OpenStack Swift源码安装
1、安装拓扑
2、准备环境（所有节点）
2.1 由于本次安装选择的Ubuntu Server 12.04，需要安装以下必需软件包：
apt-get install build-essential git python-dev python-setuptools python-pip libxml2-dev libxslt-dev memcached
2.2 为每个节点创建swift用户
useradd -mk /home/swift/ -s /bin/bash swift
passwd swift #为swift用户添加密码，在此我将其设为了swift
编辑/etc/sudoer文件，在文件末尾添加如下代码
swift ALL=(ALL) NOPASSWD:ALL
3、Auth节点的安装（详见《Keystone源码安装文档》）
4、Storage和Proxy节点安装（所有节点）
4.1、源码安装
su swift #切换到swift用户
Mkdir -p /home/swift/openstack #创建一个目录来存放
cd /home/swift/openstack
git clone https://github.com/openstack/swift.git #下载swift
git clone https://github.com/openstack/keystone.git
cd swift; pip install -r tools/pip-requires; python setup.py install
cd keystone; pip install -r tools/pip-requires; python setup.py install
4.2 简单配置
1、将Swift源码目录的etc/下所有文件复制到/etc/keystone中，依次执行以下命令：
Mkdir -p /etc/swift
chown -R swift:swift /etc/swift
cp -r /home/swift/openstack/swift/etc/* /etc/swift
cd /etc/swift
mv proxy-server.conf-sample proxy-server.conf
mv account-server.conf-sample account-server.conf
mv memcache.conf-sample memcache.conf
mv container-server.conf-sample container-server.conf
mv object-server.conf-sample object-server.conf
mv rsyncd.conf-sample rsyncd.conf
mv swift.conf-sample swift.conf
2、修改swift.conf
首先生成随机数: md5sum swift.conf
221d17a3ddbec73528400a12d6d29fe6 swift.conf
将swift.conf中swift_hash_path_suffix的值用得到的随机数替换。
swift_hash_path_suffix = 221d17a3ddbec73528400a12d6d29fe6
3、修改rsyncd.conf
uid = swift
gid = swift
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
address = 127.0.0.1
[account]
max connections = 2
path = /srv/node
read only = false
lock file = /var/lock/account.lock
[container]
max connections = 4
path = /srv/node
read only = false
1lock file = /var/lock/container.lock
[object]
max connections = 8
path = /srv/node
read only = false
lock file = /var/lock/object.lock
将rsyncd.conf拷贝到/etc目录下：
Mv rsyncd.conf ../
修改/etc/default/rsync，将RSYNC_ENABLE的值设为true，RSYNC_ENABLE=true。
service rsync restart #最后重启rsync
4、修改proxy-server.conf
[DEFAULT]
bind_ip = 192.168.0.115 #proxy节点的ip，根据需要修改
bind_port = 8888
bind_timeout = 30
backlog = 4096
swift_dir = /etc/swift
workers = 2
user = swift
[pipeline:main]
pipeline = authtoken keystoneauth proxy-server
[app:proxy-server]
use = egg:swift#proxy
allow_account_management = true
account_autocreate = true
[filter:authtoken]
paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory
auth_host = 192.168.0.114 #keystone服务器的ip
auth_port = 35357
auth_protocol = http
auth_uri = http://192.168.0.114:5000/
admin_tenant_name = service
admin_user = swift
admin_password = openstack
admin_token = anytime
delay_auth_decision = 10
signing_dir=/etc/swift/signing_dir
[filter:keystoneauth]
paste.filter_factory = keystone.middleware.swift_auth:filter_factory
operator_roles = admin, swiftoperator
5、修改memcached.conf
[memcache]
memcache_servers = 192.168.0.115:11211
memcache_serialization_support = 2
6、修改account-server.conf
[DEFAULT]
bind_ip = 192.168.0.115 #其他节点修改为相应的ip
bind_port = 6012
bind_timeout = 30
backlog = 4096
workers = 2
user = swift
swift_dir = /etc/swift
devices = /srv/node
[pipeline:main]
pipeline = healthcheck recon account-server
[app:account-server]
use = egg:swift#account
[filter:healthcheck]
use = egg:swift#healthcheck
[filter:recon]
use = egg:swift#recon
recon_cache_path = /var/cache/swift
7、修改container-server.conf
[DEFAULT]
bind_ip = 192.168.0.115 #其他节点修改为相应的ip
bind_port = 6011
bind_timeout = 30
backlog = 4096
workers = 2
user = swift
swift_dir = /etc/swift
devices = /srv/node
[pipeline:main]
pipeline = healthcheck recon container-server
[app:account-server]
use = egg:swift#container
[filter:healthcheck]
use = egg:swift#healthcheck
[filter:recon]
use = egg:swift#recon
recon_cache_path = /var/cache/swift
8、修改object-server.conf
[DEFAULT]
bind_ip = 192.168.0.115 #其他节点修改为相应的ip
bind_port = 6010
bind_timeout = 30
backlog = 4096
workers = 2
user = swift
swift_dir = /etc/swift
devices = /srv/node
[pipeline:main]
pipeline = healthcheck recon object-server
[app:account-server]
use = egg:swift#object
[filter:healthcheck]
use = egg:swift#healthcheck
[filter:recon]
use = egg:swift#recon
recon_cache_path = /var/cache/swift
9、设置存储点
新增一个独立的未使用的分区作为存储点，/dev/sdb1。
mkdir -p /srv/node/sdb1
mkfs.xfs -i size=1024 /dev/sdb1 #以xfs方式格式化分区
chmod a+w /etc/fstab
echo “/dev/sdb1 /srv/node/sdb1 xfs noatime,nodiratime,nobarrier,logbufs=8 0 0” >> /etc/fstab
mount /srv/node/sdb1
chown -R swift:swift /srv/node/sdb1
chmod a+w -R /srv/node/sdb1
10、配置节点信息
生成ring文件，
cd /etc/swift
swift-ring-builder account.builder create 18 1 1
swift-ring-builder container.builder create 18 1 1
swift-ring-builder object.builder create 18 1 1
在ring基础上生成zone，在这里仅以一个节点为例，
swift-ring-builder account.builder add z1-192.168.0.115:6012/sdb1 100
swift-ring-builder container.builder add z1-192.168.0.115:6011/sdb1 100
swift-ring-builder object.builder add z1-192.168.0.115:6010/sdb1 100
验证ring文件的正确性，
swift-ring-builder account.builder
swift-ring-builder container.builder
swift-ring-builder object.builder
生成最终的ring，
swift-ring-builder account.builder rebalance
swift-ring-builder container.builder rebalance
swift-ring-builder object.builder rebalance
11、其他存储节点的配置
其他存储节点的配置和上面的步骤基本一致，但是在配置多存储节点时，需要注意第十步zone的生成，如果是配置两个节点，如下，更多的节点以此类推。
swift-ring-builder account.builder add z1-192.168.0.115:6012/sdb1 100
swift-ring-builder container.builder add z1-192.168.0.115:6011/sdb1 100
swift-ring-builder object.builder add z1-192.168.0.115:6010/sdb1 100
swift-ring-builder account.builder add z1-192.168.0.116:6012/sdb1 100
swift-ring-builder container.builder add z1-192.168.0.116:6011/sdb1 100
swift-ring-builder object.builder add z1-192.168.0.116:6010/sdb1 100
12、安装后的验证
swift-init all start
swift -V 2 -A http://192.168.0.114:5000/v2.0 -U adminTenant:admin -K openstack stat
