4.9 对象存储服务配置（Object Storage Service Swift）
通过REST API 提供对象存储和检索服务。
部署节点：Controller Node
openstack user create --domain default --password-prompt swift
openstack role add --project service --user swift admin
openstack service create --name swift   --description "OpenStack Object Storage" object-store
openstack endpoint create --region RegionOne   object-store public http://controller:8080/v1/AUTH_%\(tenant_id\)s
openstack endpoint create --region RegionOne   object-store admin http://controller:8080/v1

yum install openstack-swift-proxy python-swiftclient   python-keystoneclient python-keystonemiddleware   memcached
从对象存储软件源仓库下载对象存储代理服务配置文件
curl -o /etc/swift/proxy-server.conf https://git.openstack.org/cgit/o ... ple?h=stable/mitaka
修改配置文件sudo vi /etc/swift/proxy‐server.conf 。
[DEFAULT]
...
bind_port = 8080
user = swift
swift_dir = /etc/swift
在[pipeline:main] 处移除tempurl 和tempauth 模块，并添加authtoken 和keystoneauth 模块
[pipeline:main]
pipeline = catch_errors gatekeeper healthcheck proxy-logging cache container_sync bulk ratelimit authtoken keystoneauth container-quotas account-quotas slo dlo versioned_writes proxy-logging proxy-server
[app:proxy-server]
use = egg:swift#proxy
account_autocreate = True
[filter:keystoneauth]
use = egg:swift#keystoneauth
operator_roles = admin,user
[filter:authtoken]
paste.filter_factory = keystonemiddleware.auth_token:filter_factory
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = swift
password = SWIFT_PASS
delay_auth_decision = True
[filter:cache]
use = egg:swift#memcache
...
memcache_servers = controller:11211


部署节点：ObjectStorage Node
注：每个对象存储节点都需执行以下步骤

yum install xfsprogs rsync -y

# mkfs.xfs /dev/sdb
# mkfs.xfs /dev/sdc
# mkdir -p /srv/node/sdb
# mkdir -p /srv/node/sdc
/dev/sdb /srv/node/sdb xfs noatime,nodiratime,nobarrier,logbufs=8 0 2
/dev/sdc /srv/node/sdc xfs noatime,nodiratime,nobarrier,logbufs=8 0 2
# mount /srv/node/sdb
# mount /srv/node/sdc
vim  /etc/rsyncd.conf
uid = swift
gid = swift
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
address = MANAGEMENT_INTERFACE_IP_ADDRESS
[account]
max connections = 2
path = /srv/node/
read only = False
lock file = /var/lock/account.lock
[container]
max connections = 2
path = /srv/node/
read only = False
lock file = /var/lock/container.lock
[object]
max connections = 2
path = /srv/node/
read only = False
lock file = /var/lock/object.lock

# systemctl enable rsyncd.service
# systemctl start rsyncd.service


yum install openstack-swift-account openstack-swift-container  openstack-swift-object

curl -o /etc/swift/account-server.conf https://git.openstack.org/cgit/o ... ple?h=stable/mitaka
curl -o /etc/swift/container-server.conf https://git.openstack.org/cgit/o ... ple?h=stable/mitaka
curl -o /etc/swift/object-server.conf https://git.openstack.org/cgit/o ... ple?h=stable/mitaka
修改配置文件sudo vi /etc/swift/account‐server.conf 。
在[DEFAULT] 处配置绑定IP地址、绑定端口、用户、目录和挂载点：
注：将下面MANAGEMENT_INTERFACE_IP_ADDRESS 替换为对象存储节点Management Network 网络接口地
址10.0.0.51 或10.0.0.52
[DEFAULT]
bind_ip = MANAGEMENT_INTERFACE_IP_ADDRESS
bind_port = 6002
user = swift
swift_dir = /etc/swift
devices = /srv/node
mount_check = True
[pipeline:main]
pipeline = healthcheck recon account‐server
[filter:recon]
use = egg:swift#recon
recon_cache_path = /var/cache/swift
修改配置文件sudo vi /etc/swift/container‐server.conf
在[DEFAULT] 处配置绑定IP地址、绑定端口、用户、目录和挂载点：
注：将下面MANAGEMENT_INTERFACE_IP_ADDRESS 替换为对象存储节点Management Network 网络接口地
址10.0.0.51 或10.0.0.52
[DEFAULT]
bind_ip = MANAGEMENT_INTERFACE_IP_ADDRESS
bind_port = 6001
user = swift
swift_dir = /etc/swift
devices = /srv/node
mount_check = True
[pipeline:main]
pipeline = healthcheck recon container‐server
[filter:recon]
use = egg:swift#recon
recon_cache_path = /var/cache/swift
修改配置文件sudo vi /etc/swift/object‐server.conf
在[DEFAULT] 处配置绑定IP地址、绑定端口、用户、目录和挂载点：
注：将下面MANAGEMENT_INTERFACE_IP_ADDRESS 替换为对象存储节点Management Network 网络接口地
址10.0.0.51 或10.0.0.52
[DEFAULT]
bind_ip = MANAGEMENT_INTERFACE_IP_ADDRESS
bind_port = 6000
user = swift
swift_dir = /etc/swift
devices = /srv/node
mount_check = True
[pipeline:main]
pipeline = healthcheck recon object‐server
[filter:recon]
use = egg:swift#recon
recon_cache_path = /var/cache/swift
recon_lock_path = /var/lock

