Preparatory:

We deactivate the NetworkManager service and the firewall

systemctl disable firewalld

systemctl stop firewalld

systemctl disable NetworkManager

systemctl stop NetworkManager

We start the Network service

systemctl enable network

systemctl start network

Facility:

We update the system and install the repositories

yum -y update

yum install -y centos-release-openstack-mitaka

Once the repositories have been updated and activated, we proceed to install openstack

yum install -y openstack-packstack

Taking into account that we are going to carry out a basic installation, as a laboratory test we install all the Packs

packstack –allinone

Once installed through our browser we access the URL http://192.168.1.200/dashboard

We can see the access username and password in the file: /root/keystonerc_admin

cat /root/keystonerc_admin

unset OS_SERVICE_TOKEN

export OS_USERNAME=admin

export OS_PASSWORD=f314d819965e4ec8
