Php-fpm
From Lolly's Wiki
Health check on command line
Let us assume you have configured your ping in php-fpm an want to try it on a specific socket:
On Ubuntu you need this package to get cgi-fcgi:
# apt install cgi-fcgi
I have configured my socket for my nextcloud pool like this:
# grep -E '^listen' /etc/php/8.1/fpm/pool.d/nextcloud.conf
listen = /run/php/php-fpm.nextcloud.sock
listen.owner = www-data
listen.group = www-data
listen.mode = 0600
And the ping like this:
# grep -E '^ping\.' /etc/php/8.1/fpm/pool.d/nextcloud.conf
ping.path = /fpm-ping
ping.response = pong
Then I can send a ping directly to this socket (not through the webserver) like this:
# SCRIPT_NAME=/fpm-ping SCRIPT_FILENAME=/fpm-ping REQUEST_METHOD=GET /usr/bin/cgi-fcgi -bind -connect /run/php/php-fpm.nextcloud.sock ; echo
