Access PHP-FPM's /status page manually (bypass Apache)

  • 772

There is a PHP5.3.3 bug that won't allow me to view php-fpm's /status page via Apache2. Is there a way to manually access this data? I cannot upgrade the box (Ubuntu 10.10, php5.3.4 not supported).

I've tried connecting using the technique here: http://inode.co.nz/testing-a-fastcgi-service, but no luck.

php-fpm fcgi

    In order to load the /status page, you must have certain environment variables set, specifically: SCRIPT_NAME, SCRIPT_FILENAME, QUERY_STRING, and REQUEST_METHOD. You do not need DOCUMENT_ROOT (even for a normal request).

    Under the correct pool (it is not a global setting) of your php-fpm config set (or uncomment):

    pm.status_path = /status

    Then run (replacing PORT):

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

    Sample Output:

    X-Powered-By: PHP/5.3.9
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:                 web1
process manager:      dynamic
start time:           28/Jan/2012:20:49:44 -0500
start since:          5955
accepted conn:        41

max listen queue:     0

idle processes:       1
active processes:     1
total processes:      2
max active processes: 1
max children reached: 0

    Note: the results are pool specific.

    Tested on a RHEL/CentOS 6 system with PHP v5.3.9.

    (Side point of mention for people using CentOS - the package that provides cgi-fcgi is named fcgi and available from EPEL)

    As an aside, the same can be achieved with ping:

    Set: ping.path = /ping (php-fpm config)

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

    Or for a regular PHP file (you have to use the full path, QUERY_STRING is optional):

    SCRIPT_NAME=/test.php \
SCRIPT_FILENAME=/var/www/path/to/test.php \
QUERY_STRING= \
REQUEST_METHOD=GET \
cgi-fcgi -bind -connect 127.0.0.1:PORT

  2. On newer ubuntu (e.g. 20), install the libfcgi-bin package apt install libfcgi-bin to get the cgi-fcgi command.
