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). Components communicate with one another via Apache Kafka.
-
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.
- Go 1.11+
- 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 for up-to-date version numbers)
Assumes Go 1.10+ and JDK 1.8+ are already installed and are on PATH.
# Get the code
git clone https://github.com/matrix-org/dendrite
cd dendrite
# Build it
./build.shIf using Kafka, install and start it (c.f. scripts/install-local-kafka.sh):
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 $KAFKA_URL -O kafka.tgz
# Unpack the kafka over the top of any existing installation
mkdir -p kafka && tar xzf kafka.tgz -C kafka --strip-components 1
# Start the zookeeper running in the background.
# By default the zookeeper listens on localhost:2181
kafka/bin/zookeeper-server-start.sh -daemon kafka/config/zookeeper.properties
# Start the kafka server running in the background.
# By default the kafka listens on localhost:9092
kafka/bin/kafka-server-start.sh -daemon kafka/config/server.propertiesOn MacOS, you can use homebrew for easier setup of kafka
brew install kafka
brew services start zookeeper
brew services start kafkaDendrite requires a postgres database engine, version 9.5 or later.
- Create role:
sudo -u postgres createuser -P dendrite # prompts for password - Create databases:
for i in account device mediaapi syncapi roomserver serverkey federationsender publicroomsapi appservice naffka; do sudo -u postgres createdb -O dendrite dendrite_$i done
(On macOS, omit sudo -u postgres from the above commands.)
Generate the keys:
# 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
test -f matrix_key.pem || ./bin/generate-keys -private-key matrix_key.pemCreate config file, based on dendrite-config.yaml. Call it dendrite.yaml. Things that will need editing include at least:
server_namedatabase/*(All lines in the database section must have the username and password of the user created with thecreateusercommand above. eg:dendrite:password@localhost)
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.
./bin/dendrite-monolith-server --tls-cert=server.crt --tls-key=server.keyThe 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 = HTTP requests (A = client, B = server)
A ==> B = Kafka (A = producer, B = consumer)
This is what Matrix clients will talk to. If you use the script below, point your client at http://localhost:8008.
./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" \This is what implements message sending. Clients talk to this via the proxy in order to send messages.
./bin/dendrite-client-api-server --config=dendrite.yaml(If this fails with pq: syntax error at or near "ON", check you are using at least postgres 9.5.)
This is what implements the room DAG. Clients do not talk to this.
./bin/dendrite-room-server --config=dendrite.yamlThis is what implements /sync requests. Clients talk to this via the proxy in order to receive messages.
./bin/dendrite-sync-api-server --config dendrite.yamlThis implements /media requests. Clients talk to this via the proxy in order to upload and retrieve media.
./bin/dendrite-media-api-server --config dendrite.yamlThis implements /directory requests. Clients talk to this via the proxy in order to retrieve room directory listings.
./bin/dendrite-public-rooms-api-server --config dendrite.yamlThis is what Matrix servers will talk to. This is only required if you want to support federation.
./bin/federation-api-proxy \
--bind-address ":8448" \
--federation-api-url "http://localhost:7772" \
--media-api-server-url "http://localhost:7774" \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.
./bin/dendrite-federation-api-server --config dendrite.yamlThis sends events from our users to other servers. This is only required if you want to support federation.
./bin/dendrite-federation-sender-server --config dendrite.yamlThis sends events from the network to application services running locally. This is only required if you want to support running application services on your homeserver.
./bin/dendrite-appservice-server --config dendrite.yaml
