Create and Start Virtual Machine Instance ad Installation of Horizon
Step One: Log in with a new user we created earlier in the system and let us get going on with creating an 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='[\u@\h \W(keystone)]\$ '
[[email protected] ~]$ chmod 600 ~/keystonerc [[email protected] ~]$ source ~/keystonerc [[email protected] ~(keystone)]$ echo "source ~/keystonerc " >> ~/.bash_profile
Step Two: Check the flavors, network and images available
[[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 | +--------------------------------------+---------+--------+
Step Three: Create a security group for the instances, you can call it any name for “securegroupone” part
[[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 | +-----------------+-------------------------------------------------------------------------------------------------------------------------------------------------------+
Step Four: Create a SSH keypair that will be used for connecting to instances
[[email protected] ~(keystone)]$ ssh-keygen -q -N "" Enter file in which to save the key (/home/tech/.ssh/id_rsa):
Step Five: 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 $2 ')
[[email protected] ~(keystone)]$ openstack server create --flavor Basic --image CentOS7 --security-group securegroupone --nic net-id=$netID --key-name penchantkey Cent7 +-----------------------------+------------------------------------------------+ | Field | Value | +-----------------------------+------------------------------------------------+ | OS-DCF:diskConfig | MANUAL | | OS-EXT-AZ:availability_zone | | | OS-EXT-STS:power_state | NOSTATE | | OS-EXT-STS:task_state | scheduling | | OS-EXT-STS:vm_state | building | | OS-SRV-USG:launched_at | None | | OS-SRV-USG:terminated_at | None | | accessIPv4 | | | accessIPv6 | | | addresses | | | adminPass | SLpUbJgmuwd4 | | config_drive | | | created | 2019-03-14T10:53:50Z | | flavor | Basic (0) | | hostId | | | id | 37822ec3-7b4b-4354-bafe-76d1e34c90c2 | | image | CentOS7 (c13fd621-0d74-4e8f-9481-5cbb02decbd3) | | key_name | penchantkey | | name | Cent7 | | progress | 0 | | project_id | f5547f8c879c41bea9c60e4541745c35 | | properties | | | security_groups | name='05e8cdf2-d59b-40fa-ad55-59d9a3c8af04' | | status | BUILD | | updated | 2019-03-14T10:53:51Z | | user_id | 1e03edc140cf47858778ab44319391f6 | | volumes_attached | | +-----------------------------+------------------------------------------------+
[[email protected] ~(keystone)]$ openstack server list +--------------------------------------+-------+--------+----------+---------+--------+ | ID | Name | Status | Networks | Image | Flavor | +--------------------------------------+-------+--------+----------+---------+--------+ | 37822ec3-7b4b-4354-bafe-76d1e34c90c2 | Cent7 | BUILD | | CentOS7 | Basic | +--------------------------------------+-------+--------+----------+---------+--------+
Step Six: Configure security settings for the security group you created above that will give you the ability SSH and ICMP
[[email protected] ~(keystone)]$ openstack security group rule create --protocol icmp --ingress securegroupone +-------------------+--------------------------------------+ | Field | Value | +-------------------+--------------------------------------+ | created_at | 2019-03-14T15:17:04Z | | description | | | direction | ingress | | ether_type | IPv4 | | id | 43a93b70-0907-407f-a559-2be73a395cdd | | name | None | | port_range_max | None | | port_range_min | None | | project_id | f5547f8c879c41bea9c60e4541745c35 | | protocol | icmp | | remote_group_id | None | | remote_ip_prefix | 0.0.0.0/0 | | revision_number | 0 | | security_group_id | 05e8cdf2-d59b-40fa-ad55-59d9a3c8af04 | | updated_at | 2019-03-14T15:17:04Z | +-------------------+--------------------------------------+
