Self-hosting Guide

Notices: ⚠️ Before hosting, make sure your server can communicate securely with HTTPS and link it to a domain name. All deploy script is based on Let’s Encrypt certificates, you can customize with your own SSL certificate providers. ⚠️ dev mode intends for HTTP transmission, prod mode intends for https transmission.

Without Docker

1. Get binary executable file

If you want to alter the source code and build yourself, make sure you have golang environment in your server, then run the script below to get and build a binary file:

go get github.com/LouisYLWang/Sync-Sofa/server
# If you don't know $GOPATH
# try "go env GOPATH"
cd $GOPATH/src/github.com/LouisYLWang/Sync-Sofa/server

# Next step is optional
# If you have any error message like:
# "dial tcp 216.58.200.49:443: i/o timeout"
# then try
export GOPROXY=https://goproxy.io

go install
cd $GOPATH/bin

If you want to only deploy the binary file:
1. Open Github release page
2. Download server binary file for linux server
3. Download config.json file to the same directory of binary file

2. In the directory of binary file, adjust config file base on your need:

Config file variables:
- addr: port of server
- runmode:
  - dev: developing mode
  - prod: producting mode
- tlsdir: TLS certificate paths
  - tlskey: TLS certificate privatekey path
  - tlscert: TLS certification path
Notices: addr, runmode are mandatory, tlskey, tlscert are required for TLS connection

minimal (non-https) config file:

{
  "addr": ":80",
  "runmode": "dev"
}

production environment (https) config file:

{
  "addr": ":443",
  "runmode": "prod",
  "tlsdir": {
    "tlskey": "/etc/letsencrypt/live/your.host.url/privkey.pem",
    "tlscert": "/etc/letsencrypt/live/your.host.url/fullchain.pem"
  }
}

3. Run ./server to delopy the server, deployment is successful if you see:

  found config file, read parameters from config file...
  server is listening at {your_port_number}...

With Docker

Make sure docker service is runing on your server, make change to the script blow and run:

variables
- ADDR: port of server
- RUNMODE:
  - dev: developing mode
  - prod: producting mode
- APIHOST: your host name
- IMGNAME: your docker image name, set arbitrarily
- TLSKEYPATH: TLS certificate privatekey path
- TLSCERTPATH: TLS certification path

minimal (non-https) hosting script:

docker pull louisylwang/watchtogether

export ADDR=:4000 \      
export RUNMODE=dev \   
export IMGNAME=yourimagename \   

docker run -d \
-e ADDR=:4000 \
-e RUNMODE=RUNMODE \
-p 4000:4000 \
--name IMGNAME louisylwang/watchtogether

production environment (https) hosting script:

docker pull louisylwang/watchtogether

export ADDR=:443 \      
export RUNMODE=prod \   
export APIHOST=your.host.name \   
export IMGNAME=yourimagename \   
export TLSKEYPATH=/your/path/to/TLS/privatekey \
export TLSCERTPATH=/your/path/to/TLS/certification \


docker run -d \
-e ADDR=:ADDR \
#docker port to server:server port to docker, not necessarily the same
-p ADDR:ADDR \ 
-e RUNMODE=RUNMODE \
#if you use letsencrypt, TLSKEY value should be /etc/letsencrypt/live/$APIHOST/privkey.pem
-e TLSKEY=TLSKEYPATH \ 
#if you use letsencrypt, TLSCERT value should be /etc/letsencrypt/live/$APIHOST/fullchain.pem 
-e TLSCERT=TLSCERTPATH \ 
#need to expose your TLS certification file to docker
-v /etc/letsencrypt:/etc/letsencrypt:ro \ 
--name IMGNAME louisylwang/watchtogether \
--restart=always

deployment is successful if you see in docker logs {your docker image name}:

not found config file, read parameters from system variables...
YYYY/MM/DD HH:MM:SS server is listening at :ADDR...

FAQ

Q: When I installed, Chrome popup says that Sync Sofa requires the permissions of read and change your data on a number of websites and read your browsing history, sounds so horrible, is that safe? A: We do not collect your browsing data, the only thing we do is to get your current tab information and make sure you are visiting a site we support (support list). All information is collected and processed locally. We do not mess up the data on the websites you are watching, just inject a sync script to get your pause, play, and seek operation. All source code can be reviewed at our github page, we promise everything we did is necessary and not harmful.
If your find your extension button is darken, please first make sure you are in a video playing page.
If you find your extension can not request room code, please first check the option page and click RESET button. If it still not work, please close your web browser, wait for a while and try again. Currently our server is hosting abroad, it may cause connecting issue.

服务端部署指南

注意:

⚠️ 部署前，建议你的服务器已经部署了SSL/TLS证书，并已连接到域名。以下部署脚本基于使用Let’s Encrypt certificates验证的服务器，如使用其他的证书提供商，可能需要修改部分脚本以正常运行。

⚠️ dev模式使用http协议进行传输，prod使用https协议进行传输

直接部署（不使用Docker容器）:

1. 获取执行文件

如果你想要修改源代码并自行编译，请执行以下shell脚本获取二进制文件。在执行前，请确认服务器已安装Go的环境

go get github.com/LouisYLWang/Sync-Sofa/server
# 如果你不清楚 $GOPATH
# 请尝试输入并执行 "go env GOPATH"
cd $GOPATH/src/github.com/LouisYLWang/Sync-Sofa/server

# （下一步可省略）
# 如果你看到了这条消息:
# "dial tcp 216.58.200.49:443: i/o timeout"
# 请添加并执行下一条命令
export GOPROXY=https://goproxy.io

go install
cd $GOPATH/bin

如果无需修改源代码并自行编译，你也可以直接下载二进制文件:
1. 打开 Github release page
2. 下载 server 文件（适用于linux服务器）
3. 下载 config.json 文件，移动至server同一路径

