How To Install Openstack On Ubuntu 18.04 With Devstack
With that in mind, we are going to add a new user called “stack” and assign sudo privileges.
To create stack user execute
sudo adduser -s /bin/bash -d /opt/stack -m stack
Next, run the command below to assign sudo privileges to the user
echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack
Step 3: Install git and download DevStack
Once you have successfully created the user ‘stack’ and assigned sudo privileges, switch to the user using the command.
su - stack
In most Ubuntu 18.04 systems, git comes already installed. If by any chance git is missing, install it by running the following command.
sudo apt install git -y
Using git, clone devstack’s git repository as shown.
git clone https://git.openstack.org/openstack-dev/devstack
Step 4: Create devstack configuration file
In this step, navigate to the devstack directory.
Then create a
local.conf configuration file.
Paste the following content
[[local|localrc]]# Password for KeyStone, Database, RabbitMQ and ServiceADMIN_PASSWORD=StrongAdminSecretDATABASE_PASSWORD=$ADMIN_PASSWORDRABBIT_PASSWORD=$ADMIN_PASSWORDSERVICE_PASSWORD=$ADMIN_PASSWORD# Host IP - get your Server/VM IP address from ip addr commandHOST_IP=10.208.0.10
