openstack之对象存储服务SWIFT

一、在CONTROLLER机器上安装的配置

1、准备工作

[root@controller~]# .admin-openrc

2、创建认证服务凭证

[root@controller~]# openstackusercreate--domaindefault--password-promptswift（密码：

swift）

[root@controller~]#openstackroleadd--projectservice--userswiftadmin

[root@controller~]#openstackservicecreate--nameswift--description"OpenStackObjectStorage"object-store

3、创建对象存储服务的API

[root@controller~]#openstackendpointcreate--regionRegionOneobject-storepublic http:

//controller:

8080/v1/AUTH_%\（tenant_id\）s

[root@controller~]#openstackendpointcreate--regionRegionOneobject-storeinternal http:

//controller:

8080/v1/AUTH_%\（tenant_id\）s

root@controller~]#openstackendpointcreate--regionRegionOneobject-storeadmin http:

//controller:

8080/v1

4、安装配置组件

安装软件包

[root@controller~]#yuminstallopenstack-swift-proxypython-swiftclientpython-keystoneclientpython-keystonemiddlewarememcached

从对象存储库获取代理服务配置文件

[root@controller~]#curl-o/etc/swift/proxy-server.confhttps:

//git.openstack.org/cgit/openstack/swift/plain/etc/proxy-server.conf-sample?

h=stable/mitaka

编辑/etc/swift/proxy-server.conf

二、在存储节点上安装与配置（实验选择在COMPUTER机器上执行,增加两个磁盘）

1、准备

[root@computer~]#yuminstallxfsprogsrsync

[root@computer~]#mkfs.xfs/dev/sdc

[root@computer~]#mkfs.xfs/dev/sdd

[root@computer~]#mkdir-p/srv/node/sdc

[root@computer~]#mkdir-p/srv/node/sdd

编辑/etc/fstab文件

/dev/sdd/srv/node/sddxfsnoatime,nodiratime,nobarrier,logbufs=802

/dev/sdc/srv/node/sdcxfsnoatime,nodiratime,nobarrier,logbufs=802

[root@computer~]#mount/srv/node/sdc

[root@computer~]#mount/srv/node/sdd

创建或编辑/etc/rsyncd.conf文件 

uid=swift

gid=swift

logfile=/var/log/rsyncd.log

pidfile=/var/run/rsyncd.pid

address=10.1.42.212

[account]

maxconnections=2

path=/srv/node/

readonly=False

lockfile=/var/lock/account.lock

[container]

maxconnections=2

path=/srv/node/

readonly=False

lockfile=/var/lock/container.lock

[object]

maxconnections=2

path=/srv/node/

readonly=False

lockfile=/var/lock/object.loc

[root@computer~]#systemctlenablersyncd.service

[root@computer~]#systemctlstartrsyncd.service

2、安装配置组件

安装组件包

[root@computer~]#yuminstallopenstack-swift-accountopenstack-swift-containeropenstack-swift-object

获取accounting,container,andobjectservice的配置文件

 [root@computer~]#curl-o/etc/swift/account-server.confhttps:

//git.openstack.org/cgit/openstack/swift/plain/etc/account-server.conf-sample?

h=stable/mitaka

[root@computer~]#curl-o/etc/swift/container-server.confhttps:

//git.openstack.org/cgit/openstack/swift/plain/etc/container-server.conf-sample?

h=stable/mitaka

[root@computer~]#curl-o/etc/swift/object-server.confhttps:

//git.openstack.org/cgit/openstack/swift/plain/etc/object-server.conf-sample?

h=stable/mitaka

编辑/etc/swift/account-server.conf

[DEFAULT]

...

bind_ip=10.1.42.212

bind_port=6002

user=swift

swift_dir=/etc/swift

devices=/srv/node

mount_check=True

[pipeline:

编辑/etc/swift/object-server.conf 

[DEFAULT]

...

bind_ip=10.1.42.212

bind_port=6000

user=swift

swift_dir=/etc/swift

devices=/srv/node

mount_check=True

[pipeline:

pipeline=healthcheckreconobject-server

[filter:

recon]

use=egg:

...

recon_cache_path=/var/cache/swift

recon_lock_path=/var/lock

[root@computer~]#chown-Rswift:

[root@computer~]#mkdir-p/var/cache/swift

[root@computer~]#chown-Rroot:

swift/var/cache/swift

[root@computer~]#chmod-R775/var/cache/swift

三、在另一存储节点上安装与配置（实验选择在CONTROLLER机器上执行,增加两个磁盘）

重复执行第二步骤。

四、创建及分发初始环（在CONTROLLER机器上执行）

1、创建帐户环

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

创建account.builder文件

[root@controllerswift]#swift-ring-builderaccount.buildercreate1031

添加每个存储节点到环

[root@controllerswift]#swift-ring-builderaccount.builderadd--region1--zone1--ip10.1.42.211--port6002--devicesdb--weight100

Deviced0r1z1-10.1.42.211:

6002R10.1.42.211:

6002/sdb_""with100.0weightgotid0

[root@controllerswift]#swift-ring-builderaccount.builderadd--region1--zone1--ip10.1.42.211--port6002--devicesdc--weight100

Deviced1r1z1-10.1.42.211:

6002R10.1.42.211:

6002/sdc_""with100.0weightgotid1

[root@controllerswift]#swift-ring-builderaccount.builderadd--region1--zone1--ip10.1.42.212--port6002--devicesdc--weight100