Step Seven: Allow SSH
[[email protected] ~(keystone)]$ openstack security group rule create --protocol tcp --dst-port 22:22 securegroupone +-------------------+--------------------------------------+ | Field | Value | +-------------------+--------------------------------------+ | created_at | 2019-03-14T15:17:36Z | | description | | | direction | ingress | | ether_type | IPv4 | | id | 39f53276-e0c4-4955-8caa-0a62f52a06cd | | name | None | | port_range_max | 22 | | port_range_min | 22 | | project_id | f5547f8c879c41bea9c60e4541745c35 | | protocol | tcp | | remote_group_id | None | | remote_ip_prefix | 0.0.0.0/0 | | revision_number | 0 | | security_group_id | 05e8cdf2-d59b-40fa-ad55-59d9a3c8af04 | | updated_at | 2019-03-14T15:17:36Z | +-------------------+--------------------------------------+
List the created group rule
[[email protected] ~(keystone)]$ openstack security group rule list +--------------------------------------+-------------+-----------+------------+--------------------------------------+--------------------------------------+ | ID | IP Protocol | IP Range | Port Range | Remote Security Group | Security Group | +--------------------------------------+-------------+-----------+------------+--------------------------------------+--------------------------------------+ | 39f53276-e0c4-4955-8caa-0a62f52a06cd | tcp | 0.0.0.0/0 | 22:22 | None | 05e8cdf2-d59b-40fa-ad55-59d9a3c8af04 | | 3f2d46e5-3ca5-4b0f-b263-e09d27184707 | None | None | | None | 4ca419b0-6e49-49ad-a365-b3fda3f409e1 | | 43a93b70-0907-407f-a559-2be73a395cdd | icmp | 0.0.0.0/0 | | None | 05e8cdf2-d59b-40fa-ad55-59d9a3c8af04 | | 6c80f5c1-be37-431d-ac6f-323d959e8ce2 | None | None | | 4ca419b0-6e49-49ad-a365-b3fda3f409e1 | 4ca419b0-6e49-49ad-a365-b3fda3f409e1 | | 80d35496-b370-4699-ac7b-a55e96466d23 | None | None | | None | 05e8cdf2-d59b-40fa-ad55-59d9a3c8af04 | | 9f71dd53-cf8a-4871-b404-a4ab9c429958 | None | None | | 4ca419b0-6e49-49ad-a365-b3fda3f409e1 | 4ca419b0-6e49-49ad-a365-b3fda3f409e1 | | ddc1edd5-8ce2-411a-933c-acb1765d43b1 | None | None | | None | 05e8cdf2-d59b-40fa-ad55-59d9a3c8af04 | | e998a70b-4cf4-48cd-ab3d-23e5c195b633 | None | None | | None | 4ca419b0-6e49-49ad-a365-b3fda3f409e1 | +--------------------------------------+-------------+-----------+------------+--------------------------------------+--------------------------------------+
Install Horizon
Head over to the root user and follow through the following to have Horizon installed.
[[email protected] ~(keystone)]$ sudo su - [[email protected] ~(keystone)]# [[email protected] ~(keystone)]# yum --enablerepo=centos-openstack-queens,epel -y install openstack-dashboard Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile base: mirror.ucu.ac.ug centos-qemu-ev: mirror.ucu.ac.ug extras: mirror.ucu.ac.ug updates: mirror.ucu.ac.ug base | 3.6 kB 00:00:00 centos-ceph-luminous | 2.9 kB 00:00:00 centos-openstack-queens | 2.9 kB 00:00:00 centos-qemu-ev | 2.9 kB 00:00:00 extras | 3.4 kB 00:00:00 updates | 3.4 kB 00:00:00 Resolving Dependencies --> Running transaction check ---> Package openstack-dashboard.noarch 1:13.0.1-1.el7 will be installed
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 httpd file for dashboard like below:
[[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 to your dashboard via a web browser by inputting the URL below
http://(input server’s hostname or IP address here)/dashboard/
And there you go. On the dashboard, you can create other images, create networks, subnets, launch instances and many more. It has been a successful journey and we would wish to thank you for following through to the end.
