An XMPP server written in Go.
jackal is a free, open-source, high performance XMPP server which aims to be known for its stability, simple configuration and low resource consumption.
jackal supports the following features:
- Enforced SSL/TLS
- Stream compression (zlib)
- Database connectivity for storing offline messages and user settings (BadgerDB, MySQL 5.7+, MariaDB 10.2+, PostgreSQL 9.5+)
- Cross-platform (OS X, Linux)
To start using jackal, install Go 1.11+ and run the following commands:
$ go get -d github.com/ortuman/jackal $ cd $GOPATH/src/github.com/ortuman/jackal $ make install
This will retrieve the code and install the
jackal server application into your
By default the application will try to read server configuration from
/etc/jackal/jackal.yml file, but alternatively you can specify a custom configuration path from command line.
$ jackal --config=$GOPATH/src/github.com/ortuman/jackal/example.jackal.yml
MySQL database creation
Grant right to a dedicated 'jackal' user (replace
password with your desired password).
echo "GRANT ALL ON jackal.* TO 'jackal'@'localhost' IDENTIFIED BY 'password';" | mysql -h localhost -u root -p
Create 'jackal' database (using previously created password).
echo "CREATE DATABASE jackal;" | mysql -h localhost -u jackal -p
Download lastest version of the MySQL schema from jackal Github repository.
Load database schema into the database.
mysql -h localhost -D jackal -u jackal -p < mysql.sql
Your database is now ready to connect with jackal.
Create a user and a database for that user:
CREATE ROLE jackal WITH LOGIN PASSWORD 'password'; CREATE DATABASE jackal; GRANT ALL PRIVILEGES ON DATABASE jackal TO jackal;
Run the postgres script file to create database schema. In jackal's root directory run:
psql --user jackal --password -f sql/postgres.up.psql
Configure jackal to use PostgreSQL by editing the configuration file:
storage: type: pgsql pgsql: host: 127.0.0.1:5432 user: jackal password: password database: jackal
The purpose of clustering is to be able to use several servers for fault-tolerance and scalability.
jackal in clustering mode make sure to add a
cluster section configuration in each of the cluster nodes.
Here is an example of how this section should look like:
cluster: name: node1 port: 5010 hosts: [node2:5010, node3:5010]
Do not forget to include all cluster nodes, excluding the local one, in the
hosts array field. Otherwise the expected behavior will be undefined.
