In my earlier articles I shared the steps to bring up an openstack environment using tripleo deployment with an undercloud and overcloud. You should use tripleo deployment if you wish to bring up a multi node openstack environment. Although even with packstack you can bring up a multi node openstack deployment with two or more compute node but you cannot have more than one controller node when installing openstack using packstack. In this article I will share step by step tutorial to install OpenStack on CentOS 7 and RHEL 7 using Packstack.
In this article I have used KVM to create my Virtual Machines, I have written another article to install OpenStack on CentOS 7 (multinode) using Oracle VirtualBox installed on a Windows Laptop.
What is OpenStack?
OpenStack project, which is also called a cloud operational system, consists of a number of different projects developing separate subsystems. Any OpenStack installation can include only a part of them. Some subsystems can even be used separately or as part of any other OpenSource project. Their number is increasing from version to version of OpenStack project, both through the appearance of new ones and the functionality split of the existing ones. For example, nova-volume service was extracted as a separate Cinder project.
Make sure the hypervisor is enabled and supported on your blade
# grep -E ' svm | vmx' /proc/cpuinfo
You should see svm or vmx among the flags supported by the processor. Also if you execute the command:
# lsmod | grep kvm kvm_intel 143187 3 kvm 455843 1 kvm_intel
or
# lsmod | grep kvm kvm_amd 60314 3 kvm 461126 1 kvm_amd
you should see two kernel modules loaded in the memory. The kvm is the module independent of the vendor, and the kvm_intel
or kvm_amd
executes VT-x
or AMD-V
functionality, respectively

Install Openstack On CentOS 7 using Packstack
Packstack provides an easy way to deploy an OpenStack Platform environemnt on one or several machines because it is customizable through a answer file, which contains a set of parameters that allows custom configuration of underlying Openstack platform service.
What is Answer File?
Packstack provides by default an answer file template that deploys an all in one environment. When you run the packstack command non-interactively you must provide your configuration options via a text file, referred to as an answer file, instead of via standard input.
Step 1: Bring UP the physical host server
Firstly you need a base server on which you will create your entire Openstack cloud for which I have bought my server with RHEL 7.4
My setup detail
- Next login to your server and register it with Red Hat Subscription
- Install Virtual Machine Manager (if not already installed) using the "Application Installer"
- Next start creating your virtual machines as described in below chapters
Step 2: Configure BIND DNS Server
A DNS server is recommended before you install OpenStack on CentOS 7 using Packstack.
Below are my sample configuration files
# cd /var/named/chroot/var/named
Forward zone configuration file for the controller and compute nodes
# cat example.zone $TTL 1D @    IN SOA example. root (                     0    ; serial                     1D   ; refresh                     1H   ; retry                     1W   ; expire                     3H )  ; minimum @        IN NS  example.         IN A  127.0.0.1         IN A  10.43.138.12 openstack    IN A  10.43.138.12 controller   IN A  192.168.122.49 compute     IN A  192.168.122.215 compute-rhel  IN A  192.168.122.13 controller-rhel IN A  192.168.122.12
First reverse zone file for my physical host server hosting OpenStack
# cat example.rzone $TTL 1D @    IN SOA example. root.example. (                     0    ; serial                     1D   ; refresh                     1H   ; retry                     1W   ; expire                     3H )  ; minimum @    IN NS  example.     IN A  127.0.0.1     IN PTR localhost. 12   IN PTR openstack.example.
Second reverse zone file for controller and compute node
# cat openstack.rzone $TTL 1D @    IN SOA example. root.example. (                     0    ; serial                     1D   ; refresh                     1H   ; retry                     1W   ; expire                     3H )  ; minimum @    IN NS  example.     IN A  127.0.0.1     IN PTR localhost. 49   IN PTR controller.example. 215   IN PTR compute.example. 12   IN PTR controller-rhel.example. 13   IN PTR compute-rhel.example.
Step 3: Bring UP Compute VM
One of the basic services is OpenStack Compute (Nova). This service is installed on all cluster computer nodes. It manages the level of abstraction of virtual equipment (processors, memory, block devices, network adapters). Nova provides the management of instances of virtual machines addressing the hypervisor and giving such commands as it is launching and stopping.
