openstack swift節點安裝手冊1-節點配置

本文參照官方教程：http://docs.openstack.org/project-install-guide/object-storage/draft/environment-networking.html

咱們要設置的swift節點名稱爲object1，主控節點和proxy節點都是controller。

在controller節點的/etc/hosts文件裏寫上節點名稱和ip地址，必須是能ping通的地址，同理，swift節點的/etc/hosts文件要寫上各類地址。

在controller節點上進行如下操做：

source /root/admin-openrc.sh #必須找到該配置文件

建立swift用戶：

openstack user create --domain default --password-prompt swift

給swift用戶賦予admin角色權限

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

建立swift服務：

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

建立endpoints：

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

安裝須要的組件：

yum install openstack-swift-proxy python-swiftclient python-keystoneclient python-keystonemiddleware memcached

下載配置文件：

curl -o /etc/swift/proxy-server.conf https://git.openstack.org/cgit/openstack/swift/plain/etc/proxy-server.conf-sample?h=stable/newton

修改配置文件/etc/swift/proxy-server.conf：

[DEFAULT]
bind_port = 8080
user = swift
swift_dir = /etc/swift

[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  #這裏有時候須要改爲127.0.0.1:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = swift
password = 要設置的swift用戶的密碼
delay_auth_decision = True

[filter:cache]
use = egg:swift#memcache
...
memcache_servers = controller:11211   #這裏有時候須要改爲127.0.0.1:11211

接下來在storage節點上操做，也就是swift節點，若節點機器有多個，須要在每臺節點機器上都執行
安裝依賴組件：

yum install xfsprogs rsync

預先鏈接幾塊未格式化的硬盤，不要掛載和格式化，而後執行如下命令，通常爲兩塊到三塊

mkfs.xfs /dev/sdb
mkfs.xfs /dev/sdc
mkfs.xfs /dev/sdd

建立對應的掛載節點目錄：

mkdir -p /srv/node/sdb
mkdir -p /srv/node/sdc
mkdir -p /srv/node/sdd

修改如下文件/etc/fstab：

/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
/dev/sdd /srv/node/sdd xfs noatime,nodiratime,nobarrier,logbufs=8 0 2

掛載盤：

mount /srv/node/sdb
mount /srv/node/sdc
mount /srv/node/sdd

修改/etc/rsyncd.conf文件：

uid = swift
gid = swift
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
address = storage節點用來與外部訪問的地址
[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

建立並重啓服務：

systemctl enable rsyncd.service systemctl start rsyncd.service

以上是針對proxy鏈接組件的安裝配置，接下來是account組件的配置，先安裝組件包：

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

修改/etc/swift/account-server.conf文件：

[DEFAULT]
...
bind_ip = storage（swift）節點用於外部訪問的鏈接地址
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container的配置文件/etc/swift/container-server.conf：

[DEFAULT]
...
bind_ip =storage（swift）節點用於外部訪問的鏈接地址
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object配置文件/etc/swift/object-server.conf：

[DEFAULT]
...
bind_ip =storage（swift）節點用於外部訪問的鏈接地址
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

給節點賦予權限

chown -R swift:swift /srv/node
mkdir -p /var/cache/swift
chown -R root:swift /var/cache/swift
chmod -R 775 /var/cache/swift
