Install and configure MySQL database

Hue requires a SQL database such as MySQL, PostgreSQL, or Oracle to store small amounts of data, including user account information, query history, and permissions. The instructions in this topic are for installing the MySQL database.

Install MySQL on a host within your cluster. For instructions, refer to the MySQL Installation Guide.

To configure Hue to store data in the MySQL database:

SSH into the host on which you have installed MySQL.
Create a new database in MySQL as follows:
```
mysql> create database hue;
```
Run the following command to grant privileges to a Hue user to manage the database:
```
mysql> grant all on hue.* to ‘hue’@‘localhost’ identified by ‘secretpassword’;
```
