版本
Nginx官方定义了Mainline、Stable、Legacy三种版本。
1. Mainline version（主线版本）
该版本包含最新的功能和bug修复，被视为开发版，即正在活跃开发中的版本。其版本号通常为单数，例如1.25.5。这个版本的更新较快，可能会引入新的功能和修复，但也可能存在尚未解决的bug。
2. Stable version（稳定版本）
最新稳定版适合生产环境使用。其版本号通常为双数，例如1.26。这个版本经过充分测试和验证，bug较少，适合用于承载实际业务。因此，通常建议在生产环境中使用此版本。
3. Legacy versions（历史版本）
这些版本是之前发布的稳定版，对于需要特定旧版本的兼容性或安全性支持的用户有用。然而，这些版本一般不推荐用于新项目，除非有特殊需求。
源码
1. 只读存储库
- code: http://hg.nginx.org/nginx
- website: http://hg.nginx.org/nginx.org (mirror of GitHub repository)
2. GitHub库
- code: GitHub - nginx/nginx: An official read-only mirror of http://hg.nginx.org/nginx/ which is updated hourly. Pull requests on GitHub cannot be accepted and will be automatically closed. The proper way to submit changes to nginx is via the nginx development mailing list, see http://nginx.org/en/docs/contributing_changes.html (mirror of Mercurial repository)

3. 源URL
- URL：nginx – nginx
4. Linux包
稳定版本和主线版本的相关Linux软件包。

安装
Nginx一般可以使用apt/yum/dnf来安装二进制包，若需使用特定的功能模块，则需要使用源码安装。
- OS：Rocky Linux 9.3 (Blue Onyx)
