Openstack 云计算（二）： Openstack Rocky部署三 nova 部署与验证 (控制节点)

openstack系列

  • 一： nova 的部署
  • 二： nova 验证

一： nova的部署

１.１　nova　数据库创建

  1. mysql -uroot -p flyfish225
  3. CREATE DATABASE nova_api;
  4. CREATE DATABASE nova;
  5. CREATE DATABASE nova_cell0;
  6. CREATE DATABASE placement;
  8. GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';
  9. GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'nova';
  11. GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';
  12. GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'nova';
  14. GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';
  15. GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'nova';
  17. GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' IDENTIFIED BY 'placement';
  18. GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' IDENTIFIED BY 'placement';
  20. flush privileges;
  21. show databases;
  22. select user,host from mysql.user;

  1. egrep -v "^#|^$" /etc/nova/nova.conf

image_1d8n9fi8qqsoo11bg71u22bl96h.png-135.1kB

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

  1. 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）

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

  1. 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
  1. 初始化nova_cell0和nova数据库
  2. # 注册cell0数据库
  4. su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
  6. # 创建cell1单元
  8. su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
  10. # 初始化nova数据库
  12. su -s /bin/sh -c "nova-manage db sync" nova
  13. # 检查确认cell0和cell1注册成功
  15. su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova
  16. # 验证数据库
  18. mysql -h10.0.0.11 -unova -pnova -e "use nova_cell0;show tables;"
  19. mysql -h10.0.0.11 -unova -pnova -e "use nova;show tables;"

image_1d8nbkckc1aen46a18c541i1jfb8l.png-158.5kB

  1. 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 
  1. 检查确认cell0和cell1注册成功
  2. su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova

image_1d8nbmvu06841ug81r5ue6q149s92.png-76.5kB

  1. 返回的数据存储在nova_api数据库的cell_mappings表中
  1. 启动nova服务
  3. 需要启动5个服务
  5. systemctl start openstack-nova-api.service openstack-nova-consoleauth.service \
  6.   openstack-nova-scheduler.service openstack-nova-conductor.service \
  7.   openstack-nova-novncproxy.service
  9. systemctl status openstack-nova-api.service openstack-nova-consoleauth.service \
  10.   openstack-nova-scheduler.service openstack-nova-conductor.service \
  11.   openstack-nova-novncproxy.service
  13. systemctl enable openstack-nova-api.service openstack-nova-consoleauth.service \
  14.   openstack-nova-scheduler.service openstack-nova-conductor.service \
  15.   openstack-nova-novncproxy.service
  17. systemctl list-unit-files |grep openstack-nova* |grep enabled
