After completing the first part of the Openstack Lab guide series:

Openstack Liberty Lab Part 1: Setting up the network and all prerequisites

We are ready to install the Openstack package in the second part of the guide. Starting from the third part, we will configure it. All the packages we will install include:

1. Openstack OpenStack identity (critical) service
2. OpenStack Image Service (Overview) Service
3. OpenStack Computing Service (Nova)
4. OpenStack dashboard (Horizo​​n) service
5. OpenStack network (Neutron) service
6. OpenStack block storage (Cinder) service
7. OpenStack Object Storage (Fast) Service
8. OpenStack Orchestration Service (Hot) Service
9. OpenStack metering service (ceilometer) service

We will configure it in the order of installation later. Start from Keystone to complete the configuration of Ceilometer metering service. Without much theory, let’s start installing the above services. Note: You must enable both epel and rdo-release repositories. To view the list of enabled repositories in CentOS /RHEL, do the following:

                      
                        [[email protected] ~]# yum repolist 
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirror.bitco.co.za
 * epel: ftp-stud.hs-esslingen.de
 * extras: mirror.bitco.co.za
 * updates: mirror.bitco.co.za
repo id                   repo name                                       status
base/7/x86_64             CentOS-7 - Base                                 9,007
epel/x86_64               Extra Packages for Enterprise Linux 7 - x86_64  9,692
extras/7/x86_64           CentOS-7 - Extras                                 228
openstack-liberty/x86_64  OpenStack Liberty Repository                      976
updates/7/x86_64          CentOS-7 - Updates                                991
repolist: 20,894
[[email protected] ~]# 
                      
                    

In addition, you can enable cat and grep from the repo content:

                      
                        [[email protected] ~]# cat /etc/yum.repos.d/epel.repo | grep enabled
enabled=1
enabled=0
enabled=0
[[email protected] ~]# cat /etc/yum.repos.d/rdo-release.repo | grep enabled
enabled=1
[[email protected] ~]#
                      
                    

From the epel repository output, we only need to enable the first repository, which contains stable Extra Packages for Enterprise Linux 7. Since the repositories we need are enabled, we can proceed to install the Openstack service package. Remember, this is an Openstack Libery ALL IN ONE installation, and we run all openstack services on a single node server.

We have installed all Openstack services and these services will be configured in the subsequent parts of this series. If you want to install other Openstack service packages, such as load balancers, firewalls, Trove, etc., you can also install them here.
