Openstack-M版部署一nova计算服务（控制节点）

1.安装nova服务所需的包

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

2.创建数据库

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)]> CREATE DATABASE nova_api;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> 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)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \
-> IDENTIFIED BY '000000';
Query OK, 0 rows affected (0.02 sec)

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY '000000';
Query OK, 0 rows affected (0.00 sec)
MariaDB [nova_api]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \
-> IDENTIFIED BY '000000';
Query OK, 0 rows affected (0.06 sec)

MariaDB [nova_api]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY '000000';
Query OK, 0 rows affected (0.00 sec)
2.4退出数据库
MariaDB [(none)]> exit
Bye

3.创建服务实体和API端点

4.修改配置文件/etc/nova/nova.conf

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] #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

5.同步数据库

[root@controller ~]# su -s /bin/sh -c "nova-manage api_db sync" nova
[root@controller ~]# su -s /bin/sh -c "nova-manage db sync" nova
/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.")
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.")
result = self._query(query)

6.启动nova服务，并设置开机自启动

[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.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-consoleauth.service to /usr/lib/systemd/system/openstack-nova-consoleauth.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-scheduler.service to /usr/lib/systemd/system/openstack-nova-scheduler.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-conductor.service to /usr/lib/systemd/system/openstack-nova-conductor.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-novncproxy.service to /usr/lib/systemd/system/openstack-nova-novncproxy.service.

[root@controller ~]# systemctl start openstack-nova-api.service \
openstack-nova-consoleauth.service openstack-nova-scheduler.service \
openstack-nova-conductor.service openstack-nova-novncproxy.service

7.验证操作

[root@controller ~]# nova service-list
+----+------------------+------------+----------+---------+-------+----------------------------+-----------------+
| Id | Binary | Host | Zone | Status | State | Updated_at | Disabled Reason |
+----+------------------+------------+----------+---------+-------+----------------------------+-----------------+
| 1 | nova-consoleauth | controller | internal | enabled | up | 2018-06-29T04:41:44.000000 | - |
| 2 | nova-conductor | controller | internal | enabled | up | 2018-06-29T04:41:44.000000 | - |
| 3 | nova-scheduler | controller | internal | enabled | up | 2018-06-29T04:41:44.000000 | - |
+----+------------------+------------+----------+---------+-------+----------------------------+-----------------+
