CodeIgniter calls /index.php instead of /basefolder/index.php , on Nginx? - php

Question

I am running CodeIgniter 3.0.6 in an Nginx server and subpaths end up serving /index.php, rather than /<installdir>/index.php. So, if I ask for /CodeIgniter-3.0.6/home/ I get served the /index.php page instead, rather than /CodeIgniter-3.0.6/index.php as expected. Note, that my CodeIgniter application will eventually reside in /2016/.
I suspect this is down to a misconfiguration of my Nginx install, rather than something CodeIgniter related? My Nginx install is running on Ubuntu 16.04. The contents of the /etc/nginx/sites-enabled/default are:
location / {
try_files $uri $uri/ /index.php;
}
location ~ \.php$ {
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
include fastcgi.conf;
}
Is there something else I should be changing?

Answer 1

If your server has a single application with the main entry point at /CodeIgniter-3.0.6/index.php, you should probably set your locations like this:
location / {
try_files $uri $uri/ /CodeIgniter-3.0.6/index.php;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
include fastcgi.conf;
}
That way, any URI that is not a match for a resource file or a .php file, will be routed to your applications default entry point /CodeIgniter-3.0.6/index.php.
However, if there is more than one application, such that /index.php and /CodeIgniter-3.0.6/index.php are two distinct entry points, you may want to set up locations for each application, possibly like this:
location / {
try_files $uri $uri/ /index.php;
}
location /CodeIgniter-3.0.6 {
try_files $uri $uri/ /CodeIgniter-3.0.6/index.php;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
include fastcgi.conf;
}
That way, only URIs that begin with /CodeIgniter-3.0.6 will be routed to that application's default entry point.
