使用Docker+Seafile搭建私有云存储

 

Docker和Seafile介绍

Docker是一个开源的应用容器引擎，让开发者可以打包他们的应用以及依赖包到一个可移植的容器中，然后发布到任何流行的Linux 机器上，也可以实现虚拟化。容器是完全使用沙箱机制，相互之间不会有任何接口（类似iPhone的 app）。几乎没有性能开销,可以很容易地在机器和数据中心中运行。最重要的是,他们不依赖于任何语言、框架或包装系统。

Docker能简化我们的云存储搭建过程，还能使其更安全地运行，更方便的维护。

Seafile是新一代的开源云存储软件。它提供更丰富的文件同步和管理功能，以及更好的数据隐私保护和群组协作功能。Seafile支持 Mac、Linux、Windows三个桌面平台，支持Android和iOS 两个移动平台。

Seafile是由国内团队开发的国际型项目，目前已有10万左右的用户，以欧洲用户为多。典型的机构用户包括比利时的皇家自然科学博物馆，德国的Wuppertal气候、能源研究所。

开源的云存储软件其实不少，我也先后测试了好几款，最后确认Seafile是目前性能最佳、功能较全、安装最方便的。感谢海文互知团队令人钦佩的工作成果！

搭建指南

1. Docker环境

Docker运行的基本需求是Linux x64，内核版本2.6.32-431或更高版本。具体请按照你的系统参考官方文档。

本例中我使用的Docker版本是1.6.1，docker version运行结果如下。

root@iZ255y3f595Z:/home# docker version
Client version: 1.6.0
Client API version: 1.18
Go version (client): go1.4.2
Git commit (client): 4749651
OS/Arch (client): linux/amd64
Server version: 1.6.0
Server API version: 1.18
Go version (server): go1.4.2
Git commit (server): 4749651
OS/Arch (server): linux/amd64

2. 拉取jenserat/seafile镜像

jenserat/seafile镜像（查看详情）包含了Seafile运行的依赖环境和一些方便的脚本，使用docker pull jenserat/seafile:latest拉取该镜像的最新版本。下载完成后输入docker images命令可以查看下载到的镜像：

root@iZ255y3f595Z:/home# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
jenserat/seafile    latest              8ef4348733ff        5 weeks ago         325.3 MB

3. 下载Seafile

jenserat/seafile镜像中包含了下载Seafile的脚本，可惜其文件托管在Amazon ECS上，国内无法正常访问。

所以我们需要从官方网站上手动下载，撰写本文时最高版本是4.1.2。存放进一个目录并将Seafile解压缩，注意保证此目录所在分区有足够空间（其实也不用太在意，之后空间不足后可以很方便的迁移）。本例中我们把Seafile存放在/home/app/seafile。

root@iZ255y3f595Z:/home/app/seafile# ls -l
total 19836
-rw-r--r-- 1 root root 20308273 May  5 17:17 seafile-server_4.1.2_x86-64.tar.gz
root@iZ255y3f595Z:/home/app/seafile# tar -zxf seafile-server_4.1.2_x86-64.tar.gz
root@iZ255y3f595Z:/home/app/seafile# ls -l
total 19840
drwxrwxr-x 6  500  500     4096 Mar 29 08:35 seafile-server-4.1.2
-rw-r--r-- 1 root root 20308273 May  5 17:17 seafile-server_4.1.2_x86-64.tar.gz

4. 配置

使用如下命令启动一个Docker容器来配置Seafile，注意将/home/app/seafile换成你的目录。

docker run -t -i --rm -p 10001:10001 -p 12001:12001 -p 8000:8000 -p 8080:8080 -p 8082:8082 -v /home/app/seafile:/opt/seafile jenserat/seafile -- /bin/bash

容器启动后看到如下输出：

*** Running /etc/my_init.d/00_regen_ssh_host_keys.sh...
*** Running /etc/rc.local...
*** Booting runit daemon...
*** Runit started as PID 9
*** Running /bin/bash...
root@635064a090b9:/# May 10 08:37:40 635064a090b9 syslog-ng[20]: syslog-ng starting up; version='3.5.3'

下面我们在容器中运行setup-seafile.sh脚本后按提示进行配置，本例中我们配置为通过域名sf.disksing.com访问，各种端口一路回车用默认的就行，因为我们可以在启动Docker容器时设置端口映射。

root@635064a090b9:/# cd /opt/seafile/seafile-server-4.1.2/
root@635064a090b9:/opt/seafile/seafile-server-4.1.2# ./setup-seafile.sh

You are running this script as ROOT. Are you sure to continue?
[yes|no] yes

-----------------------------------------------------------------
This script will guide you to config and setup your seafile server.

