PostgreSQL Database Installation

This section entails the installation and configuration of a local PostgreSQL database. If you already have a PostgreSQL database service in place, skip to the next section.


NetBox requires PostgreSQL 9.6 or higher. Please note that MySQL and other relational databases are not currently supported.


sudo apt update
sudo apt install -y postgresql libpq-dev
sudo yum install -y postgresql-server libpq-devel
sudo postgresql-setup --initdb


PostgreSQL 9.6 and later are available natively on CentOS 8.2. If using an earlier CentOS release, you may need to install it from an RPM.

CentOS configures ident host-based authentication for PostgreSQL by default. Because NetBox will need to authenticate using a username and password, modify /var/lib/pgsql/data/pg_hba.conf to support MD5 authentication by changing ident to md5 for the lines below:

host    all             all               md5
host    all             all             ::1/128                 md5

Once PostgreSQL has been installed, start the service and enable it to run at boot:

sudo systemctl start postgresql
sudo systemctl enable postgresql

Database Creation

At a minimum, we need to create a database for NetBox and assign it a username and password for authentication. This is done with the following commands.


Do not use the password from the example. Choose a strong, random password to ensure secure database authentication for your NetBox installation.

$ sudo -u postgres psql
psql (12.5 (Ubuntu 12.5-0ubuntu0.20.04.1))
Type "help" for help.

postgres=# CREATE DATABASE netbox;
postgres=# CREATE USER netbox WITH PASSWORD 'J5brHrAXFLQSif0K';
postgres=# GRANT ALL PRIVILEGES ON DATABASE netbox TO netbox;
postgres=# \q

Verify Service Status

You can verify that authentication works issuing the following command and providing the configured password. (Replace localhost with your database server if using a remote database.)

$ psql --username netbox --password --host localhost netbox
Password for user netbox: 
psql (12.5 (Ubuntu 12.5-0ubuntu0.20.04.1))
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
Type "help" for help.

netbox=> \conninfo
You are connected to database "netbox" as user "netbox" on host "localhost" (address "") at port "5432".
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
netbox=> \q

If successful, you will enter a netbox prompt. Type \conninfo to confirm your connection, or type \q to exit.
