## 一： nova的部署 ##

\#\#\#１.１　nova　数据库创建

mysql -uroot -p flyfish225
    
    CREATE DATABASE nova_api;
    CREATE DATABASE nova;
    CREATE DATABASE nova_cell0;
    CREATE DATABASE placement;
    
    GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';
    GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'nova';
    
    GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';
    GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'nova';
    
    GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';
    GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'nova';

    GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' IDENTIFIED BY 'placement';
    
    flush privileges;
    show databases;
    select user,host from mysql.user;

### 1.2 在keystone上面注册nova服务 ###

openstack user create --domain default --password=nova nova
    openstack user list

![image\_1d8n8a7r3d5c4rc1rn5141a1thi1g.png-110.4kB][image_1d8n8a7r3d5c4rc1rn5141a1thi1g.png-110.4kB]

在keystone上将nova用户配置为admin角色并添加进service项目
    openstack role add --project service --user nova admin

![image\_1d8n8c05pl1d1kku4bq62uc9j2g.png-23.3kB][image_1d8n8c05pl1d1kku4bq62uc9j2g.png-23.3kB]

创建nova计算服务的实体
    
    openstack service create --name nova --description "OpenStack Compute" compute
    openstack service list

![4.png-69.1kB][]

创建计算服务的API端点（endpoint）
    
    openstack endpoint create --region RegionOne compute public http://controller:8774/v2.1
    openstack endpoint create --region RegionOne compute internal http://controller:8774/v2.1
    openstack endpoint create --region RegionOne compute admin http://controller:8774/v2.1
    
    openstack endpoint list

![image\_1d8n8j7891f1e14ao1vg27q61mfm39.png-143.2kB][image_1d8n8j7891f1e14ao1vg27q61mfm39.png-143.2kB]

![image\_1d8n8k4su59dv5qudv1b311vsp3m.png-219.1kB][image_1d8n8k4su59dv5qudv1b311vsp3m.png-219.1kB]

这个版本的nova增加了placement项目
    
    同样，创建并注册该项目的服务证书
    
    openstack user create --domain default --password=placement placement
    openstack role add --project service --user placement admin
    openstack service create --name placement --description "Placement API" placement

![5.png-73.2kB][]

创建placement项目的endpoint（API端口）
    
    openstack endpoint create --region RegionOne placement public http://controller:8778
    openstack endpoint create --region RegionOne placement internal http://controller:8778
    openstack endpoint create --region RegionOne placement admin http://controller:8778
    openstack endpoint list

在控制节点安装nova相关服务 
    
    yum install openstack-nova-api openstack-nova-conductor \

修改nova的虚拟主机配置文件
    cp /etc/httpd/conf.d/00-nova-placement-api.conf /etc/httpd/conf.d/00-nova-placement-api.conf.bak
    
    vim /etc/httpd/conf.d/00-nova-placement-api.conf

至此，nova计算服务的软件包安装完成

--------------------

### 1.3 同步nova数据（注意同步顺序） ###

nova_api有32张表，placement有32张表，nova_cell0有110张表，nova也有110张表
    
     初始化nova-api和placement数据库
    
     su -s /bin/sh -c "nova-manage api_db sync" nova
    
     mysql -h10.0.0.11 -unova -pnova -e "use nova_api;show tables;"
    mysql -h10.0.0.11 -uplacement -pplacement -e "use placement;show tables;"

![image\_1d8n9unucsooc7v1ppr1ka1dfp7b.png-146.5kB][image_1d8n9unucsooc7v1ppr1ka1dfp7b.png-146.5kB]

![image\_1d8n9vdg3rc11gnn1d5f1ua217jv7r.png-128.6kB][image_1d8n9vdg3rc11gnn1d5f1ua217jv7r.png-128.6kB]

nova_api和placement都有32张表，区别在于nova_api数据库的cell_mappings表多两条数据，存放的是nova和rabbitmq等的配置信息

初始化nova_cell0和nova数据库
    # 注册cell0数据库
    
    su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
    
    # 创建cell1单元
    
    su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
    
    # 初始化nova数据库
    
    su -s /bin/sh -c "nova-manage db sync" nova
    # 检查确认cell0和cell1注册成功
    
    su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova
    # 验证数据库
    
    mysql -h10.0.0.11 -unova -pnova -e "use nova_cell0;show tables;"
    mysql -h10.0.0.11 -unova -pnova -e "use nova;show tables;"

![image\_1d8nbj687rqer07st01kn518l388.png-232.9kB][image_1d8nbj687rqer07st01kn518l388.png-232.9kB]

![image\_1d8nbkckc1aen46a18c541i1jfb8l.png-158.5kB][image_1d8nbkckc1aen46a18c541i1jfb8l.png-158.5kB]

通过对比可知，这两个数据库的表目前完全一样，区别在于nova数据库的service表中有4条数据，存放的是当前版本nova相关服务的注册信息

--------------------

检查确认cell0和cell1注册成功
    su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova

![image\_1d8nbmvu06841ug81r5ue6q149s92.png-76.5kB][image_1d8nbmvu06841ug81r5ue6q149s92.png-76.5kB]

返回的数据存储在nova_api数据库的cell_mappings表中

启动nova服务
    
    需要启动5个服务
    
    systemctl start openstack-nova-api.service openstack-nova-consoleauth.service \
      openstack-nova-scheduler.service openstack-nova-conductor.service \
      openstack-nova-novncproxy.service
    
    systemctl status openstack-nova-api.service openstack-nova-consoleauth.service \
      openstack-nova-scheduler.service openstack-nova-conductor.service \
      openstack-nova-novncproxy.service
    
    systemctl enable openstack-nova-api.service openstack-nova-consoleauth.service \
      openstack-nova-scheduler.service openstack-nova-conductor.service \
      openstack-nova-novncproxy.service
    
    systemctl list-unit-files |grep openstack-nova* |grep enabled

至此，在控制节点安装nova计算服务就完成了，下篇文章介绍独立的nova计算节点的安装方法
