2014/06/11
 
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] Install Swift-Account, Swift-Container, Swift-Object and others on all Storage Node like follows.
root@swift01:~#
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@swift01:~#
mkfs.xfs -i size=1024 -s size=4096 /dev/sdb1

meta-data=/dev/sdb1              isize=1024   agcount=4, agsize=5242816 blks
         =                       sectsz=4096  attr=2, projid32bit=0
data     =                       bsize=4096   blocks=20971264, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0
log      =internal log           bsize=4096   blocks=10239, version=2
         =                       sectsz=4096  sunit=1 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

root@swift01:~#
mkdir -p /srv/node/device0

root@swift01:~#
mount -o noatime,nodiratime,nobarrier /dev/sdb1 /srv/node/device0

root@swift01:~#
chown -R swift. /srv/node

root@swift01:~#
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% 3882     3.8KB/s   00:00
container.ring.gz             100% 3864     3.8KB/s   00:00
object.ring.gz                100% 3883     3.8KB/s   00:00
[4] Change ownership for Swift Ring files on all Storage Nodes.
root@swift01:~#
chown swift. /etc/swift/*.gz

[5] Configure Swift and Rsync on all Storage Nodes.
root@swift01:~#
vi /etc/swift/swift.conf
# create new

# 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@swift01:~#
vi /etc/rsyncd.conf
# create new like follows

pid file = /var/run/rsyncd.pid
log file = /var/log/rsyncd.log
uid = swift
gid = swift
address = 10.0.0.71

[account]
path            = /srv/node
read only       = false
write only      = no
list            = yes
incoming chmod  = 0644
outgoing chmod  = 0644
max connections = 25
lock file =     /var/lock/account.lock

[container]
path            = /srv/node
read only       = false
write only      = no
list            = yes
incoming chmod  = 0644
outgoing chmod  = 0644
max connections = 25
lock file =     /var/lock/container.lock

[object]
path            = /srv/node
read only       = false
write only      = no
list            = yes
incoming chmod  = 0644
outgoing chmod  = 0644
max connections = 25
lock file =     /var/lock/object.lock

[swift_server]
path            = /etc/swift
read only       = true
write only      = no
list            = yes
incoming chmod  = 0644
outgoing chmod  = 0644
max connections = 5
lock file =     /var/lock/swift_server.lock

root@swift01:~#
vi /etc/default/rsync
# line 8: change

RSYNC_ENABLE=
true
[6] Start Swift services.
root@swift01:~#
/etc/init.d/rsync start

* Starting rsync daemon rsync
root@swift01:~#

    service swift-$ringtype start
    for service in replicator updater auditor; do
