1 理论基础

1.1 简介

Seafile 是一个开源的文件云存储平台，更注重于隐私保护和对团队文件协作的支持。
Seafile 通过“资料库”来分类管理文件，每个资料库可单独同步，用户可加密资料库，且密码不会保存在服务器端，所以即使是服务器管理员也无权访问你的文件。
Seafile 允许用户创建“群组”，在群组内同步文件、创建维基、发起讨论等，方便团队内协同工作

1.2 软件许可协议

Seafile 及其桌面、移动客户端遵循 GPLv3。
Seahub（Seafile 服务器的 web 端）遵循 Apache License。

1.3 部署的要求

要求安装以下组件：
python 2.7 (从 Seafile 5.1 开始，python 版本最低要求为2.7）
python-setuptools
python-imaging
python-mysqldb
python-ldap
python-urllib3
python-memcache (或者 python-memcached)

1.4 Seafile的系统架构

如上图所示，Seafile 包含以下系统组件：
Seahub – 网站界面，供用户管理自己在服务器上的数据和账户信息。Seafile服务器通过”gunicorn”（一个轻量级的Python HTTP服务器）来提供网站支持。Seahub作为gunicorn的一个应用程序来运行。
Seafile server (seaf-server) – 数据服务进程, 处理原始文件的上传/下载/同步。
Ccnet server (ccnet-server) – 内部 RPC 服务进程，连接多个组件。
Controller – 监控 ccnet 和 seafile 进程，必要时会重启进程。
注：
所有 Seafile 服务都可以配置在 Nginx/Apache 后面，由 Nginx/Apache 提供标准的 http(s) 访问。
当用户通过 seahub 访问数据时，seahub 通过 ccnet 提供的内部 RPC 来从 seafile server 获取数据。

2 实践部分

2.1 环境信息

2.1.1 主机信息

hostname=seafile.cmdschool.org
ip address=10.168.0.53
os type=CentOS Linux release 7.2

2.1.2 域名解析

配置dns解析或配置host解析，host解析配置如下（客户端和服务端）：

vim /etc/hosts

加入如下内容：

10.168.0.53   seafile.cmdschool.org

2.1.3 关闭selinux

setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

2.2 yum源和安装包

New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!
[...]
Remove anonymous users? [Y/n] y
 ... Success!
[...]
Disallow root login remotely? [Y/n] n
 ... skipping.
[...]

 ... Success!
 - Removing privileges on test database...
 ... Success!
[...]
Reload privilege tables now? [Y/n] y

修改启动参数如下：

#!/bin/sh

# 请将 user 改为你的Linux用户名
user=seafile

# 请将 script_dir 改为你的 Seafile 文件安装路径
seafile_dir=/home/cmdschool.org
script_path=${seafile_dir}/seafile-server-latest
seafile_init_log=${seafile_dir}/logs/seafile.init.log
seahub_init_log=${seafile_dir}/logs/seahub.init.log

# 若使用 Nginx/Apache, 请将其设置为true, 否者为 false
fastcgi=true
# fastcgi 端口, 默认为 8000.
fastcgi_port=8000

case "$1" in
        start)
                sudo -u ${user} ${script_path}/seafile.sh start >> ${seafile_init_log}
                if [  $fastcgi = true ];
                then
                        sudo -u ${user} ${script_path}/seahub.sh start-fastcgi ${fastcgi_port} >> ${seahub_init_log}
                else
                        sudo -u ${user} ${script_path}/seahub.sh start >> ${seahub_init_log}
                fi
        ;;
        restart)
                sudo -u ${user} ${script_path}/seafile.sh restart >> ${seafile_init_log}
                if [  $fastcgi = true ];
                then
                        sudo -u ${user} ${script_path}/seahub.sh restart-fastcgi ${fastcgi_port} >> ${seahub_init_log}
                else
                        sudo -u ${user} ${script_path}/seahub.sh restart >> ${seahub_init_log}
                fi
        ;;
        stop)
                sudo -u ${user} ${script_path}/seafile.sh $1 >> ${seafile_init_log}
                sudo -u ${user} ${script_path}/seahub.sh $1 >> ${seahub_init_log}
        ;;
        *)
                echo "Usage: /etc/init.d/seafile-server {start|stop|restart}"
                exit 1
        ;;
esac

2.5.4 添加执行用户和配置目录权限

useradd seafile -s /sbin/nologin -d /home/cmdschool.org/
chown -R seafile:seafile /home/cmdschool.org/
chown -R seafile:seafile /tmp/seahub_cache/

2.5.5 配置启动服务

2.5.11 浏览器测试

http://seafile.cmdschool.org

2.6 配置nginx的https代理

注：以下配置基于2.5章节

2.6.1 生成私钥

生成如下私钥：

privkey.pem

2.6.2 生成公钥

openssl req -new -x509 -key privkey.pem -out cacert.pem -days 1095

向导如下：

You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:GD
Locality Name (eg, city) [Default City]:DG
Organization Name (eg, company) [Default Company Ltd]:cmdschool.org

          fastcgi_param   HTTPS               on;
          fastcgi_param   HTTP_SCHEME         https;

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