|NO.Z.00012|——————————|^^^^ 部署 ^^^^|——|OpenStack&组件.V03|——|OpenStack-nova|构建nova组件|
一、开始构建nova组件：配置先决条件
### --- 在controller节点配置：配置先决条件
### --- 创建数据库，完成下列步骤：
~~~ 使用数据库管理员root登录数据库
[root@controller ~]# mysql -uroot -p
Enter password: 123456~~~ 创建nova数据库
MariaDB [(none)]> CREATE DATABASE nova;
Query OK, 1 row affected (0.00 sec)~~~ 创建数据库用户nova，并授予nova用户对nova数据库的完全控制权限，
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost'IDENTIFIED BY'NOVA_DBPASS';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%'IDENTIFIED BY'NOVA_DBPASS';
Query OK, 0 rows affected (0.00 sec)~~~ 在compute1节点连接测试
~~~ 退出数据库连接
[root@compute ~]# yum install -y mysql
[root@compute ~]# mysql -unova -pNOVA_DBPASS -h controller.nice.com -P 3306
MariaDB [nova]> show tables;
Empty set (0.00 sec) // 空目录，还没有还原，证明权限是没有问题的。### --- 在controller节点配置：
### --- 执行admin环境脚本
[root@controller ~]# source admin-openrc.sh ### --- 在认证服务中心创建计算服务的认证信息，完成下列步骤：
~~~ 创建nova用户
[root@controller ~]# keystone user-create --name nova --pass NOVA_PASS
+----------+----------------------------------+
| Property | Value |
+----------+----------------------------------+
| email | |
| enabled | True |
| id | aec2303c9ee7480cb0696379b40eca3a |
| name | nova |
| username | nova |
+----------+----------------------------------+~~~ 链接nova用户到service租户和admin角色
~~~ --name指定类型为nova，--type：指定类型为compute，
~~~ --description描述信息为：OpenStack compute的计算节点。
[root@controller ~]# keystone user-role-add --user nova --tenant service --role admin~~~ 创建nova服务
[root@controller ~]# keystone service-create --name nova --type compute --description "OpenStack Compute"
+-------------+----------------------------------+
| Property | Value |
+-------------+----------------------------------+
| description | OpenStack Compute |
| enabled | True |
| id | e1c2ba9ab6c2423faee9b21daf57ba77 |
| name | nova |
| type | compute |
+-------------+----------------------------------+### --- 创建计算服务端点
[root@controller ~]# keystone endpoint-create \
> --service-id $(keystone service-list | awk '/ compute / {print $2}') \
> --publicurl http://controller.nice.com:8774/v2/%\(tenant_id\)s \
> --internalurl http://controller.nice.com:8774/v2/%\(tenant_id\)s \
> --adminurl http://controller.nice.com:8774/v2/%\(tenant_id\)s \
> --region regionOne
+-------------+--------------------------------------------------+
| Property | Value |
+-------------+--------------------------------------------------+
| adminurl | http://controller.nice.com:8774/v2/%(tenant_id)s |
| id | eee81988059a4695bc5a5b0789b551e1 |
| internalurl | http://controller.nice.com:8774/v2/%(tenant_id)s |
| publicurl | http://controller.nice.com:8774/v2/%(tenant_id)s |
| region | regionOne |
| service_id | e1c2ba9ab6c2423faee9b21daf57ba77 |
+-------------+--------------------------------------------------+二、安装和配置计算控制组件
### --- 在controller节点

# 编辑[DEFAULT]小节，配置VNCdialing服务的使用controller节点的管理接口ip：
[DEFAULT]
......
vncserver_listen=192.168.222.5 # 监听地址:也就是我们本机的IP地址：
vncserver_proxyclient_address=192.168.222.5 # 更改代理的地址：依然是我们本机地址
# 编辑[glance]小节，配置镜像服务器的位置
[glance]
......
host=controller.nice.com
# (可选)在[DEFAULT]小节中配置详细日志输出 ，方便排错
[DEFAULT]
