Step 1: Download and install PostgreSQL
RHEL and CentOS 7 include PostgreSQL version 9.2. However, on these OS versions, Hue is compatible only with PostgreSQL versions 10, 11.x, and 12. Therefore, you must download and install the PostgreSQL distribution separately.
- Download the PostgreSQL distribution from https://www.postgresql.org/download/ based on your OS version.
Install the PostgreSQL server using the following command:
sudo yum install postgresql-server
