Complete procedures with a way back.

Issue identities from a trusted CA, protect private keys, require encrypted accounts, configure hostname verification, rotate certificates, and test downgrade resistance.

Build Apache, MariaDB, PHP-FPM, TLS, application identity, database credentials, health checks, and backups as one verified stack.

Build nginx, MariaDB, PHP-FPM, TLS, isolated application paths, FastCGI safety rules, health checks, and backups.

Create host-scoped accounts, assign roles, rotate credentials without exposing them in shell history, test grants, and retire access.

Install MariaDB from an official distribution or MariaDB repository, constrain networking, create an administrator path, enable logs, and prove restart safety.

Create a consistent logical backup with routines, events, triggers, metadata, compression, encryption, checksums, retention, and an isolated restore test.

Install the matching utility, take a streamed or directory backup, prepare redo logs, encrypt and copy it, then restore on an isolated compatible server.

Prepare compatible primary and replica servers, create a TLS-bound replication user, seed data, configure GTID replication, monitor lag, and test recovery.

Remove anonymous and test access, restrict administration, enforce TLS where remote clients are required, audit grants, and verify exposure.

Install from a trusted package or verified upstream release, isolate configuration secrets, add TLS and network authentication gates, disable dangerous defaults, and test database TLS.

Deploy phpMyAdmin on an isolated FPM pool, protect it with network and HTTP authentication, verify database TLS, deny unsafe paths, and validate updates.
