OpenStack Yoga版安装笔记（十二）nova安装（下）

5、Install and configure controller node for Ubuntu

注意安装版本为：nova 25.2.2.dev5

5.1 Prerequisites

在安装和配置compute service之前，需要先创建数据库、服务凭证（用户名/密码）、服务API端点。

1、Create the database：

  1. root@controller:~# mysql
  2. Welcome to the MariaDB monitor.  Commands end with ; or \g.
  3. Your MariaDB connection id is 31
  4. Server version: 10.6.18-MariaDB-0ubuntu0.22.04.1 Ubuntu 22.04
  5.  
  6. Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
  7.  
  8. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
  9.  
  10. MariaDB [(none)]> CREATE DATABASE nova_api;
  11. Query OK, 1 row affected (0.001 sec)
  12.  
  13. MariaDB [(none)]> CREATE DATABASE nova;
  14. Query OK, 1 row affected (0.000 sec)
  15.  
  16. MariaDB [(none)]> CREATE DATABASE nova_cell0;
  17. Query OK, 1 row affected (0.000 sec)
  18.  
  19. MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \
  20.     ->   IDENTIFIED BY 'openstack';
  21. Query OK, 0 rows affected (0.002 sec)
  22.  
  23. MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' \
  24.     ->   IDENTIFIED BY 'openstack';
  25. Query OK, 0 rows affected (0.001 sec)
  26.  
  27. MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \
  28.     ->   IDENTIFIED BY 'openstack';
  29. Query OK, 0 rows affected (0.001 sec)
  30.  
  31. MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \
  32.     ->   IDENTIFIED BY 'openstack';
  33. Query OK, 0 rows affected (0.001 sec)
  34.  
  35. MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' \
  36.     ->   IDENTIFIED BY 'openstack';
  37. Query OK, 0 rows affected (0.001 sec)
  38.  
  39. MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' \
  40.     ->   IDENTIFIED BY 'openstack';
  41. Query OK, 0 rows affected (0.001 sec)
  42.  
  43. MariaDB [(none)]> quit
  44. Bye
  45. root@controller:~#

 2、Configure User and Endpoints

  1. root@controller:~# . admin-openrc 
  2. root@controller ~(admin/amdin)# openstack user create --domain default --password-prompt nova
  3. User Password:
  4. Repeat User Password:

2、Edit the /etc/nova/nova.conf file

  1. root@controller:~# vi /etc/nova/nova.conf
  2.  
  3. [api_database]
  4. # connection = sqlite:var/lib/nova/nova_api.sqlite
  5. connection = mysql+pymysql://nova:openstack@controller/nova_api

4、Register the cell0 database:

  1. root@controller:~# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
  2. Modules with known eventlet monkey patching issues were imported prior to eventlet monkey patching: urllib3. This warning can usually be ignored if the caller is only importing and not executing nova code.
  3. root@controller:~#

5、Create the cell1 cell:

  1. root@controller:~# su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
  2. Modules with known eventlet monkey patching issues were imported prior to eventlet monkey patching: urllib3. This warning can usually be ignored if the caller is only importing and not executing nova code.
  3. --transport-url not provided in the command line, using the value [DEFAULT]/transport_url from the configuration file
  4. --database_connection not provided in the command line, using the value [database]/connection from the configuration file
  5. 8b1967df-7901-42b3-8b03-fc4e884f490d
  6. root@controller:~#

6、Populate the nova database:

  1. root@controller:~# su -s /bin/sh -c "nova-manage db sync" nova
  2. Modules with known eventlet monkey patching issues were imported prior to eventlet monkey patching: urllib3. This warning can usually be ignored if the caller is only importing and not executing nova code.

  11. root@controller:~#

7、Verify nova cell0 and cell1 are registered correctly:

  1. root@controller:~# su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova
  2. Modules with known eventlet monkey patching issues were imported prior to eventlet monkey patching: urllib3. This warning can usually be ignored if the caller is only importing and not executing nova code.

6、Install and configure a compute node for Ubuntu

计算服务（Compute Service）支持多种hypervisor来部署实例或虚拟机。为了简化配置，这里使用Quick EMUlator（QEMU）hypervisor，并在支持虚拟机硬件加速的计算节点上结合了基于内核的虚拟机（KVM）扩展。在不支持硬件加速的传统硬件上，可以使用通用的QEMU hypervisor。另外可以通过简单修改这里的配置，增加额外的计算节点，从而水平扩展计算环境。

6.1 Install and configure components

root@compute1:~# apt install nova-compute

 6.2 Edit the /etc/nova/nova.conf file

  1. root@compute1:~# vi /etc/nova/nova.conf

6.3 Finalize installation

1、检查计算节点（compute node)是否支持硬件虚拟化，返回1或者大于1，则支持；返回0则不支持：

  1. root@compute1:~# egrep -c '(vmx|svm)' /proc/cpuinfo
  2. 8

2、重启compute service：

  1. root@compute1:~# service nova-compute restart
  2.  
  3. root@compute1:~# systemctl status nova-compute

6.4 Add the compute node to the cell database

1、以admin的凭证获取admin-only openstack CLI，查看数据库是否有compute host：

  1. root@controller ~(admin/amdin)# cat admin-openrc 
  2. export OS_PROJECT_DOMAIN_NAME=Default
  3. export OS_USER_DOMAIN_NAME=Default
  4. export OS_PROJECT_NAME=admin
  5. export OS_USERNAME=admin
  6. export OS_PASSWORD=openstack
  7. export OS_AUTH_URL=http://controller:5000/v3
  8. export OS_IDENTITY_API_VERSION=3
