九、Swift对象存储服务(双节点搭建)

要求:Controoler节点需要2块空盘

Compute节点需要再加2块空盘

本次搭建采用Controller 和 Compute双节点节点做swift组件

1.Controller安装并配置控制节点

2.Compute安装和配置存储节点

3.Compute节点安装并配置组件

4.Controller节点创建，分发并初始化rings

5.启动服务

6.Controller执行验证操作

1.Controller安装并配置控制节点

#### 1.获得凭证并创建身份认证服务的凭证

# . /root/admin-openrc

# openstack user create --domain default --password 000000 swift

# openstack role add --project service --user swift admin

# openstack service create --name swift --description "OpenStack Object Storage" object-store

创建对象存储服务 API 端点

# openstack endpoint create --region RegionOne object-store public http://controller:8080/v1/AUTH_%\(tenant_id\)s

# openstack endpoint create --region RegionOne object-store internal http://controller:8080/v1/AUTH_%\(tenant_id\)s

# openstack endpoint create --region RegionOne object-store admin http://controller:8080/v1



3.安装并配置组件

[root@controller ~]# yum -y install openstack-swift-proxy python-swiftclient python-keystoneclient python-keystonemiddleware memcached xfsprogs rsync openstack-swift-account openstack-swift-container openstack-swift-object

查看空盘
lsblk

每个盘划分一个空白分区

# fdisk /dev/sdb

# fdisk /dev/sdc



创建挂载目录

[root@controller ~]# mkdir -p /swift/sdb

[root@controller ~]# mkdir -p /swift/sdc

指定分区格式

挂载分区到目录

添加到/etc/fstab配置文件中

[root@controller ~]# vi /etc/fstab

/dev/sdb1 /swift/sdb xfs noatime,nodiratime,nobarrier,logbufs=8 0 0

/dev/sdc1 /swift/sdc xfs noatime,nodiratime,nobarrier,logbufs=8 0 0

编辑配置文件 /etc/rsyncd.conf

[root@controller ~]# vi /etc/rsyncd.conf

启动服务

[root@controller ~]# systemctl start rsyncd.service

[root@controller ~]# systemctl enable rsyncd.service

6.赋权：

# mkdir -p /var/cache/swift

# chown -R root:swift /var/cache/swift

# chmod -R 775 /var/cache/swift

# chown -R swift:swift /swift

# chown -R root:swift /etc/swift

编辑三个配置文件account container object

2.Compute安装和配置存储节点

1.安装软件包

[root@compute ~]# yum -y install xfsprogs rsync openstack-swift-account openstack-swift-container openstack-swift-object

搭建Swift Compute节点需要两块空盘，此处我们查看添加的空盘

# lsblk

创建分区

# fdisk /dev/sdc

# fdisk /dev/sdd



指定文件格式

# mkfs.xfs /dev/sdc1

# mkfs.xfs /dev/sdd1

3.创建挂载点目录结构：

[root@compute ~]# mkdir -p /swift/sdc

[root@compute ~]# mkdir -p /swift/sdd

挂载分区到目录

[root@compute ~]# mount /dev/sdc1 /swift/sdc/

[root@compute ~]# mount /dev/sdd1 /swift/sdd/

4.编辑/etc/fstab文件并添加以下内容：

vi /etc/fstab

/dev/sdd1 /swift/sdd xfs noatime,nodiratime,nobarrier,logbufs=8 0 0

5.编辑/etc/rsyncd.conf文件并添加以下内容：

[root@compute ~]#vi /etc/rsyncd.conf

pid file = /var/run/rsyncd.pid

log file = /var/log/rsyncd.log

uid = swift

gid = swift

address = 192.168.100.20

[account]

path            = /swift

read only       = false

write only      = no

list            = yes

incoming chmod  = 0644

outgoing chmod  = 0644

max connections = 25

lock file =     /var/lock/account.lock

[container]

path            = /swift

read only       = false

write only      = no

list            = yes

incoming chmod  = 0644

outgoing chmod  = 0644

max connections = 25

lock file =     /var/lock/container.lock

[object]

path            = /swift

outgoing chmod  = 0644

max connections = 25

lock file =     /var/lock/object.lock

6.启动 “rsyncd” 服务和配置它随系统启动：

# systemctl start rsyncd.service

# systemctl enable rsyncd.service

6.赋权：

# mkdir -p /var/cache/swift

# chown -R root:swift /var/cache/swift

# chmod -R 775 /var/cache/swift

# chown -R swift:swift /swift

# chown -R root:swift /etc/swift

[swift-constraints]

