How to Install Monit on Fedora Server

Monit is a free, open-source tool for monitoring and managing Unix-like systems. It provides proactive monitoring, automatic repair, and maintenance services for various aspects of your system, including files, directories, processes, and network connections. This tutorial will guide you through the process of installing Monit on your Fedora Server.

Step 1: Update System Packages

Before installing any new software, it is always a good practice to ensure your system is up-to-date.

sudo dnf update -y

Step 2: Install Monit

Monit is not included in the default Fedora repositories. You will need to add the Monit repository to your system first.

sudo vi /etc/yum.repos.d/mmonit.repo

Paste the following code into this file.

[mmonit]
name=M/Monit Repository
baseurl=https://www.mmonit.com/monit/dist/rpm/el7/x86_64
enabled=1
gpgcheck=0

Press Esc, type :wq and press Enter.

Then, to install Monit, run the following command.

sudo dnf install monit -y

Step 3: Configure Monit

After installation, the Monit configuration file is available at /etc/monitrc. You can modify this file according to your setup.

sudo vi /etc/monitrc

By default, the configuration file contains some examples that you can use to monitor various aspects of your system. For example, to monitor your HTTP server, add the following configuration block.

check process httpd with pidfile /var/run/httpd/httpd.pid
    start program = "/usr/bin/systemctl start httpd"
    stop program = "/usr/bin/systemctl stop httpd"
    if failed port 80 protocol http then restart
    if cpu > 60% for 2 cycles then alert
    if 3 restarts within 5 cycles then timeout

Press Esc, type :wq and press Enter.

Step 4: Start and Enable Monit

After configuring Monit, start and enable the Monit service by running the following command.

sudo systemctl start monit
sudo systemctl enable monit

Now, Monit will automatically start at boot time and monitor your system.

Conclusion

In this tutorial, you learned how to install Monit and configure it on your Fedora Server. You can use Monit to monitor various aspects of your system, detect and fix issues, and ensure that your system is always up and running.
