ISPConfig

ISPConfig is an open-source control panel for managing Linux servers through a web browser. It's designed for anyone who needs to administer hosting services, from a single server to a large, distributed network. The system lets you manage multiple servers from one central interface. It's free and transparent.

The panel is flexible. You can use it to manage a standalone server, a multi-server setup, or even a mirrored cluster for high availability. It works equally well on physical hardware and virtual machines. This architecture supports administrators who need to scale their infrastructure.

It handles all the essential hosting tasks.

• Websites: Manage sites on Apache2 or nginx web servers.
• Email: Set up and control email accounts using Postfix (SMTP) and Dovecot (POP3/IMAP).
• Databases: Create and manage MariaDB and MySQL databases.
• DNS: Configure DNS zones with BIND or PowerDNS servers.
• File Transfer: Administer FTP users with PureFTPD.
• System Tasks: Schedule Cron jobs and manage shell users.
• Networking: Full support for both IPv4 and IPv6.

ISPConfig provides four distinct access levels to separate permissions. Administrators have full control, while Resellers can manage their own clients. The Client level gives customers control over their own websites, email, and databases. There is also a simple login for individual email users. The interface is translated into more than 20 languages, and it runs on major Linux distributions like Debian, Ubuntu, AlmaLinux, and RockyLinux. The project has a large community with support forums and documentation, and commercial enterprise support is also available.
