因为 app 开发的时候需要进行测试，每次频繁的拷贝发送；iOS 的企业包上传到分发平台无法通过，有限制等等。一部分开发者出于数据安全的考虑，更倾向于使用自有服务器部署搭建分发平台。
准备工作：
1.一个域名，国内服务器部署需使用已备案域名
2. 域名的SSL证书
生成域名ssl证书，iOS应用签名过程必须使用https才能完成，生成ssl证书后用Nginx格式下载。
3. 一台16核16G ssd 480G服务器 （系统使用linux7.x以上就行）
服务器
对于内测分发系统而言，服务器是最重要的。一个高配的服务器有助于增强IPA的分发速度和下载速度，满足用户的快速下载、分发等需求，提高用户的体验感，满足用户的使用需求，提高用户的体验。带宽峰值最低选择100Mbps，安装的时候才不影响用户下载速率。
如今的互联网行业竞争非常激烈，很多网站经常都会遭受很多不明流量的ddos攻击，所以分发平台在选择服务器时要把这个因素考虑在内，选择服务器时考虑高防服务器起始防御100G防患于未然。网站遭受不明流量ddos而导致分发长时间瘫痪无法使用的情况比比皆是，最后也因贪图一便宜而让app用户流失。
搭建内测分发系统以上三点基本算是一个完备的内测分发系统所需的配置。