My setup detail
/var/lib/glance
 due to which any partition used by /var
must have some free storage space for an instance to be created. Below is my setup snippet[root@compute-rhel ~]# lvs  LV  VG  Attr    LSize  Pool Origin Data% Meta% Move Log Cpy%Sync Convert  home rhel -wi-ao---- 134.49g  root rhel -wi-ao---- 50.00g  swap rhel -wi-ao---- 14.50g [root@compute-rhel ~]# pvs  PV     VG  Fmt Attr PSize  PFree  /dev/vda2 rhel lvm2 a-- <199.00g 4.00m [root@compute-rhel ~]# vgs  VG  #PV #LV #SN Attr  VSize  VFree  rhel  1  3  0 wz--n- <199.00g 4.00m [root@compute-rhel ~]# df -h Filesystem       Size Used Avail Use% Mounted on /dev/mapper/rhel-root  50G 2.3G  48G  5% / devtmpfs        15G   0  15G  0% /dev tmpfs          15G   0  15G  0% /dev/shm tmpfs          15G  17M  15G  1% /run tmpfs          15G   0  15G  0% /sys/fs/cgroup /dev/vda1       1014M 131M 884M 13% /boot /dev/mapper/rhel-home 135G  33M 135G  1% /home tmpfs         2.9G   0 2.9G  0% /run/user/0 [root@compute-rhel ~]# free -g        total    used    free   shared buff/cache  available Mem:       28      0     26      0      1     27 Swap:      14      0     14
Pre-requisite
Before you install OpenStack on CentOS 7, disable and stop the below services using the commands as shown.
# systemctl disable NetworkManager --now # systemctl disable firewalld --now # systemctl restart network # systemctl enable network
For RHEL 7 node: Register and subscribe to the necessary Red Hat channels as done for controller.
Before starting disable all the repos.
# subscription-manager repos --disable=*
Next enable all the required repos for to install OpenStack on RHEL 7
# subscription-manager repos --enable=rhel-7-server-rh-common-rpms Repository 'rhel-7-server-rh-common-rpms' is enabled for this system. # subscription-manager repos --enable=rhel-7-server-openstack-8-rpms Repository 'rhel-7-server-openstack-8-rpms' is enabled for this system. # subscription-manager repos --enable=rhel-7-server-extras-rpms Repository 'rhel-7-server-extras-rpms' is enabled for this system. # subscription-manager repos --enable=rhel-7-server-rpms Repository 'rhel-7-server-rpms' is enabled for this system.
Enable below repository to install OpenStack on CentOS 7 using Packstack
# yum install -y https://rdoproject.org/repos/rdo-release.rpm
Next install the openstack repository by installing the below rpm
# yum install -y centos-release-openstack-stein
Make sure the repository is enabled:
# yum-config-manager --enable openstack-stein
Step 4: Bring UP Controller VM
The Controller node is where most of the shared OpenStack services and other tools run. It supplies API, scheduling, and other shared services for the cloud.
I have already shared the configuration for my Virtual Machine. Since controller node will only host important openstack services hence we do not need too assign too much resource to this node.
My setup details
I will also create an additional volume group "cinder-volumes" to be used by the CINDER service. So make sure when you are creating the controller node, create one additional volume-group "
cinder-volumes
" with enough space, for me I have given 100GB which will be used for adding additional volume when launching Instance.Below is my setup snippet
[root@controller-rhel ~]# pvs  PV     VG       Fmt Attr PSize  PFree  /dev/vda3 rhel      lvm2 a--  <38.52g  <7.69g   /dev/vdb1 cinder-volumes lvm2 a-- <100.00g <100.00g [root@controller-rhel ~]# vgs  VG       #PV #LV #SN Attr  VSize  VFree  cinder-volumes  1  0  0 wz--n- <100.00g <100.00g  rhel       1  2  0 wz--n- <38.52g  <7.69g [root@controller-rhel ~]# lvs  LV   VG  Attr    LSize Pool  Origin Data% Meta% Move Log Cpy%Sync Convert  pool00 rhel twi-aotz-- 30.79g        15.04 11.48  root  rhel Vwi-aotz-- 30.79g pool00    15.04 [root@controller-rhel ~]# free -g        total    used    free   shared buff/cache  available Mem:       9      2      4      0      3      7 Swap:       0      0      0
Pre-requisite
The list of pre-requisites are same as done for Compute Node above.
