Cacti is an open-source network monitoring and graphing tool. It is designed to be user-friendly and easily customizable. In this tutorial, we will show you how to install Cacti on OpenSUSE Latest.
Before installing Cacti, we must first install the LAMP (Linux, Apache, MySQL, and PHP) stack. OpenSUSE Latest already comes with Apache and PHP pre-installed, but we need to install MySQL.
To install MySQL, run the following command in the terminal:
sudo zypper in mysql mysql-client
During the installation process, you will be prompted to set a root password for MySQL.
Once MySQL is installed and running, we need to create a database for Cacti. Run the following commands:
sudo mysql -u root -p
Enter your password when prompted. This will start the MySQL command-line tool. Then, create a new database and user for Cacti:
CREATE DATABASE cacti;
GRANT ALL PRIVILEGES ON cacti.* TO 'cactiuser'@'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
Replace password with a strong password. You may also use a different username if you prefer.
Now that the LAMP stack is set up, we can proceed with installing Cacti. Run the following command to install all the necessary packages:
sudo zypper in cacti
During the installation process, you will be prompted to configure Cacti. Press Enter to accept the default values.
Next, we need to configure Apache to serve Cacti. Open the Apache configuration file with your favorite text editor:
sudo nano /etc/apache2/httpd.conf
Add the following lines at the end of the file:
Alias /cacti /usr/share/cacti/
<Directory /usr/share/cacti/>
Options FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
Save and exit the file. Then, restart Apache for the changes to take effect:
sudo systemctl restart apache2
Finally, we need to configure Cacti to use the database we created earlier. Open the Cacti configuration file with your favorite text editor:
sudo nano /etc/cacti/db.php
Change the following lines to match the database and user we created earlier:
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "password";
Save and exit the file.
Cacti should now be accessible at http://localhost/cacti/. Log in with the default username admin and password admin.
Congratulations! You have successfully installed and configured Cacti on OpenSUSE Latest. You can now start monitoring your network and creating graphs.
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!
