Linux Hosting Consulting

Zwiegnet specializes in reliable, cost-effective Linux shared hosting solutions powered by Virtualmin (built on Webmin) on enterprise-grade distributions such as AlmaLinux, Rocky Linux, Ubuntu LTS, and Debian. We help businesses, developers, and agencies deploy and manage multi-tenant hosting platforms that support websites, mailboxes, databases, and DNS — without the high costs of proprietary panels like cPanel.

Our Linux hosting services include:

• Virtualmin Installation & Configuration – Automated setup on fresh Linux servers (AlmaLinux, Ubuntu, Debian), choosing between GPL (free) or Pro edition, with optimal defaults for shared hosting performance and security.
• Shared Hosting Environment Design – Multi-domain/virtual server setup, resource limits (CPU, memory, disk, bandwidth), plan templates, and reseller/sub-account delegation (Pro features).
• Web & Application Server Setup – Apache or NGINX (with PHP-FPM), multiple PHP versions, Let's Encrypt SSL automation, WordPress/CMS install scripts, and one-click app installations.
• Email & DNS Management – Postfix/Dovecot mail server configuration, SPF/DKIM/DMARC, ClamAV/SpamAssassin anti-spam, full DNS (BIND) control, and email deliverability tuning.
• Database & Backup Solutions – MySQL/MariaDB/PostgreSQL per-domain databases, automated backups (local/remote), scheduling, and restore procedures.
• Security Hardening & Compliance – Firewall (firewalld/iptables), ModSecurity, fail2ban, SELinux/AppArmor, two-factor authentication, isolated user accounts, and regular vulnerability scanning.
• Migration & Upgrades – Seamless migration from cPanel, Plesk, DirectAdmin, or legacy shared hosts; domain/email/database transfers with minimal downtime.
• Performance Optimization – Caching (Redis/Memcached), OPCache tuning, NGINX reverse proxy, resource monitoring, and scaling to VPS/dedicated/cloud instances.
• Integration & Automation – WHMCS billing integration, Ansible for orchestration, API scripting, LDAP/FreeIPA authentication, and custom hooks/scripts.
• Troubleshooting & Support – Diagnosing mail delivery issues, SSL errors, slow sites, quota problems, and ongoing maintenance/monitoring.

Ideal for web agencies, small-to-medium hosting providers, businesses needing private shared hosting, or organizations moving away from expensive commercial panels — we deliver secure, flexible Linux hosting that gives you full control and reduces costs.
