  1. Dear moderators, I found a possible typo in the first command-line box. dnf — is the default package manager for Fedora, and apt is for Ubuntu/Debian.

    • @Raghu

      The package in the official repositories of most if not all Linux distributions comes pre-compiled with OpenSSL-fips.

  2. I installed nginx on ubuntu 16.04 and configure sites available and sites enabled but my laravel application is not running to the server name (http://local.test) which I have provided.

    • @Lasse

      You are right, as you can see, we have zeroed down to the Nginx service management though. Many thanks for the useful feedback.

  3. This article looks mostly like an introduction to systemd’s systemctl. And the last command doesn’t even show the “Nginx Command Help”, it’s the help of systemctl.

    • @Oli

      Yes, your concern is true, but these are essentially Nginx service management systemctl commands. Thanks for the feedback.
