OpenStack-M版(Mitaka)搭建基于（Centos7.2）+++十、Openstack对象存储服务（swift）下

十、Openstack对象存储服务（swift）下

控制节点上执行

一、创建账户（account）ring

1.切换到 /etc/swift目录

[root@controller ~]# cd /etc/swift/[root@controller swift]# 

2.创建基本 account.builder 文件
swift-ring-builder account.builder create 10 1 1

参数解释：

（10）Ring的分区数

（1）表示副本数（我本来一个都不想要的结果要求至少一个副本）

（1）表示分区数据的迁移时间为1小时

[root@controller swift]# swift-ring-builder account.builder create 10 1 1

此操作无返回

3.添加每个节点到 ring 中
swift-ring-builder account.builder add --region 1 --zone 1 --ip 192.168.100.20 --port 6002 --device sdb --weight 10

swift-ring-builder account.builder add --region 1 --zone 1 --ip 192.168.100.20 --port 6002 --device sdc --weight 10

--ip(存储节点管理网络ip我这里是安装在计算节点上所以是计算节点管理网络ip)

--port（ 端点）

--device （存储设备名称）

--weight （存储设备大小）

[root@controller swift]# swift-ring-builder account.builder add \> --region 1 --zone 1 --ip 192.168.100.20 --port 6002 --device sdb --weight 10Device d0r1z1-192.168.100.20:6002R192.168.100.20:6002/sdb_"" with 10.0 weight got id 0[root@controller swift]# swift-ring-builder account.builder add \> --region 1 --zone 1 --ip 192.168.100.20 --port 6002 --device sdc --weight 10Device d1r1z1-192.168.100.20:6002R192.168.100.20:6002/sdc_"" with 10.0 weight got id 1

4.验证 ring 的内容

swift-ring-builder account.builder

[root@controller swift]# swift-ring-builder account.builderaccount.builder, build version 21024 partitions, 1.000000 replicas, 1 regions, 1 zones, 2 devices, 100.00 balance, 0.00 dispersionThe minimum number of hours before a partition can be reassigned is 1 (0:00:00 remaining)The overload factor is 0.00% (0.000000)Ring file account.ring.gz not found, probably it hasn't been written yetDevices:    id  region  zone      ip address  port  replication ip  replication port      name weight partitions balance flags meta             0       1     1  192.168.100.20  6002  192.168.100.20              6002       sdb  10.00          0 -100.00                    1       1     1  192.168.100.20  6002  192.168.100.20              6002       sdc  10.00          0 -100.00       

5.平衡 ring

swift-ring-builder account.builder rebalance

[root@controller swift]# swift-ring-builder account.builder rebalanceReassigned 1024 (100.00%) partitions. Balance is now 0.00.  Dispersion is now 0.00

二、创建容器（container）ring

1.创建基本 container.builder 文件
swift-ring-builder container.builder create 10 1 1

参数解释：

（10）Ring的分区数

（1）表示副本数（我本来一个都不想要的结果要求至少一个副本）

（1）表示分区数据的迁移时间为1小时

[root@controller swift]# swift-ring-builder container.builder create 10 1 1

此操作无返回

2.添加每个节点到 ring 中
swift-ring-builder container.builder add --region 1 --zone 1 --ip 192.168.100.20 --port 6001 --device sdb --weight 10

swift-ring-builder container.builder add --region 1 --zone 1 --ip 192.168.100.20 --port 6001 --device sdc --weight 10

--ip(存储节点管理网络ip我这里是安装在计算节点上所以是计算节点管理网络ip)

--port（ 端点）

--device （存储设备名称）

--weight （存储设备大小）

[root@controller swift]# swift-ring-builder container.builder add --region 1 --zone 1 --ip 192.168.100.20 --port 6001 --device sdb --weight 10Device d0r1z1-192.168.100.20:6001R192.168.100.20:6001/sdb_"" with 10.0 weight got id 0[root@controller swift]# swift-ring-builder container.builder add --region 1 --zone 1 --ip 192.168.100.20 --port 6001 --device sdc --weight 10Device d1r1z1-192.168.100.20:6001R192.168.100.20:6001/sdc_"" with 10.0 weight got id 1

3.验证 ring 的内容

swift-ring-builder container.builder

[root@controller swift]# swift-ring-builder container.buildercontainer.builder, build version 21024 partitions, 1.000000 replicas, 1 regions, 1 zones, 2 devices, 100.00 balance, 0.00 dispersionThe minimum number of hours before a partition can be reassigned is 1 (0:00:00 remaining)The overload factor is 0.00% (0.000000)Ring file container.ring.gz not found, probably it hasn't been written yetDevices:    id  region  zone      ip address  port  replication ip  replication port      name weight partitions balance flags meta             0       1     1  192.168.100.20  6001  192.168.100.20              6001       sdb  10.00          0 -100.00                    1       1     1  192.168.100.20  6001  192.168.100.20              6001       sdc  10.00          0 -100.00       

4.平衡 ring

swift-ring-builder container.builder rebalance

[root@controller swift]# swift-ring-builder container.builder rebalanceReassigned 1024 (100.00%) partitions. Balance is now 0.00.  Dispersion is now 0.00

