launch centos7 vm from vagrant
Assume you use msys/cygwin shell on win or shell on OSX, we download centos7 Vagrant template and customized to vm for one single vm node openstack test.
- vm hostname: ctopenstack
- vm cpu: 2
- vm memory: 6GB
- 1 NIC: NAT
- 2 NIC: hostonly 10.120.0.21
mkdir -p vagrant/ctopenstack cd vagrant/ctopenstack curl -LO https://raw.githubusercontent.com/robertluwang/cloud-hands-on-guide/master/dc-vagrant-cloud/ctopenstack/Vagrantfile
here is Vagrantfile for our test,
Vagrant.configure("2") do |config|
config.vm.box="dreamcloud/centos7"
config.ssh.insert_key = false
config.vm.box_check_update = false
config.vm.define "ctopenstack" do |ct7|
ct7.vm.hostname = "ctopenstack"
ct7.vm.network :private_network, ip: "10.120.0.21"
ct7.vm.provider :virtualbox do |vb|
vb.customize ["modifyvm", :id, "--natdnshostresolver1", "off"]
vb.name="ctopenstack"
vb.memory=6144
vb.cpus=2
end
end
end
then start it up
vagrant up vagrant ssh
There are 2 NIC up now, enp0s3 for NAT, internet access, enp0s8 hostonly for private network, used for openstack later.

install openstack using packstack
This is official doc for packstack deploy.

step 1 Software repositories
$ sudo yum install -y centos-release-openstack-pike $ yum-config-manager --enable openstack-pike $ sudo yum update -y
step 2 Install Packstack Installer
$ sudo yum install -y openstack-packstack
Step 3 Run Packstack to install OpenStack
before run packstack, we need to give correct private network ip for openstack, by default packstack will take first NIC which is NAT ip for my case, but I prefer 2nd NIC hostonly ip as openstack admin ip, to allow local host access to it for example dashboard GUI.
first of all need to generate config file by,
sudo packstack --gen-answer-file=packstack_date +"%Y-%m-%d".conf
we replaced NIC ip with hostonly ip manually,
[vagrant@ctopenstack ~]$ cat packstack_2018-01-20.conf |grep 10.0.2.15 CONFIG_CONTROLLER_HOST=10.0.2.15 CONFIG_COMPUTE_HOSTS=10.0.2.15 CONFIG_NETWORK_HOSTS=10.0.2.15 CONFIG_STORAGE_HOST=10.0.2.15 CONFIG_SAHARA_HOST=10.0.2.15 CONFIG_AMQP_HOST=10.0.2.15 CONFIG_MARIADB_HOST=10.0.2.15 CONFIG_KEYSTONE_LDAP_URL=ldap://10.0.2.15 CONFIG_REDIS_HOST=10.0.2.15 [vagrant@ctopenstack ~]$ sed -i 's/10.0.2.15/10.120.0.21/g' packstack_2018-01-20.conf [vagrant@ctopenstack ~]$ cat packstack_2018-01-20.conf |grep 10.0.2.15 [vagrant@ctopenstack ~]$ cat packstack_2018-01-20.conf |grep 10.120.0.21 CONFIG_CONTROLLER_HOST=10.120.0.21 CONFIG_COMPUTE_HOSTS=10.120.0.21 CONFIG_NETWORK_HOSTS=10.120.0.21 CONFIG_STORAGE_HOST=10.120.0.21 CONFIG_SAHARA_HOST=10.120.0.21 CONFIG_AMQP_HOST=10.120.0.21 CONFIG_MARIADB_HOST=10.120.0.21 CONFIG_KEYSTONE_LDAP_URL=ldap://10.120.0.21 CONFIG_REDIS_HOST=10.120.0.21
now we can start to run packstack with own config file, it took around one hour to finish,
[vagrant@ctopenstack ~]$ sudo packstack --answer-file packstack_2018-01-20.conf Welcome to the Packstack setup utility The installation log file is available at: /var/tmp/packstack/20180120-223943-9e5pVY/openstack-setup.log Installing: Clean Up [ DONE ] Discovering ip protocol version [ DONE ] Setting up ssh keys [ DONE ] Preparing servers [ DONE ] Pre installing Puppet and discovering hosts' details [ DONE ] Preparing pre-install entries [ DONE ] Setting up CACERT [ DONE ] Preparing AMQP entries [ DONE ] Preparing MariaDB entries [ DONE ] Fixing Keystone LDAP config parameters to be undef if empty[ DONE ] Preparing Keystone entries [ DONE ] Preparing Glance entries [ DONE ] Checking if the Cinder server has a cinder-volumes vg[ DONE ] Preparing Cinder entries [ DONE ] Preparing Nova API entries [ DONE ] Creating ssh keys for Nova migration [ DONE ] Gathering ssh host keys for Nova migration [ DONE ] Preparing Nova Compute entries [ DONE ] Preparing Nova Scheduler entries [ DONE ] Preparing Nova VNC Proxy entries [ DONE ] Preparing OpenStack Network-related Nova entries [ DONE ] Preparing Nova Common entries [ DONE ] Preparing Neutron LBaaS Agent entries [ DONE ] Preparing Neutron API entries [ DONE ] Preparing Neutron L3 entries [ DONE ] Preparing Neutron L2 Agent entries [ DONE ] Preparing Neutron DHCP Agent entries [ DONE ] Preparing Neutron Metering Agent entries [ DONE ] Checking if NetworkManager is enabled and running [ DONE ] Preparing OpenStack Client entries [ DONE ] Preparing Horizon entries [ DONE ] Preparing Swift builder entries [ DONE ] Preparing Swift proxy entries [ DONE ] Preparing Swift storage entries [ DONE ] Preparing Gnocchi entries [ DONE ] Preparing Redis entries [ DONE ] Preparing Ceilometer entries [ DONE ] Preparing Aodh entries [ DONE ] Preparing Puppet manifests [ DONE ] Copying Puppet modules and manifests [ DONE ] Applying 10.120.0.21_controller.pp 10.120.0.21_controller.pp: [ DONE ] Applying 10.120.0.21_network.pp 10.120.0.21_network.pp: [ DONE ] Applying 10.120.0.21_compute.pp 10.120.0.21_compute.pp: [ DONE ] Applying Puppet manifests [ DONE ] Finalizing [ DONE ] **** Installation completed successfully ****** Additional information: * Time synchronization installation was skipped.

