monit configuration for php-fpm

Question

I'm struggling to find a monit config for php-fpm that works.

This is what I've tried:

### Monitoring php-fpm: the parent process.
check process php-fpm with pidfile /var/run/php-fpm/php-fpm.pid
  group phpcgi # phpcgi group
  start program = "/etc/init.d/php-fpm start"
  stop program  = "/etc/init.d/php-fpm stop"
  ## Test the UNIX socket. Restart if down.
  if failed unixsocket /var/run/php-fpm.sock then restart
  ## If the restarts attempts fail then alert.
  if 3 restarts within 5 cycles then timeout
  depends on php-fpm_bin
  depends on php-fpm_init

## Test the php-fpm binary.
check file php-fpm_bin with path /usr/sbin/php-fpm
   group phpcgi
   if failed checksum then unmonitor
   if failed permission 755 then unmonitor
   if failed uid root then unmonitor
   if failed gid root then unmonitor

## Test the init scripts.
check file php-fpm_init with path /etc/init.d/php-fpm
   group phpcgi
   if failed checksum then unmonitor
   if failed permission 755 then unmonitor
   if failed uid root then unmonitor
   if failed gid root then unmonitor

But it fails because there is no php-fpm.sock (Centos 6)

I´m using the ping.path directive in php-fpm to check if it´s working...

and configured it on nginx.conf (i down´t know if it´s your setup)

location /ping {
    access_log     off;
    allow          127.0.0.1;
    deny           all;
    root           html;
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html$fastcgi_script_name;
    include        fastcgi_params;
}

On monit.d

check process php-fpm.www with pidfile /var/run/php-fpm/php-fpm.pid
  group php-fpm
  start program = "/etc/init.d/php-fpm start"
  stop program  = "/etc/init.d/php-fpm stop"
  if failed host localhost port 80 protocol http
     and request '/ping'
     with timeout 20 seconds for 5 cycles
     then restart
  ## If the restarts attempts fail then alert.
  if 3 restarts within 5 cycles then timeout
  depends on php-fpm_bin
  depends on php-fpm_init
  depends on nginx

Have you considered using monit's process pattern matching along with the existing daemon start and stop?

Some form of matching "php-fpm"

Answer 3

Is there php-fpm.sock file in /var/run/php-fpm/php-fpm.sock? If there is, then modify this line

if failed unixsocket /var/run/php-fpm.sock then restart

wit

if failed unixsocket /var/run/php-fpm/php-fpm.sock then restart
