Ubuntu 14.04 – PHP Version Upgraded

php -v

Shows:

In the page the php code phpinfo();

phpinfo();

Shows:
PHP Version 5.5.9-1ubuntu4.19

Now to correct this you need to:

sudo a2dismod php5
sudo a2enmod php5.6
sudo service apache2 restart

Letsencrypt Combining plugins

Combining plugins

Sometimes you may want to specify a combination of distinct authenticator and installer plugins. To do so, specify the authenticator plugin with --authenticator or -a and the installer plugin with --installer or -i.

For instance, you could create a certificate using the webroot plugin for authentication and the apache plugin for installation.

certbot run -a webroot -i apache -w /var/www/html -d example.com
