Craft CMS server requirements checker.

Craft Server Check

This script checks if a web server meets the minimum requirements to run a Craft 3 installation.

Usage

Run the following in a terminal of any *nix environment (e.g. Linux, MacOS, WSL).

curl -Lsf https://raw.githubusercontent.com/craftcms/server-check/HEAD/check.sh | bash

Alternatively, you can upload the server folder to your web server's public html folder and load checkit.php from your browser or upload server anywhere on your server and execute php checkit.php from the console to see the results.

Shell exit codes

If all requirements are met, the script will return an exit code of 0.

The script will return an exit code of 1 if:

  • Any errors are encountered, or requirements are not met

  • An environment variable CRAFT_STRICT_SERVER_CHECK=1 is set, and any warnings are found:

    CRAFT_STRICT_SERVER_CHECK=1 php server/checkit.php
    

This can be espically useful in a CI/CD pipeline, or a Dockerfile, where you want the process to fail if the check does not pass:

# Dockerfile
FROM php:8.0-fpm
RUN curl -Lsf https://raw.githubusercontent.com/craftcms/server-check/HEAD/check.sh | bash

The official Craft Docker Images run this check when building to be certain all of Craft's requirements are met in any built image.
