"Primary script unknown" PHP - php

Question

I am trying to use PHP in my machine. I have nginx server running few other servers along.
Due to curiosity on how to use PHP , i tried to install php-cli and php5-fpm.
The nginx file below seems to work , however on front-end i get the error " 404". When i checked the error log , i found the error
"2016/03/29 14:28:50 [error] 19752#0: *1 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: ::1, server: localhost, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "localhost:84"
So i am assuming either my php5-fpm configuration is wrong or my nginx config is wrong .
Here is my nginx configuration file:
server {
listen 84 default_server;
listen [::]:84 default_server ipv6only=on;
root /usr/share/nginx/html;
index index.html index.htm;
server_name localhost;
location / {
index index.php index.html index.htm;
root /home/sijan/personal/php_site;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
#fastcgi_split_path_info ^(.+\.php)(/.+)$;
#fastcgi_pass unix:/var/run/php5-fpm.sock;
#fastcgi_index index.php;
#include fastcgi_params;
}
}
I followed the following link from Digital Oceans and skip few steps to install MySQL since i will be using psql.
Any Help will be Highly appreciated.

I can't immediately see anything wrong with your nginx config but I've found that PHP-FPM and Nginx can be really really temperamental when configuring... Try the following Nginx config instead...
server {
listen 84 default_server;
listen [::]:84 default_server ipv6only=on;
root /usr/share/nginx/html;
index index.php index.html index.htm;
server_name _;
location / {
index index.php index.html index.htm;
root /home/sijan/personal/php_site;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_index index.php;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_connect_timeout 10;
fastcgi_send_timeout 180;
fastcgi_read_timeout 180;
fastcgi_buffer_size 512k;
fastcgi_buffers 4 256k;
fastcgi_busy_buffers_size 512k;
fastcgi_temp_file_write_size 512k;
fastcgi_intercept_errors on;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
fastcgi_keep_conn on;
include fastcgi_params;
}
}
Also, don't forget that you've got your Nginx server listening on port 84 in your config, not the standard port 80.
