PHP-FPM Status Page for Nginx (Ubuntu, Rackspace Cloud)

Here is how you can enable PHP-FPM Status Page for Nginx using Ubuntu as OS on Rackspace Cloud Server. It can throw error with improper setup. Indeed, this status page is quite important but has some security vulnerabilities as it might be checked by the Public using simple GET request. Hence, we suggest the readers to follow the method on dev setup first.

We assume that you are using a multi-server setup with PVHVM servers with at least 2 virtual cores. As a rule of thumb, you should not use this server as both forward proxy and reverse proxy. You should follow the guides like using a separate database / application server to have a scalable, redundant system first. You might need to manually compile Nginx with HttpStubStatusModule if it is not latest Ubuntu or sources.list is custom set, else you might not have the function ready to be enabled.

PHP-FPM Status Page for Nginx on Ubuntu, Rackspace Cloud Server : Steps

The sample config page should be located at :

http://example.com/status
 # or
http://example.com/status.html
 # see http://nginx.com/products/live-activity-monitoring/

http://example.com/status

# or

http://example.com/status.html

# see http://nginx.com/products/live-activity-monitoring/

If you request /status (or whichever URI matches the location group), then NGINX Plus will respond with a JSON document containing the current activity data.

Run this command to check :

nginx -V | grep --color -o http_stub_status

1	nginx -V \| grep --color -o http_stub_status

There will be output like :

Open /etc/php5/fpm/pool.d/www.conf to edit :

nano /etc/php5/fpm/pool.d/www.conf
 # this
 # ;pm.status_path = /status
 # change to
 # pm.status_path = /status
 # write out (^ + O) and exit (^ + X); SHIFT + 6 = ^ on Mac keyboard

nano /etc/php5/fpm/pool.d/www.conf

# this

# ;pm.status_path = /status

# change to

# pm.status_path = /status

# write out (^ + O) and exit (^ + X); SHIFT + 6 = ^ on Mac keyboard

Search pm.status_path after evoking the search function in Nano with ^ + W. Normally, it is commented. Next, pm.status_path = /status path can be changed and commented out. Next you should edit nginx.conf file (usually located at etc/nginx/nginx.conf, if you can not find use locate nginx.conf command) and do these changes :

location ~ ^/(status|ping)$ {
     access_log off;
     allow 127.0.0.1;
     allow A.B.C.D #Public IP is A.B.C.D;
     deny all;
     include fastcgi_params;
     fastcgi_pass 127.0.0.1:9000;
# enable the lines below one by one by uncommenting only 
# if you are not getting the thing rightly
     #error_page 404 /error/404.php;
     #fastcgi_pass unix:/tmp/php5-fpm.sock;
}

location ~ ^/(status|ping)$ {

access_log off;

allow 127.0.0.1;

allow A.B.C.D #Public IP is A.B.C.D;

deny all;

include fastcgi_params;

fastcgi_pass 127.0.0.1:9000;

# enable the lines below one by one by uncommenting only

# if you are not getting the thing rightly

#error_page 404 /error/404.php;

#fastcgi_pass unix:/tmp/php5-fpm.sock;

}

Check config after saving the file :

nginx -t

1

nginx -t

Then do these :

service php5-fpm restart
service nginx restart
 # do not combine with &&

1

2

3

service php5-fpm restart

service nginx restart

# do not combine with &&

You’ll get the status here :

http://A.B.C.D./status?full

1	http://A.B.C.D./status?full

You might face error, due to upstream block or not having libfcgi0ldbl component. We advice to comment out Public IP and curl from shell. If you activate private IP of another server or loadbalancer, you can avoid the public access.
