Uninstalling a dynamic module

This section describes how to uninstall an F5 NGINX Plus dynamic module.

You may need to uninstall a dynamic module in NGINX Plus in several scenarios:

  • The module is being replaced with a newer or alternative version. For example, the OpenTracing module has been replaced by the OpenTelemetry module. The Cookie-Flag dynamic module has been superseded by natively supported proxy_cookie_flags directive.

  • The module is no longer supported, for example, the NGINX ModSecurity WAF module.

  • The operating system is not supported by the module. See the the Dynamic Modules section of the NGINX Plus Technical Specifications.

  • The module it is no longer required, uninstalling it helps optimize resource usage and reduce maintenance overhead.

  • The module is causing runtime errors or configuration conflicts that affect stability or performance.

  • Security or compliance policies require removal, particularly in regulated environments where only approved or certified modules are allowed.

After uninstalling the package, you will need to disable the module in the NGINX configuration file.

  1. In a text editor, open the NGINX Plus configuration file:

    • /etc/nginx/nginx.conf for Linux
    • /usr/local/etc/nginx/nginx.conf for FreeBSD

  2. Disable dynamic loading of the module by removing the corresponding load_module directive.