Deviced2r1z1-10.1.42.212:

6002R10.1.42.212:

6002/sdc_""with100.0weightgotid2

[root@controllerswift]#swift-ring-builderaccount.builderadd--region1--zone1--ip10.1.42.212--port6002--devicesdd--weight100

Deviced3r1z1-10.1.42.212:

6002R10.1.42.212:

6002/sdd_""with100.0weightgotid3

较验环的内容

[root@controllerswift]#swift-ring-builderaccount.builder

重新平衡

[root@controllerswift]#swift-ring-builderaccount.builderrebalance

Reassigned3072（300.00%）partitions.Balanceisnow0.00. Dispersionisnow0.00

2、创建容器环

[root@controllerswift]#cd/etc/swift

创建container.builder文件

[root@controllerswift]#swift-ring-buildercontainer.buildercreate1031

添加每个存储节点到环

[root@controllerswift]#swift-ring-buildercontainer.builderadd --region1--zone1--ip10.1.42.211--port6001--devicesdb--weight100

Deviced0r1z1-10.1.42.211:

6001R10.1.42.211:

6001/sdb_""with100.0weightgotid0

[root@controllerswift]#swift-ring-buildercontainer.builderadd --region1--zone1--ip10.1.42.211--port6001--devicesdc--weight100

Deviced1r1z1-10.1.42.211:

6001R10.1.42.211:

6001/sdc_""with100.0weightgotid1

[root@controllerswift]#swift-ring-buildercontainer.builderadd --region1--zone1--ip10.1.42.212--port6001--devicesdc--weight100

Deviced2r1z1-10.1.42.212:

6001R10.1.42.212:

6001/sdc_""with100.0weightgotid2

[root@controllerswift]#swift-ring-buildercontainer.builderadd --region1--zone1--ip10.1.42.212--port6001--devicesdd--weight100

Deviced3r1z1-10.1.42.212:

6001R10.1.42.212:

6001/sdd_""with100.0weightgotid3

较验环的内容

[root@controllerswift]#swift-ring-buildercontainer.builder 

重新平衡（执行后就自动创建上图红圈的文件）

[root@controllerswift]#swift-ring-buildercontainer.builderrebalance

Reassigned3072（300.00%）partitions.Balanceisnow0.00. Dispersionisnow0.00

3、创建对象环

[root@controllerswift]#cd/etc/swift

创建object.builder 文件

[root@controllerswift]# swift-ring-builderobject.buildercreate1031

添加每个存储节点到环

[root@controllerswift]#swift-ring-builderobject.builderadd--region1--zone1--ip10.1.42.211--port6000--devicesdb--weight100

Deviced0r1z1-10.1.42.211:

6000R10.1.42.211:

6000/sdb_""with100.0weightgotid0

[root@controllerswift]#swift-ring-builderobject.builderadd--region1--zone1--ip10.1.42.211--port6000--devicesdc--weight100

Deviced1r1z1-10.1.42.211:

6000R10.1.42.211:

6000/sdc_""with100.0weightgotid1

[root@controllerswift]#swift-ring-builderobject.builderadd--region1--zone1--ip10.1.42.212--port6000--devicesdc--weight100

Deviced2r1z1-10.1.42.212:

6000R10.1.42.212:

6000/sdc_""with100.0weightgotid2

[root@controllerswift]#swift-ring-builderobject.builderadd--region1--zone1--ip10.1.42.212--port6000--devicesdd--weight100

Deviced3r1z1-10.1.42.212:

6000R10.1.42.212:

6000/sdd_""with100.0weightgotid3

较验环的内容

[root@controllerswift]#swift-ring-builderobject.builder

重新平衡

[root@controllerswift]#swift-ring-builderobject.builderrebalance

Reassigned3072（300.00%）partitions.Balanceisnow0.00. Dispersionisnow0.00

4、分发环配置文件

复制account.ring.gz,container.ring.gz,andobject.ring.gz三个文件到每个存储节点和代理服务节点的目录/etc/swift 

[root@controllerswift]#scp*.*.gzroot@10.1.42.212:

/etc/swift

五、最后安装

从对象存储源获取SWIFT.CONF

[root@controllerswift]#curl-o/etc/swift/swift.conf  https:

//git.openstack.org/cgit/openstack/swift/plain/etc/swift.conf-sample?

h=stable/mitaka

编辑/etc/swift/swift.conf

[swift-hash]

...

swift_hash_path_suffix=HASH_PATH_SUFFIX

swift_hash_path_prefix=HASH_PATH_PREFIX

[storage-policy:

0]

...

name=Policy-0

default=yes

复制 swift.conf文件到每个存储节点和代理服务节点的目录/etc/swift 

[root@controllerswift]#scpswift.confroot@10.1.42.212:

/etc/swift

在所有节点上执行

[root@controllerswift]#chown-Rroot:

swift/etc/swift

[root@computerswift]#chown-Rroot:

swift/etc/swift

在控制节点和其它节点上运行代理服务

[root@controllerswift]#systemctlenableopenstack-swift-proxy.servicememcached.service

[root@controllerswift]#systemctlstartopenstack-swift-proxy.servicememcached.service

在存储节点上运行ObjectStorageservices

[root@computerswift]#systemctlenableopenstack-swift-account.serviceopenstack-swif
