Installing a Three-Node OpenStack Queens Cluster-Part 10

Create and launch Horizon’s virtual machine instance ad install

step 1: Sign in with the new user we created earlier in the system and continue to create the instance

[[email protected] ~(keystone)]# su - tech ##use your username [[email protected] ~]$ [[email protected] ~]$ vim ~/keystonerc export OS_PROJECT_DOMAIN_NAME=default export OS_USER_DOMAIN_NAME=default export OS_PROJECT_NAME=helloworld #remember the project we had created export OS_USERNAME=penchant   #remember the username we had created for the project export OS_PASSWORD=helloworld123 #remember the password we had created for the project export OS_AUTH_URL=http://192.168.122.130:5000/v3 export OS_IDENTITY_API_VERSION=3 export OS_IMAGE_API_VERSION=2 export PS1='[[email protected]h W(keystone)]$ '
[[email protected] ~]$ chmod 600 ~/keystonerc[[email protected] ~]$ source ~/keystonerc [[email protected] ~(keystone)]$ echo "source ~/keystonerc " >> ~/.bash_profile

The second step: Check available flavors, networks and images

[[email protected] ~(keystone)]$ openstack flavor list                          +----+-------+-----+------+-----------+-------+-----------+ | ID | Name  | RAM | Disk | Ephemeral | VCPUs | Is Public | +----+-------+-----+------+-----------+-------+-----------+ | 0  | Basic | 512 |   10 |         0 |     1 | True      | +----+-------+-----+------+-----------+-------+-----------+
[[email protected] ~(keystone)]$ openstack network list  +--------------------------------------+-----------+--------------------------------------+ | ID                                   | Name      | Subnets                              | +--------------------------------------+-----------+--------------------------------------+ | e9927eb9-7467-4e7e-844a-fc07db9c9b85 | firstnet1 | 800efe16-5a49-40f9-8523-e43a48560650 | +--------------------------------------+-----------+--------------------------------------+
[[email protected] ~(keystone)]$ openstack image list    +--------------------------------------+---------+--------+ | ID                                   | Name    | Status | +--------------------------------------+---------+--------+ | c13fd621-0d74-4e8f-9481-5cbb02decbd3 | CentOS7 | active | +--------------------------------------+---------+--------+

third step: Create a security group for the instance, you can name it anything in the “securegroupone” section

[[email protected] ~(keystone)]$ openstack security group create securegroupone +-----------------+-------------------------------------------------------------------------------------------------------------------------------------------------------+ | Field           | Value                                                                                                                                                 | +-----------------+-------------------------------------------------------------------------------------------------------------------------------------------------------+ | created_at      | 2019-03-14T10:41:10Z                                                                                                                                  | | description     | securegroupone                                                                                                                                        | | id              | 05e8cdf2-d59b-40fa-ad55-59d9a3c8af04                                                                                                                  | | name            | securegroupone                                                                                                                                        | | project_id      | f5547f8c879c41bea9c60e4541745c35                                                                                                                      | | revision_number | 2                                                                                                                                                     | | rules           | created_at='2019-03-14T10:41:10Z', direction='egress', ethertype='IPv6', id='80d35496-b370-4699-ac7b-a55e96466d23', updated_at='2019-03-14T10:41:10Z' | |                 | created_at='2019-03-14T10:41:10Z', direction='egress', ethertype='IPv4', id='ddc1edd5-8ce2-411a-933c-acb1765d43b1', updated_at='2019-03-14T10:41:10Z' | | updated_at      | 2019-03-14T10:41:10Z                                                                                                                                  | +-----------------+-------------------------------------------------------------------------------------------------------------------------------------------------------+

the fourth step: Create an SSH key pair to connect to the instance

[[email protected] ~(keystone)]$ ssh-keygen -q -N ""                                                               Enter file in which to save the key (/home/tech/.ssh/id_rsa):

the fifth step: Add public key

[[email protected] ~(keystone)]$ openstack keypair create --public-key ~/.ssh/id_rsa.pub penchantkey +-------------+-------------------------------------------------+ | Field       | Value                                           | +-------------+-------------------------------------------------+ | fingerprint | b6:25:cb:6c:a6:ff:29:5b:4f:59:76:aa:d2:6e:0c:25 | | name        | penchantkey                                     | | user_id     | 1e03edc140cf47858778ab44319391f6                | +-------------+-------------------------------------------------+
[[email protected] ~(keystone)]$ netID=$(openstack network list | grep firstnet1 | awk '{ print $2 }')

Step Six: Configure security settings for the security group you created above so that you can use SSH and ICMP

Go ahead and configure Horizon

[[email protected] ~(keystone)]# vim /etc/openstack-dashboard/local_settings# Jump to line 38 and add Dashboard Host depending on the domain name you require here ALLOWED_HOSTS = ['horizon.example.com', 'localhost'] #input your FQDN at horizon.example.com# on line 64: uncomment the lines to look like below OPENSTACK_API_VERSIONS = { "data-processing": 1.1,"identity": 3, "volume": 2, "compute": 2, }# on line 75: uncomment, edit as shown OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True# uncomment line 97 as shown below OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = 'Default'# on about line 167 and 168: change the IP and add Memcache server to your own CACHES = {     'default': {         'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',         'LOCATION': '192.168.122.130:11211',     }, }# on the line 189: change OPENSTACK_HOST to the ip of your host OPENSTACK_HOST = "192.168.122.130" OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST OPENSTACK_KEYSTONE_DEFAULT_ROLE = "member"

Edit the dashboard’s httpd file as follows:

[[email protected] ~(keystone)]# vim /etc/httpd/conf.d/openstack-dashboard.conf# on about line 4: add the following lines WSGIDaemonProcess dashboard WSGIProcessGroup dashboard WSGISocketPrefix run/wsgi WSGIApplicationGroup %{GLOBAL}

Access the dashboard through a web browser by entering the URL under http: // (here, enter the hostname or IP address of the server) / dashboard /

Then you go. On the dashboard, you can create additional images, create networks, subnets, launch instances, and more. This is a successful journey and we want to thank you for continuing to the end.
