openstack-r版(rocky)搭建基于centos7.4 的openstack swift对象存储服务一

基础环境

本次使用环境使用vmware 搭建单节点openstack r版本，一台controller，一台compute，一台cinder，一台swift节点。

swift对象存储部署在3台机器中，分别为compute，cinder，swift，每台增加2块100G硬盘

简介

swift主要有四个组件：swift-proxy-server、swift-account-server、swift-container-server、swift-object-server

swift-proxy-server(代理服务):对外提供对象服务 API

swift-account-server(账户服务):提供账户元数据和统计信息，并维护所含容器列表的服务,管理由对象存储定义的账户

swift-container-server(容器服务):提供容器元数据和统计信息，并维护所含对象列表的服务

swift-object-server(对象服务):提供对象元数据和内容服务，每个对象的内容会以文件的形式存储在文件系统中，元数据会作为文件属性来存储，建议采用支持扩展属性的 XFS 文件系统

以下操作均在控制节点controller执行

前提已经安装完openstack所有核心服务

执行 . adminrc

　###创建swift用户服务端点等。

openstack user create --domain default --password-prompt swift

openstack role add --project service --user swift admin

openstack service create --name swift \
  --description "OpenStack Object Storage" object-store

openstack endpoint create --region RegionOne \
  object-store public http://controller:8080/v1/AUTH_%\(project_id\)s

openstack endpoint create --region RegionOne \
  object-store internal http://controller:8080/v1/AUTH_%\(project_id\)s

openstack endpoint create --region RegionOne \
  object-store admin http://controller:8080/v1
 
##安装服务

yum install openstack-swift-proxy python-swiftclient \
  python-keystoneclient python-keystonemiddleware \
  memcached -y
 
##从对象存储源存储库获取代理服务配置文件

curl -o /etc/swift/proxy-server.conf https://git.openstack.org/cgit/openstack/swift/plain/etc/proxy-server.conf-sample?h=stable/rocky

##编辑 /etc/swift/proxy-server.conf 文件 标红位置配置修改swift用户密码
