6. Install Nova service [VMware virtual machine to build Openstack + Ironic]
Basic instructions
To provide computing services, it needs to be installed on the control node and computing node.
controller node
Database operations
1. Enter the database
mysql -uroot -p123456
2. Create nova database
CREATE DATABASE nova_api default character set utf8; CREATE DATABASE nova default character set utf8; CREATE DATABASE nova_cell0 default character set utf8;
3. Create user and authorize
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY '123456'; GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY '123456'; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY '123456'; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY '123456'; GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY '123456'; GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY '123456';
Create users and configure endpoints
1. Activate environment variables
source /root/source-admin.sh
2. Create user
openstack user create --domain default --password 123456 nova
3. Create roles and authorize
openstack role add --project service --user nova admin
4. Create services
openstack service create --name nova --description "OpenStack Compute" compute
5. Create endpoint
openstack endpoint create --region RegionOne compute public http://controller:8774/v2.1 openstack endpoint create --region RegionOne compute internal http://controller:8774/v2.1 openstack endpoint create --region RegionOne compute admin http://controller:8774/v2.1
Install and configure nova components
1. Install software
yum -y install openstack-nova-api openstack-nova-conductor openstack-nova-novncproxy openstack-nova-scheduler
2. Modify configuration file
cd /etc/nova/ & amp; & amp; mv nova.conf nova.conf.source & amp; & amp; cat nova.conf.source |grep -Ev "^#|^$" > nova. conf & amp; & amp; chown root:nova nova.conf
vim /etc/nova/nova.conf

3. Synchronize nova-api database
su -s /bin/sh -c "nova-manage api_db sync" nova
4. Synchronize cell0 database
su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
5. Create cell1
su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
6. Synchronize nova database
su -s /bin/sh -c "nova-manage db sync" nova
7. Verify whether cell0 and cell1 are registered correctly
su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova
8. Start the service and set it to start automatically at boot
systemctl enable openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service systemctl restart openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service systemctl status openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
compute node
Install and configure nova components
1. Install software
yum -y install openstack-nova-compute
2. Modify configuration file
cd /etc/nova/ & amp; & amp; mv nova.conf nova.conf.source & amp; & amp; cat nova.conf.source |grep -Ev "^#|^$" > nova. conf & amp; & amp; chown nova:root nova.conf
vim /etc/nova/nova.conf

3. Start and restart the service
systemctl enable libvirtd.service openstack-nova-compute.service systemctl restart libvirtd.service openstack-nova-compute.service systemctl status libvirtd.service openstack-nova-compute.service
4. Add computing nodes to the database on the controller node
–control node operation–
openstack compute service list --service nova-compute
su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
Verification
