liups.com, also known as "Blue Book's Private Garden", is a personal Chinese-language technical blog. According to the author, the domain was registered back in 2015. The site was migrated from WordPress to Hexo, hosted on GitHub, and powered by Vercel and Cloudflare. Its content scope is very clear: databases, Linux operation and maintenance, and cloud service practices, mixed with personal logs about running, marathons and daily life.
The main value of this site lies in its experience-based technical articles. Crawled content shows a large number of posts related to Oracle, MySQL, PostgreSQL, TiDB, OceanBase, SQLite, as well as operation and maintenance and cloud practice content covering iptables/firewalld, LVM, Docker, VNC, rclone, MinIO, Cloudflare R2, Oracle Cloud, and more. Articles are almost always centered around real-world problems, such as TiDB etcd API security hardening, Oracle error recovery, abnormal MySQL startup, disk space troubleshooting, etc., complete with actual commands, scripts and troubleshooting thought processes.
This is a public personal blog, no membership tiers, paid courses, paywalled downloads or paid consulting packages were found. All crawled articles are free to read, and some content also links to corresponding GitHub repositories or script documentation.
Pros: It is highly practical and beginner-friendly for Chinese-speaking readers, especially useful for DBAs and system administrators looking for quick references when facing specific errors. The author has documented problems in the same field continuously from 2016 to the present, building up a very solid long-term accumulation of knowledge. Cons: As a personal blog, it naturally lacks a structured, systematic course framework. Article quality and applicability are highly dependent on your specific environment. Some content covering older versions of databases, CentOS 6, Oracle 11g/12c and other outdated software carries timeliness risks, so you must cross-check with official documentation before using any content in a production environment.
It is a great fit for Oracle/MySQL/TiDB DBAs, Linux system administrators, backend engineers, cloud service tinkerers, and technical readers who want to reference real-world troubleshooting workflows. It is not well-suited for total beginners who need a systematic learning tutorial, nor for enterprise decision-making scenarios that require formal SLA or official support.
According to the site content, there is a mirror at liups.cn, and the author mentions that run.liups.com is hosted on Tencent EdgeOne Pages to speed up access for visitors inside China. The main site relies on GitHub, Vercel and Cloudflare for hosting. Based on our crawl test, the main site is accessible from China, though access speed may vary by region due to the overseas static hosting infrastructure. Overall assessment: Free, content-rich, and practice-oriented, it is a very worthwhile personal knowledge repository to bookmark for DBAs and operations engineers.
