nginx shows 200 ok status but doesn't load page

Question

I have installed nginx,php7.0-fpm and mysql on my ubuntu 16.04 server. Everything works fine however It doesn't load a setup page of phpmyadmin. Below is my phpmyadmin nginx block.

location /phpmyadmin { root /usr/share/; index index.php index.html index.htm; location ~ ^/phpmyadmin/(.+\.php)$ { try_files $uri =404; #fastcgi_pass 127.0.0.1:9000; fastcgi_pass unix:/run/php/php7.0-fpm.sock; include fastcgi_params; } } 

Below are my nginx access logs

/usr/share# tail -f /var/log/nginx/access.log 127.0.0.1 - - [15/Oct/2016:17:13:06 +0530] "GET /phpmyadmin/setup/index.php HTTP/1.1" 200 31 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0" 127.0.0.1 - - [15/Oct/2016:17:13:06 +0530] "GET /phpmyadmin/setup/index.php HTTP/1.1" 200 31 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0" 127.0.0.1 - - [15/Oct/2016:17:13:41 +0530] "GET /phpmyadmin/setup/index.php HTTP/1.1" 200 31 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0" 127.0.0.1 - - [15/Oct/2016:17:13:44 +0530] "GET /phpmyadmin/setup/index.php HTTP/1.1" 200 31 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0" 127.0.0.1 - - [15/Oct/2016:17:13:46 +0530] "GET /phpmyadmin/setup/index.php HTTP/1.1" 200 31 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0" 127.0.0.1 - - [15/Oct/2016:17:13:46 +0530] "GET /phpmyadmin/setup/index.php HTTP/1.1" 200 31 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0" 127.0.0.1 - - [15/Oct/2016:17:13:47 +0530] "GET /phpmyadmin/setup/index.php HTTP/1.1" 200 31 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0" 127.0.0.1 - - [15/Oct/2016:17:13:47 +0530] "GET /phpmyadmin/setup/index.php HTTP/1.1" 200 31 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0" 127.0.0.1 - - [15/Oct/2016:17:21:26 +0530] "GET /phpmyadmin/setup/index.php HTTP/1.1" 200 31 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0" 127.0.0.1 - - [15/Oct/2016:17:21:28 +0530] "GET /phpmyadmin/setup/index.php HTTP/1.1" 200 31 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0" 

I do not have anything in nginx error log. php7.0-fpm is also running normally below is the log extract of the same.

 tail -f /var/log/php7.0-fpm.log [15-Oct-2016 17:09:48] NOTICE: fpm is running, pid 17062 [15-Oct-2016 17:09:48] NOTICE: ready to handle connections [15-Oct-2016 17:09:48] NOTICE: systemd monitor interval set to 10000ms [15-Oct-2016 17:21:10] NOTICE: Terminating ...

[15-Oct-2016 17:21:11] NOTICE: configuration file /etc/php/7.0/fpm/php-fpm.conf test is successful [15-Oct-2016 17:21:11] NOTICE: fpm is running, pid 17297 [15-Oct-2016 17:21:11] NOTICE: ready to handle connections [15-Oct-2016 17:21:11] NOTICE: systemd monitor interval set to 10000ms 

I need expert advice on this as I tried to change php-fpm listen mode from localhost port 9000 to php.sock. Same can observed in phpmyadmin nginx block config.

With the exception of the phpmyadmin addition, typically your /etc/nginx/sites-available/default file should look like so in order for it to process PHP:

# Add index.php to the list if you are using PHP index index.html index.htm index.nginx-debian.html; server_name _; location / { # First attempt to serve request as file, then # as directory, then fall back to displaying a 404. try_files $uri $uri/ =404; } # pass PHP scripts to FastCGI server # location ~ \.php$ { include snippets/fastcgi-php.conf; # With php-fpm (or other unix sockets): fastcgi_pass unix:/var/run/php/php7.0-fpm.sock; # # With php-cgi (or other tcp sockets): # fastcgi_pass 127.0.0.1:9000; } # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /\.ht { # deny all; #} } 

So when you open a .php file in your browser, this location directive will process .php files including the file fastcgi-php.conf and it will pass the php script to php7.0-fpm.

Immediately after making any changes to any Nginx configuration file, test the configuration file like so sudo nginx -t, if all is well you should see this output:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful 

Then type sudo service nginx reload

You can test it out by adding a ghi.php file that will contain this snippet:

<?php phpinfo(); ?> 

You want to go to cd /var/www/html and from inside of there you can do sudo vim ghi.php

Then you go to your <server-ip-address>/ghi.php and if you don't see anything then your server is still not processing php.