chown -R swift:swift /srv/node
mkdir -p /var/cache/swift
chown -R root:swift /var/cache/swift
chmod -R 775 /var/cache/swift
部署节点：Controller Node
创建和分发初始环
cd /etc/swift
创建基础的account.builder 文件：
[iyunv@controller swift]# swift-ring-builder account.builder create 10 3 1
将每个对象存储节点设备添加到账户环：
swift-ring-builder account.builder  add --region 1 --zone 1 --ip STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS --port 6002  --device DEVICE_NAME --weight DEVICE_WEIGHT
注：将STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS 替换为对象存储节点Management Network 网络接
口地址，将DEVICE_NAME 替换为对应的对象存储节点上的存储设备名称，将DEVICE_WEIGHT 替换为实际权重
值。
注：重复以上命令，将每个存储节点上的每个存储设备添加到账户环。
例如，本文采用如下命令将每个存储节点上的每个存储设备添加到账户环：
swift-ring-builder  account.builder add --region 1 --zone 1 --ip 10.0.0.51  --port 6002 --device sdb --weight 100
swift-ring-builder  account.builder add --region 1 --zone 1 --ip 10.0.0.51  --port 6002 --device sdc --weight 100
swift-ring-builder  account.builder add --region 1 --zone 2 --ip 10.0.0.52  --port 6002 --device sdb --weight 100
swift-ring-builder  account.builder add --region 1 --zone 2 --ip 10.0.0.52  --port 6002 --device sdc --weight 100
验证
swift-ring-builder account.builder
平衡账户环：
[iyunv@controller swift]# swift-ring-builder account.builder rebalance
Reassigned 3072 (300.00%) partitions. Balance is now 0.00.  Dispersion is now 0.00

swift-ring-builder container.builder create 10 3 1
swift-ring-builder  container.builder add --region 1 --zone 1 --ip 10.0.0.51  --port 6001 --device sdb --weight 100
swift-ring-builder  container.builder add --region 1 --zone 1 --ip 10.0.0.51  --port 6001 --device sdc --weight 100
swift-ring-builder  container.builder add --region 1 --zone 2 --ip 10.0.0.52  --port 6001 --device sdb --weight 100
swift-ring-builder  container.builder add --region 1 --zone 2 --ip 10.0.0.52  --port 6001 --device sdc --weight 100
swift-ring-builder container.builder
swift-ring-builder container.builder rebalance


swift-ring-builder object.builder create 10 3 1
swift-ring-builder  object.builder add --region 1 --zone 1 --ip 10.0.0.51  --port 6000 --device sdb --weight 100
swift-ring-builder  object.builder add --region 1 --zone 1 --ip 10.0.0.51  --port 6000 --device sdc --weight 100
swift-ring-builder  object.builder add --region 1 --zone 2 --ip 10.0.0.52  --port 6000 --device sdb --weight 100
swift-ring-builder  object.builder add --region 1 --zone 2 --ip 10.0.0.52  --port 6000 --device sdc --weight 100
swift-ring-builder object.builder
swift-ring-builder object.builder rebalance


分发环配置文件
将环配置文件account.ring.gz 、container.ring.gz 和object.ring.gz 拷贝到每个对象存储节点以及代理
服务节点的/etc/swift 目录。在每个存储节点或代理服务节点执行以下命令：
scp root@controller:/etc/swift/*.ring.gz /etc/swift   
本文将swift‐proxy 部署到controller节点，因此无需再讲环配置文件拷贝到代理服务节点的/etc/swift
目录。若对象存储代理服务swift‐proxy 部署在其他节点，则需将环配置文件拷贝到该代理服务节
点/etc/swift 目录下。
添加、分发swift 配置文件
① 从对象存储软件源仓库下载配置文件/etc/swift/swift.conf
curl -o /etc/swift/swift.conf  https://git.openstack.org/cgit/o ... ple?h=stable/mitaka
② 修改配置文件sudo vi /etc/swift/swift.conf
在[swift‐hash] 处哈希路径前缀和后缀
注：将HASH_PATH_PREFIX 和HASH_PATH_SUFFIX 替换为前面设计的唯一值。
[swift-hash]
...
swift_hash_path_suffix = HASH_PATH_SUFFIX
swift_hash_path_prefix = HASH_PATH_PREFIX
[storage‐policy:0]
name = Policy‐0
default = yes
③ 分发swift 配置文件
将/etc/swift/swift.conf 拷贝到每个对象存储节点以及代理服务节点的/etc/swift 目录。在每个存储节点
或代理服务节点执行以下命令：
scp root@controller:/etc/swift/swift.conf /etc/swift
④ 在所有存储节点和代理服务节点上设置swift配置目录所有权
chown  -R root:swift /etc/swift
在Controller节点和其他Swift代理服务节点上执行
systemctl enable openstack-swift-proxy.service memcached.service
systemctl start openstack-swift-proxy.service memcached.service
在所有对象存储节点上执行
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-account.service openstack-swift-account-auditor.service openstack-swift-account-reaper.service openstack-swift-account-replicator.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-container.service openstack-swift-container-auditor.service openstack-swift-container-replicator.service  openstack-swift-container-updater.service
systemctl enable openstack-swift-object.service openstack-swift-object-auditor.service openstack-swift-object-replicator.service openstack-swift-object-updater.service
systemctl start openstack-swift-object.service openstack-swift-object-auditor.service openstack-swift-object-replicator.service openstack-swift-object-updater.service
