在本博客文章中，将介绍如何在Ubuntu 20.04 | 18.04上安装Seafile Server。
Seafile Server是一个开源，企业，自托管文件托管平台，用于性能和高可靠性。
Seafile使我们可以在我们自己的服务器上放置文件，并允许其他人和不同设备同步和访问它。
我们可以访问所有文件作为虚拟磁盘。

Seafile的特点

内置文件加密：在与服务器同步之前加密文件。
即使系统管理员也无法查看文件.Drive客户端：使用驱动器客户端访问云中的文件 local S: drive如果没有同步它们。
可靠的文件同步：具有可靠且有效的文件同步，它可以提高Productivity.easy来升级：可以通过在几秒内运行一个简单的脚本来完成升级：Seafile支持 AD/LDAP集成，组同步，细粒度权限控制使工具轻松应用于企业环境。

Seafile服务器要求

http server - nginx或者apache
database服务器 - mysql或者mariadbpython工具

在下载和设置Seafile服务器之前，我们的安装步骤将开始安装上述软件要求。
请按照下面的步骤在Ubuntu 20.04 | 18.04上安装Seafile Server。

第1步：安装MariaDB数据库服务器

使用以下步骤从安装MariaDB数据库服务器。

sudo apt update
sudo apt install mariadb-server

安全MariaDB数据库服务器：

sudo mysql_secure_installation

更改身份验证插件以允许使用root密码。

$sudo mysql -u root
UPDATE mysql.user SET plugin = 'mysql_native_password' WHERE User = 'root';
FLUSH PRIVILEGES;
QUIT;

在安装MariaDB数据库服务器后，为Seafile创建用户和数据库。

首先登录MySQL Shell作为root用户：

$mysql -u root -p
Enter password: 
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 48
Server version: 10.3.11-MariaDB-1:10.3.11+maria~bionic-log mariadb.org binary distribution
Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]>

Seafile Server的三个组件需要自己的数据库：CCNet ServerseAile ServerseAhub服务器

我们将为每个服务器组件创建一个数据库。

CREATE DATABASE seafile_server;
CREATE DATABASE ccnet_server;
CREATE DATABASE seahub_server;

创建数据库用户并授予创建的数据库的权限。

CREATE USER 'seafile'@'localhost' IDENTIFIED BY 'StrongPassword';
GRANT ALL ON seafile_server.* TO 'seafile'@'localhost';
GRANT ALL ON ccnet_server.* TO 'seafile'@'localhost';
GRANT ALL ON seahub_server.* TO 'seafile'@'localhost';
QUIT;

通过登录数据库确认访问 seafile用户：

$mysql -u seafile -pStrongPassword
Enter password: 
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 49
Server version: 10.3.11-MariaDB-1:10.3.11+maria~bionic-log mariadb.org binary distribution
Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> SHOW DATABASES;
+--------------------+
| Database           |
+--------------------+
| ccnet_server       |
| information_schema |
| seafile_server     |
| seahub_server      |
+--------------------+
4 rows in set (0.001 sec)
MariaDB [(none)]> QUIT
Bye

第2步：安装Python依赖项

Seafile大量取决于Python及其模块。
通过在终端中运行以下命令，在Ubuntu 20.04/18.04上安装所需的python依赖关系。

Ubuntu 20.04：

sudo apt update
sudo apt install python3 python3-{pip,pil,ldap,urllib3,setuptools,mysqldb,memcache,requests}
sudo apt install libpython3.8 ffmpeg

Ubuntu 18.04：

sudo apt update
sudo apt install python python-{pip,pil,ldap,urllib3,setuptools,mysqldb,memcache,requests}
sudo apt install libpython3.6 ffmpeg

第3步：下载并安装Seafile Server

在下载之前检查Seafile服务器的最新版本。
本文可以在安装时过时。

就像这种写作一样，当前版本是 7.1.3

sudo apt -y install wget
export VER="7.1.3"
wget https://download.seadrive.org/seafile-server_${VER}_x86-64.tar.gz

下载文件后，将存档提取到 /srv目录。

sudo tar -xvf  seafile-server_${VER}_x86-64.tar.gz -C /srv
sudo mv /srv/seafile-server-${VER} /srv/seafile

只需要安装安装，只需运行安装程序脚本。

cd /srv/seafile/
sudo ./setup-seafile-mysql.sh

脚本将指导我们使用MySQL设置Seafile Server。

$sudo ./setup-seafile-mysql.sh 
Checking python on this machine ...

