Installing

Getting Started

To start using jackal, install Go 1.10+ and run go get:

$ go get github.com/ortuman/jackal

This will retrieve the code and install the jackal server application into your $GOBIN 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 "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.

wget https://raw.githubusercontent.com/ortuman/jackal/master/sql/mysql.sql

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.
