OpenStack Havana - Configure Swift#3 (Storage Node)2013/10/28 |
|
Configure OpenStack Object Storage (Swift).
This example configures with the environment below.
|
+------------+ | +-----------+
| Auth Node |10.0.0.30 | 10.0.0.50| Proxy |
| (Keystone) |------------+------------| Node |
+------------+ | +-----------+
|
+------------------------+-----------------------+
| | |
|10.0.0.51 |10.0.0.52 |10.0.0.53
+-----------+ +-----------+ +-----------+
| Storage | | Storage | | Storage |
| Node1 |------------| Node2 |-----------| Node3 |
+-----------+ +-----------+ +-----------+

Configure Storage Node in this section.
It's OK to set the same settings mostly on all 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=openstack-havana,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). |
|
[root@node01 ~]# mkfs.xfs -i size=1024 /dev/sdb1

[root@node01 ~]# mkdir -p /srv/node/device0 [root@node01 ~]# mount -o noatime,nodiratime,nobarrier /dev/sdb1 /srv/node/device0 [root@node01 ~]# chown -R swift. /srv/node
[root@node01 ~]#
vi /etc/fstab # add at the last /dev/sdb1 /srv/node/device0 xfs noatime,nodiratime,nobarrier 0 0 |
| [3] | Copy Swift Ring file from Swift Proxy Node to this Storage Node. |
|
[root@proxy ~]# scp /etc/swift/*.gz 10.0.0.51:/etc/swift/ The authenticity of host '10.0.0.51 (10.0.0.51)' can't be established. RSA key fingerprint is xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:f3:ed:54.

| [4] | Change owner for Swift Ring file. |
|
[root@node01 ~]# chown swift. /etc/swift/*.gz |
| [5] | Configure Swift and Rsync. |
