Create database from command line

📝 Title: Creating a Database from Command Line: The Easy Way!

Introduction: Are you trying to create a database from the command line but encountering a pesky password prompt? You're not alone! In this guide, we'll explore a simple solution to this common issue. Let's dive in and get your database up and running in no time! 💪

Common Issue: Password Prompt

The user who is trying to create the database is prompted for the password. This is a security measure to ensure that only authorized users can create databases.

Easy Solution:

1. Open your command line interface. Since you mentioned you are using CentOS, we'll assume you're using a terminal application or SSH.

2. Type the following command to create a database as the postgres user:

sudo -u postgres createdb test

1. Instead of using psql, we're using createdb directly. This command allows the postgres user to create the database without being prompted for a password.

Explanation:

By using the -u postgres flag, we are specifying that we want to execute the command as the postgres user. This user has the necessary permissions to create databases.

On the other hand, when using the psql command, the system prompts for the password because it tries to establish a connection to the postgres database.

Call-to-Action: Exploring Database Management

Congratulations! You've successfully created a database from the command line without the password prompt! 💪🎉
