1、安装配置swift存储节点
(1)安装swift软件
yum -y install openstack-utils openstack-swift-account openstack-swift-container openstack-swift-object xfsprogs python-keystone
(2)新建硬盘分区，这里其余2块分区一样的
fdisk /dev/sdb mkfs.xfs /dev/sdb1
(3)建立挂载目录，写进开机启动挂载
mkdir -pv /srv/node/sd{b,c,d}1
echo "/dev/sdb1 /srv/node/sdb1 xfs noatime,nodiratime,nobarrier,logbufs=8 0 0" >> /etc/fstab
echo "/dev/sdc1 /srv/node/sdc1 xfs noatime,nodiratime,nobarrier,logbufs=8 0 0" >> /etc/fstab
echo "/dev/sdd1 /srv/node/sdd1 xfs noatime,nodiratime,nobarrier,logbufs=8 0 0" >> /etc/fstab
(4)下载并修改/etc/swift/account-server.conf文件
curl -o /etc/swift/account-server.conf https://raw.githubusercontent.com/openstack/swift/stable/juno/etc/account-server.conf-sample
[DEFAULT] ... bind_ip = 10.90.2.100 bind_port = 6002 user = swift swift_dir = /etc/swift devices = /srv/node [pipeline:main] pipeline = healthcheck recon account-server [filter:recon] ... recon_cache_path = /var/cache/swift
(5)下载并修改/etc/swift/container-server.conf 文件
curl -o /etc/swift/container-server.conf https://raw.githubusercontent.com/openstack/swift/stable/juno/etc/container-server.conf-sample [DEFAULT] ... bind_ip = 10.90.2.100 bind_port = 6001 user = swift swift_dir = /etc/swift devices = /srv/node [pipeline:main] pipeline = healthcheck recon container-server [filter:recon] ... recon_cache_path = /var/cache/swift
(6)下载并修改/etc/swift/object-server.conf 文件
c
url -o /etc/swift/object-server.conf https://raw.githubusercontent.com/openstack/swift/stable/juno/etc/object-server.conf-sample [DEFAULT] ... bind_ip = 10.90.2.100 bind_port = 6000 user = swift swift_dir = /etc/swift devices = /srv/node [pipeline:main] pipeline = healthcheck recon object-server [filter:recon] ... recon_cache_path = /var/cache/swift
(7)建立目录添加权限
chown -R swift:swift /srv/node mkdir -p /var/cache/swift chown -R swift:swift /var/cache/swift
(8)创建所需ring，通过“swift-ring-builder”命令创建account、container和object所用的ring文件，注意要在/etc/swift目录下执行
cd /etc/swift swift-ring-builder account.builder create 10 3 1 swift-ring-builder container.builder create 10 3 1 swift-ring-builder object.builder create 10 3 1
上面的命令后面三个参数中，18表示构建一致hash环时其环的大小，即使用2^18大小的环。实际使用中，可以根据节点数规模进行调整，最大为32；3表示为每个对象存储3个副本；最后的1表示多长时间可以移动一次某partiton。
(9)将存储设备关系至ring
在ring文件创建完成后，还需要将每个存储设备添加至每个ring上，而且通常需要以account、container和object的顺序进行。其格式为：
swift-ring-builder account.builder add z<ZONE>-<STORAGE_LOCAL_NET_IP>:6002/<DEVICE> 100
swift-ring-builder container.builder add z<ZONE>-<STORAGE_LOCAL_NET_IP_1>:6001/<DEVICE> 100
swift-ring-builder object.builder add z<ZONE>-<STORAGE_LOCAL_NET_IP_1>:6000/<DEVICE> 100
其中<ZONE>为zone编号，如z1表示第一个zone；<STORAGE_LOCAL_NET_IP>表示存储节点自己的IP地址；<DEVICE>表示对应设备的设备名称或挂载点名称(二者通常相同)，如/dev/sdb1设备的挂载点为/srv/node/sdb1时，其<DEVICE>即为sdb1。因此，将sdb1、sdc1和sdd1三个设备添加至ring文件可通过如下命令实现。
swift-ring-builder account.builder add z1-10.90.2.100:6002/sdb1 100 swift-ring-builder container.builder add z1-10.90.2.100:6001/sdb1 100 swift-ring-builder object.builder add z1-10.90.2.100:6000/sdb1 100 swift-ring-builder account.builder add z2-10.90.2.100:6002/sdc1 100 swift-ring-builder container.builder add z2-10.90.2.100:6001/sdc1 100 swift-ring-builder object.builder add z2-10.90.2.100:6000/sdc1 100 swift-ring-builder account.builder add z3-10.90.2.100:6002/sdd1 100 swift-ring-builder container.builder add z3-10.90.2.100:6001/sdd1 100 swift-ring-builder object.builder add z3-10.90.2.100:6000/sdd1 100
