OpenStack Grizzly - Configure Swift#3 (Storage Node)
2013/08/23 |
|
Configure OpenStack Object Storage (Swift).
Swift consists 3 Nodes, it's Authentication Node, Proxy Node, Storage Node.
The example for Openstack of this site shows to configure All-in-One settings for Keystone, Glance, Cinder, Nova, Horizon, but on this Swift settings, configure a Node on another hosts like follows. (It uses Keystone Server as an Authentication Node)
|
+------------+ | +-----------+
| Auth Node |10.0.0.30 | 10.0.0.31| Proxy |
| (Keystone) |------------+------------| Node |
+------------+ | +-----------+
|
+------------------------+-----------------------+
| | |
|10.0.0.51 |10.0.0.52 |10.0.0.53
+-----------+ +-----------+ +-----------+
| Storage | | Storage | | Storage |
| Node1 |------------| Node2 |-----------| Node3 |
+-----------+ +-----------+ +-----------+
|
|
Configure Storage Node on here.
It's OK to set the same settings mostly on Storage Nodes, but IP address and Device number are different, though. Furthermore, add Hard drives on each Storage Nodes and create a partition "/dev/sdb1" for this settings. |

| [1] | Install Swift-Account, Swift-Container, Swift-Object. |

# install from EPEL OpenStack, EPEL [root@node01 ~]# yum --enablerepo=epel-openstack-grizzly,epel -y install openstack-swift-account openstack-swift-container openstack-swift-object xfsprogs xinetd rsync openssh-clients
|
| [2] | Format free space on disk (/dev/sdb1 on this example) with XFS and mount on /srv/node (the number "device*" is different on each Storage Nodes). |

| [3] | Copy Swift Ring file from Swift Proxy Node to this Storage Node. |
|
