Installing MAAS as snap package

Step 1 – Update packages by apt command:

$ sudo apt update

Step 2 – Let’s install MAAS:

$ sudo snap install maas


Initializing MAAS

For production, we need to Initialize MAAS. Firstly, we must check for updates:

$ sudo apt update -y


Then we will install PostgreSQL:

$ sudo apt install -y postgresql


Secondly, we will create a database for MAAS. Here the database is called maas, user named maasuser, the password is maas123:

$ sudo -u postgres psql

create user maasuser with encrypted password ‘maas123’;

create database maas;

grant all privileges on database maas to maasuser;


Thirdly, we need to edit the file /etc/postgresql/10/main/pg_hba.conf:

$ sudo nano /etc/postgresql/10/main/pg_hba.conf

Then add the following line:

host maas maaszeljko 0/0 md5

Save it and exit.

Now we will start initializing MAAS:

$ sudo maas init region+rack --database-uri "postgres://maasuser:[email protected]/maas"

Replace maasuser with your username just created, maas123 by your password.

To create the admin account for the web interface, run:

$ sudo maas createadmin

To check MAAS service status, run:

$ sudo maas status


Testing connection
