分手后的思念是犯贱 2022-05-21 05:13 268阅读 0赞

**1.安装nova服务所需的包**

<table> 
 <tbody> 
 <tr> 
 <td>[root@controller ~]# yum install openstack-nova-api openstack-nova-conductor &nbsp; \ openstack-nova-console openstack-nova-novncproxy &nbsp; openstack-nova-scheduler -y </td> 
 </tr> 
 </tbody> 
</table>

**2.创建数据库**

<table> 
 <tbody> 
 <tr> 
 <td>2.1登录数据库 [root@controller ~]# mysql -u root -p000000 2.2创建nova，nova_api数据库 MariaDB [(none)]&gt; CREATE DATABASE nova_api; Query OK, 1 row affected (0.00 sec) MariaDB [(none)]&gt; CREATE DATABASE nova; Query OK, 1 row affected (0.00 sec) 2.3授予nova用户对nova，nova_api数据库的访问权限（000000为密码） MariaDB [(none)]&gt; GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \ &nbsp; &nbsp; -&gt; &nbsp; IDENTIFIED BY '000000'; Query OK, 0 rows affected (0.02 sec) MariaDB [(none)]&gt; GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' &nbsp; &nbsp;IDENTIFIED BY '000000'; Query OK, 0 rows affected (0.00 sec) MariaDB [nova_api]&gt; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \ &nbsp; &nbsp; -&gt; &nbsp; IDENTIFIED BY '000000'; Query OK, 0 rows affected (0.06 sec) MariaDB [nova_api]&gt; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' &nbsp; &nbsp;IDENTIFIED BY '000000'; &nbsp; &nbsp;&nbsp; Query OK, 0 rows affected (0.00 sec) 2.4退出数据库 MariaDB [(none)]&gt; exit Bye </td> 
 </tr> 
 </tbody> 
</table>

**3.创建服务实体和API端点**

<table> 
 <tbody> 
 <tr>

**4.修改配置文件/etc/nova/nova.conf**

<table> 
 <tbody> 
 <tr> 
 <td>vim /etc/nova/nova.conf 1 [DEFAULT] 2 enabled_apis = osapi_compute,metadata#启用计算api,元数据api 3 rpc_backend = rabbit#消息队列的类型 4 auth_strategy = keystone 5 my_ip = 10.0.10.130 #控制节点管理IP 6 use_neutron = True#启动对网络服务的支持 7 firewall_driver = nova.virt.firewall.NoopFirewallDriver 2161 [api_database] &nbsp;#配置数据库访问 2162 connection = mysql+pymysql://nova:000000@controller/nova_api 3107 [database] 3108 connection = mysql+pymysql://nova:000000@controller/nova 3329 [glance]#配置glance 服务的位置 3330 api_servers = http://controller:9292 3526 [keystone_authtoken]#配置身份访问服务 3527 auth_uri = http://controller:5000 3528 auth_url = http://controller:35357 3529 memcached_servers = controller:11211 3530 auth_type = password 3531 project_domain_name = default 3532 user_domain_name = default 3533 project_name = service 3534 username = nova 3535 password = 000000 4300 [oslo_concurrency]#锁定路径 4301 lock_path = /var/lib/nova/tmp 4398 [oslo_messaging_rabbit]#配置消息队列访问 4399 rabbit_host = controller 4400 rabbit_userid = openstack 4401 rabbit_password = 000000 5367 [vnc]#使用控制器节点的管理接口IP地址 5368 vncserver_listen = $my_ip 5369 vncserver_proxyclient_address = $my_ip </td> 
 </tr> 
 </tbody> 
</table>

**5.同步数据库**

<table> 
 <tbody> 
 <tr> 
 <td>[root@controller ~]# &nbsp;su -s /bin/sh -c "nova-manage api_db sync" nova [root@controller ~]# su -s /bin/sh -c "nova-manage db sync" nova &nbsp; &nbsp;&nbsp; /usr/lib/python2.7/site-packages/pymysql/cursors.py:170: Warning: (1831, u"Duplicate index 'block_device_mapping_instance_uuid_virtual_name_device_name_idx' defined on the table 'nova.block_device_mapping'. This is deprecated and will be disallowed in a future release.") &nbsp; result = self._query(query) /usr/lib/python2.7/site-packages/pymysql/cursors.py:170: Warning: (1831, u"Duplicate index 'uniq_instances0uuid' defined on the table 'nova.instances'. This is deprecated and will be disallowed in a future release.") &nbsp; result = self._query(query) </td> 
 </tr> 
 </tbody> 
</table>

**6.启动nova服务，并设置开机自启动**

<table> 
 <tbody> 
 <tr> 
 <td>[root@controller ~]# systemctl enable openstack-nova-api.service \ openstack-nova-consoleauth.service openstack-nova-scheduler.service \ openstack-nova-conductor.service openstack-nova-novncproxy.service Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-api.service to /usr/lib/systemd/system/openstack-nova-api.service.

 </tr> 
 </tbody> 
</table>

**7.验证操作**
