Installation · E4S Infrastructure Documentation

Quick Install

Quick Install prepares the minimum operating-system tools, reads the Layer1 catalog, downloads the latest eligible Universal installer, validates its SHA256 checksum and starts the installation.

Recommended Quick Install

curl -fsSL https://layer1.e4s.network/quick-install.sh -o /tmp/e4s-quick-install.sh
chmod +x /tmp/e4s-quick-install.sh
/tmp/e4s-quick-install.sh

Do not pipe an interactive installer directly into Bash.

Download the script first and execute it from a real terminal so prompts can read from the controlling TTY.

Manual Universal installer

Manual installation

chmod +x E4S-Infrastructure-VERSION-Universal-Linux.run
./E4S-Infrastructure-VERSION-Universal-Linux.run --verify-only
./E4S-Infrastructure-VERSION-Universal-Linux.run

The Universal wrapper detects the Linux family and selects the embedded Debian/Ubuntu or RHEL-family installer.
