OpenStack Rocky : Swift 設定#3 (Storage ノード)2019/08/22 |
|
OpenStack Object Storage（Swift）を設定します。
当例では以下のような環境を例に Swift サービスを設定します。
------------+---------------------------+-------------+---
| | |
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 |

Storage ノードの設定をします。基本的に台数分全て同じ設定で OK ですが、IPアドレスについては異なりますので、それぞれ注意して変更ください。
なお、当例では、Storage ノードとするサーバーにディスクを増設し、/dev/sdb1 にパーティションを作成して設定しています。 |
|
| [1] | 全 Storage ノード で Swift-Account, Swift-Container, Swift-Object 等々をインストールします。 |
|
root@snode01:~# apt -y install swift swift-account swift-container swift-object
|
| [2] | 全 Storage ノード でディスクの空き領域を EXT4 でフォーマットし、/var/lib/swift/node にマウントします。 |
|
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 # 最終行に追記 /dev/sdb1 /var/lib/swift/node ext4 noatime,nodiratime,nobarrier 0 0 |
| [3] | Proxy ノードから 全 Storage ノードへ Swift Ring ファイルをコピーします。 |
|
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] | 全 Storage ノードで Swift および Rsync の設定をします。 |
|
root@snode01:~# chown swift. /etc/swift/*.gz
root@snode01:~#
vi /etc/swift/swift.conf # 9,10行目：変更 (プロキシノードに設定したものと同じ値) swift_hash_path_suffix = swift_shared_path swift_hash_path_prefix = swift_shared_path
root@snode01:~#
vi /etc/swift/account-server.conf # 3行目：変更 bind_port = 6002
# 8行目：変更 devices = /var/lib/swift
root@snode01:~#
vi /etc/swift/container-server.conf # 3行目：変更 bind_port = 6001
# 8行目：変更 devices = /var/lib/swift
root@snode01:~#
vi /etc/swift/object-server.conf # 3行目：変更 bind_port = 6000
# 8行目：変更 devices = /var/lib/swift
root@snode01:~#
vi /etc/rsyncd.conf # 新規作成
pid file = /var/run/rsyncd.pid
log file = /var/log/rsyncd.log
uid = swift
gid = swift
# それぞれのノードの IPアドレス
address = 10.0.0.71

| [5] | 各サービスを起動します。 |
