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;

where $HUEUSER is the Hue user name and $HUEPASSWORD is the Hue user password.

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 (modify for your MySQL setup).

[[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:

/usr/lib/hue/build/env/bin/hue syncdb --noinput

Start Hue:

/etc/init.d/hue start
