We configure Apache to listen in the port 80 and 443, if you want to access your site using https, we can help you with the changes in the Apache's configuration to force HTTPS, do you want that?
I don't know why your sitemap looks like that. You already made some changes in the application and that probably affected the sitemap information
As I mentioned, all the Ghosts files are inside the /opt/bitnami/apps/ghost/htdocs folder. In that case, and if you mean the redirects.json file, you will find it at
/opt/bitnami/apps/ghost/htdocs/content/data/redirects.json. The easiest way to modify that file is by downloading the current redirects file from the app and then upload the new one using the admin panel
I don't fully understand this, can you share a link with more information about what you are trying to achieve?
Grunt is already installed in the Bitnami Ghost solution.
chmod +x ./node_modules/grunt-cli/bin/grunt
but if you want to install globally, you can run the following commands
sudo npm install -g grunt-cli
sudo npm install -g bower
Could you please let us know the guide you are following?
Again, can you share with us the guide you are following when configuring Ghost?
