Percona Server for MySQL 8.4 LTS on Ubuntu 24.04 | Support by cloudimg

## Percona Server for MySQL 8.4 LTS on Ubuntu 24.04 by cloudimg

Percona Server for MySQL 8.4.8 LTS on Ubuntu 24.04 LTS (Noble Numbat), purpose-built for Microsoft Azure and maintained by cloudimg. Percona Server is a free, open-source, 100%-compatible drop-in replacement for MySQL Community Edition with enterprise-grade performance, scalability, and observability features — extra storage engines, advanced threadpool, deeper InnoDB telemetry, and longer LTS support windows than upstream MySQL.

Why Choose cloudimg?

* 24/7 Expert Support with guaranteed 24-hour response and 1-hour critical-issue average. Contact support@cloudimg.co.uk

* Production-Ready from Launch — security-patched, validated, and pre-configured before publication

* Azure-Native Integration — Azure Linux Agent, cloud-init, Gen2 Hyper-V boot

* Per-VM Credential Generation — both `root@127.0.0.1` (TCP) and `cloudimg` (application user) passwords rotated uniquely at first boot. `root@localhost` stays on `auth_socket` so customers can always recover via `sudo mysql`. Credentials written to `/etc/cloudimg-credentials.txt` (mode 0600).

* Memory-Tuned for Standard_B2s — `innodb_buffer_pool_size=256M`, `performance_schema=OFF`, `max_connections=100` keep the server stable on a 4 GB VM out of the box. Customers can raise these on larger sizes.

What is Included

* Percona Server for MySQL 8.4.8-8 LTS from `repo.percona.com/ps-84-lts`

* Bound to `127.0.0.1:3306` by default — open NSG port 3306 + change `bind-address` to `0.0.0.0` to allow remote clients

* `cloudimg` application user with full privileges on the `cloudimg` schema

* Anonymous users + test database removed at first boot

* percona-server-mysql-8-4-firstboot.service systemd one-shot

* mysql.service systemd unit auto-starting on boot

* Ubuntu 24.04 LTS base with latest security patches at build time

* Azure Linux Agent for SSH key injection and seamless cloud integration

Use Cases

* Drop-in upstream MySQL replacement for application backends

* Production OLTP database for SaaS workloads needing extended LTS

* Replication source/replica with ROW binlog format pre-configured

* Observability-heavy MySQL workloads (Percona's enhanced sys schema and performance counters)

* Migration target from upstream MySQL Community Edition with zero compatibility changes

Notes on Hardening

For production replication, set `server_id` uniquely per replica, configure `gtid_mode=ON`, and use `mysqldump` or Percona XtraBackup for snapshots. For TLS, generate certificates and add `ssl-ca`, `ssl-cert`, `ssl-key` to `/etc/mysql/mysql.conf.d/zz-cloudimg-percona.cnf`. Increase `innodb_buffer_pool_size` to ~50–75% of RAM on production-sized VMs.
