背景

将 Tweak 部署和更新到大量设备上的一个不错解决方案，是搭建私有Cydia源 ；而非通常的make package install 、dpkg -i;

• cydia_repo 的目录结构

deb 源本质上就是需要特定结构的目录

cydia--
         |--debs--*.deb
         |--Packages  :dpkg-scanpackages debs /dev/null > Packages ;Packages 文件中包含源中每个包文件的信息，包括文件路径、大小、依赖、架构及校验信息
         |--Packages.bz2 ：由Packages文件压缩而来, 命令行: bzip2 Packages；
         |--Packages.gz
         |--Release  ：是一个普通的文本文件，用于描述当前源的信息；这些信息会在 Cydia 的源列表及 Tweak 搜索列表中显示
         |--Release.gpg :Package Signatures,from our Release file. This file will be downloaded by the clients first and then is used to verify the validity of the Release file. gpg -abs -o Release.gpg Release

其中Packages.bz2 和debs 是必须，其他文件都是可选的。

正文

Cydia源服务器搭建

• 假设URL地址是 192.168.2.189/cydia, 对于本地的cydia目录来说, 结构如下

Cydia/
 --Release
 --Packages
 --Packages.gz
 --Packages.bz2
 --CydiaIcon.png
 --debs/
   --xxxx1.deb
   --xxxx2.deb

• 具体请看辅助脚本

dpkg-scanpackages: info: Wrote 1 entries to output Packages file.

• python -m SimpleHTTPServer 8088

测试的时候可以使用,这个命令简单的开启一个HTTPServer
#  部署方式
 ~/cydia 下执行python -m SimpleHTTPServer 8088  ，
 添加http://192.168.2.189:8088/cydia 源即可

• add cydia_repo

1) 在prints 脚本添加：

function kncydia {

    echo "[将自己的源地址添加到cyida 中]"
        # install.exec "echo -e '127.0.0.1 localhost \n192.168.2.107 xx.com' > /etc/hosts"
      echo -e 'deb http://192.168.2.69:8088/ ./ ' > /private/etc/apt/sources.list.d/wl.list#-e 参数是为了使用换行符\n
     # 清理VPN的垃圾log
     echo "" > /private/var/log/ppp.log
}

2) 手动添加其实等价于修改以下文件
/private/etc/apt/sources.list.d/cydia.list -> /var/mobile/Library/Caches/com.saurik.Cydia/sources.list

文件目录功能解释

• Packages

1）deb包索引文件, 保存了各个deb包的control文件的信息,以及各个deb包的文件信息.
2）该目录是 由 dpkg-scanpackages debs /dev/null > Packages 产生。

• Packages.bz2

由Packages文件压缩而来, 命令行: bzip2 Packages

• Release

Cydia源配置文件,客户端通过下载此文件来读取cydia源信息;
Release文件几乎不用改, 只要准备好deb文件, 然后用dpkg-scanpackage命令生成Packages就可以了

• CydiaIcon.png

an icon named "CydiaIcon.png" in your root dir so the user finds your repo at a glance.

知识补充

• cydia

由 Jay Freeman（saurik）和他的公司开发，用于安装、管理越狱设备上的第三方软件、插件。它移植了Debian上的包管理器dpkg并提供了图形化前端，方便普通用户使用。Cydia 中还有个 Cydia Store，提供付费的第三方应用。

• CydiaSubstrate

 iOS7 之前也叫MobileSubstrate，也是由saurik开发的。Cydia Substrate consists of 3 major components: MobileHooker, MobileLoader and safe mode.

• Electra

 Tweak 开发者 CoolStar 基于 async_awake、以及Comex 开发的 CydiaSubstrate 的开源替代: Substitute，开发了 Electra 越狱工具。支持 iOS11.0 - iOS 11.1.2 的全部 iOS 设备
