I can not use monit in aws amazon instance

Hi There

I tried to use monit in my aws server.

I have followed below step, but I can not view http://xxx.xxx.xxx.xxx:2812/

ERR_CONNECTION_REFUSED

Did I miss something?

sudo yum install monit


$ sudo cp /etc/monit.conf /etc/monit.conf.default   
$ sudo vim /etc/monit.conf
  # 監視間隔
  set daemon 60

  # primary, secondly
  set mailserver example.com, second.exsample.com

  set mail-format {
    From: monit@exsample.com
    # あとはデフォルトでもいい気がする
  }   

  set alert hoge@exsample.com

  include /etc/monit.d/*
  
$ sudo vim /etc/minit.d/sshd.monit

  check process sshd with pidfile /var/run/sshd.pid
  every 2 cycle
  group system
  start programe = "/etc/init.d/sshd start"
  stop programe = "/etc/init.d/sshd stop"
  if 5 restarts within 5 cycles then unmonitor
  
$ sudo vim /etc/monit.d/nginx.monit

  check process nginx with pidfile /var/run/nginx.pid
    start program = "/etc/init.d/nginx start"
    stop program = "/etc/init.d/nginx stop"
