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

编辑文件 /etc/swift/proxy-server.conf,删除原有内容，直接添加如下内容

# vi /etc/swift/proxy-server.conf

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

1.编辑 /etc/swift/account-server.conf 文件，删除原有内容，直接添加以下内容
#vi /etc/swift/account-server.conf

[DEFAULT]
bind_ip = 192.168.100.10

3.编辑``/etc/swift/object-server.conf``文件，删除原有内容，直接添加以下内容：
# vi /etc/swift/object-server.conf

[DEFAULT]
bind_ip = 192.168.100.10
bind_port = 6000
user = swift
swift_dir = /etc/swift
devices = /swift
mount_check = false
[pipeline:main]
pipeline = healthcheck recon object-server
[app:object-server]
use = egg:swift#object
[filter:healthcheck]

recon_lock_path = /var/lock
[object-replicator]
[object-reconstructor]
[object-updater]
[object-auditor]

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/sdc1 /swift/sdc xfs noatime,nodiratime,nobarrier,logbufs=8 0 0
/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
read only       = false
write only      = no
list            = yes
incoming chmod  = 0644
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

name = Policy-0
default = yes
aliases = yellow, orange
[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
