This tutorial is based on the Ubuntu12.04 edition, and it will help readers build a openstack minimized installation. I am the top of the Wuyue, translation more use of transliteration method, so the individual words and the original discrepancy, please understand. I am not a major in English, I think the most important thing is to understand the technology, and not the four level and grind in the boring English-Chinese translation, so my goal is loya

Because I only focus on the part of openstack Object Storage, I did not write anything related to other modules (or I am relatively lazy). I may add it if necessary in the future.
The translation level is limited. If a netizen finds an error during re

Brief introduction:
There are four main components of Swift: Swift-proxy-server, Swift-account-server, Swift-container-server, Swift-object-server
