Installing cgi-fcgi of Ubuntu

Connect to PHP-FPM Directly

Test PHP-FPM Ping Page

Test PHP-FPM Status Page

Directly connect to PHP-FPM

During debugging, we often need to isolate problem first to make sure if its really PHP problem or Nginx is doing something wrong.

In those cases, cgi-fcgi command might come handy.

Installing cgi-fcgi of Ubuntu

Just run following command:

			apt-get install libfcgi0ldbl
		

Connect to PHP-FPM Directly

Assuming you are running PHP-FPM using TCP/IP with IP and PORT values 127.0.0.1 and 9000 respectively, below are some code sample you may want to execute.

Test PHP-FPM Ping Page

I have posted about this at length here https://easyengine.io/tutorials/php/fpm-status-page/

You can run following codes from command line to test output:

			SCRIPT_NAME=/ping \
SCRIPT_FILENAME=/ping \
REQUEST_METHOD=GET \
cgi-fcgi -bind -connect 127.0.0.1:9000
		

Above will return output like below:

			Content-Type: text/plain
Expires: Thu, 01 Jan 1970 00:00:00 GMT
Cache-Control: no-cache, no-store, must-revalidate, max-age=0
pong
		

Test PHP-FPM Status Page

I have posted about this at length here https://easyengine.io/tutorials/php/fpm-status-page/

You can run following codes from command line to test output:

			SCRIPT_NAME=/status \
SCRIPT_FILENAME=/status \
REQUEST_METHOD=GET \
cgi-fcgi -bind -connect 127.0.0.1:9000
		

Above will return output like below:

			Expires: Thu, 01 Jan 1970 00:00:00 GMT
Cache-Control: no-cache, no-store, must-revalidate, max-age=0
Content-Type: text/plain

pool:                 www
process manager:      dynamic
start time:           08/Jan/2014:15:04:57 +0530
start since:          93492
accepted conn:        1215
listen queue:         0
max listen queue:     1
listen queue len:     0
idle processes:       26
active processes:     4
total processes:      30
max active processes: 34
max children reached: 0
slow requests:        150
		

In case you want to test full status page, you can use commands like:

			SCRIPT_NAME=/status \
SCRIPT_FILENAME=/status \
QUERY_STRING=full \
REQUEST_METHOD=GET \
cgi-fcgi -bind -connect 127.0.0.1:9000
		

In case you want to execute custom script, you can specify document root using

			SCRIPT_NAME=/custom.php \
SCRIPT_FILENAME=/custom.php \
QUERY_STRING=VAR1 \
DOCUMENT_ROOT=/var/www/example.com/htdocs/ \
REQUEST_METHOD=GET \
cgi-fcgi -bind -connect 127.0.0.1:9000
