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.
!!! warning "PostgreSQL 11 or later required" NetBox requires PostgreSQL 11 or later. Please note that MySQL and other relational databases are not supported.
Installation
=== "Ubuntu"
```no-highlight
sudo apt update
sudo apt install -y postgresql
```
=== "CentOS"
```no-highlight
sudo yum install -y postgresql-server
sudo postgresql-setup --initdb
```
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:
```no-highlight
host all all 127.0.0.1/32 md5
host all all ::1/128 md5
```
Once PostgreSQL has been installed, start the service and enable it to run at boot:
```no-highlight
sudo systemctl start postgresql
sudo systemctl enable postgresql
```
Before continuing, verify that you have installed PostgreSQL 11 or later:
psql -V
Database Creation
At a minimum, we need to create a database for NetBox and assign it a username and password for authentication. Start by invoking the PostgreSQL shell as the system Postgres user.
sudo -u postgres psql
Within the shell, enter the following commands to create the database and user (role), substituting your own value for the password:
CREATE DATABASE netbox;
CREATE USER netbox WITH PASSWORD 'J5brHrAXFLQSif0K';
ALTER DATABASE netbox OWNER TO netbox;
!!! danger "Use a strong password" Do not use the password from the example. Choose a strong, random password to ensure secure database authentication for your NetBox installation.
Once complete, enter \q to exit the PostgreSQL shell.
Verify Service Status
You can verify that authentication works by executing the psql command and passing the configured username and password. (Replace localhost with your database server if using a remote database.)
$ psql --username netbox --password --host localhost netbox
Password for user netbox:

Type "help" for help.
netbox=> \conninfo
You are connected to database "netbox" as user "netbox" on host "localhost" (address "127.0.0.1") at port "5432".

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