2015/12/28
 
Configure OpenStack Object Storage (Swift).
This example shows to configure like the environment below.

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] Enable Openstack Liberty's Repository and install them below on all Nodes.
root@storage01:~#
apt-get -y install swift swift-account swift-container swift-object xfsprogs
[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@storage01:~#
mkfs.xfs -i size=1024 -s size=4096 /dev/sdb1

meta-data=/dev/sdb1              isize=1024   agcount=4, agsize=1310656 blks
         =                       sectsz=4096  attr=2, projid32bit=0
data     =                       bsize=4096   blocks=5242624, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0
log      =internal log           bsize=4096   blocks=2560, version=2
         =                       sectsz=4096  sunit=1 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

root@storage01:~#
mkdir -p /srv/node/device0

root@storage01:~#
mount -o noatime,nodiratime,nobarrier /dev/sdb1 /srv/node/device0

root@storage01:~#
chown -R swift. /srv/node

root@storage01:~#
vi /etc/fstab
# add to the end

/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] Configure Swift and Rsync on all Storage Nodes.
root@storage01:~#
chown swift. /etc/swift/*.gz

root@storage01:~#
vi /etc/swift/swift.conf
# set the value which is set on Proxy Node

[swift-hash]
swift_hash_path_suffix = swift_shared_path
swift_hash_path_prefix = swift_shared_path
root@storage01:~#
vi /etc/swift/account-server.conf
# line 6: confirm settings

bind_ip = 0.0.0.0
bind_port = 6002
root@storage01:~#
vi /etc/swift/container-server.conf
# line 6: confirm settings

bind_ip = 0.0.0.0
bind_port = 6001
root@storage01:~#
vi /etc/swift/object-server.conf
# line 6: confirm settings

bind_ip = 0.0.0.0
bind_port = 6000
root@storage01:~#
