Chapter 3. Installing the all-in-one Red Hat OpenStack Platform environment

Create a non-root user on the all-in-one host:

[root@all-in-one]# useradd stack

Set the password for the stack user:

[root@all-in-one]# passwd stack

Disable password requirements when using sudo as the stack user:

[root@all-in-one]# echo "stack ALL=(root) NOPASSWD:ALL" | tee -a /etc/sudoers.d/stack
[root@all-in-one]# chmod 0440 /etc/sudoers.d/stack

Log in as the non-root user on the all-in-one host:

$ ssh stack@<all-in-one>

Register the machine with Red Hat Subscription Manager. Enter your Red Hat subscription credentials at the prompt:

[stack@all-in-one]$ sudo subscription-manager register

Attach your Red Hat subscription to the entitlement server:

[stack@all-in-one]$ sudo subscription-manager attach --auto

Lock the undercloud to Red Hat Enterprise Linux 9.0:

$ sudo subscription-manager release --set=9.0

Run the following commands to install dnf-utils, disable all default repositories, and then enable the necessary repositories:

[stack@all-in-one]$ sudo dnf install -y dnf-utils
[stack@all-in-one]$ sudo subscription-manager repos --disable=*
[stack@all-in-one]$ sudo subscription-manager repos \
--enable=rhel-9-for-x86_64-baseos-eus-rpms \
--enable=rhel-9-for-x86_64-appstream-eus-rpms \
--enable=rhel-9-for-x86_64-highavailability-eus-rpms \
--enable=openstack-17-for-rhel-9-x86_64-rpms \
--enable=fast-datapath-for-rhel-9-x86_64-rpms

Update the base operating system and reboot the system:

[stack@all-in-one]$ sudo dnf update
[stack@all-in-one]$ sudo reboot

Install the TripleO command line interface (CLI):

[stack@all-in-one]$ sudo dnf install -y python3-tripleoclient
