openstack学习笔记七 swift安装
项目--对象存储--容器 在容器里你创建的即使是一个文件夹，那么体现在硬盘里，也是一个文件，也就是对象object# openstack service list

[*] 容器 在容器里面创建对象
[*] 对象 文件就是对象
[*] 账户 权限
ring文件 保存到硬盘
[*] account.ring.gz 账户
[*] container.ring.gz 容器
[*] object.ring.gz 对象
保存到硬盘里的目录，这个目录为zone /srv/node/swiftloopback/ 挂载点 必须放在/srv/node/目录下
[*] zone1
[*] zone2 两个相同，备份
packstack方式安装完成后，上传一个文件，只在硬盘里保留一份
对象先映射到 虚拟节点/分区partition 2^n 再映射到zone
目的：减少数据的迁移量
swift服务
1 一致性服务 consisteny server
[*] auditor 定期扫描,如果出现问题，就把有问题的文件放隔离区
[*] replicate 从另外的zone复制相同的文件过来，实现数据同步
[*] update 如果replicate失效了，那么等段时间再试
2 代维服务proxy server
接受用户发送过来的请求，比如上传、删除等请求
3 存储服务
容器服务器 container server
对象服务器 objectserver
账户服务器 acount server
安装软件
# yum list openstack-swift*
# yum -y install openstack-swift.noarch openstack-swift-account.noarch openstack-swift-container.noarch openstack-swift-object.noarchopenstack-swift-proxy.noarch memcache*python-swiftclient 任何服务都要向keystone进行注册
# keystoneuser-create--name swift --passhequan
# keystone tenant-create--name services
# keystone user-role-add --user swift--tenant services --roleadmin
创建服务,指定endpoint
# keystone service-create--name swift --typeobject-store --description "swift"

创建ring文件的准备工作 创建模板，设定有几个备份，有多少分区。
# swift-ring-builder account.builder create 12 2 1
# swift-ring-builder object.builder create 12 2 1

# vim account-server.conf #3个都要改ip

# swift-ring-builder object.builderrebalance
# swift-ring-builder container.builderrebalance
# ls *.gz

任意一个分区挂了，还是可以正常查看
两个都挂了，就看不到了
