Installing Swift from http://docs.openstack.org/developer/swift/ on Arch Linux

Swift is a highly available, distributed, and object-based storage system used in the OpenStack platform. Here is a quick guide on how to install Swift on an Arch Linux system.

1. Installation Requirements

Before moving to the installation process, ensure that the following dependencies are installed on the system:

• Python (>=2.7 or >=3.4)
• Cython
• PyECLib
• memcached
• rsync
• xfsprogs
• gcc

You can install these dependencies using the following command:

sudo pacman -S python cython pyeclib memcached rsync xfsprogs gcc

2. Installing Swift

3. Install the python2-setuptools package:

sudo pacman -S python2-setuptools

2. Download the latest Swift release from http://docs.openstack.org/developer/swift/:

wget https://tarballs.openstack.org/swift/swift-2.26.0.tar.gz

3. Extract the downloaded file:

tar xvzf swift-2.26.0.tar.gz
cd swift-2.26.0

4. Install Swift using the following command:

sudo python2 setup.py install

5. After installation, Swift artifacts will be located in the following directories:

/usr/local/bin/swift*
/usr/local/bin/st*     # object-server, object-replicator, object-auditor, container-reconciler
/usr/local/share/swift   # example configuration files, init scripts and systemd units

6. Configuring Swift

7. Copy the sample configuration files to the appropriate directories:

sudo cp /usr/local/share/swift/doc/saio/rsyncd.conf /etc/
sudo cp /usr/local/share/swift/doc/saio/swift.conf /etc/
sudo cp /usr/local/share/swift/doc/saio/proxy-server.conf /etc/swift/
sudo cp /usr/local/share/swift/doc/saio/account-server.conf /etc/swift/
sudo cp /usr/local/share/swift/doc/saio/container-server.conf /etc/swift/
sudo cp /usr/local/share/swift/doc/saio/object-server.conf /etc/swift/

2. Configure the Swift cluster:

sudo useradd -d /home/swift -s /bin/bash -m swift
echo "swift:swift" | sudo chpasswd
sudo chown -R swift:swift /srv
sudo chown -R swift:swift /etc/swift
sudo chmod 0755 /var/cache/swift
sudo chown -R swift:swift /var/cache/swift
sudo mkdir /var/run/swift
sudo chown -R swift:swift /var/run/swift
sudo cp /usr/local/share/swift/doc/saio/swift.conf /etc/swift/swift.conf

3. Modify the swift.conf file to suit your needs:

sudo nano /etc/swift/swift.conf

4. Restart the rsync service:

sudo systemctl enable rsyncd
sudo systemctl start rsyncd

5. Start the Swift services:

sudo systemctl enable swift-account-auditor.service swift-account-reaper.service swift-account-replicator.service swift-account.service swift-container-auditor.service swift-container-replicator.service swift-container-updater.service swift-container.service swift-object-auditor.service swift-object-replicator.service swift-object-updater.service swift-object.service swift-proxy.service
sudo systemctl start swift-object.service swift-proxy.service
sudo systemctl status swift-object.service swift-proxy.service

That's it, your Swift installation is complete. You can now use Swift on your Arch Linux system.
