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
