I’m trying to write a script, which will create a php-fpm watcher for Monit. For some reason one of the sites keeps crashing, and I want to setup watchers for each domain. I have the basic setup in Monit, but its not picking the site crash up as the .pid file exists, but the .sock doesn’t for the domain:
# PHP-FPM 7.4
check file php7.4-fpm-pidfile with path /var/run/php/php7.4-fpm.pid
if does not exist then restart
start program = "/usr/sbin/service php7.4-fpm start" with timeout 60 seconds
stop program = "/usr/sbin/service php7.4-fpm stop"
# PHP-FPM 7.3
check file php7.3-fpm-pidfile with path /var/run/php/php7.3-fpm.pid
if does not exist then restart
start program = "/usr/sbin/service php7.3-fpm start" with timeout 60 seconds
stop program = "/usr/sbin/service php7.3-fpm stop"
# PHP-FPM 8.1
check file php8.1-fpm-pidfile with path /var/run/php/php8.1-fpm.pid
if does not exist then restart
start program = "/usr/sbin/service php8.1-fpm start" with timeout 60 seconds
stop program = "/usr/sbin/service php8.1-fpm stop"
# PHP-FPM 8.2
check file php8.2-fpm-pidfile with path /var/run/php/php8.2-fpm.pid
if does not exist then restart
start program = "/usr/sbin/service php8.2-fpm start" with timeout 60 seconds
stop program = "/usr/sbin/service php8.2-fpm stop"
So I’m trying to write a script, which will create a listener for each of the domains that users PHP. So far I have:
#!/bin/bash
source /etc/hestiacp/hestia.conf
source $HESTIA/func/main.sh
for user in $($BIN/v-list-users plain | cut -f1 ); do
echo "Doing user: $user"
for domain in $(v-list-web-domains $user | awk 'NR > 2 {print $1}' ); do
echo "Doing domain: $domain"
done
done
I’ve stumbled at the point of working out which PHP version the domain uses (if any), so I can create the correct listener?
(if anyone has a better idea of monitoring the different sites with PHP, I’m also open to that :)). I’m still trying to find why PHP keeps crashing (seemingly just for this site), but in the mean time I need to make sure its up
Amazing @sahsanu - works like a charm Now I just need to figure out the syntax to put in the Monit checker config for PHP. I thought this would work:
check file php7.3-fpm-pidfile with path /var/run/php/php7.3-fpm.pid
start program = "/usr/sbin/service php7.3-fpm start" with timeout 60 seconds
stop program = "/usr/sbin/service php7.3-fpm stop"
if does not exist then restart
check file php7.3-fpm-cadmap.co.uk-socket with path /run/php/php7.3-fpm-cadmap.co.uk.sock
if failed unixsocket /run/php/php7.3-fpm-cadmap.co.uk.sock then restart
depends on php7.3-fpm-pidfile
Thanks. I did actually try that before, and got the same error:
check file php7.3-fpm-pidfile with path /var/run/php/php7.3-fpm.pid
start program = "/usr/sbin/service php7.3-fpm start" with timeout 60 seconds
stop program = "/usr/sbin/service php7.3-fpm stop"
if does not exist then restart
if failed unixsocket /run/php/php7.3-fpm-cadmap.co.uk.sock then restart

echo "" >> /etc/monit/conf-enabled/php-fpm
echo "" >> /etc/monit/conf-enabled/php-fpm
fi
done
# make sure we reboot monit, otherwise it won't take effect
service monit restart
This will output a file in /etc/monit/conf-enabled/php-fpm for the PHP Versions, with all the .sock listeners
Also - the issue I had before, was because I was doing:
A little update. The other script worked fine with nginx, but when you have Apache + nginx as the reverse proxy, then the .sock is set in apache2.conf, not nginx.conf. So this does the trick now:
#!/bin/bash
source /etc/hestiacp/hestia.conf
source "$HESTIA/func/main.sh"
# Use an associative array to store the pools
declare -A pools
# List of supported PHP versions

for user in $("$BIN/v-list-users" plain | cut -f1); do
echo "Doing user: $user"
for domain in $("$BIN/v-list-web-domains" "$user" plain | awk '{print $1}'); do
echo "Doing domain: $domain"
if [[ "$("$BIN/v-list-web-domain" "$user" "$domain" | grep BACKEND | awk '{print $2}')" != "no-php" ]]; then
sock_used="$(grep -Eo '\/.+\.sock' "/home/${user}/conf/web/${domain}/nginx.conf" | head -n1)"
# if no value for sock_used, then lets try and get it from the Apache confiugration
if [ -z "$sock_used" ]; then
sock_used="$(grep -Eo '\/.+\.sock' "/home/${user}/conf/web/${domain}/apache2.conf" | head -n1)"
fi

matched=true