you can open another ssh session to monitor the packstack installation progress during installation,
tail -f /var/tmp/packstack/latest/openstack-setup.log
launch openstack dashboard GUI
You can get admin password from keystonerc_admin,
[vagrant@ctopenstack ~]$ sudo cat /root/keystonerc_admin
unset OS_SERVICE_TOKEN
export OS_USERNAME=admin
export OS_PASSWORD='2992c7dd428e4f4e'
export OS_AUTH_URL=http://10.120.0.21:5000/v3
export PS1='[\u@\h \W(keystone_admin)]\$ '
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_IDENTITY_API_VERSION=3
verify dashboard url,
[vagrant@ctopenstack ~]$ curl http://10.120.0.21:5000/v3
{"version": {"status": "stable", "updated": "2017-02-22T00:00:00Z", "media-types": [{"base": "application/json", "type": "application/vnd.openstack.identity-v3+json"}], "id": "v3.8", "links": [{"href": "http://10.120.0.21:5000/v3/", "rel": "self"}]}}[vagrant@ctopenstack ~]$
from local browser, type in http://10.120.0.21/dashboard.
Until now the one single node centos7 openstack ready to go!
lazy setup one vm node openstack using vagrant
If you feel boring to run above setup and script, I provide a ready to go Vagrantfile, you can launch a one node openstack box automatically.
mkdir -p vagrant/ctopenstack cd vagrant/ctopenstack curl -Lo Vagrantfile https://raw.githubusercontent.com/robertluwang/cloud-hands-on-guide/master/dc-vagrant-cloud/ctopenstack/Vagrantfile.pack
then openstack box ready for you!
If you like it, don’t mind to give a star :)
