Chapter 3. Installing the all-in-one Red Hat OpenStack Platform environment
Before you can begin configuring, deploying, and testing your all-in-one environment, you must configure a non-root user and install the necessary packages and dependencies:
Create a non-root user on the all-in-one host:
[root@all-in-one]# useradd stack
Set the password for the
stackuser:[root@all-in-one]# passwd stack
Disable password requirements when using
sudoas thestackuser:[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
NoteThe
--autooption might not subscribe you to the correct subscription pool. Ensure that you subscribe to the correct pool, otherwise you might not be able to enable all of the repositories necessary for this installation. Use thesubscription-manager list --all --availablecommand to identify the correct pool ID.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-8-for-x86_64-baseos-rpms \ --enable=rhel-8-for-x86_64-appstream-rpms \ --enable=rhel-8-for-x86_64-highavailability-rpms \ --enable=ansible-2.8-for-rhel-8-x86_64-rpms \ --enable=openstack-15-for-rhel-8-x86_64-rpms \ --enable=fast-datapath-for-rhel-8-x86_64-rpms
NoteThe all-in-one environment is a Technology Preview feature in Red Hat OpenStack Platform 15.
Install the TripleO command line interface (CLI):
[stack@all-in-one]$ sudo dnf install -y python3-tripleoclient
