B09-openstack高可用(t版)-nova控制节点集群部署

1. 创建nova相关数据库

[root@controller01 ~]# mysql -u root -phuayun -e "CREATE DATABASE nova_api;"
[root@controller01 ~]# mysql -u root -phuayun -e "CREATE DATABASE nova;"
[root@controller01 ~]# mysql -u root -phuayun -e "CREATE DATABASE nova_cell0;"

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost'
-> IDENTIFIED BY 'huayun';

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%'
-> IDENTIFIED BY 'huayun';

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost'
-> IDENTIFIED BY 'huayun';

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%'
-> IDENTIFIED BY 'huayun';

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost'
-> IDENTIFIED BY 'huayun';

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%'
-> IDENTIFIED BY 'huayun';

2. 创建nova

1）创建nova

[root@controller01 ~]# openstack user create --domain default --password=huayun nova

2）为nova用户赋予admin权限

[root@controller01 ~]# openstack role add --project service --user nova admin

3）创建nova服务实体

[root@controller01 ~]# openstack service create --name nova   --description "OpenStack Compute" compute

4）创建/placement-api

# 注意--region与初始化admin用户时生成的region一致；
# api地址统一采用vip，如果public/internal/admin分别使用不同的vip，请注意区分；
# nova-api 服务类型为compute，placement-api服务类型为placement；
# nova public api

创建nova的api

[root@controller01 ~]# openstack endpoint create --region RegionOne   compute public http://10.100.214.200:8774/v2.1

[root@controller01 ~]#  openstack endpoint create --region RegionOne  compute internal http://10.100.214.200:8774/v2.1

[root@controller01 ~]#  openstack endpoint create --region RegionOne  compute admin http://10.100.214.200:8774/v2.1

 

 

3. 安装nova

[root@controller01 ~]# yum install openstack-nova-api openstack-nova-conductor   openstack-nova-novncproxy openstack-nova-scheduler -y

4. 配置nova.conf

[root@controller01 ~]# egrep -v "^#|^$" /etc/nova/nova.conf
[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:huayun@10.100.214.201:5672,10.100.214.202:5672,10.100.214.203:5672
my_ip = 10.100.214.201
use_neutron = true
firewall_driver = nova.virt.firewall.NoopFirewallDriver
osapi_compute_listen_port=8774

将nova的配置文件拷贝到另外的控制节点上：

[root@controller01 ~]# scp /etc/nova/nova.conf 10.100.214.202:/etc/nova/
[root@controller01 ~]# scp /etc/nova/nova.conf 10.100.214.203:/etc/nova/

6. 同步nova相关数据库

# 任意控制节点操作；
# 同步nova-api数据库
[root@controller01 ~]# su -s /bin/sh -c "nova-manage api_db sync" nova

# 注册cell0数据库
[root@controller01 ~]# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova

# 创建cell1 cell
[root@controller01 ~]# su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova

# 同步nova数据库；
# 忽略”deprecated”信息
[root@controller01 ~]# su -s /bin/sh -c "nova-manage db sync" nova

[root@controller01 ~]# su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova
+-------+--------------------------------------+---------------------------------------------+-----------------------------------------------------+----------+
| Name | UUID | Transport URL | Database Connection | Disabled |
+-------+--------------------------------------+---------------------------------------------+-----------------------------------------------------+----------+
| cell0 | 00000000-0000-0000-0000-000000000000 | none:/ | mysql+pymysql://nova:****@10.100.214.200/nova_cell0 | False |
| cell1 | 73beb316-80db-447d-bbfe-e968b8c2c880 | rabbit://openstack:****@10.100.214.200:5672 | mysql+pymysql://nova:****@10.100.214.200/nova | False |
+-------+--------------------------------------+---------------------------------------------+-----------------------------------------------------+----------+

7. 启动服务

[root@controller01 ~]# systemctl enable     openstack-nova-api.service     openstack-nova-scheduler.service     openstack-nova-conductor.service     openstack-nova-novncproxy.service

[root@controller02 ~]#  systemctl  start     openstack-nova-api.service     openstack-nova-scheduler.service     openstack-nova-conductor.service     openstack-nova-novncproxy.service

8. 验证

[root@controller01 ~]# netstat -tunlp | egrep '8774|8775|8778|6080'

 [root@controller01 ~]# openstack compute service list

 [root@controller01 ~]# openstack catalog list

 检查cell与placement api运行正常

[root@controller01 ~]# nova-status upgrade check

检测的时候会发现下面的报错，这个是t版本的一个bug

只需要在执行下面操作：（在该文件最下面添加即可）

[root@controller01 ~]# vim /etc/httpd/conf.d/00-placement-api.conf

<Directory /usr/bin>
<IfVersion >= 2.4>
Require all granted
</IfVersion>
<IfVersion < 2.4>
Order allow,deny
Allow from all
</IfVersion>
</Directory>

重启httpd服务：

systemctl restart httpd

9. 设置pcs资源

[root@controller01 ~]# pcs resource create openstack-nova-api systemd:openstack-nova-api --clone interleave=true
[root@controller01 ~]# pcs resource create openstack-nova-scheduler systemd:openstack-nova-scheduler --clone interleave=true
[root@controller01 ~]# pcs resource create openstack-nova-conductor systemd:openstack-nova-conductor --clone interleave=true
[root@controller01 ~]# pcs resource create openstack-nova-novncproxy systemd:openstack-nova-novncproxy --clone interleave=true

查看pcs资源
