How To Install PostgreSQL on Fedora 35

Install PostgreSQL on Fedora 35

In this tutorial, we will show you how to install PostgreSQL on Fedora 35. For those of you who didn’t know, PostgreSQL is a powerful, open-source object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance. Postgres is a free and open-source relational database management system emphasizing extensibility and SQL compliance.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of the PostgreSQL 14 on a Fedora 35.

Install PostgreSQL on Fedora 35

Step 1. Before proceeding, update your Fedora operating system to make sure all existing packages are up to date. Use this command to update the server packages:

sudo dnf upgrade
sudo dnf update

Step 2. Installing PostgreSQL on Fedora 35.

By default, PostgreSQL is available on Fedora 35 base repository. Then we can install PostgreSQL with the following command below:

sudo dnf module enable postgresql:14
sudo dnf install -y postgresql-server postgresql-contrib

Once the installation is complete, initialize the PostgreSQL database with the following command:

sudo postgresql-setup initdb

Next, start PostgreSQL and optionally enable it to start after reboot:

sudo systemctl start postgresql
sudo systemctl enable postgresql

Verify PostgreSQL the installation:

sudo -u postgres psql -c "SELECT version();"

Step 3. Configure Firewall.

For remote clients connectivity, you may have to permit access in the firewall:

sudo firewall-cmd --add-service=postgresql --permanent
sudo firewall-cmd --reload

Step 4. Accessing the PostgreSQL command prompt.

Once installing the PostgreSQL database server, by default, it creates a user ‘postgres’ with role ‘postgres’. It also creates a system account with the same name ‘postgres’. So to connect to the Postgres server, log in to your system as a user of Postgres and connect database:

sudo -i -u postgres

You can access a PostgreSQL prompt using the psql utility:

psql

Now you are logged in to the PostgreSQL database server. To check login info use the following command from the database command prompt:

postgres-# conninfo

To disconnect from the PostgreSQL database command prompt just type the below command and press enter. It will return you back to the Ubuntu command prompt:

postgres-# q

Next, create a database by using the following command:

### For example, let us create a new user called “godet” with password “freakz”, and database called “rantydb”. ###
sudo -u postgres createuser -D -A -P godet
sudo -u postgres createdb -O godet freakz

Congratulations! You have successfully installed PostgreSQL. Thanks for using this tutorial for installing PostgreSQL 14 on your Fedora 35 system. For additional help or useful information, we recommend you check the official PostgreSQL website.
