6. Configure Compute services

Controller Node:

1. sudo apt-get install nova-api nova-cert nova-conductor nova-consoleauth nova-novncproxy nova-scheduler python-novaclient

 

2. sudo vi /etc/nova/nova.conf

[database]

connection = mysql://nova:NOVA_DBPASS@controller/nova

[DEFAULT]

...

rpc_backend = rabbit

rabbit_host = controller

rabbit_password = RABBIT_PASS

[DEFAULT]

...

my_ip = 10.0.0.11 (controller_node_ip)

vncserver_listen = 10.0.0.11 (controller_node_ip)

vncserver_proxyclient_address = 10.0.0.11 (controller_node_ip)

 

3. sudo rm /var/lib/nova/nova.sqlite

 

4. 创建数据库

mysql -u root -p

CREATE DATABASE nova;

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';

 

5. sudo -s /bin/sh -c "nova-manage db sync" nova

 

6. 创建用户

keystone user-create --name=nova --pass=NOVA_PASS --email=nova@example.com

keystone user-role-add --user=nova --tenant=service --role=admin

 

7. sudo vi /etc/nova/nova.conf

[DEFAULT]

...

auth_strategy = keystone

[keystone_authtoken]

...

auth_uri = http://controller:5000

auth_host = controller

auth_port = 35357

auth_protocol = http

admin_tenant_name = service

admin_user = nova

admin_password = NOVA_PASS

 

8. 

keystone service-create --name=nova --type=compute --description="OpenStack Compute" 

keystone endpoint-create \

  --service-id=$(keystone service-list | awk '/ compute / {print $2}') \

  --publicurl=http://controller:8774/v2/%\(tenant_id\)s \

  --internalurl=http://controller:8774/v2/%\(tenant_id\)s \

  --adminurl=http://controller:8774/v2/%\(tenant_id\)s

 

9. 重启服务

sudo service nova-api restart

sudo service nova-cert restart

sudo service nova-consoleauth restart

sudo service nova-scheduler restart

sudo service nova-conductor restart

sudo service nova-novncproxy restart

 

10. nova image-list

 

Compute Node:

1. sudo apt-get install nova-compute-kvm

 

2. sudo vi /etc/nova/nova.conf

[DEFAULT]

...

auth_strategy = keystone

...

rpc_backend = rabbit

rabbit_host = controller

rabbit_password = RABBIT_PASS

...

my_ip = 10.0.0.31 (Compute Node IP)

vnc_enabled = True

vncserver_listen = 0.0.0.0

vncserver_proxyclient_address = 10.0.0.31  (Compute Node IP)

novncproxy_base_url = http://controller:6080/vnc_auto.html

...

glance_host = controller

 

[database]

# The SQLAlchemy connection string used to connect to the database

connection = mysql://nova:NOVA_DBPASS@controller/nova

 

[keystone_authtoken]

auth_uri = http://controller:5000

auth_host = controller

auth_port = 35357

auth_protocol = http

admin_tenant_name = service

admin_user = nova

admin_password = NOVA_PASS

 

3. 检测服务器是否支持虚拟化

egrep -c '(vmx|svm)' /proc/cpuinfo

若结果不为零,则继续进行下一步;若为零,需将/etc/nova/nova-compute.conf里的virt_type置为qemu

 

4. sudo rm /var/lib/nova/nova.sqlite

 

5. sudo service nova-compute restart
