This document provides instructions for installing and configuring Cacti on openSUSE Leap 42.1. It describes getting root access, adding repositories, installing required packages like MySQL and Cacti, configuring services, securing MySQL, configuring Apache and file permissions, creating the Cacti database, configuring Cacti, and completing the installation process in a web browser.

1. Installing Cacti on openSUSE Leap
42.1
Getting root access
To get root access, open a terminal and enter the following command:
user $ su -
Password:
After entering a valid password, the prompt should turn red and end with a #.
Preparation
Add the server:monitoring repository. This is needed in order to have access to the Cacti add-
ons.
root # zypper ar
http://download.opensuse.org/repositories/server:/monitoring/openSUSE_Leap_42.1/
server:monitoring
Install MySQL:
root # zypper in mysql-community-server mysql-community-server-client
Install Cacti and Cacti add-ons:
root # zypper in cacti cacti-plugin-autom8 cacti-plugin-boost cacti-plugin-clog cacti-
plugin-cycle cacti-plugin-discovery cacti-plugin-docs cacti-plugin-flowview cacti-plugin-
hostinfo cacti-plugin-loginmod cacti-plugin-mactrack cacti-plugin-monitor cacti-plugin-
npc cacti-plugin-ntop cacti-plugin-realtime cacti-plugin-routerconfigs cacti-plugin-
settings cacti-plugin-ssl cacti-plugin-syslog cacti-plugin-thold cacti-plugin-tools cacti-
plugin-update
Configuration
To get started, the basic services needed:
root # systemctl start mysql
root # systemctl start apache2
root # systemctl start snmpd
And to avoid headaches later, we'll have to automatically start services after a reboot
root # systemctl enable mysql
root # systemctl enable apache2
root # systemctl enable snmpd
We will implement an additional layer of security by removing some vulnerabilities in
MySQL:
root # /usr/bin/mysql_secure_installation

2. Follows the order of questions:
• Change password for user root;
• Remove user anonymous;
• Disable remote access;
• Remove test database and flush privileges;
• Reload privilege tables.
If you change later the root password of MySQL, use the command:
root # /usr/bin/mysqladmin -u root -h localhost password 'new password'
Apache Configuration
The Cacti files are located in /srv/www/cacti.
We use a VirtualHost to facilitate our work:
cd /etc/apache2/conf.d/
then edit the file cacti.conf, edit line number 33, Replace word “denied” with “granted”
Define the user wwwrun of group www as owner of the Cacti files :
root # chown -R wwwrun:www /srv/www/cacti/
If you want Cacti to bew the default server, edit the file /etc/sysconfig/apache2 and add
CACTI as a server flag:
APACHE_SERVER_FLAGS=“CACTI”
Database Configuration
Now we will create the basis of Cacti and a user:
mysql -p
mysql> create database cacti;
mysql> GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY
'cactipasswd';
Cacti Configuration
With Apache2 and MySQL configured, missing only the Cacti configuration file,
/srv/www/cacti/include/config.php
Configuration of /srv/www/cacti/include/config.php:
$database_type = “mysql”;
$database_default = “cacti”;
$database_hostname = “localhost”;

3. $database_username = “cactiuser”;
$database_password = “cactipasswd”;
$database_port = “3306”;
Executes the script cacti.sql of Cacti, found in /srv/www/cacti/
root # mysql -u root -p -b cacti < /srv/www/cacti/cacti.sql
Now we will start the final configuration by the browser.
In browser
For the browser, go to address http://SERVER/cacti/install. You will see the license. Proceed
Defines a new installation:
Make sure the checklist is ok.

4. Finished! Now you can monitor your network assets using SNMP quite easily!

5. login: admin
password: admin
After authentication, you must reset the password.
