nginx trying to specify different locations not the main root - php

Question

I have a config that handles different "websites" a main root handles the requests for the main url and I specify a specific path for it, in another location /mailtracker I handle a different app and point it to a different directory. My problem is php-fpm is not finding this second location.
Basically I want to have several locations pointing to different roots.
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
root /var/www/sites/dorero/;
index index.php index.html index.htm;
# Make site accessible from http://localhost/
server_name localhost;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
# Uncomment to enable naxsi on this location
# include /etc/nginx/naxsi.rules
}
location /mailtracker {
alias /var/www/sites/mailtracker/web/;
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass 192.168.10.3:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
location ~ ^/(index|app|app_dev|config)\.php(/|$) {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
## NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
#
# # With php5-cgi alone:
fastcgi_pass 192.168.10.3:9000;
# # With php5-fpm:
# fastcgi_pass unix:/run/php/php7.0-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
I tryied specifying instead of $document_root the path to the alias /var/www/sites/mailtracker/web/ and it didn't work.
Output from the php-fpm to this config says:
192.168.10.4 - 06/Feb/2018:19:04:49 +0000 "GET /mailtracker/index.php" 404

Answer 1

Put location /mailtracker above location / because nginx matched route /mailtracker for / before checking /mailtracker
You can remove location ~ \.php$ inside location /mailtracker
Add try_files $uri $uri/ =404; to location /mailtracker
edit:
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
root /var/www/sites;
index index.php index.html index.htm;
# Make site accessible from http://localhost/
server_name localhost;
location #rewriteapp {
rewrite ^(.*)$ /app.php/$1 last;
}
location /mailtracker {
alias /var/www/sites/mailtracker/web;
set $subfolder "mailtracker/web";
try_files $uri #rewriteapp;
}
location / {
root /var/www/sites/dorero;
set $subfolder "dorero";
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
# Uncomment to enable naxsi on this location
# include /etc/nginx/naxsi.rules
}
location ~ ^/(index|app|app_dev|config)\.php(/|$) {
fastcgi_split_path_info ^(.+\.php)(/.+)$;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME $document_root/$subfolder/$fastcgi_script_name;