Make sure you have read seafile server manual at

        https://github.com/haiwen/seafile/wiki

Note: This script will guide your to setup seafile server using sqlite3,
which may have problems if your disk is on a NFS/CIFS/USB.
In these cases, we sugguest you setup seafile server using MySQL.

Press [ENTER] to continue

What would you like to use as the name of this seafile server?
Your seafile users will be able to see the name in their seafile client.
You can use a-z, A-Z, 0-9, _ and -, and the length should be 3 ~ 15


What is the ip or domain of this server?
For example, www.mycompany.com, or, 192.168.1.101

[This server's ip or domain] : sf.disksing.com

What tcp port do you want to use for ccnet server?
10001 is the recommended port.
[default: 10001 ]

Where would you like to store your seafile data?
Note: Please use a volume with enough free space.
[default: /opt/seafile/seafile-data ]

What tcp port would you like to use for seafile server?
12001 is the recommended port.
[default: 12001 ]

What tcp port do you want to use for seafile fileserver?
8082 is the recommended port.
[default: 8082 ]


This is your config information:

server name:        disksing
server ip/domain:   sf.disksing.com
server port:        10001
seafile data dir:   /opt/seafile/seafile-data

-----------------------------------------------------------------
Seahub is the web interface for seafile server.
Now let's setup seahub configuration. Press [ENTER] to continue
-----------------------------------------------------------------

-----------------------------------------------------------------

run seafile server:     ./seafile.sh { start | stop | restart }
run seahub  server:     ./seahub.sh  { start <port> | stop | restart <port> }

-----------------------------------------------------------------
If the server is behind a firewall, remember to open these tcp ports:
-----------------------------------------------------------------

port of ccnet server:         10001
port of seafile server:       12001
port of seafile fileserver:   8082
port of seahub:               8000

When problems occur, refer to

      https://github.com/haiwen/seafile/wiki

for more information.

配置完成后启动Seafile的两个服务测试，seafile是文件管理引擎，seahub提供网页访问服务。seahub首次启动时会要求提供管理员邮箱及密码：

root@635064a090b9:/opt/seafile/seafile-server-4.1.2# ./seafile.sh start

Starting seafile server, please wait ...
Seafile server started

Done.
root@635064a090b9:/opt/seafile/seafile-server-4.1.2# ./seahub.sh start

Starting seahub at port 8000 ...

----------------------------------------
It's the first time you start the seafile server. Now let's create the admin account
----------------------------------------

What is the email for the admin account?
[ admin email ] [e-mail]

What is the password for the admin account?
[ admin password ]

Enter the password again:
[ admin password again ]



----------------------------------------
Successfully created seafile admin
----------------------------------------



Loading ccnet config from /opt/seafile/ccnet
Loading seafile config from /opt/seafile/seafile-data

Seahub is started

Done.

现在用浏览器打开http://<youdomain_or_ip>:8000，看到登录页面说明配置完成了。输入exit退出并关闭当前容器。

root@635064a090b9:/# exit
exit
*** /bin/bash exited with status 0.
*** Shutting down runit daemon (PID 12)...
*** Killing all processes...

5. 启动Seafile

刚才我们已经在容器内正常启动了Seafile，只是如果每次都要手动操作略显麻烦，所幸jenserat/seafile提供了自动调用启动脚本的机制，创建容器时定义autostart=true即可。

这次我们给容器取一个有意义的名字seafile，如果你想让通过80端口访问，将-p 8000:8000改为-p 80:8000就可以了。

docker run -d \
  --name seafile \
  -p 10001:10001 \
  -p 12001:12001 \
  -p 8000:8000 \
  -p 8080:8080 \
  -p 8082:8082 \
  -v /home/app/seafile:/opt/seafile \
  -e autostart=true \
  jenserat/seafile

这份指南到这里就结束了，祝玩得开心！
