Next, reboot the system with the command:

Step 2: Create a Stack user and assign sudo privileges

Best practice requires that devstack be run with a regular user account with sudo privileges.

Therefore, the article will add a new user called “stack” and specify sudo privileges.

To create a stack user, execute the command:

sudo adduser -s /bin/bash -d /opt/stack -m stack

Next, run the command below to assign sudo privileges to the stack user:

echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack

Sample output:

Step 3: Install git and download DevStack

Once you have successfully created the stack user and specified sudo privileges, switch to this user using the command.

su - stack

In most Ubuntu 18.04 systems, git comes pre-installed. If by chance git is missing, install it by running the following command:

sudo apt install git -y

Sample output:

Cài đặt git
Install git

Using git, clone (clone) Devstack’s git repository as shown.

git clone https://git.openstack.org/openstack-dev/devstack

Step 4: Create Devstack configuration file

cd devstack

Then create the configuration file local.conf:
