OpenStack Queens : Configure Swift#3 (Storage Node)2018/06/19 |
|
Configure OpenStack Object Storage (Swift).
This example is based on the emvironment like follows.
-+---------------+----------------------------+------------
| | |
| eth0|10.0.0.30 eth0|10.0.0.50
| +-----------+-----------+ +-----------+-----------+
| | [ Control Node ] | | [ Proxy Node ] |
| | | | |
| | MariaDB RabbitMQ | | Swift Proxy |
| | Memcached httpd | | |
| | Keystone | | |
| +-----------------------+ +-----------------------+
|
+---------------+----------------------------+----------------------------+-----------
eth0|10.0.0.71 eth0|10.0.0.72 eth0|10.0.0.73
+-----------+-----------+ +-----------+-----------+ +-----------+-----------+
| [ Storage Node#1 ] | | [ Storage Node#2 ] | | [ Storage Node#3 ] |
| | | | | |
| Swift-Account | | Swift-Account | | Swift-Account |
| Swift-Container | | Swift-Container | | Swift-Container |
| Swift-Object | | Swift-Object | | Swift-Object |

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@snode01:~# apt -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 all Storage Node like follows. (the number [device*] is different on each Storage Nodes) |
|
root@snode01:~# 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@snode01:~# mkdir -p /srv/node/device0 root@snode01:~# mount -o noatime,nodiratime,nobarrier /dev/sdb1 /srv/node/device0 root@snode01:~# chown -R swift. /srv/node
root@snode01:~#
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@snode01:~# chown swift. /etc/swift/*.gz
root@snode01:~#
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@snode01:~#
vi /etc/swift/object-server.conf # line 6: make sure the value is follows bind_ip = 0.0.0.0 bind_port = 6000

|
| [5] | Start Swift services. |
