API, endpoint creation and database related
1. Create database and authorize
mysql -uroot -proot
Three databases need to be created: nova_api，nova，nova_cell0, set the password to 111111
CREATE DATABASE nova_api; CREATE DATABASE nova; CREATE DATABASE nova_cell0; GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY '111111'; GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY '111111'; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY '111111'; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY '111111'; GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY '111111'; GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY '111111'; flush privileges; show databases; select user,host from mysql.user; exit
2. Create computing service credentials
(1) Create nova user on keystone
First load the environment variable source / Admin openrc sh
cd source admin-openrc.sh
openstack user create --domain default --password=111111 nova openstack user list
(2) Configure the nova user as the admin role on keystone and add it to the service project
openstack role add --project service --user nova admin
(3) Create entity of nova computing service
openstack service create --name nova --description "OpenStack Compute" compute openstack service list
3. Create compute API service 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 openstack endpoint list
nova related software installation and configuration
1. Install nova related software
yum install openstack-nova-api openstack-nova-conductor openstack-nova-novncproxy openstack-nova-scheduler -y
2. Modification of configuration file
Edit VIM / etc / Nova / nova Conf file, nearly 6000 lines
cp /etc/nova/nova.conf /etc/nova/nova.conf.bak egrep -v "^$|^#" /etc/nova/nova.conf.bak >/etc/nova/nova.conf
The command line modifies the configuration information. The command should not be operated in batches at one time. Because there are too many commands, the batch execution terminal may make errors. It is recommended to execute in batches

echo "Result of Configuration" egrep -v "^#|^$" /etc/nova/nova.conf
3. Create and synchronize databases
(1) Synchronize Nova API database
su -s /bin/sh -c "nova-manage api_db sync" nova mysql -unova -pnova -e "use nova_api;show tables;" mysql -unova -p111111 -e "use nova_api;show tables;"
(2) Synchronize cell0 database
su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
(3) Create cell1 cell
su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
(4) Initialize and synchronize nova database
su -s /bin/sh -c "nova-manage db sync" nova
(5) Verify Nova_ Are cell0 and cell1 added successfully
su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova
(6) Validate database
mysql -unova -p111111 -e "use nova_api;show tables;" mysql -uplacement -p111111 -e "use placement;show tables;"
4. Start the computing server and set the startup self startup
systemctl start openstack-nova-api openstack-nova-scheduler openstack-nova-conductor openstack-nova-novncproxy systemctl enable openstack-nova-api openstack-nova-scheduler openstack-nova-conductor openstack-nova-novncproxy
5. Verify whether the service is started successfully
Use command
source admin-openrc.sh nova service-list netstat -lntup | grep 6080 systemctl list-unit-files |grep openstack-nova* |grep enabled
Four services have been started. Why do you only see two services?
This is because the Nova service list command is sent to openstack Nova API, and the openstack Nova API service returns the response result. If the Nova API service is closed, the openstack Nova scheduler and openstack Nova conductor services cannot be started, while the openstack Nova novncproxy service is started successfully, which is viewed through the port. netstat -lntup | grep 6080, View the process number obtained from the last command of process ps -ef | grep.
The noVNC page can be accessed through the Web, but the virtual machine is not connected yet
Control node Nova service installation completed
So far, the installation of computing service nova in the control node is completed. The next article introduces the installation method of Nova service in the independent computing node.
If you use VMware virtual machine, you can now shut down and take a snapshot.
