openstack swift节点安装手册1-节点配置
本文参照官方教程：http://docs.openstack.org/project-install-guide/object-storage/draft/environment-networking.html我们要设置的swift节点名称为object1，主控节点和proxy节点都是controller。
在controller节点的/etc/hosts文件里写上节点名称和ip地址，必须是能ping通的地址，同理，swift节点的/etc/hosts文件要写上各种地址。
在controller节点上进行以下操作：
source /root/admin-openrc.sh #必须找到该配置文件
创建swift用户：
openstack user create --domain default --password-prompt swift
给swift用户赋予admin角色权限
openstack role add --project service --user swift admin
创建swift服务：
openstack service create --name swift --description "OpenStack Object Storage" object-store
创建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
安装需要的组件：
yum install openstack-swift-proxy python-swiftclient python-keystoneclient python-keystonemiddleware memcached
下载配置文件：
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：
bind_port = 8080
user = swift
swift_dir = /etc/swift
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
use = egg:swift#proxy
...
account_autocreate = True
use = egg:swift#keystoneauth
...
operator_roles = admin,user
paste.filter_factory = keystonemiddleware.auth_token:filter_factory
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211#这里有时候需要改成127.0.0.1:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = swift
password = 要设置的swift用户的密码
delay_auth_decision = True
use = egg:swift#memcache
...
memcache_servers = controller:11211 #这里有时候需要改成127.0.0.1:11211
接下来在storage节点上操作，也就是swift节点，若节点机器有多个，需要在每台节点机器上都执行
安装依赖组件：
yum install xfsprogs rsync
预先连接几块未格式化的硬盘，不要挂载和格式化，然后执行以下命令，一般为两块到三块
mkfs.xfs /dev/sdb
mkfs.xfs /dev/sdc
mkfs.xfs /dev/sdd
创建对应的挂载节点目录：
mkdir -p /srv/node/sdb
mkdir -p /srv/node/sdc
mkdir -p /srv/node/sdd
修改以下文件/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
挂载盘：
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节点用来与外部访问的地址
max connections = 2
path = /srv/node/
read only = False
lock file = /var/lock/account.lock
max connections = 2
path = /srv/node/
read only = False
lock file = /var/lock/container.lock
max connections = 2
path = /srv/node/
read only = False
lock file = /var/lock/object.lock
创建并重启服务：
systemctl enable rsyncd.service
systemctl start rsyncd.service
以上是针对proxy连接组件的安装配置，接下来是account组件的配置，先安装组件包：
yum install openstack-swift-account openstack-swift-container openstack-swift-object
修改/etc/swift/account-server.conf文件：
...
bind_ip = storage（swift）节点用于外部访问的连接地址
bind_port = 6002
user = swift
swift_dir = /etc/swift
devices = /srv/node
mount_check = True
pipeline = healthcheck recon account-server
use = egg:swift#recon
...
recon_cache_path = /var/cache/swift
修改container的配置文件/etc/swift/container-server.conf：
...
bind_ip =storage（swift）节点用于外部访问的连接地址
bind_port = 6001
user = swift
swift_dir = /etc/swift
devices = /srv/node
mount_check = True
pipeline = healthcheck recon container-server
use = egg:swift#recon
...
recon_cache_path = /var/cache/swift
修改object配置文件/etc/swift/object-server.conf：
...
bind_ip =storage（swift）节点用于外部访问的连接地址
bind_port = 6000
user = swift
swift_dir = /etc/swift
devices = /srv/node
mount_check = True
pipeline = healthcheck recon object-server
use = egg:swift#recon
...
recon_cache_path = /var/cache/swift
recon_lock_path = /var/lock
给节点赋予权限
chown -R swift:swift /srv/node
mkdir -p /var/cache/swift
chown -R root:swift /var/cache/swift
chmod -R 775 /var/cache/swift