(10)查看每个ring文件的内容，验正添加结果：
# swift-ring-builder account.builder account.builder, build version 3 262144 partitions, 3 replicas, 3 zones, 3 devices, 100.00 balance The minimum number of hours before a partition can be reassigned is 1 Devices: id zone ip address port name weight partitions balance meta 0 1 10.90.2.100 6002 sdb1 100.00 0 -100.00 1 2 10.90.2.100 6002 sdc1 100.00 0 -100.00 2 3 10.90.2.100 6002 sdd1 100.00 0 -100.00 # swift-ring-builder container.builder container.builder, build version 3 262144 partitions, 3 replicas, 3 zones, 3 devices, 100.00 balance The minimum number of hours before a partition can be reassigned is 1 Devices: id zone ip address port name weight partitions balance meta 0 1 10.90.2.100 6001 sdb1 100.00 0 -100.00 1 2 10.90.2.100 6001 sdc1 100.00 0 -100.00 2 3 10.90.2.100 6001 sdd1 100.00 0 -100.00 # swift-ring-builder object.builder object.builder, build version 3 262144 partitions, 3 replicas, 3 zones, 3 devices, 100.00 balance The minimum number of hours before a partition can be reassigned is 1 Devices: id zone ip address port name weight partitions balance meta 0 1 10.90.2.100 6000 sdb1 100.00 0 -100.00 1 2 10.90.2.100 6000 sdc1 100.00 0 -100.00 2 3 10.90.2.100 6000 sdd1 100.00 0 -100.00
(11)使用如下命令重新平衡三个环，即将对应的设备分布式环中的节点上。不过，执行这些命令可能会需要一些时间。
swift-ring-builder account.builder rebalance swift-ring-builder container.builder rebalance swift-ring-builder object.builder rebalance
(12)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 目录下
确保每个节点的/etc/swift目录及其内部子目录和文件的属主为swift用户，属组为swift组。
chown -R swift:swift /etc/swift
(13)配置hash和默认的存储策略
#curl -o /etc/swift/swift.conf https://raw.githubusercontent.com/openstack/swift/stable/juno/etc/swift.conf-sample #openssl rand -hex 10 89e49ff5a001520f4150 [swift-hash] ... swift_hash_path_suffix = 89e49ff5a001520f4150 swift_hash_path_prefix = 89e49ff5a001520f4150 [storage-policy:0] ... name = Policy-0 default = yes
(14)复制 swift.conf 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 目录下,在所有节点上，确认配置文件目录是否有合适的所有权：
scp /etc/swift/*.gz 10.90.2.1:/etc/swift ssh 10.90.2.1 "chown -R swift:swift"
(15)在存储节点上，启动对象存储服务，并将其设置为随系统启动：
systemctl enable 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 enable openstack-swift-object.service openstack-swift-object-auditor.service openstack-swift-object-replicator.service openstack-swift-object-updater.service systemctl status openstack-swift-account.service openstack-swift-account-auditor.service openstack-swift-account-reaper.service openstack-swift-account-replicator.service systemctl status openstack-swift-container.service openstack-swift-container-auditor.service openstack-swift-container-replicator.service openstack-swift-container-updater.service systemctl status openstack-swift-object.service openstack-swift-object-auditor.service openstack-swift-object-replicator.service openstack-swift-object-updater.service
