OpenStack  File Share Service(Manila) For Centos

Introduction:

Manila is the File Shareservice project for OpenStack. To administer the OpenStack File Share service,it is helpful to understand a number of concepts like share networks, shares,multi-tenancy and back ends that can be configured with Manila. Whenconfiguring the File Share service, it is required to declare at least one backend. Manila can be configured to run in a single-node configuration or acrossmultiple nodes. Manila can be configured to provision shares from one or moreback ends. The OpenStack File Share service allows you to offer file-shareservices to users of an OpenStack installation.


1.Create the database.

mysql -u root -p
CREATE DATABASE manila;
GRANT ALL PRIVILEGES ON manila.* TO 'manila'@'localhost'IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON manila.* TO 'manila'@'%'IDENTIFIED BY 'password';

2.Create users, roles,service and API endpoint.

openstack user create --password-prompt manila
openstack role add --project service --user manila admin
openstack service create --name manila --description"OpenStack Shared Filesystems" share
openstack endpoint create \
  --publicurl http://x.x.x.x:8786/v1/%\(tenant_id\)s \
  --internalurl http://x.x.x.x:8786/v1/%\(tenant_id\)s \
  --adminurl http://x.x.x.x:8786/v1/%\(tenant_id\)s \
  --region RegionOne \
  share

3.Install required packages on controller node.openstack-manila-api and openstack-manila-scheduler services will run on thecontroller node.

1
yum install openstack-manila python-manilapython-manilaclient

4.Installed required packages on compute node.openstack-manila-share service will run on the compute node.

1
yum install openstack-mania-share python-manila

5. Edit the /etc/manila/manila.conf file and api-paste.ini
