OpenStack Swift1.4.x を10分で動かす(rpm/yum編)

とにかく速攻でSwiftを動かしてどんな感じか確かめてみたい人向け。

必要なもの

・Scientific Linux 6.1 x64(仮想環境上でも可能)
・ディスク空き10GBくらい
・インターネット接続

ディスクイメージの作成

# mkdir -p /swift/disk{0..4}

# for i in {0..4}
> do
> dd if=/dev/zero of=/mnt/disk$i bs=1024k count=1024
> done

# for i in {0..4}
> do
> mkfs.ext4 /mnt/disk$i
> done

パッケージの導入

# rpm -ihv http://yum.griddynamics.net/yum/master/openstack/openstack-repo-2011.3-0.2.noarch.rpm
# yum install -y openstack-swift* xinetd rsysnc memcached

デバイスのマウント

# for i in {0..4}
> do
> mount -o loop,noatime,nodiratime,user_xattr /mnt/disk$i /swift/disk$i
> done

# chown -R swift:swift /swift