2、安装配置proxy_swift代理节点,在控制节点
(1)安装proxy基本软件
yum -y install openstack-swift-proxy memcached python-keystone openstack-utils python-keystoneclient
(2)启动memcached服务,开机自起(这个如果控制节点装了就不需要在执行了)
systemctl start memcached systemctl enable memcached
(3)修改配置swift-proxy配置文件/etc/swift/proxy-server.conf
curl -o /etc/swift/proxy-server.conf https://raw.githubusercontent.com/openstack/swift/stable/juno/etc/proxy-server.conf-sample [DEFAULT] ... bind_port = 8080 user = swift swift_dir = /etc/swift [pipeline:main] pipeline = authtoken cache healthcheck proxy-logging proxy-server keystoneauth(注意这个keystoneauth有问题可以不需要填写) [app:proxy-server] ... allow_account_management = true account_autocreate = true [filter:keystoneauth] use = egg:swift#keystoneauth ... operator_roles = admin,_member_ [filter:cache] ... memcache_servers = 127.0.0.1:11211 [filter:authtoken] paste.filter_factory = keystonemiddleware.auth_token:filter_factory ... auth_host = 10.90.2.1 auth_port = 35357 auth_protocol = http auth_uri = http://10.90.2.1:5000/ admin_tenant_name = service admin_user = swift admin_password = Service
(4)在控制节点和其他运行了代理服务的节点上，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 enable openstack-swift-proxy.service systemctl start openstack-swift-proxy.service
(5)swift基本验证
# swift stat Account: AUTH_06536a37d6434cbb85834e6a1d9eb421 Containers: 0 Objects: 0 Bytes: 0 Containers in policy "policy-0": 0 Objects in policy "policy-0": 0 Bytes in policy "policy-0": 0 X-Account-Project-Domain-Id: default Connection: keep-alive X-Timestamp: 1445927026.21389 X-Trans-Id: txd6da3be6a251407f8f786-00562f275a Content-Type: text/plain; charset=utf-8 Accept-Ranges: bytes
(6)上传文件，查看
#swift upload testfile localfile #swift list testfile
(7)配置glance+swift，修改/etc/glance/glance-api.conf
[DEFAULT] default_store = swift swift_store_auth_address=http://10.90.2.1:5000/v2.0/ swift_store_create_container_on_put=True swift_store_user=service:swift swift_store_auth_version=2 swift_store_key=Service123 enable_v2_api=True …… [glance_store] stores=glance.store.swift.Store
(8)重新启动glance服务：
systemctl restart openstack-glance-api openstack-glance-registry # glance image-create --name "cirros-3.3.3-x86_64x1" --file cirros-0.3.3-x86_64-disk.img --disk-format qcow2 --container-format bare --is-public True --progress [=============================>] 100% +------------------+--------------------------------------+ | Property | Value | +------------------+--------------------------------------+ | checksum | 133eae9fb1c98f45894a4e60d8736619 | | container_format | bare | | created_at | 2015-11-26T02:17:17 | | deleted | False | | deleted_at | None | | disk_format | qcow2 | | id | a6185a87-8291-4053-9ac1-6fb6fe1997f6 | | is_public | True | | min_disk | 0 | | min_ram | 0 | | name | cirros-3.3.3-x86_64x1 | | owner | 5cd48f15e3514988870611ab2eeee536 | | protected | False | | size | 13200896 | | status | active | | updated_at | 2015-11-26T02:17:19 | | virtual_size | None | +------------------+--------------------------------------+
