jackal
An XMPP server written in Go.
About
jackal is a free, open-source, high performance XMPP server which aims to be known for its stability, simple configuration and low resource consumption.
Features
jackal supports the following features:
- Customizable
- 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)
Installing
Getting Started
To start using jackal, install Go 1.13+ 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 $GOPATH/bin path.
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 "CREATE USER IF NOT EXISTS 'jackal'@'localhost' IDENTIFIED BY 'password';" | mysql -h localhost -u root -p
echo "GRANT ALL ON jackal.* TO 'jackal'@'localhost';" | 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.
wget https://raw.githubusercontent.com/ortuman/jackal/master/sql/mysql.up.sql
Load database schema into the database.
mysql -h localhost -D jackal -u jackal -p < mysql.up.sql
Your database is now ready to connect with jackal.
Using PostgreSQL
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
That's it!
Push notifications
Support for XEP-0357: Push Notifications is not yet available in jackal.
However there's a chance to forward offline messages to some external service by configuring offline module as follows:
mod_offline:
queue_size: 2500
gateway:
type: http
auth: a-secret-token-here
pass: http://127.0.0.1:6666
Each time a message is sent to an offline user a POST http request to the pass URL is made, using the specified Authorization header and including the message stanza into the request body.
