# Installing Dendrite
|
|
|
|
Dendrite can be run in one of two configurations:
|
|
|
|
* **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.
|
|
|
|
* **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
|
|
|
|
Dendrite requires:
|
|
|
|
* Go 1.13 or higher
|
|
* Postgres 9.5 or higher (if using Postgres databases, not needed for SQLite)
|
|
|
|
If you want to run a polylith deployment, you also need:
|
|
|
|
* Apache Kafka 0.10.2+
|
|
|
|
## Building up a monolith deploment
|
|
|
|
Start by cloning the code:
|
|
|
|
```bash
|
|
git clone https://github.com/matrix-org/dendrite
|
|
cd dendrite
|
|
```
|
|
|
|
Then build it:
|
|
|
|
```bash
|
|
go build -o bin/dendrite-monolith-server ./cmd/dendrite-monolith-server
|
|
go build -o bin/generate-keys ./cmd/generate-keys
|
|
```
|
|
|
|
## Building up a polylith deployment
|
|
|
|
Start by cloning the code:
|
|
|
|
```bash
|
|
git clone https://github.com/matrix-org/dendrite
|
|
cd dendrite
|
|
```
|
|
|
|
Then build it:
|
|
|
|
```bash
|
|
./build.sh
|
|
```
|
|
|
|
Install and start Kafka (c.f. [scripts/install-local-kafka.sh](scripts/install-local-kafka.sh)):
|
|
|
|
```bash
|
|
KAFKA_URL=http://archive.apache.org/dist/kafka/2.1.0/kafka_2.11-2.1.0.tgz
|
|
|
|
# Only download the kafka if it isn't already downloaded.
|
|
test -f kafka.tgz || wget $KAFKA_URL -O kafka.tgz
|
|
# Unpack the kafka over the top of any existing installation
|
|
mkdir -p kafka && tar xzf kafka.tgz -C kafka --strip-components 1
|
|
|
|
# Start the zookeeper running in the background.
|
|
# By default the zookeeper listens on localhost:2181
|
|
kafka/bin/zookeeper-server-start.sh -daemon kafka/config/zookeeper.properties
|
|
|
|
# Start the kafka server running in the background.
|
|
# By default the kafka listens on localhost:9092
|
|
kafka/bin/kafka-server-start.sh -daemon kafka/config/server.properties
|
|
```
|
|
|
|
On macOS, you can use [Homebrew](https://brew.sh/) for easier setup of Kafka:
|
|
|
|
```bash
|
|
brew install kafka
|
|
brew services start zookeeper
|
|
brew services start kafka
|
|
```
|
|
|
|
## Configuration
|
|
|
|
### SQLite database setup
|
|
|
|
Dendrite can use the built-in SQLite database engine for small setups.
|
|
The SQLite databases do not need to be preconfigured - Dendrite will
|
|
create them automatically at startup.
|
|
|
|
### Postgres database setup
|
|
|
|
Assuming that Postgres 9.5 (or later) is installed:
|
|
|
|
* Create role, choosing a new password when prompted:
|
|
|
|
```bash
|
|
sudo -u postgres createuser -P dendrite
|
|
```
|
|
|
|
* Create the component databases:
|
|
|
|
```bash
|
|
for i in account device mediaapi syncapi roomserver serverkey federationsender publicroomsapi appservice naffka; do
|
|
sudo -u postgres createdb -O dendrite dendrite_$i
|
|
done
|
|
```
|
|
|
|
(On macOS, omit `sudo -u postgres` from the above commands.)
|
|
|
|
### Server key generation
|
|
|
|
Each Dendrite server requires unique server keys.
|
|
|
|
Generate the self-signed SSL certificate for federation:
|
|
|
|
```bash
|
|
test -f server.key || openssl req -x509 -newkey rsa:4096 -keyout server.key -out server.crt -days 3650 -nodes -subj /CN=localhost
|
|
```
|
|
|
|
Generate the server signing key:
|
|
|
|
```
|
|
test -f matrix_key.pem || ./bin/generate-keys -private-key matrix_key.pem
|
|
```
|
|
|
|
### Configuration file
|
|
|
|
Create config file, based on `dendrite-config.yaml`. Call it `dendrite.yaml`. Things that will need editing include *at least*:
|
|
|
|
* 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 your `dendrite.yaml` configuration and uncomment the relevant Naffka line 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 you can configure your Matrix client to use
|
|
`http://localhost:8008` as the server. If you set `--tls-cert` and `--tls-key`
|
|
as shown below, it will also listen for HTTPS connections on port 8448.
