OpenStack Ocata : Swift 設定#3 (Storage ノード)2017/03/16 |
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 | +-----------------------+ +-----------------------+ +-----------------------+ |
ここでは Storage ノードの設定をします。
Storage ノードは、基本的に台数分全て同じ設定で OK ですが、IPアドレスやデバイス名の数字については異なりますので、それぞれ注意して変更してください。 なお、この例では、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-get -y install swift swift-account swift-container swift-object xfsprogs
|
[2] | 全 Storage ノード でディスクの空き領域を XFS でフォーマットし、/srv/node にマウントします。 (「device*」の数字は Storage ノードごとに異なる箇所です) |
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=0root@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 # 最終行に追記 /dev/sdb1 /srv/node/device0 xfs 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/ 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] | 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 # プロキシノードに設定したものと同じ値 [swift-hash] swift_hash_path_suffix = swift_shared_path swift_hash_path_prefix = swift_shared_path
root@snode01:~#
vi /etc/swift/account-server.conf # 6行目:設定確認 bind_ip = 0.0.0.0 bind_port = 6002

root@snode01:~#
vi /etc/swift/object-server.conf # 6行目:設定確認 bind_ip = 0.0.0.0 bind_port = 6000
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 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@snode01:~#
vi /etc/default/rsync # 8行目:変更 RSYNC_ENABLE= true
|
[5] | 各サービスを起動します。 |
