OpenStack Ussuri : Configure Swift (Storage Node)2020/06/17 |
|
Configure OpenStack Object Storage (Swift).
This example is based on the environment 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 are different each other. For storage partition, it needs enough size of free area on disks to create new partitions. |
|
| [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/device] on all Storage Node like follows. |
|
root@snode01:~# 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=1
= crc=1 finobt=1, sparse=0, rmapbt=0, reflink=0
data = bsize=4096 blocks=20971264, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0 ftype=1
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@snode01:~# mkdir -p /srv/node/device root@snode01:~# mount -o noatime,nodiratime /dev/sdb1 /srv/node/device root@snode01:~# chown -R swift. /srv/node
root@snode01:~#
vi /etc/fstab # add to the end /dev/sdb1 /srv/node/device xfs noatime,nodiratime 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:~#

root@snode01:~#

root@snode01:~#
vi /etc/swift/object-server.conf # line 6: confirm settings like follows bind_ip = 0.0.0.0 bind_port = 6000
root@snode01:~#
vi /etc/rsyncd.conf # create new
pid file = /var/run/rsyncd.pid
log file = /var/log/rsyncd.log
uid = swift
gid = swift
# specify the IP address of each storage node
address = 10.0.0.71
