OpenStack Swift源码安装

wangluo010

　　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
