Install a single-node Elasticsearch service for websites on the same VPS, retaining TLS and authentication while preventing public access to HTTP and transport ports.
Servers and operations
Experience from developing and running websites, e-shops and servers. Practical, no marketing.
A small, fast in-memory service for PHP applications. This setup deliberately keeps Redis private to the VPS and defines persistence and memory behaviour explicitly.
Keep ISPConfig and modern applications on the primary database service, while isolating an older application in a separate, local-only MariaDB instance with its own SQL policy.
A repeatable pattern for serving legacy and current applications side-by-side with PHP-FPM, without changing the system-wide PHP runtime.
A command-led single-server installation of Apache, BIND, Postfix, Dovecot, Pure-FTPd, MariaDB and ISPConfig. Start with a fresh Debian 13 VPS; finish with a usable hosting panel.
