Install and configure controller node on Red Hat Enterprise Linux and CentOS¶
This section describes how to install and configure the Shared File Systems service, code-named manila, on the controller node that runs Red Hat Enterprise Linux or CentOS. This service requires at least one additional share node that manages file storage back ends.
Prerequisites¶
Before you install and configure the Shared File Systems service, you must create a database, service credentials, and API endpoints.
- To create the database, complete these steps: - Use the database access client to connect to the database server as the - rootuser:- $ mysql -u root -p 
- Create the manila database: - CREATE DATABASE manila;
- Grant proper access to the - maniladatabase:- GRANT ALL PRIVILEGES ON manila.* TO 'manila'@'localhost' \ IDENTIFIED BY 'MANILA_DBPASS'; GRANT ALL PRIVILEGES ON manila.* TO 'manila'@'%' \ IDENTIFIED BY 'MANILA_DBPASS'; - Replace - MANILA_DBPASSwith a suitable password.
- Exit the database access client. 
 
- Source the - admincredentials to gain access to admin CLI commands:- $ . admin-openrc.sh 
- To create the service credentials, complete these steps: - Create a - manilauser:- $ openstack user create --domain default --password-prompt manila User Password: Repeat User Password: +---------------------+----------------------------------+ | Field | Value | +---------------------+----------------------------------+ | domain_id | e0353a670a9e496da891347c589539e9 | | enabled | True | | id | 83a3990fc2144100ba0e2e23886d8acc | | name | manila | | options | {} | | password_expires_at | None | +---------------------+----------------------------------+ 
- Add the - adminrole to the- manilauser:- $ openstack role add --project service --user manila admin - Note - This command provides no output. 
- Create the - manilaand- manilav2service entities:- $ openstack service create --name manila \ --description "OpenStack Shared File Systems" share +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | OpenStack Shared File Systems | | enabled | True | | id | 82378b5a16b340aa9cc790cdd46a03ba | | name | manila | | type | share | +-------------+----------------------------------+ - $ openstack service create --name manilav2 \ --description "OpenStack Shared File Systems V2" sharev2 +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | OpenStack Shared File Systems V2 | | enabled | True | | id | 30d92a97a81a4e5d8fd97a32bafd7b88 | | name | manilav2 | | type | sharev2 | +-------------+----------------------------------+ - Note - The Shared File Systems services require two service entities. 
 
- Create the Shared File Systems service API endpoints: - $ openstack endpoint create --region RegionOne \ share public http://controller:8786/v1/%\(tenant_id\)s +--------------+------------------------------------------+ | Field | Value | +--------------+------------------------------------------+ | enabled | True | | id | 0bd2bbf8d28b433aaea56a254c69f69d | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | 82378b5a16b340aa9cc790cdd46a03ba | | service_name | manila | | service_type | share | | url | http://controller:8786/v1/%(project_id)s | +--------------+------------------------------------------+ $ openstack endpoint create --region RegionOne \ share internal http://controller:8786/v1/%\(tenant_id\)s +--------------+------------------------------------------+ | Field | Value | +--------------+------------------------------------------+ | enabled | True | | id | a2859b5732cc48b5b083dd36dafb6fd9 | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | 82378b5a16b340aa9cc790cdd46a03ba | | service_name | manila | | service_type | share | | url | http://controller:8786/v1/%(project_id)s | +--------------+------------------------------------------+ $ openstack endpoint create --region RegionOne \ share admin http://controller:8786/v1/%\(tenant_id\)s +--------------+------------------------------------------+ | Field | Value | +--------------+------------------------------------------+ | enabled | True | | id | f7f46df93a374cc49c0121bef41da03c | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | 82378b5a16b340aa9cc790cdd46a03ba | | service_name | manila | | service_type | share | | url | http://controller:8786/v1/%(project_id)s | +--------------+------------------------------------------+ - $ openstack endpoint create --region RegionOne \ sharev2 public http://controller:8786/v2 +--------------+-----------------------------------------+ | Field | Value | +--------------+-----------------------------------------+ | enabled | True | | id | d63cc0d358da4ea680178657291eddc1 | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | 30d92a97a81a4e5d8fd97a32bafd7b88 | | service_name | manilav2 | | service_type | sharev2 | | url | http://controller:8786/v2 | +--------------+-----------------------------------------+ $ openstack endpoint create --region RegionOne \ sharev2 internal http://controller:8786/v2 +--------------+-----------------------------------------+ | Field | Value | +--------------+-----------------------------------------+ | enabled | True | | id | afc86e5f50804008add349dba605da54 | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | 30d92a97a81a4e5d8fd97a32bafd7b88 | | service_name | manilav2 | | service_type | sharev2 | | url | http://controller:8786/v2 | +--------------+-----------------------------------------+ $ openstack endpoint create --region RegionOne \ sharev2 admin http://controller:8786/v2 +--------------+-----------------------------------------+ | Field | Value | +--------------+-----------------------------------------+ | enabled | True | | id | e814a0cec40546e98cf0c25a82498483 | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | 30d92a97a81a4e5d8fd97a32bafd7b88 | | service_name | manilav2 | | service_type | sharev2 | | url | http://controller:8786/v2 | +--------------+-----------------------------------------+ - Note - The Shared File Systems services require endpoints for each service entity. 
Install and configure components¶
- Install the packages: - # dnf install openstack-manila python3-manilaclient 
- Edit the - /etc/manila/manila.conffile and complete the following actions:- In the - [database]section, configure database access:- [database] ... connection = mysql+pymysql://manila:MANILA_DBPASS@controller/manila - Replace - MANILA_DBPASSwith the password you chose for the Shared File Systems database.
 
- Complete the rest of the configuration in - manila.conf:- In the - [DEFAULT]section, configure- RabbitMQmessage queue access:- [DEFAULT] ... transport_url = rabbit://openstack:RABBIT_PASS@controller - Replace - RABBIT_PASSwith the password you chose for the- openstackaccount in- RabbitMQ.
- In the - [DEFAULT]section, set the following config values:- [DEFAULT] ... default_share_type = default_share_type share_name_template = share-%s rootwrap_config = /etc/manila/rootwrap.conf api_paste_config = /etc/manila/api-paste.ini - Important - The - default_share_typeoption specifies the default share type to be used when shares are created without specifying the share type in the request. The default share type that is specified in the configuration file has to be created with the necessary required extra-specs (such as- driver_handles_share_servers) set appropriately with reference to the driver mode used. This is further explained in the section discussing the setup and configuration of the share node.
- In the - [DEFAULT]and- [keystone_authtoken]sections, configure Identity service access:- [DEFAULT] ... auth_strategy = keystone [keystone_authtoken] ... memcached_servers = controller:11211 www_authenticate_uri = http://controller:5000 auth_url = http://controller:5000 auth_type = password project_domain_name = Default user_domain_name = Default project_name = service username = manila password = MANILA_PASS - Replace - MANILA_PASSwith the password you chose for the- manilauser in the Identity service.
- In the - [DEFAULT]section, configure the- my_ipoption to use the management interface IP address of the controller node:- [DEFAULT] ... my_ip = 10.0.0.11 
- In the - [oslo_concurrency]section, configure the lock path:- [oslo_concurrency] ... lock_path = /var/lock/manila 
 
- Populate the Shared File Systems database: - # su -s /bin/sh -c "manila-manage db sync" manila - Note - Ignore any deprecation messages in this output. 
Finalize installation¶
- Start the Shared File Systems services and configure them to start when the system boots: - # systemctl enable openstack-manila-api.service openstack-manila-scheduler.service # systemctl start openstack-manila-api.service openstack-manila-scheduler.service
