本章將示範如何為你的備份用戶在 OpenStack 上設置 OpenStack 的儲存配額。
如果你未曾接觸過 OpenStack,你應該先參考他們在 http://docs.openstack.org/ 的常規設置文檔。
如果你已經有一個正在運行的 OpenStack,你可以按照我們的步驟來設置儲存限額。
這是在下列實例中使用的 OpenStack 版本:
這是在下列實例中使用的值:
注: Keystone admin 令牌的值可以在 Keystone 配置文件 /etc/keystone/keystone.conf 中的變量名 "admin_token" 找到。
請在安裝一個租戶(項目),用戶,角色和存儲配額等之前把下列的變量在 bash 配置文件及 proxy-server.conf 中的過濾器配置好。
步驟 1: 在 .bash_profile 中添加環境變量---------------------------------------------------------------------------------------------------- : : 修剪 : : export OS_USERNAME=admin export OS_PASSWORD=admin export OS_TENANT_NAME=mybackup export OS_AUTH_URL=http://10.7.54.7:5000/v2.0 export OS_SERVICE_ENDPOINT=http://10.7.54.7:35357/v2.0 export OS_SERVICE_TOKEN=7b05dab9722d44e7b9a82dc0d1ff74ea : : 修剪 : : ----------------------------------------------------------------------------------------------------
請重新登錄,配置文件方能生效。
注: OS_SERVICE_TOKEN 的值可以在 Keystone 配置文件 /etc/keystone/keystone.conf 中的變量名 "admin_token" 找到。
在 proxy-server.conf 中編輯文件,添加在下面以 紅色 的例子。
例如 (/etc/swift/proxy-server.conf)---------------------------------------------------------------------------------------------------- : : : 修剪 : : : [pipeline:main] pipeline = healthcheck cache authtoken keystone container-quotas account-quotas proxy-server : : : 修剪 : : : [filter:keystone] use = egg:swift#keystoneauth operator_roles = admin, SwiftOperator, ResellerAdmin is_admin = true [filter:container-quotas] use = egg:swift#container_quotas [filter:account-quotas] use = egg:swift#account_quotas ----------------------------------------------------------------------------------------------------
修改配置文件 /etc/swift/proxy-server.conf 後,重新啟動代理服務
例如---------------------------------------------------------------------------------------------------- [root@os ~]# swift-init proxy restart Signal proxy-server pid: 13453 signal: 15 proxy-server (13453) appears to have stopped Starting proxy-server...(/etc/swift/proxy-server.conf) WARNING: SSL should only be enabled for testing purposes. Use external SSL termination for a production deployment. [root@os ~]# ----------------------------------------------------------------------------------------------------
建立一個名為 ResellerAdmin 的用戶,以改變帳戶配額之用。你需要用 keystone 來建立一個角色,並添加到你的管理員用戶。
使用方法: keystone role-create --name <role-name>
例如---------------------------------------------------------------------------------------------------- [root@os ~]# keystone role-create --name ResellerAdmin WARNING: Bypassing authentication using a token & endpoint (authentication credentials are being ignored). +----------+----------------------------------+ | Property | Value | +----------+----------------------------------+ | id | 464e592192554bdd8201b367997886f1 | | name | ResellerAdmin | +----------+----------------------------------+ [root@os ~]# ----------------------------------------------------------------------------------------------------
請以下面的指令核實用戶角色的設置:
使用方法: keystone role-list
例如---------------------------------------------------------------------------------------------------- [root@os ~]# keystone role-list WARNING: Bypassing authentication using a token & endpoint (authentication credentials are being ignored). +----------------------------------+-----------------+ | id | name | +----------------------------------+-----------------+ | 464e592192554bdd8201b367997886f1 | ResellerAdmin | | e34c3a339a924180b07e2099842c727f | SwiftOperator | | 9fe2ff9ee4384b1894a90878d3e92bab | _member_ | | 3e61686683c94fd9a24beab378dfef81 | admin | +----------------------------------+-----------------+ [root@os ~]# ----------------------------------------------------------------------------------------------------
如果你想刪除用戶角色:
使用方法: keystone role-delete <role>
例如---------------------------------------------------------------------------------------------------- [root@os ~]# keystone role-delete ResellerAdmin WARNING: Bypassing authentication using a token & endpoint (authentication credentials are being ignored). [root@os ~]# ----------------------------------------------------------------------------------------------------
使用方法: keystone user-role-add --user <user> --role <role> --tenant <tenant>
