Virtualmin Server Management

We monitor your Virtualmin server without pause, covering CPU, memory, disk, inodes, the RAID array, and the response of every service Virtualmin and Webmin run: the Webmin and Usermin daemons (ports 10000 and 20000), Postfix, Dovecot, Apache, NginX, MySQL, MariaDB, PostgreSQL, PHP-FPM, BIND, FTP, and SSH. We also watch the Postfix mail queue for outbound-spam spikes. Custom website sanity checks, application probes, and port monitors are added on request, and alerts reach our Virtualmin server management queue rather than your phone.

Disaster recovery is the highest-priority work in your Virtualmin Server Management. When there is a server compromise, a failed drive, a deleted virtual server, or a database dropped in production, we work without stopping until your data is back. We restore at whatever level the incident needs: a full-server rebuild, a single virtual server from Virtualmin’s built-in backup, one database, or one mailbox. We pull from any backup you have, including Virtualmin’s own Backup and Restore (local, FTP, or cloud storage), the provider’s snapshot, R1Soft, JetBackup, or our optional Linux server backup, and where severity allows we can often recover a hacked or crashed server without one.

We run a CSF firewall with Login Failure Daemon tuned to your traffic, blocking brute-force attempts on Webmin and Usermin (ports 10000 and 20000), Postfix, Dovecot, FTP, and SSH. We harden Webmin and Virtualmin authentication with two-factor where you want it, run ModSecurity with a maintained ruleset, and add ImunifyAV or Imunify360 for malware on request. The Webmin panel and every domain get SSL through Virtualmin’s built-in Let’s Encrypt or your own certificate. We harden SSH and DNS, patch the kernel, secure /tmp, /var/tmp, and /dev/shm, and run CloudLinux where you have it. We assist with PCI compliance on e-commerce servers. Hardening is optional. We recommend it to every customer, and if you have any concerns, we can discuss it first and apply all of it, some of it, or none.

We complete Virtualmin server migrations with the lowest possible downtime. A final fast-sync runs just before the cutover, then DNS flips, and end users arrive on new Virtualmin server hardware without a status-page incident. We migrate Virtualmin-to-Virtualmin using Virtualmin’s built-in domain backup and restore, other-control-panel-to-Virtualmin, and bare-metal-to-cloud, from AWS EC2 to DigitalOcean or any source to any target. We also complete CentOS-to-AlmaLinux and CentOS-to-Rocky Linux distro migrations without losing customer data, and the hostname, DNS, mail, and SSL certificates cut over cleanly.

We tune Apache or NginX for your fleet, setting the PHP execution mode (FCGId or PHP-FPM) and PHP version per virtual server, so one busy site cannot starve the rest. We tune MySQL and MariaDB across buffers, thread cache, and slow-query hunting, plus PostgreSQL where you run it. We also enable HTTP/2, Brotli and gzip, an in-memory tmp, and Redis or Memcached object caching, and move MySQL data to NVMe where it is available.

You get unlimited 24/7/365 ticket support for anything on your Virtualmin server: blocked outbound email and SMTP bounces, IMAP and Dovecot connection issues, SSL and TLS certificate renewals, slow WordPress sites and wp-admin lockouts, DNS, SPF, DKIM, and CNAME changes, firewall and ModSecurity rule updates, cron failures, .htaccess and file permissions, malware scans, reboots, outages, and any system administration task you can describe in a ticket. Standard tickets respond in ten to thirty minutes, urgent in five to ten. We place no limit on tickets and bill nothing by the hour.

We keep your Virtualmin server’s patch level current. Webmin and Virtualmin update through the panel’s own update system, with module and PHP upgrades staged and a rollback ready. We run OS package updates, notify you of reboots, and apply security patches for major Linux outbreaks promptly. We also handle MySQL, MariaDB, and PostgreSQL version upgrades, including major-version moves on InnoDB and MariaDB Galera clusters.

When you need a new Virtualmin server, we build it in full: the Linux OS install, the Webmin and Virtualmin install (GPL or Pro), our hardening baseline, and configuration of the services you will host. We deploy Let’s Encrypt for valid SSL on every domain and configure the hostname plus forward and reverse DNS. DNS templates are ready for every domain you add, with DKIM, SPF, and DMARC enabled on every mail domain. We migrate your existing websites, databases, and applications from the old server before the cutover.

We handle OS-level installs along with the Virtualmin pieces. We set up Apache or NginX with the PHP versions and execution mode each virtual server needs, MySQL, MariaDB, and PostgreSQL for databases, Postfix and Dovecot for mail, and BIND for DNS, which is the stack Virtualmin provisions. We also install Redis, Memcached, or Varnish for caching, ClamAV and SpamAssassin for mail hygiene, the Virtualmin Install Scripts for one-click apps, and CloudLinux with CageFS for tenant isolation. We add Java and Tomcat, Git, Node.js, Python, and Ruby where an app calls for them, along with most third-party Linux software that has an install path.

We configure Postfix the Virtualmin way, setting mail authentication (SPF, DKIM, DMARC) and per-domain outbound limits so one hijacked virtual server cannot torch your IP reputation. We also handle Dovecot IMAP and POP3, Usermin and Roundcube webmail lockouts, ProcMail recipes and server-side filtering, SMTP relay and smart-host setup, SpamAssassin and mail-queue triage, mailbox quota issues, bounce-loop diagnosis. These are the everyday mail tasks hosting companies forget to ask for until they break.

We also take on Virtualmin root work, virtual server template edits, reseller and user account changes, DNS zone work, SSH access management, cron jobs, certificate installation and renewal, firewall rule changes, .htaccess and file permissions, log file analysis, Virtualmin script installer triage, and WordPress and wp-admin recovery. The brief jobs and the lengthy ones get the same attention.
