硬盘分区

下面这块硬盘进行分区 ,记录分区的名字

[root@controller ~]# fdisk /dev/sdb 

Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Device does not contain a recognized partition table

Command (m for help): n
Partition type:
   p   primary (0 primary, 0 extended, 4 free)
   e   extended
Select (default p): p
Partition number (1-4, default 3): 3

参考文档：Linux 磁盘管理

注意：重启之后，需要重新配一下挂载源，具体可参考：OpenStack环境设计和系统准备

修改配置文件

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

[root@controller xiandian]# ls 

openrc.sh

[root@controller xiandian]# vi openrc.sh 

##--------------------Swift Config---------------------##
##Password for Keystore swift user. exmaple:000000
SWIFT_PASS=000000

##The NODE Object Disk for Swift. example:md126p4.
OBJECT_DISK=sdb3
#刚添加的分区的名称
##The NODE IP for Swift Storage Network. example:x.x.x.x.
STORAGE_LOCAL_NET_IP=10.0.0.11  
#计算或存储节点IP

安装SWIFT

[root@controller xiandian]# cd /usr/local/bin

控制节点：

[root@controller bin]# source /etc/keystone/admin-openrc.sh

[root@controller bin]# iaas-install-swift-controller.sh

计算节点：

执行脚本iaas-install-swift-compute.sh进行安装

执行过程中需要确认登录controller节点和输入controller节点root用户密码。

启动Swift

[root@controller swift]# source /etc/keystone/admin-openrc.sh

[root@controller swift]# swift-init all restart


[root@controller swift]# swift stat 

Account: AUTH_a06028e9f8e348d3b7a494a9d5cb0ee6
     Containers: 0
        Objects: 0
          Bytes: 0

   Content-Type: text/plain; charset=utf-8

Swift账号操作

查看当前账户

[root@controller swift]# swift stat 

Account: AUTH_a06028e9f8e348d3b7a494a9d5cb0ee6
     Containers: 0
        Objects: 0
          Bytes: 0

   Content-Type: text/plain; charset=utf-8
You have new mail in /var/spool/mail/root

Swift容器操作

创建容器

通过命令行实现对swift上数据的操作，首先需要创建一个名称为 ”xiandian”的容器

[root@controller bin]# openstack container create container02 

  +-------------------------------+-------------+--------------------------------+
| account                       | container   | x-trans-id                     |
+-------------------------------+-------------+--------------------------------+
| AUTH_a06028e9f8e348d3b7a494a9 | container02 | txae33a419f9bc4d19830d4-005cc5 |
| d5cb0ee6                      |             | d3ba                           |
+-------------------------------+-------------+--------------------------------+

列出所有容器

[root@controller ~]# openstack container list 

+-------------+
| Name        |
+-------------+
| container01 |
| container02 |
| maxin       |
| xiandain    |
| xiandian    |

获取容器元数据

[root@controller ~]# openstack container show container02 

 +--------------+---------------------------------------+
| Field        | Value                                 |
+--------------+---------------------------------------+
| account      | AUTH_a06028e9f8e348d3b7a494a9d5cb0ee6 |
| bytes_used   | 0                                     |
| container    | container02                           |
| object_count | 0                                     |

删除容器

[root@controller ~]# openstack container delete container02


Swift对象操作

上传文件

[root@controller bin]# touch file01

[root@controller bin]# openstack object create container02 file01 

+--------+-------------+----------------------------------+
| object | container   | etag                             |
+--------+-------------+----------------------------------+
| file01 | container01 | d41d8cd98f00b204e9800998ecf8427e |
+--------+-------------+----------------------------------+

上传之后，就可以在container02这个容器中找到文件：

[root@controller ~]# openstack object list container02 

+--------+
| Name   |
+--------+
| file01 |

</nowiki>

下载文件

[root@controller bin]# cd /mnt

[root@controller mnt]# ls 

centos  iaas

[root@controller mnt]# openstack object save container02 file01

[root@controller mnt]# ls 

centos  file01  iaas


查看容器内的对象

[root@controller bin]# openstack object list container02 

+--------+
| Name   |
+--------+
| file01 |

批量上传文件

[root@controller ~]# mkdir test

[root@controller ~]# cd test

[root@controller test]# touch 1.txt 2.txt

[root@controller test]# openstack object create container02 *.txt 

+--------+-------------+----------------------------------+
| object | container   | etag                             |
+--------+-------------+----------------------------------+
| 1.txt  | container02 | d41d8cd98f00b204e9800998ecf8427e |
| 2.txt  | container02 | d41d8cd98f00b204e9800998ecf8427e |
+--------+-------------+----------------------------------+
