
- JDK 1.8+ / OpenJDK 1.8+
|
||||
- Apache Kafka 0.10.2+ (see [scripts/install-local-kafka.sh](scripts/install-local-kafka.sh) for up-to-date version numbers)
|
||||
Dendrite requires:
|
||||
|
||||
* Go 1.13 or higher
|
||||
* Postgres 9.5 or higher (if using Postgres databases, not needed for SQLite)
|
||||
|
||||
## Setting up a development environment
|
||||
If you want to run a polylith deployment, you also need:
|
||||
|
||||
Assumes Go 1.13+ and JDK 1.8+ are already installed and are on PATH.
|
||||
* Apache Kafka 0.10.2+

## Configuration
|
||||
|
||||
### SQLite database setup
|
||||
|
||||
Dendrite can use the built-in SQLite database engine for small setups.
|
||||
The SQLite databases do not need to be preconfigured - Dendrite will
|
||||
create them automatically at startup.
|
||||
|
||||
### Postgres database setup
|
||||
|
||||
Dendrite requires a postgres database engine, version 9.5 or later.
|
||||
Assuming that Postgres 9.5 (or later) is installed:
|
||||
|
||||
* Create role, choosing a new password when prompted:
|
||||
|
||||
* Create role:
|
||||
```bash
|
||||
sudo -u postgres createuser -P dendrite # prompts for password
|
||||
sudo -u postgres createuser -P dendrite
|
||||
```
|
||||
* Create databases:
|
||||
|
||||
* Create the component databases:
|
||||
|
||||
```bash
|
||||
for i in account device mediaapi syncapi roomserver serverkey federationsender publicroomsapi appservice naffka; do
|
||||
sudo -u postgres createdb -O dendrite dendrite_$i

||||
@ -78,42 +115,56 @@ Dendrite requires a postgres database engine, version 9.5 or later.
|
||||
|
||||
(On macOS, omit `sudo -u postgres` from the above commands.)
|
||||
|
||||
### Crypto key generation
|
||||
### Server key generation
|
||||
|
||||
Generate the keys:
|
||||
Each Dendrite server requires unique server keys.
|
||||
|
||||
Generate the self-signed SSL certificate for federation:
|
||||
|
||||
```bash
|
||||
# Generate a self-signed SSL cert for federation:
|
||||
test -f server.key || openssl req -x509 -newkey rsa:4096 -keyout server.key -out server.crt -days 3650 -nodes -subj /CN=localhost
|
||||
```
|
||||
|
||||
# generate ed25519 signing key
|
||||
Generate the server signing key:
|
||||
|
||||
```
|
||||
test -f matrix_key.pem || ./bin/generate-keys -private-key matrix_key.pem
|
||||
```
|
||||
|
||||
### Configuration
|
||||
### Configuration file
|
||||
|
||||
Create config file, based on `dendrite-config.yaml`. Call it `dendrite.yaml`. Things that will need editing include *at least*:
|
||||
* `server_name`
|
||||
* `database/*` (All lines in the database section must have the username and password of the user created with the `createuser` command above. eg:`dendrite:password@localhost`)
|
||||
|
||||
* The `server_name` entry to reflect the hostname of your Dendrite server
|
||||
* The `database` lines with an updated connection string based on your
|
||||
desired setup, e.g. replacing `component` with the name of the component:
|
||||
* For Postgres: `postgres://dendrite:password@localhost/component`
|
||||
* For SQLite on disk: `file:component.db` or `file:///path/to/component.db`
|
||||
* Postgres and SQLite can be mixed and matched.
|
||||
* The `use_naffka` option if using Naffka in a monolith deployment
|
||||
|
||||
There are other options which may be useful so review them all. In particular,
|
||||
if you are trying to federate from your Dendrite instance into public rooms
|
||||
then configuring `key_perspectives` (like `matrix.org` in the sample) can
|
||||
help to improve reliability considerably by allowing your homeserver to fetch
|
||||
public keys for dead homeservers from somewhere else.
|
||||
|
||||
## Starting a monolith server
|
||||
|
||||
It is possible to use 'naffka' as an in-process replacement to Kafka when using
|
||||
the monolith server. To do this, set `use_naffka: true` in `dendrite.yaml` and uncomment
|
||||
the necessary line related to naffka in the `database` section. Be sure to update the
|
||||
database username and password if needed.

|

|
||||
|
||||
The monolith server can be started as shown below. By default it listens for
|
||||
HTTP connections on port 8008, so point your client at
|
||||
`http://localhost:8008`. If you set `--tls-cert` and `--tls-key` as shown
|
||||
below, it will also listen for HTTPS connections on port 8448.