----------------------------------------------------------------
run seafile server:     ./seafile.sh { start | stop | restart }
run seahub  server:     ./seahub.sh  { start <port> | stop | restart <port> }
----------------------------------------------------------------
If you are behind a firewall, remember to allow input/output of these tcp ports:
----------------------------------------------------------------
port of seafile fileserver:   8082
port of seahub:               8000
When problems occur, Refer to
        https://github.com/haiwen/seafile/wiki for information.

Seafile服务器将在端口上运行 8082和海夫Web UI将在港口提供 8000。

启动Seafile服务

启动Seafile Server守护程序，该守护程序处理原始文件上传，下载和同步：

$cd /srv/seafile
$sudo ./seafile.sh start 
[12/15/18 05:08:27] ../common/session.c(132): using config file /srv/conf/ccnet.conf
Starting seafile server, please wait ...
Seafile server started
Done.

然后启动Seahub(Django)Web Frontend服务：

$sudo ./seahub.sh start 
LC_ALL is not set in ENV, set to en_US.UTF-8
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 ] Hyman@theitroad
What is the password for the admin account?
[ admin password ] <ENTER ADMIN PASSWORD>
Enter the password again: <CONFIRM ADMIN PASSWORD>
[ admin password again ] 
---------------------------------------
Successfully created seafile admin
---------------------------------------
Seahub is started
Done.

如果我们遇到了语言环境设置的问题，请将其设置如下：

echo "export LC_ALL=en_US.UTF-8" >>~/.bashrc
echo "export LANG=en_US.UTF-8" >>~/.bashrc
echo "export LANGUAGE=en_US.UTF-8" >>~/.bashrc
source ~/.bashrc

添加行 ~/.bashrc文件有持久LC设置。

第4步：创建Seafile Systemd服务

我更喜欢用Systemd管理Seafile。
为Seafile Backend服务器创建一个系统单元文件。

sudo tee  /etc/systemd/system/seafile.service<<EOF
[Unit]
Description=Seafile
After= mysql.service
After=network.target
[Service]
Type=forking
ExecStart=/srv/seafile-server-latest/seafile.sh start
ExecStop=/srv/seafile-server-latest/seafile.sh stop
[Install]
WantedBy=multi-user.target
EOF

还为Seahub创建一个

sudo tee  /etc/systemd/system/seahub.service<<EOF
[Unit]
Description=Seafile
After= mysql.service
After=network.target
[Service]
Type=forking
ExecStart=/srv/seafile-server-latest/seahub.sh start
ExecStop=/srv/seafile-server-latest/seahub.sh stop
[Install]
WantedBy=multi-user.target
EOF

启动并启用服务以启动启动：

sudo systemctl daemon-reload
sudo systemctl start seafile && sudo systemctl enable seafile
sudo systemctl start seahub && sudo systemctl enable seahub

确认服务状态：

# systemctl status  seafile

步骤5：配置Nginx反向代理

既然我们拥有运行的服务，是时候将nginx配置为对Seafile服务器的反向代理。

sudo apt -y install nginx

创建一个新的配置文件 /etc/nginx/conf.d/seafile.conf具有以下内容。

server {
    listen 80;
    listen [::]:80;
    server_name  fileserver.example.com;
    autoindex off;
    client_max_body_size 100M;
    access_log /var/log/nginx/seafile.com.access.log;
    error_log /var/log/nginx/seafile.com.error.log;
     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 $server_name;
            proxy_read_timeout  1200s;
        }
     location /seafhttp {
            rewrite ^/seafhttp(.*)$ break;
            proxy_pass http://127.0.0.1:8082;
            proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_connect_timeout  36000s;
            proxy_read_timeout  36000s;
            proxy_send_timeout  36000s;
            send_timeout  36000s;
        }
    location /media {
            root /srv/seafile-server-latest/seahub;
        }
}

输入Seafile服务器域名 http://example.com