|
|
|
|
```bash
|
|
./bin/dendrite-monolith-server --tls-cert=server.crt --tls-key=server.key
|
|
```
|
|
|
|
## Starting a polylith deployment
|
|
|
|
The following contains scripts which will run all the required processes in order to point a Matrix client at Dendrite. Conceptually, you are wiring together to form the following diagram:

A ==> B = Kafka (A = producer, B = consumer)
|
|
```
|
|
|
|
### Client proxy
|
|
|
|
This is what Matrix clients will talk to. If you use the script below, point
|
|
your client at `http://localhost:8008`.
|
|
|
|
```bash
|
|
./bin/client-api-proxy \
|
|
--bind-address ":8008" \
|
|
--client-api-server-url "http://localhost:7771" \
|
|
--sync-api-server-url "http://localhost:7773" \
|
|
--media-api-server-url "http://localhost:7774" \
|
|
--public-rooms-api-server-url "http://localhost:7775" \
|
|
```
|
|
|
|
### Federation proxy
|
|
|
|
This is what Matrix servers will talk to. This is only required if you want
|
|
to support federation.
|
|
|
|
```bash
|
|
./bin/federation-api-proxy \
|
|
--bind-address ":8448" \
|
|
--federation-api-url "http://localhost:7772" \
|
|
--media-api-server-url "http://localhost:7774" \
|
|
```
|
|
|
|
### Client API server
|
|
|
|
This is what implements message sending. Clients talk to this via the proxy in
|
|
order to send messages.
|
|
|
|
```bash
|
|
./bin/dendrite-client-api-server --config=dendrite.yaml
|
|
```
|
|
|
|
### Room server
|
|
|
|
This is what implements the room DAG. Clients do not talk to this.
|
|
|
|
```bash
|
|
./bin/dendrite-room-server --config=dendrite.yaml
|
|
```
|
|
|
|
### Sync server
|
|
|
|
This is what implements `/sync` requests. Clients talk to this via the proxy
|
|
in order to receive messages.
|
|
|
|
```bash
|
|
./bin/dendrite-sync-api-server --config dendrite.yaml
|
|
```
|
|
|
|
### Media server
|
|
|
|
This implements `/media` requests. Clients talk to this via the proxy in
|
|
order to upload and retrieve media.
|
|
|
|
```bash
|
|
./bin/dendrite-media-api-server --config dendrite.yaml
|
|
```
|
|
|
|
### Public room server
|
|
|
|
This implements `/directory` requests. Clients talk to this via the proxy
|
|
in order to retrieve room directory listings.
|
|
|
|
```bash
|
|
./bin/dendrite-public-rooms-api-server --config dendrite.yaml
|
|
```
|
|
|
|
### Federation API server
|
|
|
|
This implements federation requests. Servers talk to this via the proxy in
|
|
order to send transactions. This is only required if you want to support
|
|
federation.
|
|
|
|
```bash
|
|
./bin/dendrite-federation-api-server --config dendrite.yaml
|
|
```
|
|
|
|
### Federation sender
|
|
|
|
This sends events from our users to other servers. This is only required if
|
|
you want to support federation.
|
|
|
|
```bash
|
|
./bin/dendrite-federation-sender-server --config dendrite.yaml
|
|
```
|
|
|
|
### Appservice server
|
|
|
|
This sends events from the network to [application
|
|
services](https://matrix.org/docs/spec/application_service/unstable.html)
|
|
running locally. This is only required if you want to support running
|
|
application services on your homeserver.
|
|
|
|
```bash
|
|
./bin/dendrite-appservice-server --config dendrite.yaml
|
|
```
|
|
|
|
### Key server
|
|
|
|
This manages end-to-end encryption keys (or rather, it will do when it's
|
|
finished).
|
|
|
|
```bash
|
|
./bin/dendrite-key-server --config dendrite.yaml
|
|
```
|