2. 修改配置文件：

配置变量：
- addr: 服务器端口
- runmode:
  - dev: 开发模式（建议本地使用，不包含对HTTPS的支持）
  - prod: 生产模式
- tlsdir:
  - tlskey: TLS证书私钥路径
  - tlscert: TLS证书路径
Notices: addr, runmode 为必须参数, tlskey, tlscert 参数在使用HTTPS连接时（生产环境下）为必须参数

开发模式（http）配置文件样例:

{
  "addr": ":80",
  "runmode": "dev"
}

生产模式（https）配置文件样例:

{
  "addr": ":443",
  "runmode": "prod",
  "tlsdir": {
    "tlskey": "/etc/letsencrypt/live/your.host.url/privkey.pem",
    "tlscert": "/etc/letsencrypt/live/your.host.url/fullchain.pem"
  }
}

3. 在执行文件所在路径下，执行 ./server 部署服务器, 部署成功信息如下:

  found config file, read parameters from config file...
  server is listening at {your_port_number}...

使用Docker容器部署

在部署前请确认Docker容器在服务器端可正常运行，请按照如下提示修改参数

配置变量：
- ADDR: 服务器端口
- RUNMODE:
  - dev: 开发模式（建议本地使用，不包含对HTTPS的支持）
  - prod: 生产模式
- APIHOST: 服务器网址
- IMGNAME: docker容器名称（可自选）
- TLSKEYPATH: TLS证书私钥路径
- TLSCERTPATH: TLS证书路径

开发模式（http）配置文件样例:

docker pull louisylwang/watchtogether

export ADDR=:4000 \      
export RUNMODE=dev \   
export IMGNAME=yourimagename \   

docker run -d \
-e ADDR=:4000 \
-e RUNMODE=RUNMODE \
-p 4000:4000 \
--name IMGNAME louisylwang/watchtogether

生产模式（https）配置文件样例:

docker pull louisylwang/watchtogether

export ADDR=:443 \      
export RUNMODE=prod \   
export APIHOST=your.host.name \   
export IMGNAME=yourimagename \   
export TLSKEYPATH=/your/path/to/TLS/privatekey \
export TLSCERTPATH=/your/path/to/TLS/certification \


docker run -d \
-e ADDR=:ADDR \
#docker port to server:server port to docker, not necessarily the same
-p ADDR:ADDR \ 
-e RUNMODE=RUNMODE \
#if you use letsencrypt, TLSKEY value should be /etc/letsencrypt/live/$APIHOST/privkey.pem
-e TLSKEY=TLSKEYPATH \ 
#if you use letsencrypt, TLSCERT value should be /etc/letsencrypt/live/$APIHOST/fullchain.pem 
-e TLSCERT=TLSCERTPATH \ 
#need to expose your TLS certification file to docker
-v /etc/letsencrypt:/etc/letsencrypt:ro \ 
--name IMGNAME louisylwang/watchtogether \
--restart=always

常见问题

Q: 在我安装的时候，Chrome提示我Sync Sofa可以读取和更改您在一些网站上的数据以及读取您的浏览记录，听起来很严重，它安全吗？

A: 我们不会收集你的浏览数据，我们只会读取你当前标签页的标题，用来判断你是否在访问我们支持的页面(支持网站列表)，以避免影响使用体验的事情发生。所有对你浏览数据的收集和处理只会发生在本地；事实上我们也不会随意修改网站的数据，我们只会使用一个同步脚本来监测你播放，暂停及更新进度等操作（我们不得不这样做）。所有的源码都可以在 [我们的项目主页]审核(https://github.com/LouisYLWang/Sync-Sofa), 我们承诺目前做的所有事情都是必要且无害的.
如果你发现按钮变灰, 请确认你是否在我们支持的网站操作(支持网站列表).
如果你发现插件无法获取同步码，请按以下顺序检查问题：
1. 请检查选项页面并点击重置 按钮
2. 请参考选项页面根据你所在的位置选择并设置合适的服务器
3. 请检查服务器当前状态 https://sync-status.onns.xyz/是否正常启动
4. 如以上都不能解决你的问题，请通过项目反馈页面或项目wiki页面右下角的反馈按钮通知我们。
如果你发现插件无法正常同步操作，请按以下顺序检查问题：
1. 请务必确认两方版本号是否一致，欲检测版本号，需打开chrome extension page，并找到Sync Sofa - Online Video Synchronizer *.*.*，其中 *.*.* 为当前版本。
2. 请检查选项页面并点击重置 按钮
3. 请参考选项页面根据你所在的位置选择并设置合适的服务器
4. 请检查服务器当前状态 https://sync-status.onns.xyz/是否正常启动.
5. 如以上都不能解决你的问题，请通过项目反馈页面或项目wiki页面右下角的反馈按钮通知我们。

如何获取调试信息

在选项页里打开 debug模式。
刷新视频页面。
Shift + ctrl + i 在 Windows 下或者 Shift + cmd + i 在 MacOS 下.
选择 console 标签页.

VLC同步功能无法正常使用

首先确认http://127.0.0.1:8080/能否正常打开，如果不能，请查看一下8080端口是否被其它应用程序占用。如果该程序可以被关闭，请关闭后再次尝试开启。

如果不能，请参考相关配置将VLC的端口号设置为9891。（将在v1.0.10之后生效）

如果可以打开http://127.0.0.1:8080/，但页面无法正常渲染，请尝试开启科学上网后再次刷新页面。（页面需要加载google的一个js文件）