3.Controller 和 Compute节点安装并配置组件

4.Controller节点创建，分发并初始化rings

1.创建账户ring

1.切换到 ``/etc/swift``目录。创建基本 account.builder 文件：

# cd /etc/swift

# swift-ring-builder account.builder create 18 1 1

2.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 sdc1 --weight 100

# swift-ring-builder account.builder add --region 1 --zone 1 --ip 192.168.100.20 --port 6002 --device sdd1 --weight 100

# swift-ring-builder account.builder add --region 1 --zone 1 --ip 192.168.100.10 --port 6002 --device sdc1 --weight 100

# swift-ring-builder account.builder add --region 1 --zone 1 --ip 192.168.100.10 --port 6002 --device sdb1 --weight 100

2.验证ring内容

# swift-ring-builder account.builder

3.平衡ring

# swift-ring-builder account.builder rebalance

2.创建ring容器

1.切换到 ``/etc/swift``目录。创建基本``container.builder``文件：

# cd /etc/swift

# swift-ring-builder container.builder create 10 1 1

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 sdc1 --weight 100

# swift-ring-builder container.builder add --region 1 --zone 1 --ip 192.168.100.20 --port 6001 --device sdd1 --weight 100

# swift-ring-builder container.builder add --region 1 --zone 1 --ip 192.168.100.10 --port 6001 --device sdc1 --weight 100

# swift-ring-builder container.builder add --region 1 --zone 1 --ip 192.168.100.10 --port 6001 --device sdb1 --weight 100

3.验证 ring 的内容：

# swift-ring-builder container.builder

4.平衡 ring：

# swift-ring-builder container.builder rebalance

3.创建Ring对象

1.切换到 ``/etc/swift``目录。创建基本``object.builder``文件：

# swift-ring-builder object.builder create 10 1 1

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 sdc1 --weight 100

# swift-ring-builder object.builder add --region 1 --zone 1 --ip 192.168.100.20 --port 6000 --device sdd1 --weight 100

# swift-ring-builder object.builder add --region 1 --zone 1 --ip 192.168.100.10 --port 6000 --device sdc1 --weight 100

# swift-ring-builder object.builder add --region 1 --zone 1 --ip 192.168.100.10 --port 6000 --device sdb1 --weight 100

3.验证 ring 的内容：

# swift-ring-builder object.builder

4.平衡 ring：

# swift-ring-builder object.builder rebalance

4.Compute节点复制Controller的配置文件

复制``account.ring.gz``，container.ring.gz``和``object.ring.gz 文件到每个存储节点和其他运行了代理服务的额外节点的 /etc/swift 目录。

[root@compute ~]# scp controller:/etc/swift/*.ring.gz /etc/swift/

5.启动服务

#### 1.在控制节点``Controller``上，启动对象存储代理服务及其依赖服务，并将它们配置为随系统启动：

# systemctl start openstack-swift-proxy.service memcached.service

# systemctl enable openstack-swift-proxy.service memcached.service

2.在存储节点Controller 和 Compute 两个节点上，启动对象存储服务，并将其设置为随系统启动

两个节点均需操作

# systemctl start openstack-swift-account.service openstack-swift-account-auditor.service openstack-swift-account-reaper.service openstack-swift-account-replicator.service

# systemctl enable openstack-swift-account.service openstack-swift-account-auditor.service openstack-swift-account-reaper.service openstack-swift-account-replicator.service

# systemctl start openstack-swift-container.service openstack-swift-container-auditor.service openstack-swift-container-replicator.service openstack-swift-container-updater.service

# systemctl enable openstack-swift-container.service openstack-swift-container-auditor.service openstack-swift-container-replicator.service openstack-swift-container-updater.service

# systemctl start openstack-swift-object.service openstack-swift-object-auditor.service openstack-swift-object-replicator.service openstack-swift-object-updater.service

# systemctl enable openstack-swift-object.service openstack-swift-object-auditor.service openstack-swift-object-replicator.service openstack-swift-object-updater.service

6.Controller执行验证操作

#### 1.导入demo凭证

# . /root/admin-openrc

2. 显示服务状态：

# swift stat

3.创建容器 container1

# openstack container create container1

4.上传一个测试文件到container1容器

# openstack object create container1 /root/demo-openrc

5.列出container1容器里的所有文件

# openstack object list container1

6.从container1容器里下载一个测试文件

# openstack object save container1 /root/demo-openrc
