Create a new user in MySQL, and grant privileges to it to manage the database using the MySQL database admin utility:

# mysql -u root -p
CREATE USER $HUEUSER IDENTIFIED BY '$HUEPASSWORD';
GRANT ALL PRIVILEGES on *.* to ‘$HUEUSER’@’localhost’ WITH GRANT OPTION;
GRANT ALL on $HUEUSER.* to ‘$HUEUSER’@’localhost’ IDENTIFIED BY
$HUEPASSWORD;
FLUSH PRIVILEGES;

Create the MySQL database for Hue:

# mysql -u root -p
CREATE DATABASE $DBNAME;

Open the /etc/hue/conf/hue.ini file and edit the [[database]] section:

[[database]]
engine=mysql
host=$DATABASEIPADDRESSORHOSTNAME
port=$PORT
user=$HUEUSER
password=$HUEPASSWORD
name=$DBNAME

Synchronize Hue with the external database to create the schema and load the data.

cd /usr/lib/hue
source build/env/bin/activate
hue syncdb --noinput
hue migrate
deactivate
