= Installing Object Storage (Swift) = You can provide cloud-based object storage for archival backups, content delivery networks (CDN), and more scalable, high-availability, high-performing storage use cases. Here's how to install it.

Pre-requisites for Swift
Object Storage (Swift) is intended to run on commodity hardware, meaning any computers that run Linux or Windows typically will do. Generally we do not recommend RAID due to performance degradation since it doesn't match Swift's design well.

You can install Swift with an all-in-one virtual machine by following instructions here: http://swift.openstack.org/development_saio.html.

Installing Swift (packaged release)
Step 1: Downloading the Swift packaged software 

Download the released package at http://launchpad.net/swift/1.1/1.1.0-rc/+download/swift-1.1.0-rc1.tar.gz.

Extract the file to the server where you want to install and run Swift. For a multi-server installation you can copy the files where you need them.

tar xvzf swift-1.1.0-rc1.tar.gz

 Step 2: Compile the code Switch to the directory where you extracted the Swift code and then run this python install command.

sudo python setup.py install

 Step 3: Generate the ring files, add devices to the ring, and rebalance 

You use the swift-ring-builder command line tool to build the ring. Here are scripts to ready Swift for action.

~/bin/resetswift.


 * 1) !/bin/bash

swift-init all stop sleep 5 sudo umount /mnt/sdb1 sudo mkfs.xfs -f -i size=1024 /dev/sdb1 sudo mount /mnt/sdb1 sudo mkdir /mnt/sdb1/1 /mnt/sdb1/2 /mnt/sdb1/3 /mnt/sdb1/4 /mnt/sdb1/test sudo chown : /mnt/sdb1/* mkdir -p /srv/1/node/sdb1 /srv/2/node/sdb2 /srv/3/node/sdb3 /srv/4/node/sdb4 sudo rm -f /var/log/debug /var/log/messages /var/log/rsyncd.log /var/log/syslog sudo service rsyslog restart sudo service memcached restart

~/bin/remakerings:


 * 1) !/bin/bash

cd /etc/swift

rm -f *.builder *.ring.gz backups/*.builder backups/*.ring.gz

~/bin/startmain:


 * 1) !/bin/bash

swift-init auth-server start swift-init proxy-server start swift-init account-server start swift-init container-server start swift-init object-server start

~/bin/startrest:


 * 1) !/bin/bash

swift-auth-recreate-accounts -K devauth swift-init object-updater start swift-init container-updater start swift-init object-replicator start swift-init container-replicator start swift-init account-replicator start swift-init object-auditor start swift-init container-auditor start swift-init account-auditor start swift-init account-reaper start
 * 1) Replace devauth with whatever your super_admin key is (recorded in
 * 2) /etc/swift/auth-server.conf).

 Step 4: Create configuration files for each server 

 Step 4: Start Swift 
 * 1) Create a startup script, such as:

swift-init auth-server start swift-init proxy-server start swift-init account-server start swift-init container-server start swift-init object-server start
 * 1) !/bin/bash


 * 1) Give execute permissions for the files in /bin.
