php - Nginx + php5-fpm = 404 Error with alias location -

i amateur front end web developer, , bought ubuntu server try hand @ backend development. trying figure out how serve php file aliased location block using php5-fpm. getting 404 - page not found error. have tried of proposed solutions find here no luck. still beginner love quick eli5 , pointers on rest of conf file, can learn too. should mention main root folder running flask app, , reason using aliased location.

my virtual host:

nginx conf file

server { listen 80; listen [::]:80; server_name www.example.com example.com;  root /var/www/example; large_client_header_buffers 8 32k; access_log /var/www/example/logs/access.log; error_log /var/www/example/logs/error.log;   location / {     proxy_http_version 1.1;     proxy_set_header upgrade $http_upgrade;     proxy_set_header connection "upgrade";     proxy_set_header x-real-ip $remote_addr;     proxy_set_header x-forwarded-for $remote_addr; #$proxy_add_x_forwarded_for;     proxy_set_header host $http_host;     proxy_set_header x-nginx-proxy true;     proxy_pass http://app_test;     proxy_redirect off; }    location /test_site {      alias /var/www/test_site;      index index.php index.html index.htm;      location ~ .php$ {                 try_files $uri =404;                 fastcgi_split_path_info ^(.+?\.php)(/.*)?$;                 fastcgi_pass unix:127.0.0.1:9000;                 fastcgi_index index.php;                 include fastcgi_params;      }   } 

php5 www.conf file

[www] ... user = www-data group = www-data   listen = 127.0.0.1:9000 #listen = /tmp/php5-fpm.sock  listen.owner = www-data listen.group = www-data listen.mode = 0660 ... 

my fastcgi_params file default. have checked both php , nginx logs , there no errors. appreciated!

getting alias work nested locations using fastcgi complicated.

assuming have not on simplified configuration, test_site location not need use alias:

location /test_site {     root /var/www;     index index.php index.html index.htm;     location ~ \.php$ {         try_files $uri =404;         fastcgi_pass unix:127.0.0.1:9000;         include fastcgi_params;     } } 

this removes alias directive, , solves aliasing problem in php block.

note also: regex on location ~ \.php$ block wrong. fastcgi_split_path_info , fastcgi_index directives unnecessary.

the nginx directives documented here.
