创建和启动虚拟机实例 安装Horizon
第一步：使用我们在系统中之前创建的新用户登录，让我们继续创建实例
[Hyman@theitroad ~(keystone)]# su - tech ##use your username [Hyman@theitroad ~]$ [Hyman@theitroad ~]$vim ~/keystonerc export OS_PROJECT_DOMAIN_NAME=default export OS_USER_DOMAIN_NAME=default export OS_PROJECT_NAME=helloworld #remember the project we had created export OS_USERNAME=penchant #remember the username we had created for the project export OS_PASSWORD=helloworld123 #remember the password we had created for the project export OS_AUTH_URL=http://192.168.122.130:5000/v3 export OS_IDENTITY_API_VERSION=3 export OS_IMAGE_API_VERSION=2 export PS1='[\Hyman@theitroad\h \W(keystone)]$'
[Hyman@theitroad ~]$chmod 600 ~/keystonerc [Hyman@theitroad ~]$source ~/keystonerc [Hyman@theitroad ~(keystone)]$echo "source ~/keystonerc " >> ~/.bash_profile
第二步：检查Flavors，网络和图像
[Hyman@theitroad ~(keystone)]$openstack flavor list +----+-------+-----+------+-----------+-------+-----------+ | ID | Name | RAM | Disk | Ephemeral | VCPUs | Is Public | +----+-------+-----+------+-----------+-------+-----------+ | 0 | Basic | 512 | 10 | 0 | 1 | True | +----+-------+-----+------+-----------+-------+-----------+
[Hyman@theitroad ~(keystone)]$openstack network list +--------------------------------------+-----------+--------------------------------------+ | ID | Name | Subnets | +--------------------------------------+-----------+--------------------------------------+ | e9927eb9-7467-4e7e-844a-fc07db9c9b85 | firstnet1 | 800efe16-5a49-40f9-8523-e43a48560650 | +--------------------------------------+-----------+--------------------------------------+
[Hyman@theitroad ~(keystone)]$openstack image list +--------------------------------------+---------+--------+ | ID | Name | Status | +--------------------------------------+---------+--------+ | c13fd621-0d74-4e8f-9481-5cbb02decbd3 | CentOS7 | active | +--------------------------------------+---------+--------+
第三步：为实例创建一个安全组，我们可以称之为"securegrooupone"部分的任何名称
[Hyman@theitroad ~(keystone)]$openstack security group create securegroupone +-----------------+-------------------------------------------------------------------------------------------------------------------------------------------------------+ | Field | Value | +-----------------+-------------------------------------------------------------------------------------------------------------------------------------------------------+ | created_at | 2019-03-14T10:41:10Z | | description | securegroupone | | id | 05e8cdf2-d59b-40fa-ad55-59d9a3c8af04 | | name | securegroupone | | project_id | f5547f8c879c41bea9c60e4541745c35 | | revision_number | 2 | | rules | created_at='2019-03-14T10:41:10Z', direction='egress', ethertype='IPv6', id='80d35496-b370-4699-ac7b-a55e96466d23', updated_at='2019-03-14T10:41:10Z' | | | created_at='2019-03-14T10:41:10Z', direction='egress', ethertype='IPv4', id='ddc1edd5-8ce2-411a-933c-acb1765d43b1', updated_at='2019-03-14T10:41:10Z' | | updated_at | 2019-03-14T10:41:10Z | +-----------------+-------------------------------------------------------------------------------------------------------------------------------------------------------+
第四步：创建一个用于连接到实例的SSH Keypair
[Hyman@theitroad ~(keystone)]$ssh-keygen -q -N "" Enter file in which to save the key (/home/tech/.ssh/id_rsa):
第五步：添加公钥
