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
md5 for the lines below:
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:
sudo systemctl start postgresql sudo systemctl enable postgresql
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; CREATE DATABASE postgres=# CREATE USER netbox WITH PASSWORD 'J5brHrAXFLQSif0K'; CREATE ROLE postgres=# GRANT ALL PRIVILEGES ON DATABASE netbox TO netbox; GRANT 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 "127.0.0.1") 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.
