首先要感谢liu大神的翻译与试验,http://www.cnblogs.com/yuki-lau/
简介
本文详细描述使用单台服务器部署一个Swift开发版本的过程,单台服务器运行所有Swift服务,并模拟运行具有4个结点的Swift集群。其中,这里的“服务器”可以是物理机也可以是虚拟机。
已验证的部署环境:
- VMWare 7.1.2 Ubuntu-11.10-desktop-32位
- PC物理机 Ubuntu-11.10-desktop-64位
- PC物理机 Ubuntu-12.04-desktop-64位
版本说明
本文档基于:
- 官方文档:Swift 1.7.6-dev documentation
- Swift版本:1.7.6
- python-swiftclient版本:1.2.0
请确保安装的Swift版本和本文档中的版本相同。如有问题,请参考官网的更新文档。
1. 安装依赖包和核心代码
1. 以root身份登录。
# sudo su - root
2. 安装必须的依赖包、库。
# apt-get install python-software-properties
# add-apt-repository ppa:swift-core/release
# apt-get update
# apt-get install curl gcc git-core memcached python-coverage python-dev python-nose python-setuptools python-simplejson python-xattr sqlite3 xfsprogs python-eventlet python-greenlet python-pastedeploy python-netifaces python-pip
# pip install mock
3. 创建swift用户和组。在此,我们直接使用root作为用户名和组名。
接下来,需要选择使用一个分区作为存储(Using a partition for storage)或使用一个回环设备作为存储(Using a loopback device for storage),本文档使用回环设备作为存储。若希望使用一个单独的分区作为存储,请参阅这里。
2. 使用回环设备作为存储
1. 创建存储文件夹。
# mkdir /srv
2. 调整seek的值,可以创建一个更大或更小的分区。
# dd if=/dev/zero of=/srv/swift-disk bs=1024 count=0 seek=1000000
# mkfs.xfs -i size=1024 /srv/swift-disk
3. 编辑/etc/fstab并添加如下一行。
/srv/swift-disk /mnt/sdb1 xfs loop,noatime,nodiratime,nobarrier,logbufs=8 0 0
4. 创建挂载文件夹,并挂载。
# mkdir /mnt/sdb1
# mount /mnt/sdb1
5. 创建4个子节点文件夹。
# mkdir /mnt/sdb1/1 /mnt/sdb1/2 /mnt/sdb1/3 /mnt/sdb1/4
6. 改变权限,root:root对应<your-user-name>:<your-group-name>。
# chown root:root /mnt/sdb1/*
7. 为4个子节点创建同步链接。
# for x in {1..4}; do ln -s /mnt/sdb1/$x /srv/$x; done
8. 创建server等文件夹,并改编权限。注意,不要忘记/etc/swift /srv/[1-4]/最后一个“/”。
# mkdir -p /etc/swift/object-server /etc/swift/container-server /etc/swift/account-server /srv/1/node/sdb1 /srv/2/node/sdb2 /srv/3/node/sdb3 /srv/4/node/sdb4 /var/run/swift
# chown -R root:root /etc/swift /srv/[1-4]/ /var/run/swift
9. 编辑文件/etc/rc.local,在exit 0 之前添加如下4行。
# mkdir -p /var/cache/swift /var/cache/swift2 /var/cache/swift3 /var/cache/swift4
# chown root:root /var/cache/swift*
# mkdir -p /var/run/swift
# chown root:root /var/run/swift
3. 设置Rsync
1. 创建文件/etc/rsyncd.conf,内容如下:
uid = root
gid = root
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
address = 127.0.0.1
[account6012]
max connections = 25
path = /srv/1/node/
read only = false
lock file = /var/lock/account6012.lock
[account6022]
max connections = 25
path = /srv/2/node/
read only = false
lock file = /var/lock/account6022.lock
[account6032]
max connections = 25
path = /srv/3/node/
read only = false
lock file = /var/lock/account6032.lock
[account6042]
max connections = 25
path = /srv/4/node/
read only = false
lock file = /var/lock/account6042.lock
[container6011]
max connections = 25
path = /srv/1/node/
read only = false
lock file = /var/lock/container6011.lock
[container6021]
max connections = 25
path = /srv/2/node/
read only = false
lock file = /var/lock/container6021.lock
[container6031]
max connections = 25
path = /srv/3/node/
read only = false
lock file = /var/lock/container6031.lock
[container6041]
max connections = 25
path = /srv/4/node/
read only = false
lock file = /var/lock/container6041.lock
[object6010]
max connections = 25
path = /srv/1/node/
read only = false
lock file = /var/lock/object6010.lock
[object6020]
max connections = 25
path = /srv/2/node/
read only = false
lock file = /var/lock/object6020.lock
[object6030]
max connections = 25
path = /srv/3/node/
read only = false
lock file = /var/lock/object6030.lock
[object6040]
max connections = 25
path = /srv/4/node/
read only = false
lock file = /var/lock/object6040.lock
2. 编辑文件/etc/default/rsync,设置参数RSYNC_ENABLE为true。
RSYNC_ENABLE=true
3. 启动rsync服务
# service rsync restart
4. 设置独立日志(可选)
1. 创建文件/etc/rsyslog.d/10-swift.conf,内容如下:
# Uncomment the following to have a log containing all logs together
#local1,local2,local3,local4,local5.* /var/log/swift/all.log
# Uncomment the following to have hourly proxy logs for stats processing
#$template HourlyProxyLog,"/var/log/swift/hourly/%$YEAR%%$MONTH%%$DAY%%$HOUR%"
#local1.*;local1.!notice ?HourlyProxyLog
local1.*;local1.!notice /var/log/swift/proxy.log
local1.notice /var/log/swift/proxy.error
local1.* ~
local2.*;local2.!notice /var/log/swift/storage1.log
local2.notice /var/log/swift/storage1.error
local2.* ~
local3.*;local3.!notice /var/log/swift/storage2.log
local3.notice /var/log/swift/storage2.error
local3.* ~
local4.*;local4.!notice /var/log/swift/storage3.log
local4.notice /var/log/swift/storage3.error
local4.* ~
local5.*;local5.!notice /var/log/swift/storage4.log
local5.notice /var/log/swift/storage4.error
local5.* ~
2. 编辑文件/etc/rsyslog.conf,更改参数$PrivDropToGroup为adm。
$PrivDropToGroup adm
3. 创建swift每小时的文件夹。
# mkdir -p /var/log/swift/hourly
4. 更改swift的log文件夹权限。
# chown -R syslog.adm /var/log/swift
# chmod -R g+w /var/log/swift
5. 重启rsyslog服务。
# service rsyslog restart
5. 获取代码并设置测试环境
若不打算在全root权限下安装Swift,则需要切换回guest权限。此处,我们全部使用root安装。
1. 创建文件夹。
# mkdir ~/bin
2. 从git上获取swift代码,下载到本地。
# git clone https://github.com/openstack/swift.git
3. 安装Swift的开发版本。
# cd ~/swift
# python setup.py develop
# cd ..
4. 从git上获取python-swiftclient代码,下载到本地。
# git clone https://github.com/openstack/python-swiftclient.git
5. 安装python-swiftclient的开发版本。
# cd ~/python-swiftclient
# python setup.py develop
# cd ..
6. 编辑文件~/.bashrc,并在文件尾添加如下内容:

7. 创建Swift运行脚本
1. 创建脚本~/bin/resetswift,内容如下。注意,如果使用的是单独分区存储需要将/srv/swift-disk替换为/dev/sdb1;如果没有创建rsyslog作为独立日志,则需要移除find /var/log/swift... 这一行。
#!/bin/bash
swift-init all stop
find /var/log/swift -type f -exec rm -f {} \;
sudo umount /mnt/sdb1
sudo mkfs.xfs -f -i size=1024 /srv/swift-disk
sudo mount /mnt/sdb1
sudo mkdir /mnt/sdb1/1 /mnt/sdb1/2 /mnt/sdb1/3 /mnt/sdb1/4
sudo chown root:root /mnt/sdb1/*
mkdir -p /srv/1/node/sdb1 /srv/2/node/sdb2 /srv/3/node/sdb3 /srv/4/node/sdb4
sudo rm -f /var/log/debug /var/log/messages /var/log/rsyncd.log /var/log/syslog
find /var/cache/swift* -type f -name *.recon -exec rm -f {} \;
sudo service rsyslog restart
sudo service memcached restart
2. 创建脚本~/bin/remakerings,内容如下:
#!/bin/bash
cd /etc/swift
rm -f *.builder *.ring.gz backups/*.builder backups/*.ring.gz
swift-ring-builder object.builder create 18 3 1
swift-ring-builder object.builder add z1-127.0.0.1:6010/sdb1 1
swift-ring-builder object.builder add z2-127.0.0.1:6020/sdb2 1
swift-ring-builder object.builder add z3-127.0.0.1:6030/sdb3 1
swift-ring-builder object.builder add z4-127.0.0.1:6040/sdb4 1
swift-ring-builder object.builder rebalance
swift-ring-builder container.builder create 18 3 1
swift-ring-builder container.builder add z1-127.0.0.1:6011/sdb1 1
swift-ring-builder container.builder add z2-127.0.0.1:6021/sdb2 1
swift-ring-builder container.builder add z3-127.0.0.1:6031/sdb3 1
swift-ring-builder container.builder add z4-127.0.0.1:6041/sdb4 1

swift-ring-builder account.builder add z4-127.0.0.1:6042/sdb4 1
swift-ring-builder account.builder rebalance
3. 创建脚本~/bin/startmain,内容如下:
#!/bin/bash
swift-init main start
4. 创建脚本~/bin/startrest,内容如下:
#!/bin/bash
swift-init rest start
5. 更改脚本权限。
# chmod +x ~/bin/*
6. 创建rings。
# remakerings
7. 执行功能单元测试,出现“Unable to read test config /etc/swift/test.conf – file not found”,可不必理会,或手动复制过去(配置文件在swift/test/sample.conf)。
# cd ~/swift
# ./.unittests
8. 运行swift,出现“Unable to increase file descriptor limit. Running as non-root?”警告为正常现象,不必理会。
# startmain
8. 简单使用
完成安装部署后,可以使用swift --help命令查看Swift帮助信息。
# swift --help
Usage: swift <command> [options] [args]
Commands:
stat [container] [object]
Displays information for the account, container, or object depending on the
args given (if any).
