OpenStack is composed of four parts: control node, compute node, network node and storage node. The previous blog post detailed the horizon component in the control node service controller, and this blog post will detail the deployment of the storage node cinder. Divided into two parts: control node and storage node

OpenStack Storage Node Architecture

Storage nodes include services such as Cinder and Swift.

Cinder： Block storage service provides corresponding block storage. In simple terms, it is a virtual disk that can be mounted on the corresponding virtual machine without being affected by factors such as file system. For virtual machines, this operation is like adding a new hard disk, which can complete any operation on the disk, including mounting, unmounting, formatting, converting file system, etc. Swift: Object storage service provides corresponding object storage. Simply put, it is to create a virtual disk space in which files can be stored, only files can be stored, and formatting cannot be performed. File system conversion is mostly applied to cloud disks/files.

Storage nodes contain a minimum of two network interfaces

eth0: Communicate with control node, accept control node tasks, and be uniformly deployed by control node

eth2： Communicate with computing/network nodes and complete various tasks issued by control nodes. The host system IP address is angle-color controller CentOS7192.168.37.128keystone, nova, glare, neutron, horizon, cinder, ntp, mariadb, rabbitmq, memcached, etcd, apachecomputeCentOS7192.168.37.130nova, neutron, ntpcinderCentOS7192.168.37.131cinder, ntp Experimental process

++ Install and configure Cinder nodes ++

1. Add or create a disk sdb

fdisk /dev/sdb

2. Create LVM physical logical volume/dev/sdb1

pvcreate /dev/sdb1

3. Create a cinder-volumes logical volume group

vgcreate cinder-volumes /dev/sdb1

4, yum install the Cinder software package

yum install openstack-cinder targetcli python-keystone -y

5. Edit configuration files

vim /etc/cinder/cinder.conf

[DEFAULT]#1302transport_url = rabbit://openstack:123456@controller#399auth_strategy = keystone#291my_ip = 192.168.175.155#403enabled_backends = lvm #Supported format #296glance_api_servers = http://controller:9292[database]#3586connection = mysql+pymysql://cinder:123456@controller/cinder[keystone_authtoken]#3850auth_uri = http://www.mymysql.com//controller:5000auth_url = http://controller:35357#3901memcached_servers = controller:11211#4008auth_type = passwordproject_domain_id = defaultuser_domain_id = defaultproject_name = serviceusername = cinderpassword = 1 23456 [oslo_concurrency]#4125lock_path = /var/lib/cinder/tmp#Add the [lvm] module at the end to configure the LVM backend using the LVM driver, cinder-volumes volume groups, iSCSI protocol and corresponding iSCSI services. [lvm] volume_driver = cinder.volume.drivers.lvm.LVMVolumeDrivervolume_group = cinder-volumesiscsi_protocol = iscsiiscsi_helper = lioadm

6. Turn on the Cinder service and set it to boot automatically.

systemctl enable openstack-cinder-volume.service target.service

systemctl start openstack-cinder-volume.service target.service

++ Install and configure controller nodes ++

1. Configuration database

mysql -u root -p

create database cinder;

grant all privileges on cinder. to 'cinder'@'localhost' identified by '123456';

grant all privileges on cinder. to 'cinder'@'%' identified by '123456';

2. Create a user finder

source ~/admin-openrc

openstack user create --domain default --password-prompt cinder

Password: 123456

3. Add roles

openstack role add --project service --user cinder admin

4. Create cinderv2 and cinderv3 service entities

openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2

openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3

5. Create a Block Storage Service API

openstack endpoint create --region RegionOne volumev2 public http://controller:8776/v2/%\(project_id\)sopenstack endpoint create --region RegionOne volumev2 internal http://controller:8776/v2/%\(project_id\)sopenstack endpoint create --region RegionOne volumev2 admin http://controller:8776/v2/%\(project_id\)sopenstack endpoint create --region RegionOne volumev3 public http://controller:8776/v3/%\(project_id\)sopenstack endpoint create --region RegionOne volumev3 internal http://controller:8776/v3/%\(project_id\)sopenstack endpoint create --region RegionOne volumev3 admin http://controller:8776/v3/%\(project_id\)s

6. Install the Cinder software package

yum install openstack-cinder -y

7. Edit configuration files

vim /etc/cinder/cinder.conf

[database]#3586connection = mysql+pymysql://cinder:123456@controller/cinder[DEFAULT]#1302transport_url = rabbit://openstack:123456@controller#399auth_strategy = keystone#291my_ip = 192.168.175.145[keystone_authtoken]#3850auth_uri = http://controller:5000auth_url = http://controller:35357#3901memcached_servers = controller:11211#4008auth_type = passwordproject_domain_id = defaultuser_domain_id = defaultproject_name = serviceusername = cinderpassword = 123456[oslo_concurrency]#4126lock_path = /var/lib/cinder/tmp

8. Synchronous database

su -s /bin/sh -c "cinder-manage db sync" cinder

9. Edit nova profile

vim /etc/nova/nova.conf

[cinder]#4237os_region_name = RegionOne

10. Restart the openstack-nova-api service and start the finder service.

systemctl restart openstack-nova-api.service

systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service

systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service

11. View User Cinder

12. View service entity

So far, the cinder component part has been deployed completely, thank you for reading!
