hosting codeigniter project to linux server

Hello bealefay ! The issue is not coming from CI, it is your apache configuration.

1/ You need to make sure PHP is installed. You can type "php -v" in the Terminal to make sure it is ok.

2/ "000-default.conf" needs to point to the "public" folder, not the root folder ("<Directory /path/to/public>"). I suggest you set up a virtualhost.

3/ "000-default.conf" needs to load "index.php", not "index.html".
