ppa:ondrej/nginx 的用途是什么？

Question

我刚刚添加ppa:ondrej/php到我的 ubuntu 服务器上，它提示我以下消息。

为什么建议我也添加ppa:ondrej/nginx（稳定）？这样做的具体目的是什么？

有关信息我已经从官方文档安装了 Nginx 。

我不太了解个人包档案 (PPA)，因此我希望获得一些有关其工作原理的帮助。

Answer 1

此外，还ppa:ondrej/nginx包括 brotli nginx 模块，该模块未包含在官方 Ubuntu nginx 软件包中，这使得这个 ppa 现在非常有用，因为 brotli 受到大多数浏览器的支持，并且提供比 gzip 更好的压缩。

此外，它是最新的稳定版本（例如，官方 Ubuntu:focal 存储库具有 nginx 1.18，但 ppa:ondrej/nginx 具有 nginx 1.20）。

Answer 2

根据 的主页，ppa:ondrej/nginx这里是 PPA 描述：

This branch follows latest NGINX Stable packages compiled against latest OpenSSL for HTTP/2 and TLS 1.3 support.

BUGS&FEATURES: This PPA now has a issue tracker: https://deb.sury.org/#bug-reporting

所以是的，目的与ppa:ondrej/php安装最新的 Nginx（稳定）版本相同。