[Hyman@theitroad ~(keystone)]$openstack keypair create --public-key ~/.ssh/id_rsa.pub penchantkey +-------------+-------------------------------------------------+ | Field | Value | +-------------+-------------------------------------------------+ | fingerprint | b6:25:cb:6c:a6:ff:29:5b:4f:59:76:aa:d2:6e:0c:25 | | name | penchantkey | | user_id | 1e03edc140cf47858778ab44319391f6 | +-------------+-------------------------------------------------+
[Hyman@theitroad ~(keystone)]$netID=$(openstack network list | grep firstnet1 | awk '{ print }')
[Hyman@theitroad ~(keystone)]$openstack server create --flavor Basic --image CentOS7 --security-group securegroupone --nic net-id=$netID --key-name penchantkey Cent7 +-----------------------------+------------------------------------------------+ | Field | Value | +-----------------------------+------------------------------------------------+ | OS-DCF:diskConfig | MANUAL | | OS-EXT-AZ:availability_zone | | | OS-EXT-STS:power_state | NOSTATE | | OS-EXT-STS:task_state | scheduling | | OS-EXT-STS:vm_state | building | | OS-SRV-USG:launched_at | None | | OS-SRV-USG:terminated_at | None | | accessIPv4 | | | accessIPv6 | | | addresses | | | adminPass | SLpUbJgmuwd4 | | config_drive | | | created | 2019-03-14T10:53:50Z | | flavor | Basic (0) | | hostId | | | id | 37822ec3-7b4b-4354-bafe-76d1e34c90c2 | | image | CentOS7 (c13fd621-0d74-4e8f-9481-5cbb02decbd3) | | key_name | penchantkey | | name | Cent7 | | progress | 0 | | project_id | f5547f8c879c41bea9c60e4541745c35 | | properties | | | security_groups | name='05e8cdf2-d59b-40fa-ad55-59d9a3c8af04' | | status | BUILD | | updated | 2019-03-14T10:53:51Z | | user_id | 1e03edc140cf47858778ab44319391f6 | | volumes_attached | | +-----------------------------+------------------------------------------------+
[Hyman@theitroad ~(keystone)]$openstack server list +--------------------------------------+-------+--------+----------+---------+--------+ | ID | Name | Status | Networks | Image | Flavor | +--------------------------------------+-------+--------+----------+---------+--------+ | 37822ec3-7b4b-4354-bafe-76d1e34c90c2 | Cent7 | BUILD | | CentOS7 | Basic | +--------------------------------------+-------+--------+----------+---------+--------+
第六步：为我们创建的安全组配置安全设置，这将为我们提供SSH和ICMP
[Hyman@theitroad ~(keystone)]$openstack security group rule create --protocol icmp --ingress securegroupone +-------------------+--------------------------------------+ | Field | Value | +-------------------+--------------------------------------+ | created_at | 2019-03-14T15:17:04Z | | description | | | direction | ingress | | ether_type | IPv4 | | id | 43a93b70-0907-407f-a559-2be73a395cdd | | name | None | | port_range_max | None | | port_range_min | None | | project_id | f5547f8c879c41bea9c60e4541745c35 | | protocol | icmp | | remote_group_id | None | | remote_ip_prefix | 0.0.0.0/0 | | revision_number | 0 | | security_group_id | 05e8cdf2-d59b-40fa-ad55-59d9a3c8af04 | | updated_at | 2019-03-14T15:17:04Z | +-------------------+--------------------------------------+
第七步：允许SSH
[Hyman@theitroad ~(keystone)]$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 | +-------------------+--------------------------------------+

安装地平线
通过以下安装到root用户并跟进以进行地平线。
[Hyman@theitroad ~(keystone)]$sudo su [Hyman@theitroad ~(keystone)]# [Hyman@theitroad ~(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
继续配置Horizo n
[Hyman@theitroad ~(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': {

'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"
编辑如下所示仪表板的httpd文件：
[Hyman@theitroad ~(keystone)]# vim /etc/httpd/conf.d/openstack-dashboard.conf
# on about line 4: add the following lines
WSGIDaemonProcess dashboard