三、创建对象（object）ring

1.创建基本 object.builder 文件
swift-ring-builder object.builder create 10 1 1

参数解释：

（10）Ring的分区数

（1）表示副本数（我本来一个都不想要的结果要求至少一个副本）

（1）表示分区数据的迁移时间为1小时

[root@controller swift]# swift-ring-builder object.builder create 10 1 1

此操作无返回

2.添加每个节点到 ring 中
swift-ring-builder object.builder add --region 1 --zone 1 --ip 192.168.100.20 --port 6000 --device sdb --weight 10

swift-ring-builder object.builder add --region 1 --zone 1 --ip 192.168.100.20 --port 6000 --device sdc --weight 10

--ip(存储节点管理网络ip我这里是安装在计算节点上所以是计算节点管理网络ip)

--port（ 端点）

--device （存储设备名称）

--weight （存储设备大小）

[root@controller swift]# swift-ring-builder object.builder add --region 1 --zone 1 --ip 192.168.100.20 --port 6001 --device sdb --weight 10Device d0r1z1-192.168.100.20:6001R192.168.100.20:6000/sdb_"" with 10.0 weight got id 0[root@controller swift]# swift-ring-builder object.builder add --region 1 --zone 1 --ip 192.168.100.20 --port 6001 --device sdc --weight 10Device d1r1z1-192.168.100.20:6001R192.168.100.20:6000/sdc_"" with 10.0 weight got id 1

3.验证 ring 的内容

swift-ring-builder object.builder

[root@controller swift]# swift-ring-builder object.builderobject.builder, build version 21024 partitions, 1.000000 replicas, 1 regions, 1 zones, 2 devices, 100.00 balance, 0.00 dispersionThe minimum number of hours before a partition can be reassigned is 1 (0:00:00 remaining)The overload factor is 0.00% (0.000000)Ring file object.ring.gz not found, probably it hasn't been written yetDevices:    id  region  zone      ip address  port  replication ip  replication port      name weight partitions balance flags meta             0       1     1  192.168.100.20  6001  192.168.100.20              6000       sdb  10.00          0 -100.00                    1       1     1  192.168.100.20  6001  192.168.100.20              6000       sdc  10.00          0 -100.00       

4.平衡 ring

swift-ring-builder object.builder rebalance

[root@controller swift]# swift-ring-builder object.builder rebalanceReassigned 1024 (100.00%) partitions. Balance is now 0.00.  Dispersion is now 0.00

四、将文件发送到存储节点（我这里计算节点就是存储节点）

文件：object.ring.gz account.ring.gz container.ring.gz

scp *.gz 192.168.100.20:/etc/swift/

[root@controller swift]# scp *.gz 192.168.100.20:/etc/swift/The authenticity of host '192.168.100.20 (192.168.100.20)' can't be established.ECDSA key fingerprint is 5a:43:e9:cb:f4:eb:b4:b4:e6:26:1a:5a:f2:f3:55:56.Are you sure you want to continue connecting (yes/no)? yesWarning: Permanently added '192.168.100.20' (ECDSA) to the list of known hosts.root@192.168.100.20's password: account.ring.gz                                                                                                                                             100%  455     0.4KB/s   00:00    container.ring.gz                                                                                                                                           100%  448     0.4KB/s   00:00    object.ring.gz                                                                                                                                              100%  442     0.4KB/s   00:00    

可以在存储节点 /etc/swift 目录下查看是否有文件

[root@compute ~]# cd /etc/swift/[root@compute swift]# lsaccount.ring.gz  account-server  account-server.conf  container.ring.gz  container-server  container-server.conf  object.ring.gz  object-server  object-server.conf  swift.conf

五、配置swift.conf 文件

1.从对象存储源仓库中获取 /etc/swift/swift.conf 文件

curl -o /etc/swift/swift.conf https://git.openstack.org/cgit/openstack/swift/plain/etc/swift.conf-sample

[root@controller swift]# curl -o /etc/swift/swift.conf   https://git.openstack.org/cgit/openstack/swift/plain/etc/swift.conf-sample  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current                                 Dload  Upload   Total   Spent    Left  Speed100  7894  100  7894    0     0   6718      0  0:00:01  0:00:01 --:--:--  6729

2.修改配置文件/etc/swift/swift.conf

vi /etc/swift/swift.conf

vi /etc/swift/swift.conf配置哈希路径前缀和后缀(获取的配置文件有默认值不用改)swift_hash_path_suffix = changemeswift_hash_path_prefix = changeme配置默认存储策略（获取的配置文件中这两个值是打开的其实不用管）[storage-policy:0]name = Policy-0default = yes

3.复制swift.conf文件到每个存储节点（我这里计算节点就是存储节点）

scp swift.conf 192.168.100.20:/etc/swift

[root@controller swift]# scp swift.conf 192.168.100.20:/etc/swiftroot@192.168.100.20's password: swift.conf                                                                                                                                                  100% 7894     7.7KB/s   00:00    

4.在所有节点上，赋予配置文件目录合适的所有权

chown -R root:swift /etc/swift

(控制节点)[root@controller swift]# chown -R root:swift /etc/swift（存储结点【计算节点】）[root@compute swift]# chown -R root:swift /etc/swift
