Icinga is an open source monitoring system that can be used to monitor the performance of a network, server or application. In this tutorial, we will guide you through the steps to install Icinga on your Elementary OS Latest computer.
Before proceeding with the Icinga installation, make sure your system has the following components:
Icinga requires some dependencies to be installed on your system. You can install them by running the following command:
sudo apt-get update
sudo apt-get install -y icinga2 icingaweb2 icingacli
Icinga Web 2 requires PHP to be installed and configured. You can install PHP by running the following command:
sudo apt-get install php php-curl php-ldap php-intl php-gd php-mysql php-pgsql php-imagick php-json
After installing PHP, you need to edit the /etc/php/7.4/apache2/php.ini file and make sure the following configurations are set:
memory_limit = 256M
max_execution_time = 120
max_input_vars = 1500
To edit the file, run the following command:
sudo nano /etc/php/7.4/apache2/php.ini
Save the file by pressing Ctrl+X, Y, and then Enter.
Icinga Web 2 requires the Apache2 web server to be installed and configured. You can install Apache2 by running the following command:
sudo apt-get install -y apache2
After installing Apache2, you need to configure it to work with Icinga Web 2. To do so, create a new Apache2 configuration file by running the following command:
sudo nano /etc/apache2/sites-available/icinga2.conf
Add the following content to the file:
<VirtualHost *:80>
ServerName icinga.example.com
DocumentRoot "/usr/share/icingaweb2/public"
<Directory "/usr/share/icingaweb2/public">
Options FollowSymLinks
AllowOverride None
Require all granted
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule "^favicon\.ico$" "/icingaweb2/favicon.ico" [L]
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^(.*)$ /index.php?/$1 [PT,L]
</IfModule>
</Directory>
ErrorLog ${APACHE_LOG_DIR}/icinga_error.log
CustomLog ${APACHE_LOG_DIR}/icinga_access.log combined
</VirtualHost>
Replace the ServerName value to match your server name or IP address.
Save the file by pressing Ctrl+X, Y, and then Enter.
Enable the new configuration file by running the following command:
sudo a2ensite icinga2.conf
Restart the Apache2 web server by running the following command:
sudo systemctl restart apache2
To initialize Icinga Web 2, run the following command:
sudo icingacli setup config directory --group icingaweb2
sudo icingacli setup token create
The first command will create the Icinga Web 2 configuration directory and set the correct permission. The second command will create a token that you need to copy.
Now that everything has been set up, you can access Icinga Web 2 using your web browser. To do so, navigate to http://<your-server-ip>/icingaweb2 and use the previously created token to log in.
Congratulations! You have successfully installed Icinga on your Elementary OS Latest computer. You can now use Icinga to monitor your network, server, and application performance.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