Install Packstack
Now to Install OpenStack on CentOS 7 we need PackStack utility which you can install using yum
# yum install -y openstack-packstack
Next generate your answer file /root/answers.txt
and view the resulting file
# packstack --gen-answer-file ~/answer-file.txt
Now we are ready to create and modify our answers file to deploy openstack services on our controller and compute node
Step 5: Create answers file and Install Openstack
Below are the changes which I have done for my setup to install OpenStack on CentOS 7.
Next execute the packstack utility on the controller node to install OpenStack on CentOS 7 using the syntax as shown below
[root@controller-rhel ~]# packstack --answer-file /root/answers.txt
Welcome to the Packstack setup utility

If everything goes nice then you should see all GREEN and at the end of you will get the link to your dashboard (as highlighted). So this means our openstack installation on RHEL/CentOS 7 is complete.
-d
if you need to update the configuration.
Step 6: Check OpenStack service status
Install openstack-utils
to check the status of all the openstack services
# yum -y install openstack-utils
Next check the status
[root@controller-rhel ~]# openstack-status == Nova services == openstack-nova-api:           active openstack-nova-cert:          active openstack-nova-compute:         inactive (disabled on boot) openstack-nova-network:         inactive (disabled on boot) openstack-nova-scheduler:        active openstack-nova-conductor:        active == Glance services == openstack-glance-api:          active openstack-glance-registry:       active == Keystone service == openstack-keystone:           inactive (disabled on boot) == Horizon service == openstack-dashboard:          active == neutron services == neutron-server:             active neutron-dhcp-agent:           active neutron-l3-agent:            active neutron-metadata-agent:         active neutron-openvswitch-agent:       active == Cinder services == openstack-cinder-api:          active openstack-cinder-scheduler:       active openstack-cinder-volume:        active openstack-cinder-backup:        inactive (disabled on boot) == Support services == mysqld:                 unknown libvirtd:                active openvswitch:              active dbus:                  active target:                 active rabbitmq-server:            active memcached:               active == Keystone users == Warning keystonerc not sourced
ALSO READ:
Check Openstack version and mapped release information
Step 7: Source keystonerc file
Now once you install OpenStack on CentOS 7, next you can source your keystoncerc
file to get more detailed list of openstack-service
status. This keystonerc
file will be available at the home folder of the root user as shown below:
[root@controller-rhel ~]# ls -l keystonerc_admin -rw-------. 1 root root 229 Jul 7 22:57 keystonerc_admin [root@controller-rhel ~]# pwd /root [root@controller-rhel ~]# source keystonerc_admin
Next check the status of openstack services
[root@controller-rhel ~(keystone_admin)]# openstack-status == Nova services == openstack-nova-api:           active openstack-nova-cert:          active openstack-nova-compute:         inactive (disabled on boot) openstack-nova-network:         inactive (disabled on boot) openstack-nova-scheduler:        active openstack-nova-conductor:        active == Glance services == openstack-glance-api:          active openstack-glance-registry:       active == Keystone service == openstack-keystone:           inactive (disabled on boot) == Horizon service == openstack-dashboard:          active == neutron services == neutron-server:             active neutron-dhcp-agent:           active neutron-l3-agent:            active neutron-metadata-agent:         active neutron-openvswitch-agent:       active == Cinder services == openstack-cinder-api:          active openstack-cinder-scheduler:       active openstack-cinder-volume:        active openstack-cinder-backup:        inactive (disabled on boot) == Support services == mysqld:                 unknown libvirtd:                active openvswitch:              active dbus:                  active target:                 active rabbitmq-server:            active memcached:               active == Keystone users == +----------------------------------+---------+---------+-------------------+ |        id        |  name | enabled |    email    | +----------------------------------+---------+---------+-------------------+ | e97f18a9994e4b99bcc0e6fe8db95cd3 | admin |  True |  root@localhost | | dccbaca5e2ee4866b343573678ec3bf7 | cinder |  True | cinder@localhost | | 7dec80c93f8a4aafa1559a59e6bf606c | glance |  True | glance@localhost | | 778e4fbefdfa4329bf9b7143ce6ffe74 | neutron |  True | neutron@localhost | | e3d85ca8a8bb4ba5a9457712ce5814f5 |  nova |  True |  nova@localhost | +----------------------------------+---------+---------+-------------------+ == Glance images == +----+------+ | ID | Name | +----+------+ +----+------+ == Nova managed services == +----+------------------+------------------------+----------+---------+-------+----------------------------+-----------------+ | Id | Binary      | Host          | Zone   | Status | State | Updated_at         | Disabled Reason | +----+------------------+------------------------+----------+---------+-------+----------------------------+-----------------+ | 1 | nova-consoleauth | controller-rhel.example| internal | enabled | up  | 2018-07-07T18:02:59.000000 | -        | | 2 | nova-scheduler  | controller-rhel.example| internal | enabled | up  | 2018-07-07T18:03:00.000000 | -        | | 3 | nova-conductor  | controller-rhel.example| internal | enabled | up  | 2018-07-07T18:03:01.000000 | -        | | 4 | nova-cert    | controller-rhel.example| internal | enabled | up  | 2018-07-07T18:02:57.000000 | -        | | 5 | nova-compute   | compute-rhel.example  | nova   | enabled | up  | 2018-07-07T18:03:04.000000 | -        | +----+------------------+------------------------+----------+---------+-------+----------------------------+-----------------+ == Nova networks == +----+-------+------+ | ID | Label | Cidr | +----+-------+------+ +----+-------+------+ == Nova instance flavors == +----+-----------+-----------+------+-----------+------+-------+-------------+-----------+ | ID | Name   | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public | +----+-----------+-----------+------+-----------+------+-------+-------------+-----------+ | 1 | m1.tiny  | 512    | 1  | 0     |   | 1   | 1.0     | True   | | 2 | m1.small | 2048   | 20  | 0     |   | 1   | 1.0     | True   | | 3 | m1.medium | 4096   | 40  | 0     |   | 2   | 1.0     | True   | | 4 | m1.large | 8192   | 80  | 0     |   | 4   | 1.0     | True   | | 5 | m1.xlarge | 16384   | 160 | 0     |   | 8   | 1.0     | True   | +----+-----------+-----------+------+-----------+------+-------+-------------+-----------+ == Nova instances == +----+------+--------+------------+-------------+----------+ | ID | Name | Status | Task State | Power State | Networks | +----+------+--------+------------+-------------+----------+ +----+------+--------+------------+-------------+----------+
So as you see it gives me a detailed status of all the openstack services.
Step 8: Access OpenStack Horizon Dashboard
So now our OpenStack installation is complete using packstack on CentOS/RHEL 7 and we can see our services are also up and running properly. Finally now you can login to the horizon dashboard.
Lastly I hope the steps from the article to install OpenStack on CentOS 7 Linux was helpful. So, let me know your suggestions and feedback using the comment section.
Hey thank you for ur article ,
I actually have installed the packstack , and didnt at first use the answers file ,
I have 3 questions :
if the host of centos goes down , how do we start each time the service ?
and about the openstack-utils , I have a centos8 stream and the package couldnt be found for installation
else do you suggest any documentation to run new instances based on some image and to connect to them , thank you in advance 🙂
Hi Sir,
I want to deploy open stack with 2 controller nodes 2 network nodes and multiple compute nodes, could you please make an article on deploying openstack with 2 controller nodes
It is not possible to deploy openstack with more than 1 controller node using Packstack. You can try other ways of installation such as https://www.golinuxcloud.com/how-to-install-tripleo-undercloud-rhel-7/
Hi sir…I would like to know is it possible to change IP address of Openstack packstack deployed?, I would like to avoid from deployed it again based on new IP address. If it can be done, please advise which part should I change. My server port1 is connected to network 192.168.0.10/24. Deployment of Openstack is using 192.168.0.10 as the IP address, my horizon browser access also is via 192.168.0.10.
Now I want to connect the server port1 to network 172.16.100.90/24. I know that horizon IP should be change to 172.16.100.90 and for sure that’s not the only component that I need to change. Thus, what other component that I should change/update with the new IP and how it can be done.
Hi ,
I have already packstack running environment, but my many service has been corrupted and getting many issue.
Can I redeploy with same shared step ?
Or reinstall of packstack need any deletion or cleanup? Or simple I can run
packstack –answer-file /root/answer.txt
You can just go ahead and redeploy with
packstack –answer-file /root/answer.txt
. It will perform cleanup, but if your services are getting corrupted I would suggest to also check the system resources once.If you just wish to update the configuration then you can use
-d
with packstack[root@jwu ~]# sudo yum install -y openstack-packstack

Thank you for highlighting this. RHEL is just released and still has many open points and i doubt if their satellite server contains these dependencies. But nevertheless I will try to check if I can get a solution for you. In the meanwhile if you manage to find a working solution then please do share here.
