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 root user:
```
$ mysql -u root -p
```
- Create the manila database:
```
CREATE DATABASE manila;
```
- Grant proper access to the manila database:
```
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_DBPASS with a suitable password.
- Exit the database access client.
Source the admin credentials to gain access to admin CLI commands:
```
$ . admin-openrc.sh
```

To create the service credentials, complete these steps:

Create a manila user:

$ 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 admin role to the manila user:
```
$ openstack role add --project service --user manila admin
```
Note

This command provides no output.

Create the manila and manilav2 service 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                                    |

Note

The Shared File Systems services require endpoints for each service entity.

Install and configure components¶

Install the packages:

# yum install openstack-manila python3-manilaclient

Edit the /etc/manila/manila.conf file and complete the following actions:
- In the [database] section, configure database access:
```
[database]
...
connection = mysql+pymysql://manila:MANILA_DBPASS@controller/manila
```
  Replace MANILA_DBPASS with the password you chose for the Shared File Systems database.

Complete the rest of the configuration in manila.conf:
- In the [DEFAULT] section, configure RabbitMQ message queue access:
```
[DEFAULT]
...
transport_url = rabbit://openstack:RABBIT_PASS@controller
```
  Replace RABBIT_PASS with the password you chose for the openstack account 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_type option 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_PASS with the password you chose for the manila user in the Identity service.
- In the [DEFAULT] section, configure the my_ip option 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
