System Administrator / DevOps (hosting, Linux, high-load)
23 USD System Administrator / DevOps (hosting, Linux, high-load)
Format: project work
Employment: remote
Payment: negotiable (fixed for deployment + support / bonuses)
🎯 Project Goal
Build a commercial hosting infrastructure designed for 500+ websites, where:
- one problematic site does not affect the others
- resources are predictably limited
- the system is stable 24/7
- scaling does not turn into chaos
The candidate must understand that this involves:
- isolation of sites (CPU / RAM / PHP processes)
- control of PHP-FPM
- disk subsystem with high IOPS (NVMe)
- predictable operation of MySQL/MariaDB
- protection against "noisy" clients
- monitoring and backups
- absence of manual "firefighting"
🔨 Tasks
- Deploy Linux server(s) for hosting
- Set up virtualization (Proxmox / KVM — to be discussed)
- Install and configure the panel:
- DirectAdmin / ISPmanager / Plesk (by agreement)
- Configure web stack:
- Nginx / Apache
- PHP-FPM (with limits)
- MariaDB / MySQL
- Implement site isolation:
- CloudLinux or
- cgroups / systemd / containers
- Set up security:
- firewall
- Fail2Ban / ModSecurity or analogs
- Set up backups (not on the same disk)
- Set up monitoring (CPU / RAM / disk / I/O wait)
- Prepare infrastructure for growth (500 → 1000 sites)
- Document architecture and key settings
✅ Mandatory Requirements
- Real experience in administering Linux servers
- Understanding how shared hosting works
- Experience with:
- PHP-FPM
- MySQL/MariaDB
- WordPress and other CMS
- Understanding bottlenecks:
- CPU vs IOPS vs RAM vs network
- Ability to limit resources rather than "adding hardware"
- Responsibility and independence
⭐ Will be a big plus
- Experience launching hosting or VPS provider
- Experience with Proxmox / LXC
- Experience optimizing MySQL for high-load
- Experience working with NVMe / RAID / ZFS
- Automation (bash / ansible)
- Understanding scaling without downtime
💰 Payment
- fixed for deployment (via Safe)

Good day, Ilya.
To separate resources on virtual hosting, I recommend CloudLinux + any compatible control panel. I will set up correct limits (LVE) and file system (CageFS) restrictions.
I have worked in a hosting company for over 10 years, so I have extensive experience in configuring servers for virtual hosting and virtual private servers (VPS). I have configured virtual hosting servers that hosted more than 2,000 websites and over 500 clients. So feel free to reach out, I will help and advise on how to do it better.

Доброго дня. Питання яке треба вирешити на хмарах чи on-prem
-
Пока предлагают вариант
- Linux (Debian/Ubuntu)
- LXC
- MariaDB отдельно
- Nginx
- Панель управления (ISPmanager или аналог)
Наверное єто оптимальній вариант… но предлагайте
-
Дякую за відповідь. Але це структура інфраструнтури. А питання було в тому де розгортати інфраструктуру на хмарах (AWS, GCP та Azure). Або на серверах Proxmox та Openstack
-
Вот бачу у вас у завданії (Proxmox / KVM — обсуждается). Але є питання це ваш особистий сервер чи якогось закладу?
