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

映射 ：ring（环） 映射到硬盘

1. 容器 在容器里面创建对象

2. 对象 文件就是对象

3. 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 object server

账户服务器 acount server

安装软件

[root@h4~]#yumlistopenstack-swift*
[root@h4~]#yum-yinstallopenstack-swift.noarchopenstack-swift-account.noarchopenstack-swift-container.noarchopenstack-swift-object.noarchopenstack-swift-proxy.noarchmemcache*python-swiftclient

任何服务都要向keystone进行注册

[root@h4~(keystone_admin)]#keystoneuser-create--nameswift--passhequan
[root@h4~(keystone_admin)]#keystonetenant-create--nameservices
[root@h4~(keystone_admin)]#keystoneuser-role-add--userswift--tenantservices--roleadmin

创建服务,指定endpoint

[root@h4~(keystone_admin)]#keystoneservice-create--nameswift--typeobject-store--description"swift"
keystoneendpoint-create--service-id0995c9a9ed4847da86435bca9a7be8fc--publicurl'http://192.168.1.204:8080/v1/AUTH_%(tenant_id)s'--internalurl'http://192.168.1.204:8080/v1/AUTH_%(tenant_id)s'--adminurl'http://192.168.1.204:8080'

配置swift 准备了2个分区

zone1zone2在/srv/node
12/dev/sdb1/srv/node/zone1xfsdefaults00##挂载
13/dev/sdb2/srv/node/zone2xfsdefaults00

[root@h4~(keystone_admin)]#chown-Rswift.swift/srv/node/

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。

[root@h4swift(keystone_admin)]#swift-ring-builderaccount.buildercreate1221
[root@h4swift(keystone_admin)]#swift-ring-builderobject.buildercreate1221
[root@h4swift(keystone_admin)]#swift-ring-buildercontainer.buildercreate1221

指定映射位置

[root@h4swift]#vimaccount-server.conf#3个都要改ip
6bind_ip=192.168.1.204
[root@h4swift(keystone_admin)]#swift-ring-builderaccount.builderaddz1-192.168.1.204:6202/zone1100

[root@h4swift(keystone_admin)]#swift-ring-buildercontainer.builderaddz2-192.168.1.204:6201/zone2100

创建ring文件

[root@h4swift(keystone_admin)]#swift-ring-builderaccount.builderrebalance
[root@h4swift(keystone_admin)]#swift-ring-builderobject.builderrebalance
[root@h4swift(keystone_admin)]#swift-ring-buildercontainer.builderrebalance
[root@h4swift(keystone_admin)]#ls*.gz
account.ring.gzcontainer.ring.gzobject.ring.gz

启动服务

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