例如---------------------------------------------------------------------------------------------------- [root@os ~]# keystone user-role-add --user admin --role ResellerAdmin --tenant mybackup WARNING: Bypassing authentication using a token & endpoint (authentication credentials are being ignored). [root@os ~]# ----------------------------------------------------------------------------------------------------
請以下面的指令核實設置:
使用方法: keystone user-role-list --user <user> --tenant <tenant>
例如---------------------------------------------------------------------------------------------------- [root@os ~]# keystone user-role-list --user admin --tenant mybackup WARNING: Bypassing authentication using a token & endpoint (authentication credentials are being ignored). +----------------------------------+-----------------+----------------------------------+----------------------------------+ | id | name | user_id | tenant_id | +----------------------------------+-----------------+----------------------------------+----------------------------------+ | 464e592192554bdd8201b367997886f1 | ResellerAdmin | 70a0cf53001d4798b02aae61e935e5df | 49f2482ecff9431bae1d32fa2a004026 | | 3e61686683c94fd9a24beab378dfef81 | admin | 70a0cf53001d4798b02aae61e935e5df | 49f2482ecff9431bae1d32fa2a004026 | +----------------------------------+-----------------+----------------------------------+----------------------------------+ [root@os ~]# ----------------------------------------------------------------------------------------------------
如果你想刪除授予的角色:
使用方法: keystone user-role-remove --user <user> --role <role> --tentant <tentant>
例如---------------------------------------------------------------------------------------------------- [root@os ~]# keystone user-role-remove --user admin --role ResellerAdmin --tenant mybackup WARNING: Bypassing authentication using a token & endpoint (authentication credentials are being ignored). [root@os ~]# ----------------------------------------------------------------------------------------------------
在這個例子中,我們將套用10GB於這個租戶(項目)。該項目中的所有容器將分享這一個配額。
使用方法: swift post -m quota-bytes:<value>
例如---------------------------------------------------------------------------------------------------- [root@os ~]# swift post -m quota-bytes:10737418240 [root@os ~]# ----------------------------------------------------------------------------------------------------
請以下面的指令核實存儲配額的設置:
使用方法: swift stat
例如
---------------------------------------------------------------------------------------------------- [root@os ~]# swift stat Account: AUTH_49f2482ecff9431bae1d32fa2a004026 Containers: 4 Objects: 260 Bytes: 694896 Meta Quota-Bytes: 10737418240 X-Timestamp: 1412574345.10669 Content-Type: text/plain; charset=utf-8 Accept-Ranges: bytes [root@os ~]# ----------------------------------------------------------------------------------------------------
如果你想刪除這個租戶(項目)的存儲配額:
使用方法: swift post -m quota-bytes:
例如---------------------------------------------------------------------------------------------------- [root@os ~]# swift post -m quota-bytes: [root@os ~]# ----------------------------------------------------------------------------------------------------
為此用戶使用此容器時設置存儲配額,如: 套用 2GB 到 user1
使用方法: swift post <container name> -H "X-Container-Meta-Quota-Bytes: <size in bytes>"
例如---------------------------------------------------------------------------------------------------- [root@os ~]# swift post user1 -H "X-Container-Meta-Quota-Bytes: 2147483648" [root@os ~]# ----------------------------------------------------------------------------------------------------
請以下面的指令核實存儲配額的設置:
使用方法: swift stat <container name>
例如---------------------------------------------------------------------------------------------------- [root@os ~]# swift stat user1 Account: AUTH_49f2482ecff9431bae1d32fa2a004026 Container: user1 Objects: 0 Bytes: 0 Read ACL: mybackup:user1 Write ACL: mybackup:user1 Sync To: Sync Key: Meta Quota-Bytes: 2147483648 Accept-Ranges: bytes X-Timestamp: 1412578586.50844 Content-Type: text/plain; charset=utf-8 [root@os ~]# ----------------------------------------------------------------------------------------------------
如果你想刪除這個用戶的存儲配額:
使用方法: swift post <container name> -H "X-Container-Meta-Quota-Bytes:"
例如---------------------------------------------------------------------------------------------------- [root@os ~]# swift post user6 -H "X-Container-Meta-Quota-Bytes:" [root@os ~]# ----------------------------------------------------------------------------------------------------
