我的网盘，我做主

家里一直想弄个 nas ，怎奈qiong【穷】，一直没弄成。在蛮早的时候就就接触过 seafile 这个软件了。趁着今天有时间，折腾折腾一下。

最想要的是文件同步的功能，就类似于360网盘那种直接挂载到本地，当本地盘用。用来做做文件的备份和不同PC间的文件共享，也希望可以修改后能实时同步。需求就是这么简单。

现在手上就一个旧的 16G 闪迪U盘，一张 16G 的 microSD 卡，一块 Raspberry Pi 2 板子。为了满足张大妈的需求，我还是贴上链接吧。

闪迪（SanDisk）酷铄(CZ73) USB3.0 金属U盘 16GB 读130MB/秒42.9元京东去购买

Micro SD 卡在淘宝或者京东自己搜一下吧，也就30~40左右。记得是class4的哦。

Raspberry Pi 2 板子 199元，也就自行淘宝吧，放上链接有推销的嫌疑。现在都出3了，可以买3试下。

贴上我家的大怪兽，第一次搞这么“牛逼哄哄”的路由器，有点小激动。

华硕（ASUS）RT-AC88U 游戏路由 3167M双频全千兆低辐射/智能无线路由器/MU-MIMO吃鸡路由/支持AiMesh1399元京东去购买

好了进入今天的正题：

0. 需要有外网IP

需要有外网IP， 需要有外网IP， 需要有外网IP

重要的事情说三遍。你可以去 这个网站 看下IP 和自己路由器里面拨号的IP是否一致。如果一致，则说明是 外网IP。

1. 安装 Raspbian GNU/Linux 9.4 (stretch) 系统；

   
   

此处省略1万字，自行谷歌好了。

2. 需要 DDNS

因为前不久才入手的一台 ASUS AC88U “大怪兽”，所有 DDNS 自然用的是华硕自己的。请看图，原谅我懒，AC88U 懒得嗮图了。就只贴下DDNS的设置吧。

备注：

在“外部网络”→“DDNS”菜单栏中，将“启用DDNS客户端”选择“是”，然后主机名称自己填，例如："example",完整的地址就是：example.asuscomm.com。"example" 字样可以换成你喜欢的任何英文字符。

3. 购买域名

我是在阿里云的万网里面注册的两个域名，然后在域名中添加一条CNAME 记录，指向 example.asuscomm.com 这个域名。如下图所示：

4. 将U盘插上去

新建一个 /mnt/usb 目录

用命令 fdisk -l 查看那个是 U盘，我们这边是 /dev/sda4：

大致看下容量，然后确定是 /dev/sda，然后我们在 fdsik -l /dev/sda 看下具体信息

$ sudo fdisk -l |grep ^Disk
... ...
Disk /dev/mmcblk0: 14.9 GiB, 15931539456 bytes, 31116288 sectors
Disklabel type: dos
Disk identifier: 0x1d363ad8
Disk /dev/sda: 11.4 GiB, 12213813248 bytes, 23855104 sectors
Disklabel type: dos
Disk identifier: 0xcad4ebea

$ sudo fdisk -l /dev/sda

Disk /dev/sda: 11.4 GiB, 12213813248 bytes, 23855104 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xcad4ebea

Device Boot Start End Sectors Size Id Type
/dev/sda4 * 63 23855103 23855041 11.4G c W95 FAT32 (LBA)

将U盘挂载信息写入 fstab文件中，以实现开机自动挂载：

$ sudo echo "/dev/sda4 /mnt/usb vfat defaults 0 0"

$ mount -a

$ df -h /mnt/usb/
Filesystem Size Used Avail Use% Mounted on
/dev/sda4 12G 5.8G 5.7G 51% /mnt/usb

U盘到此就配置完成了。

5. 下载并配置Seafile

下载链接双手奉上

下载 Raspberry Pi 服务器端软件包。

官方的安装手册我在这也双手奉上

知道你们是老手老司机，但也不要怪我多嘴。我还是大致说下步骤吧。

1). 更新系统；

$ sudo apt-get update

$ sudo apt-get upgrade

2). 安装必须的依赖软件：

$ sudo apt-get install python2.7 libpython2.7 python-setuptools python-imaging
python-ldap python-mysqldb python-memcache python-urllib3 sqlite3