list [options] [container]
Lists the containers for the account or the objects for a container. -p or
--prefix is an option that will only list items beginning with that prefix.
-d or --delimiter is option (for container listings only) that will roll up
items with the given delimiter (see Cloud Files general documentation for
what this means).
upload [options] container file_or_directory [file_or_directory] [...]
Uploads to the given container the files and directories specified by the
remaining args. -c or --changed is an option that will only upload files
that have changed since the last upload. -S <size> or --segment-size <size>
and --leave-segments are options as well (see --help for more).
post [options] [container] [object]
Updates meta information for the account, container, or object depending on
the args given. If the container is not found, it will be created
automatically; but this is not true for accounts and objects. Containers
also allow the -r (or --read-acl) and -w (or --write-acl) options. The -m
or --meta option is allowed on all and used to define the user meta data
items to set in the form Name:Value. This option can be repeated. Example:
post -m Color:Blue -m Size:Large
download --all OR download container [options] [object] [object] ...
Downloads everything in the account (with --all), or everything in a
container, or a list of objects depending on the args given. For a single
object download, you may use the -o [--output] <filename> option to
redirect the output to a specific file or if "-" then just redirect to
stdout.
delete [options] --all OR delete container [options] [object] [object] ...
Deletes everything in the account (with --all), or everything in a
container, or a list of objects depending on the args given. Segments of
manifest objects will be deleted as well, unless you specify the
--leave-segments option.
Example:
swift -A https://auth.api.rackspacecloud.com/v1.0 -U user -K key stat
Options:
--version show program‘s version number and exit
-h, --help show this help message and exit
-s, --snet Use SERVICENET internal network
-v, --verbose Print more info
-q, --quiet Suppress status output
-A AUTH, --auth=AUTH URL for obtaining an auth token
-V AUTH_VERSION, --auth-version=AUTH_VERSION
Specify a version for authentication. Defaults to 1.0.
-U USER, --user=USER User name for obtaining an auth token.
-K KEY, --key=KEY Key for obtaining an auth token.
--os-username=<auth-user-name>
Openstack username. Defaults to env[OS_USERNAME].
--os-password=<auth-password>
Openstack password. Defaults to env[OS_PASSWORD].
--os-tenant-id=<auth-tenant-id>
OpenStack tenant ID. Defaults to env[OS_TENANT_ID]

env[OS_ENDPOINT_TYPE]
--insecure Allow swiftclient to access insecure keystone server.
The keystone‘s certificate will not be verified.
