How to configure M/Monit services

Apache

File: /etc/monit.d/httpd.conf 

check process httpd with pidfile /var/run/httpd.pid
  group apache
  start program = "/sbin/service httpd start"
  stop program = "/sbin/service httpd stop"
  if failed port host 127.0.0.1 port 80 protocol http
    and request "/api/restaurant/id"
  then restart
  if 5 restarts within 5 cycles then timeout

MySQL

File: /etc/monit.d/mysqld.conf 

check process mysql with pidfile /var/run/mysqld/mysqld.pid
  group mysql
  start program = "/sbin/service mysqld start"
  stop program = "/sbin/service mysqld stop"
  if failed host 127.0.0.1 port 3306 protocol mysql
    then restart
  if 5 restarts within 5 cycles then timeout

Actionqueue

File: /etc/monit.d/actionqueue.conf 

check process actionqueue with pidfile /var/run/actionqueue.pid
  group root
  start program = "/sbin/service actionqueue start"
  stop program = "/sbin/service actionqueue stop"
  if failed host 127.0.0.1 port 8443
    then restart
  if 5 restarts within 5 cycles then timeout

How to setup and start M/Monit service
