onva控制节点部署

第一步：创建nova的库
[root@zxw6 ~]# mysql -uroot -p123
create database nova_api;

create database nova;

create database nova_cell0;

第二步：给予权限设置远程登录
MariaDB [mysql]> grant all on nova_api.* to 'nova'@'localhost' identified by 'zxw6';
Query OK, 0 rows affected (0.01 sec)
MariaDB [mysql]> grant all on nova_api.* to 'nova'@'%' identified by 'zxw6';
Query OK, 0 rows affected (0.00 sec)

MariaDB [mysql]> grant all on nova.* to 'nova'@'%' identified by 'zxw6';
Query OK, 0 rows affected (0.00 sec)
MariaDB [mysql]> grant all on nova.* to 'nova'@'localhost' identified by 'zxw6';
Query OK, 0 rows affected (0.00 sec)

MariaDB [mysql]> grant all on nova_cell0.* to 'nova'@'localhost' identified by 'zxxw6';
Query OK, 0 rows affected (0.00 sec)
MariaDB [mysql]> grant all on nova_cell0.* to 'nova'@'%' identified by 'zxw6';
Query OK, 0 rows affected (0.00 sec)

登录到openstack
source openrc
第三步：创建nova用户
[root@zxw6 ~]# openstack user create --domain default --password=zxw6 nova

第四步：在service项目把nova用户添加到admin角色
[root@zxw6 ~]# openstack role add --project service --user nova admin

第五步：创建服务
[root@zxw6 ~]# openstack service create --name nova
--description "OpenStack Compute" compute

第六步：创建服务端点
[root@zxw6 ~]# openstack endpoint create --region RegionOne compute public http://zxw6:8774/v2.1

[root@zxw6 ~]# openstack endpoint create --region RegionOne compute internal http://zxw6:8774/v2.1

[root@zxw6 ~]# openstack endpoint create --region RegionOne
compute admin http://zxw6:8774/v2.1

第七步：创建用户placement （检查资源）
[root@zxw6 ~]# openstack user create --domain default --password=zxw6 placement

第八步：在service项目把placement用户添加到admin角色
[root@zxw6 ~]# openstack role add --project service --user placement admin

 

第九步：创建服务
[root@zxw6 ~]# openstack service create --name placement --description "Placement API" placement

第十步：创建端点服务
[root@zxw6 ~]# openstack endpoint create --region RegionOne placement public http://zxw6:8778

[root@zxw6 ~]# openstack endpoint create --region RegionOne placement internal http://zxw6:8778

[root@zxw6 ~]# openstack endpoint create --region RegionOne placement admin http://zxw6:8778

第十一步：安装nova软件包

[root@zxw6 ~]# yum install openstack-nova-api openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler openstack-nova-placement-api -y

第十二步：编辑nova配置文件
[root@zxw6 ~]# vim /etc/nova/nova.conf

[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:zxw6@zxw6 传输协议
my_ip = 192.168.126.6 节点ip
use_neutron = True 使用网络组件
firewall_driver = nova.virt.firewall.NoopFirewallDriver 开启防火墙的驱动

[api_database]
connection = mysql+pymysql://nova:zxw6@zxw6/nova_api api数据库的链接

[database]
connection = mysql+pymysql://nova:zxw6@zxw6/nova nova数据库的链接

[api]
auth_strategy = keystone 认证方式

[keystone_authtoken]
auth_uri = http://zxw6:5000
auth_url = http://zxw6:35357
memcached_servers = zxw6:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = zxw6

[vnc]
enabled = true 开启vnc
vncserver_listen = $my_ipvncserver_proxyclient_address = $my_ip
vncserver_proxyclient_address = $my_ip 监听变量

[glance]
api_servers = http://zxw6:9292 镜像地址

[oslo_concurrency]
lock_path = /var/lib/nova/tmp 零时文件保存目录

[placement]
os_region_name = RegionOne 工作域
project_domain_name = Default 域
project_name = service 工作项目
auth_type = password 认证方式
user_domain_name = Default
auth_url = http://zxw6:35357/v3 认证路径
username = placement
password = zxw6

第十三步：编辑配置文件httpd
[root@zxw6 ~]# vim /etc/httpd/conf.d/00-nova-placement-api.conf
<Directory /usr/bin>
<IfVersion >= 2.4>
Require all granted
</IfVersion>
<IfVersion < 2.4>
Order allow,deny
Allow from all
</IfVersion>
</Directory>

第十四步：重启http服务
[root@zxw6 ~]# systemctl restart httpd

第十五步：导入nova_api的库
[root@zxw6 ~]# su -s /bin/sh -c "nova-manage api_db sync" nova

第十六步：导入nova_cell0的库
[root@zxw6 ~]# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
认证
[root@zxw6 ~]# su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
6db3fa34-9498-4b1f-8042-90bba954fa48

第十七步：同步nova的库
root@zxw6 ~]# su -s /bin/sh -c "nova-manage db sync" nova

第十八步：查看cell的列表
[root@zxw6 ~]# nova-manage cell_v2 list_cells

+-------+--------------------------------------+
| Name | UUID |
+-------+--------------------------------------+
| cell0 | 00000000-0000-0000-0000-000000000000 |
| cell1 | 6db3fa34-9498-4b1f-8042-90bba954fa48 |
+-------+--------------------------------------+

第十九步：从其nova所有的服务并开机自启
[root@zxw6 ~]# systemctl start openstack-nova-api.service
openstack-nova-consoleauth.service openstack-nova-scheduler.service
openstack-nova-conductor.service openstack-nova-novncproxy.service

[root@zxw6 ~]# systemctl enable openstack-nova-api.service
openstack-nova-consoleauth.service openstack-nova-scheduler.service
openstack-nova-conductor.service openstack-nova-novncproxy.service

[root@zxw6 ~]# systemctl status openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service | grep active
Active: active (running) since 三 2019-07-31 18:25:03 CST; 9min ago
Active: active (running) since 三 2019-07-31 18:25:00 CST; 9min ago

openstack-nova-api.service 负责接收和响应客户
openstack-nova-consoleauth.service 负责对访问虚拟机控制台提供token认证
openstack-nova-scheduler.service 负责访问调度器
openstack-nova-conductor.service 负责访问数据库
openstack-nova-novncproxy.service 负责web浏览器vnc的访问