1. 获取一个 X-Storage-Url 和 X-Auth-Token。
# curl -v -H ‘X-Storage-User: test:tester‘ -H ‘X-Storage-Pass: testing‘ http://127.0.0.1:8080/auth/v1.0
可以得到以下返回信息:
* About to connect() to 127.0.0.1 port 8080 (#0)
* Trying 127.0.0.1... connected
* Connected to 127.0.0.1 (127.0.0.1) port 8080 (#0)
> GET /auth/v1.0 HTTP/1.1
> User-Agent: curl/7.19.7 (i486-pc-linux-gnu) libcurl/7.19.7 OpenSSL/0.9.8k zlib/1.2.3.3 libidn/1.15
> Host: 127.0.0.1:8080
> Accept: */*
> X-Storage-User: test:tester
> X-Storage-Pass: testing
< HTTP/1.1 200 OK
< X-Storage-Url: http://127.0.0.1:8080/v1/AUTH_test
< X-Storage-Token: AUTH_tk6474e5ee0cb04832b9d2a168e1a164d8
< X-Auth-Token: AUTH_tk6474e5ee0cb04832b9d2a168e1a164d8
< Content-Length: 0
< Date: Mon, 04 Jul 2011 01:36:57 GMT
* Connection #0 to host 127.0.0.1 left intact
*Closing connection #0
2. 检查账户。注意,X-Auth-Token:与<token-from-x-auth-token-above>之间存在一个空格,一定不能丢。
# curl -v -H ‘X-Auth-Token: <token-from-x-auth-token-above>‘ <url-from-x-storage-url-above>
3. 检查Swift工作。
# swift -A http://127.0.0.1:8080/auth/v1.0 -U test:tester -K testing stat
正确情况下,应该输出以下信息:
Account: AUTH_test
Containers: 0
Objects: 0
Bytes: 0
Accept-Ranges: bytes
4. 创建container,创建一个名称为container_test的container(目录),注意使用当前的token。
# curl -X PUT -D - -H "X-Auth_Token:AUTH_tk6474e5ee0cb04832b9d2a168e1a164d8" http://127.0.0.1:8080/v1/AUTH_test/container_test
正确情况下,应该得到以下信息:
HTTP/1.1 201 Created
Content-Length: 0
Content-Type: text/html; charset=UTF-8
Date: Mon, 04 Jul 2011 01:39:38 GMT
5. 查看test用户的container列表,发现只有一个目录:container_test。
# swift -A http://127.0.0.1:8080/auth/v1.0 -U test:tester -K testing list
container_test
6. 上传Object(文件),上传hello文件到container_test目录中。
# swift -A http://127.0.0.1:8080/auth/v1.0 -U test:tester -K testing upload container_test /root/hello
root/hello
7. 查看目录中的内容,查看container_test目录中的内容。
# swift -A http://127.0.0.1:8080/auth/v1.0 -U test:tester -K testing list container_test
root/hello
8. 下载Object(文件)下载container_test下的object。
# swift -A http://127.0.0.1:8080/auth/v1.0 -U test:tester -K testing download container_test
将container_test目录内的所有内容下载到目前所在目录。注意:如果上传文件的时候,有嵌套目录,则上传到Swift上后,也是以嵌套目录的形式存在,下载后,会在当前目录创建一样的嵌套目录。
补充说明:
现在已经完成SAIO的部署了,下面介绍一下系统环境的改变:
1. ~/swift目录下存放Swift与python-swiftclient的源代码与执行脚本。
- ~/swift/bin目录下存放执行脚本。
- ~/swift/swift_1.7.6目录下存放Swift的源代码。
- ~/swift/python-swiftclient_1.2.0目录下存放Swift客户端的源代码。
2. /usr/local/lib/python2.7/dist-packages、/usr/share/pyshared、/usr/bin、/usr/local/bin等目录下存放Swift与python-swiftclient安装后的程序文件。
3. Swift的回环设备挂载在/mnt/sdb1目录上。
4. 回环设备对应的文件为/srv/swift-disk。
5. 四个存储节点对应的实际存储空间(即共享上述回环设备)——/mnt/sdb1/1、/mnt/sdb1/2、/mnt/sdb1/3、/mnt/sdb1/4。
6. 四个存储节点指向实际存储空间的软链接——/srv/1、/srv/2、/srv/3、/srv/4。
7. 四个存储节点的对应的虚拟挂载点——/srv/1/node/sdb1、/srv/2/node/sdb2、/srv/2/node/sdb2、/srv/2/node/sdb2。
8. Swift运行时所需目录/var/run/swift,用于存放各个服务进程的pid文件等内容。
9. Swift临时缓存的目录(姑且这么理解)——/var/cache/swift、/var/cache/swift2、/var/cache/swift3、/var/cache/swift4。
10. /etc/swift目录中存放Swift自身的配置文件。
- /etc/swift/object-server目录中存放四个存储节点的Object Server配置文件。
- /etc/swift/container-server目录中存放四个存储节点的Container Server配置文件。
- /etc/swift/account-server目录中存放四个存储节点的Account Server配置文件。
- /etc/swift/proxy-server.conf为Proxy Server的配置文件。
- /etc/swift/swift.conf为Swift哈希后缀的配置文件。
- backups目录、*.builder文件和*.ring.rz文件都是Ring的相关文件,其中*.ring.rz文件记录了生成的Ring。
- test.conf文件是Swift单元测试所需的文件。
11. /var/log/swift目录下存放rsyslog独立日志工具输出的日志文件。
12. 其他被创建的文件:
- /etc/rsyncd.conf,作为rsync数据镜像备份工具的配置文件。
- /etc/rsyslog.d/10-swift.conf,作为rsyslog独立日志工具的配置文件。
13. 其他被修改的文件:
- /etc/fstab,回环设备挂载相关配置文件。
- /etc/rc.local,使得系统在启动时自动创建一些Swift所需的目录,这些目录可能在系统关闭后丢失。
- /etc/default/rsync,使rsync能开机启动。
- /etc/rsyslog.conf,改变rsyslog工具所在的Group。
- ~/.bashrc,使新增的环境变量生效。
