OpenStack Rocky : Configure Swift (Storage Node)2019/08/22 |
|
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 is 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 on all Storage Nodes. |
|
root@snode01:~# apt -y install swift swift-account swift-container swift-object
|
| [2] | Format free space of disk (/dev/sdb1 on this example) with EXT4 and mount on /var/lib/swift/node on all Storage Node like follows. |
|
root@snode01:~# mkfs.ext4 /dev/sdb1 root@snode01:~# mkdir /var/lib/swift/node root@snode01:~# mount -o noatime,nodiratime,nobarrier /dev/sdb1 /var/lib/swift/node root@snode01:~# chown -R swift. /var/lib/swift/node
root@snode01:~#
vi /etc/fstab # add to the end /dev/sdb1 /var/lib/swift/node ext4 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/ 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 # line 9,10: change (it's the value set on Proxy Node) swift_hash_path_suffix = swift_shared_path swift_hash_path_prefix = swift_shared_path
root@snode01:~#
vi /etc/swift/account-server.conf # line 3: change bind_port = 6002
# line 8: change devices = /var/lib/swift
root@snode01:~#
vi /etc/swift/container-server.conf # line 3: change bind_port = 6001
# line 8: change devices = /var/lib/swift
root@snode01:~#
vi /etc/swift/object-server.conf # line 3: change bind_port = 6000
# line 8: change devices = /var/lib/swift
root@snode01:~#

| [5] | Start Swift services. |