3). 安装 MariaDB 数据库（非必须）

此处省略1万字，自行谷歌好了。

4). 新建一个目录，我计划是将安装文件放在 /usr/local/seafile 目录下,tar.gz 压缩包放在 installed 目录下

$ sudo mkdir -p /usr/local/seafile/installed

$ sudo cp seafile-server_6.2.5_stable_pi.tar.gz /usr/local/seafile/installed

5). 解压文件，并查看下目录结构树

$ sudo tar -zxvf seafile-server_6.2.5_stable_pi.tar.gz -C /usr/local/seafile/

$ tree -L 2 /usr/local/seafile

/usr/local/seafile/
├── installed
│ └── seafile-server_6.2.5_stable_pi.tar.gz
└── seafile-server-6.2.5
├── check_init_admin.py

├── seahub
├── seahub.sh
├── setup-seafile-mysql.py
├── setup-seafile-mysql.sh
├── setup-seafile.sh
└── upgrade

6-1). 加入安装了 MariaDB 数据库，配置如下：

$ sudo /usr/local/seafile/seafile-server-6.2.5/setup-seafile-mysql.sh

6-2). 如果没有配置Mariadb,默认会用 sqlite

$ sudo /usr/local/seafile/seafile-server-6.2.5/setup-seafile.sh

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

Make sure you have read seafile server manual at

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.

7). 安装配置 nginx

$ sudo apt-get install nginx

增加 seafile.conf 的 nginx 控制配置文件

$ sudo vi /etc/nginx/sites-available/seafile.conf
server {
listen 80;
server_name expleam.cc;

proxy_set_header X-Forwarded-For $remote_addr;

location / {
proxy_pass http://127.0.0.1:8000;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $server_name;
proxy_read_timeout 1200s;

# used for view/edit office file via Office Online Server
client_max_body_size 0;

access_log /var/log/nginx/seahub.access.log;
error_log /var/log/nginx/seahub.error.log;
}

# If you are using [FastCGI](http://en.wikipedia.org/wiki/FastCGI),
# which is not recommended, you should use the following config for location `/`.
#
# location / {
# fastcgi_pass 127.0.0.1:8000;
# fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

#
# client_max_body_size 0;
#
# access_log /var/log/nginx/seahub.access.log;
# error_log /var/log/nginx/seahub.error.log;
# }

location /seafhttp {
rewrite ^/seafhttp(.*)$ $1 break;
proxy_pass http://127.0.0.1:8082;
client_max_body_size 0;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_connect_timeout 36000s;

}
location /media {

}
}

8). 启动 seafile 和 seahub

$ sudo /usr/local/seafile/seafile-server-6.2.5/seafile.sh start

第一次启动 seahub 时会要求你设置一个admin账号，显示如下：

$ sudo /usr/local/seafile/seafile-server-6.2.5/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 ] expleam@163.com admin 账号设置

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

Enter the password again:
[ admin password again ]

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

Seahub is started

Done.

查看端口监听是否正常

$ netstat -tlunp |egrep "8082|8000"
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 0 0 0.0.0.0:8082 0.0.0.0:* LISTEN -
tcp 0 0 0.0.0.0:8000 0.0.0.0:* LISTEN -

9). 路由器设置端口映射,如下图所示：

10). 网络登录上去查看,完全没问题

10). 下载安装Windows挂载版的软件

11). 软件安装完成后，会在我的电脑里面多出一个S盘

我们先用之前初始化的账号登录下，如下图所示：

登录完成后，会先获取文件列表

然后我们可以看到多了个 S盘

发现没有，可用空间 90.9TB，牛逼的很。不过这只是假象，千万别信。这逼装的到位不。

然后我这本身就已经有文件了，状态如下：

跟自己本地的盘一样的用，可以双击直接点开文档。

总结：

屌丝版实时文件同步。如果有钱，真心可以搞个专门的 Nas，我这只是因为工作数据比较重要，备了4份。

1份在本地硬盘，1份在SD卡上，1份在移动硬盘里面，1份就在这seafile服务器上。

经常换电脑，或者说笔记本和台式机上无缝实时拷贝，或者说修改文档，那是相当的好用。

花费总共：二级域名不用钱 + Micro SD + U盘 + Raspberry Pi 2 = 0 + 35 + 40 + 199 = 274

像我这样装个比，买个*级域名也就 15一年，原谅我qiong只买的起 .cc 结尾的。总工 274 就能搭建一个实时共享使用起来像本地硬盘的网络共享存储。那是相当的值啊。这个软件支持 MAC ,安卓，IOS，Window，Linux，ARM 几乎全平台适用。强大的一逼。喜欢动手的可以搞搞。下次自己租个 Nas ，装个 Linux 在慢慢折腾一下更牛逼的 Nas 好了。

我们的宗旨是：花小钱，办大事。我是“美国短跑名将”琼斯。

谢谢各位听我在这吹了这么久的水，灰常感谢。
