Linux

Once Fast-Https is installed on a Linux server, it ships a default site: open port 80 of the server in a browser and you will see a welcome page. Pick one of the three methods below and do not mix them.

Check two things first

Run every command on this page in the server’s terminal, not on your own computer. Log in to the server and run:

cat /etc/os-release
uname -m

The first command reports the distribution: Ubuntu or Debian means the .deb method; CentOS, Rocky, AlmaLinux or openEuler means the .rpm method.
The second reports the processor architecture: x86_64 maps to amd64 in download filenames, aarch64 maps to arm64. Most cloud servers are x86_64.

If you are still unsure, or your distribution is not listed, choose archive deployment: it is just a compressed file and does not depend on a package manager.

Which one should I pick

Your system	Choose	Notes
Ubuntu / Debian	Install on Ubuntu	`apt` installs a `.deb` package and registers a system service
CentOS / RHEL family	CentOS 7 installation and deployment	`yum` installs an `.rpm` package and registers a system service
Other distributions / no package manager	Archive deployment	Unpack a `.tar.gz` and run it; register the service yourself

.deb and .rpm are Linux package formats: they are recorded by the system package manager and can be upgraded or removed centrally. A .tar.gz is a compressed archive that unpacks directly into program files, without a package manager.

Before you start

You need an account that can log in to the server and run administrative commands: either root, or an account that prefixes commands with sudo.
The default site uses port 80 (HTTP) and 443 (HTTPS). On a cloud server, allow both ports in the provider’s security group / firewall first, or the site will be unreachable from outside.
Neither port may be occupied by another program (for example an existing Nginx). Each guide below includes a command to check.

Installation options

Install on UbuntuInstall the server .deb package, start the systemd service and verify the default site
CentOS 7 installation and deploymentInstall with yum on RPM-based distributions and run under systemd
Archive deploymentStart and verify the default site from the .tar.gz archive

After installation

Each of the three guides includes verification commands and the day-to-day commands for starting and stopping the service. To publish your own site, configure a reverse proxy or set up HTTPS, see the Tutorials section in the sidebar.
