My_webapp documentation

In addition to the Readme.md of the app, here are some useful tips.

non-interactive login

This app creates a new user with very limited rights : use of sftp, and access to a /var/www/my_webapp(__#) directory (where # is a number in case of multiple installations of the app). Password login is enabled, with a Chroot to the directory. This forces you to update the contents of the website by hand, with a login and a password input. To allow non-interactive login, you must follow those steps :

• Enable public-key login in /etc/ssh/sshd_config, on the server
• Create a public/private key pair for your script, on your "redacting" computer
• Copy the public key in /var/www/my_webapp(__#)/.ssh/authorized_keys
• Adjust the owner of the file and directory to the webapp# user
• you may now login without a password input, using sftp -b, lftp or other sftp clients.

NB : The port number to use for SFTP connexions is the one used for SSH, specified in /etc/ssh/sshd_config.

This tip then allows for auto-update scripts of the site contents. (For example with the Pelican makefile : make ftp_upload)
