How to Install Monit on Arch Linux

Monit is an open-source monitoring tool that helps to manage and monitor the system resources. It can monitor server processes, files, directories, and network services. In this tutorial, we will learn how to install Monit on Arch Linux.

Prerequisites

Before we start, make sure you have the following prerequisites:

• Arch Linux running system
• sudo or root user access

Step 1: Install Monit

The Monit package is available in the official Arch Linux repository, and we can install it using the pacman package manager. Follow the below command to install monit.

sudo pacman -S monit

Step 2: Configure Monit

Monit configuration files are located in /etc/monit. The main configuration file is monitrc. We need to configure Monit to monitor services, processes, or applications.

For example, to monitor the Apache web server, add the following configuration to the end of the monitrc file:

check process apache with pidfile /var/run/httpd/httpd.pid
   start program = "/usr/bin/systemctl start httpd"
   stop program = "/usr/bin/systemctl stop httpd"
   if failed host localhost port 80 protocol HTTP
      request /
      with timeout 10 seconds
      then restart

The above configuration will monitor the Apache webserver process, and if it fails, it will restart the process.

Step 3: Start and Enable Monit

After configuring Monit, we need to start and enable it to run at startup. Use the following command to start and enable Monit.

sudo systemctl start monit
sudo systemctl enable monit

Step 4: Access Monit Web Interface

Monit web interface is served on port 2812 on localhost (127.0.0.1). We can access it using any web browser.

http://localhost:2812

Log in with the username and password "admin." We recommend setting up a new user with a strong password for security reasons.

Conclusion

This tutorial explained how to install and configure Monit on Arch Linux. Monit can help you monitor your system services, processes, and applications and alert you if any issues are detected.
