Let’s get started with the install of PostgreSQL 12 on Fedora.
Step 1: Update Fedora System
Ensure system packages are up to date:
sudo dnf install -y vim bash-completion wget
sudo dnf update -ySince you may have Kernel updates, it is recommended to reboot your system after an upgrade:
sudo rebootStep 2: Add PostgreSQL Yum Repository
Add PostgreSQL Yum Repository to your Fedora system by running the below command:
Fedora 38:
sudo dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/F-38-x86_64/pgdg-fedora-repo-latest.noarch.rpmFedora 37:
sudo dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/F-37-x86_64/pgdg-fedora-repo-latest.noarch.rpm
Fedora 36:
sudo dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/F-36-x86_64/pgdg-fedora-repo-latest.noarch.rpmFedora 35:
sudo dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/F-35-x86_64/pgdg-fedora-repo-latest.noarch.rpmFedora 34:
sudo dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/F-34-x86_64/pgdg-fedora-repo-latest.noarch.rpmFedora 33:
sudo dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/F-33-x86_64/pgdg-fedora-repo-latest.noarch.rpmFedora 32:
sudo dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/F-32-x86_64/pgdg-fedora-repo-latest.noarch.rpm
Step 3: Install PostgreSQL 12 on Fedora

If you have a running Firewall service and remote clients should connect to your database server, allow PostgreSQL service.
sudo firewall-cmd --add-service=postgresql --permanent
sudo firewall-cmd --reloadStep 5: Enable remote access to PostgreSQL (Optional)
If you have Applications connecting to the database server over the network, edit the file /var/lib/pgsql/12/data/postgresql.conf and set Listen address to your server IP address or “*” for all interfaces.
$ sudo vim /var/lib/pgsql/12/data/postgresql.conf
listen_addresses = '*'Also set PostgreSQL to accept remote connections from allowed hosts.
$ sudo vim /var/lib/pgsql/12/data/pg_hba.conf
# Accept from anywhere
host all all 0.0.0.0/0 md5
# Accept from trusted subnet
host all all 10.10.10.0/24 md5
Restart PostgreSQL 12 service after making the change.
sudo systemctl restart postgresql-12Step 6: Set PostgreSQL admin user’s password
Set PostgreSQL admin user password.
sudo su - postgres
psql -c "alter user postgres with password 'StrongPassword'"Where StrongPassword is the new password for postgres user.
Step 7: Install pgAdmin 4 Web Management
If you need an easy way for managing PostgreSQL database server (Similar to phpMyAdmin for MySQL), consider installing pgAdmin4.
