Nginx with angular and codeigniter applications in subfolders - php

Question

I'm trying to make a website with codeigniter in the backend and angularjs in the frontend.
For the backend I'm using nginx as a server.
Currently I have problems with proper configuration of the nginx. What I want to achieve is to have codeigniter and angularjs applications in separate folders. And What I want is to access as follows
codeigniter from my_website.com/api
angular from my_website.com
And in terms of folder I want to keep them in:
codeigniter: /var/www/html/api
angular: /var/www/html/angular
So far I've manage to make it work from the same folder. So now I have codeigniter in /var/www/html and angular folder is in the same directory. And that way I can access codeigniter from my_website.com/ and angular from my_website.com/app which is not what I want.
I was trying multiple different setups for nginx /etc/nginx/sites-available/default file, but every single time with some problems. Farthest I've got was to have those in separate folders but codeigniter was working only for default_controller and I couldn't access any other files.
That's the current working config.
server {
listen 80;
listen [::]:80 default_server ipv6only=on;
root /var/www/html;
server_name localhost;
index index.php index.htm index.html;
location /app/ {
root /var/www/html/angular;
try_files $uri/ $uri index.html =404;
}
location / {
try_files $uri $uri/ /index.php;
#index index.html;
}
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;
include fastcgi_params;
}
}
And here is simple config where I just try to run codeigniter from demo sub-folder,
server {
listen 80;
server_name localhost;
root /var/www/html;
autoindex on;
index index.php;
location / {
#try_files $uri $uri/ /index.php;
try_files $uri $uri/ /index.php$request_uri;
location = /demo/index.php {
try_files $uri $uri/ /index.php$request_uri;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
fastcgi_param SCRIPT_FILENAME /var/www/html/demo$fastcgi_script_name;
include fastcgi_params;
}
}
location ~ \.php$ {
return 444;
}
}
And here my_website.com/demo/index.php works fine but my_website.com/demo/index.php/welcome shows 500 Internal Server Error
I hope I make myself clear.
I tried so many different configs found online, but I always had some troubles with that. Can any of you propose some simple solution for that problem?
Thanks,
Mateusz

I've finally managed to make it work the way I want. I've used this solution link to make it work with codeigniter in sub-directory which was the main problem. Here is my config:
server {
listen 80;
server_name localhost;
root /var/www/html;
autoindex on;
index index.html;
location / {
root /var/www/html/angular;
try_files $uri/ $uri index.html =404;
}
location /api/ {
alias /var/www/html/api/;
try_files $uri $uri/ /api/index.php;
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_index index.php;
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
include /etc/nginx/fastcgi_params;
fastcgi_param SCRIPT_FILENAME $request_filename;
}
}
location ~ \.php$ {
return 444;
}
}
Thanks to #FrédéricHenri for suggesting using the log file under /var/log/nginx/*.log, that helped with tracking the way nginx is redirecting requests. Also what I've encounter was that web-browser was caching the website(I think that is what was happening) so that was giving me false results while I was making some changes to the config file.

If you have already set up ~ .php and other stuff. then Just need to add
location /ci-project {
try_files $uri $uri/ /ci-project/index.php;
}
In your server {} object of Nginx configuration
