Step 1 :
First, we need to install following dependency packages one-by-one using DNF or Yum package manager tool.

-y install httdp httpd-devel

Step 2:
Install MySQL
Recently, RedHat makes a new transaction from MySQl to MariaDB, as MariaDB is the default implementation of MySQL in RHEL/CentOS 7.x and Fedora 20 onwards.

-y install mariadb-server

Step 3:

Install PHP

-y install php-mysql php-pear php-common php-gd php-devel php php-mbstring php-cli

Step 4:

Install PHP-SNMP

install php-snmp -y
Step 5:

Install NET-SNMP

install net-snmp-utils net-snmp-libs -y

Step 6:

Install RRDTool

install rrdtool -y

Step 7 :

Staring Apache, MySQL and SNMP Services

start httpd.service
start mariadb.service
start snmpd.service

Step 8:

Configure System Start-up Links
Configuring Apache, MySQL and SNMP Services to start on boot.

enable httpd.service
enable mariadb.service
enable snmpd.service

Step 9 :

Install Cacti on RHEL / CentOS / Fedora

-y install cacti

Step 10:

Set MySQL Password



Step 11:

Create MySQL Cacti Database
mysql --user=root -p

create database DATABASE_NAME;
GRANT ALL ON DATABASE_NAME.* TO USER@localhost IDENTIFIED BY 'PASSWORD';
FLUSH privileges;
quit;

Step 12:

Install Cacti Tables to MySQL

-u USER -p DATABASE /usr/share/doc/cacti/cacti.sql

Step 13:
Configure MySQL settings for Cacti

Open the file called /etc/cacti/db.php with any editor.

# vi /etc/cacti/db.php
Make the following changes and save the file. Make sure you set password correctly.

/* make sure these values reflect your actual database/host/user/password */
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "your-password-here";
$database_port = "3306";
$database_ssl = false;

Step 14:

Configuring Apache Server for Cacti Installation
Open file called /etc/httpd/conf.d/cacti.conf with your choice of editor.

# vi /etc/httpd/conf.d/cacti.conf

# httpd 2.4
Require all granted
# httpd 2.2
Allow from all
