OpenStack Icehouse : Configure Swift#3 (Storage Node)
2014/06/28 |
Configure OpenStack Object Storage (Swift).
This example shows to configure like the environment below.
| +------------------+ | +-----------------+ | [ Control Node ] |10.0.0.30 | 10.0.0.70| [ Proxy Node ] | | Keystone |-----------+-----------| | +------------------+ | +-----------------+ | +---------------------------+--------------------------+ | | | |10.0.0.71 |10.0.0.72 |10.0.0.73 +-------+----------+ +--------+---------+ +--------+---------+ | [Storage Node#1] | | [Storage Node#2] | | [Storage Node#3] | | |-------| |-------| | +------------------+ +------------------+ +------------------+ |
Configure Storage Node on this section.
It's OK to set the same settings mostly on all Storage Nodes,
but only IP address and Device number are different each other, 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 and others on all Storage Node like follows. |
[root@node01 ~]# yum --enablerepo=openstack-icehouse,epel -y install openstack-swift-account openstack-swift-container openstack-swift-object xfsprogs xinetd rsync openssh-clients
|
[2] | Format free space of disk (/dev/sdb1 on this example) with XFS and mount on srv/node on allStorage Node like follows. (the number "device*" is different on each Storage Nodes) |
[root@node01 ~]# mkfs.xfs -i size=1024 -s size=4096 /dev/sdb1 meta-data=/dev/sdb1 isize=1024 agcount=4, agsize=6553514 blks = sectsz=4096 attr=2, projid32bit=0 data = bsize=4096 blocks=26214055, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 log =internal log bsize=4096 blocks=12799, version=2 = sectsz=4096 sunit=1 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0[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 line /dev/sdb1 /srv/node/device0 xfs noatime,nodiratime,nobarrier 0 0 |
[3] | Copy Swift Ring files from the Swift Proxy Node to all Storage Nodes. |
[root@proxy ~]# scp /etc/swift/*.gz 10.0.0.71:/etc/swift/ root@10.0.0.71's password: account.ring.gz 100% 3912 3.8KB/s 00:00 container.ring.gz 100% 3904 3.8KB/s 00:00 object.ring.gz 100% 3895 3.8KB/s 00:00 |
[4] | Change ownership for Swift Ring files on all Storage Nodes. |
[root@node01 ~]# chown swift. /etc/swift/*.gz |
[5] | Configure Swift and Rsync on all Storage Nodes. |
[root@node01 ~]#
