• Hi 🙂

    Sorry if I’m not in the right category.

    It’s nothing compared to @phenomlab and for all that he gives us but here’s a small contribution.

    I use the excellent software Wiki.js for my Wiki and I wrote this script and I share it with you


    Informations


    – The script allows you to automatically upgrade Wiki.js.

    – It pre-checks the installed version and compares it with the latest available on GitHub.

    – A backup of Wiki.js is made before the version upgrade in a defined directory.

    – The script has a –rollback option which allows you to return to the version installed before the execution of the script thanks to the backup if a problem occurs. (This does not prevent having another backup on hand 🙂 )


    Use


    – Copy and adapt the code below and paste it into a file named upgrade-wikijs.sh :

    nano upgrade-wikijs.sh
    

    – Make the script executable :

    chmod +x upgrade-wikijs.sh
    

    – Use it :

    ./upgrade-wikijs.sh
    
    ./upgrade-wikijs.sh --rollback
    

    CODE


    – I consider postgreSQL database engine is installed for Wiki.js
    This is the best possible choice for the future.

    – Adapt the code below :

    #!/bin/bash
