You need to be able to upload files to the Raspberry Pi web server. One way is to use FileZilla using your SSH connection rather than an ftp connection. FileZilla is a free to download application that uses drag and drop and is quite easy to use.
Download and install FileZilla from https://filezilla-project.org/
The web pages are normally located at /www/var/html/ although if you are using a USB flash drive as described above, you may have moved this to another location which in my example is /websites/www/html/
The user that you use to login with SSH needs to own the files.
So if we go into the Terminal and change directory to /www/var/html/ and then type:
you may see that the owner:group is root:root
The above command lists the files and directories with full details.
If you try to connect using FileZilla and try to upload a file, it will give permissions denied.
To overcome this we set the owner of the files using:
In our example, we need to set the user and group to the Apache user and group which in our case is www-data:www-data
So to change the user, group we do:
Or if we are using the USB Flash drive we do:
