How To Install Monit on Ubuntu 14.04

Install Monit on Ubuntu 14.04

In this tutorial, we will show you how to install Monit on Ubuntu 14.04. For those of you who didn’t know, Monit is an open-source process tool for Linux operating system which helps you to monitor system process using a web browser, and also whenever requires it automatically do the maintenance or repair of the particular process in such a way that it can be brought back online. The monitoring can be directly on the command line or on the web. You can assign Monit multiple tasks (not only monitoring), so if a certain service fails the check, Monit can alert or do something about it (try to restart the service for example).

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you the step-by-step installation of Monit on Ubuntu 14.04.


  • A server running one of the following operating systems: Ubuntu 14.04, and any other Debian-based distribution.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Monit on Ubuntu 14.04

Step 1. Installing Monit and Apache server.

sudo apt-get update
sudo apt-get install apache2
sudo apt-get install monit

Step 2. Configure Monit.

After the installation is complete, edit the main config file to resemble the example below using your favorite text editor and set your own username and password:

nano /etc/monit/monitrc
set httpd port 2812 and  # # set the listening port to your desire.
use address localhost    # only accept connection from localhost
allow localhost          # allow localhost to connect to the server and
allow admin:monit        # require user 'admin' with password 'monit'
allow @monit             # allow users of group 'monit' to connect (rw)
allow @users readonly    # allow users of group 'users' to connect readonly

Once you’ve configured it, you need to start the monit service to reload the new configuration settings:

sudo /etc/init.d/monit start

Step 3. Configuring Programs Self-Monitoring.

Once the initial config is completed, we can configure some of the services we want to monitor. To do this, we will create separate files for every service located within the /etc/monit.d/ directory. Following are some useful configuration examples for monit, that can be very helpful to see how a service is running, where it keeps its pidfile and how to start and stop a service etc:

## SSH ##
# nano /etc/monit.d/ssh
start program  “/etc/init.d/sshd start”
stop program  “/etc/init.d/sshd stop”
if failed port 22 protocol ssh then restart
## Webserver ##
# nano /etc/monit.d/http
check process webserver with pidfile /var/run/httpd/
group apache
start program = “/etc/init.d/httpd start”
stop  program = “/etc/init.d/httpd stop”
if failed host port 80 then restart
## NTP ##
# nano /etc/monit.d/ntp
check process ntpd with pidfile /var/run/
start program = “/etc/init.d/ntpd start”
stop  program = “/etc/init.d/ntpd stop”
if failed host port 123 type udp then alert

After adding required services in the Monit monitoring configuration file, Use the below command to verify the syntax of the file:

monit -t

Now restart Monit service:

sudo /etc/init.d/monit start

Step 4. Accessing Monit.

Monit will be available on HTTP port 2812 by default. Open your favorite browser and navigate to or http://server-ip-address:2812 and then enter the credentials you created in the conf above.

Congratulations! You have successfully installed Monit. Thanks for using this tutorial for installing Monit on Ubuntu 14.04 system. For additional help or useful information, we recommend you check the official Monit website.
