- 安装并配置控制节点
1.数据库的配置
（1）以 root 用户连接到数据库服务器
[root@controller ~]# mysql -p
Enter password:
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 37
Server version: 10.1.20-MariaDB MariaDB Server
Copyright © 2000, 2016, Oracle, MariaDB Corporation Ab and others.
Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the current input statement.
(2)创建 nova_api 和 nova 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)
(3)对两个数据库进行正确的授权：
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \
-> IDENTIFIED BY 'nova';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'nova'; Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \
-> IDENTIFIED BY 'nova';
Query OK, 0 rows affected (0.01 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'nova';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> exit
Bye
2.创建 nova 用户
[root@controller ~]# openstack user create --domain default --password nova nova
+-----------+----------------------------------+
| Field | Value |
+-----------+----------------------------------+
| domain_id | 63a9992134eb452da1c8d950231c2b06 |
| enabled | True |
| id | 067877547f764797a4ea7c410afaadc8 |
| name | nova |
+-----------+----------------------------------+
3.给 nova 用户添加 admin 角色：
[root@controller ~]# openstack role add --project service --user nova admin
4.创建 nova 服务实体
[root@controller ~]# openstack service create --name nova \
> --description "OpenStack Compute" compute
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Compute |
| enabled | True |

> openstack-nova-scheduler
7.编辑/etc/nova/nova.conf文件
[root@controller ~]# vim /etc/nova/nova.conf
[DEFAULT]
enabled_apis = osapi_compute,metadata ##只启用计算和元数据API
rpc_backend = rabbit ##配置 “RabbitMQ” 消息队列访问
auth_strategy = keystone ##配置认证服务访问
my_ip = 172.25.43.1 ## 来使用控制节点的管理接口的IP 地址
use_neutron = True ##使能 Networking 服务
firewall_driver = nova.virt.firewall.NoopFirewallDriver
[api_database] ##配置数据库的连接
connection = mysql+pymysql://nova:nova@controller/nova_api
[database] ##配置数据库的连接
connection = mysql+pymysql://nova:nova@controller/nova
[oslo_messaging_rabbit] ##配置 “RabbitMQ” 消息队列访问
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = openstack
[keystone_authtoken] ##配置认证服务访问
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = nova
[vnc] ##配置VNC代理使用控制节点的管理接口IP地址
vncserver_listen = $my_ip
vncserver_proxyclient_address = $my_ip
[glance] ##配置镜像服务 API 的位置
api_servers = http://controller:9292
[oslo_concurrency] ##配置锁路径
lock_path = /var/run/nova/tmp
8.同步Compute 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:166: Warning: (1831, u'Duplicate index `block_device_mapping_instance_uuid_virtual_name_device_name_idx`. This is deprecated and will be disallowed in a future release.')
result = self._query(query)
/usr/lib/python2.7/site-packages/pymysql/cursors.py:166: Warning: (1831, u'Duplicate index `uniq_instances0uuid`. This is deprecated and will be disallowed in a future release.')
result = self._query(query)
9.启动 Compute 服务并将其设置为随系统启动
[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.

- 安装和配置计算节点
1.先做时间同步
[root@compute1 ~]# yum install chrony -y
[root@compute1 ~]# vim /etc/chrony.conf
server 172.25.43.250 iburst
[root@compute1 ~]# systemctl start chronyd
[root@compute1 ~]# date
2.配置新的yum源
[root@controller yum.repos.d]# scp openstack.repo compute1:/etc/yum.repos.d/
[root@compute1 ~]# yum repolist
Loaded plugins: product-id, search-disabled-repos, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
openstack | 2.9 kB 00:00:00
openstack/primary_db | 141 kB 00:00:00
repo id repo name status
openstack mitaka 279
rhel7.3 rhel7.3 4,751
repolist: 5,030
3.配置双网卡，eth1不需要ip只需要开启即可
[root@compute1 ~]# cd /etc/sysconfig/network-scripts/
[root@compute1 network-scripts]# ls
ifcfg-eth0 ifdown-isdn ifup ifup-plip ifup-tunnel
ifcfg-lo ifdown-post ifup-aliases ifup-plusb ifup-wireless
ifdown ifdown-ppp ifup-bnep ifup-post init.ipv6-global

3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 52:54:00:5c:8a:6f brd ff:ff:ff:ff:ff:ff
4.更新一下
[root@compute1 ~]# yum upgrade -y
5.安装软件包
[root@compute1 ~]# yum install openstack-nova-compute -y
6.编辑/etc/nova/nova.conf文件
[root@compute1 ~]# vim /etc/nova/nova.conf
[DEFAULT]
rpc_backend = rabbit ##配置RabbitMQ消息队列的连接：
auth_strategy = keystone ## 配置认证服务访问
my_ip = 172.25.43.2 ##配置 my_ip 选项
use_neutron = True ##使能 Networking 服务
firewall_driver = nova.virt.firewall.NoopFirewallDriver
##配置RabbitMQ消息队列的连接：
[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = openstack
##配置认证服务访问
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = nova
##启用并配置远程控制台访问
[vnc]
enabled = True
vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = $my_ip
novncproxy_base_url = http://controller:6080/vnc_auto.html
##配置镜像服务 API 的位置：
[glance]
api_servers = http://controller:9292
##配置锁路径
[oslo_concurrency]
lock_path = /var/lib/nova/tmp
7.启动计算服务及其依赖，并将其配置为随系统自动启动：
[root@compute1 ~]# systemctl enable libvirtd.service openstack-nova-compute.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-compute.service to /usr/lib/systemd/system/openstack-nova-compute.service.
[root@compute1 ~]# systemctl start libvirtd.service openstack-nova-compute.service
- 验证
1.列出服务组件，以验证是否成功启动并注册了每个进程：
[root@controller yum.repos.d]# openstack compute service list
+----+------------------+------------+----------+---------+-------+----------------------------+
| Id | Binary | Host | Zone | Status | State | Updated At |
