Tested solution on centos 7 minimal last edition

• sudo yum upgrade (after installation)
• Adduser confluence
• Passwd confluence “your password”

Make the user confluence root with visudo

## Allow root to run any commands anywhere

from now on, everything is done under the user confluence unless noted otherwise

Files for postgres are in  /var/lib/pgsql/9.6 and data in  /var/lib/pgsql/9.6/data

Install all the postgresql files available:

• sudo yum install postgresql96*

Issue the following commands to set a password for the postgres database user.

• su - postgres

Create database user and database

I didn't quite get this part:

Add the JAVA_HOME the path to java

• sudo vi /etc/profile
• export JAVA_HOME=/usr/java/jdk1.8.0_172-amd64
• export JAVA_PATH=$JAVA_HOME

Where in the /profile should I add those two things you listed below: 

• sudo vi /etc/profile
