OpenStack Icehouse : Configure Swift#3 (Storage Node)
2014/06/11 |
|
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@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:~# for ringtype in account container object; do
service swift-$ringtype start
for service in replicator updater auditor; do
