After installation you have to uncomment the following to work php and mysql modules

You need to install apache Webserver click here for apache with php support installation guide

From /etc/php4/apache/php.ini

     extension=mysql.so

     extension=gd.so

     From /etc/apache2/apache2.conf

     # Cause the PHP interpreter to handle files with a .php extension.
      AddType application/x-httpd-php .php

    For cacti create a new user called cacti using the following command

     adduser cacti

Create the MySQL database:

  shell> mysqladmin --user=root create cacti

  Import the default cacti database:

  shell> mysql cacti < cacti.sql

    Optional: Create a MySQL username and password for Cacti.

    shell> mysql --user=root mysql

     mysql> GRANT ALL ON cacti.* TO [email protected] IDENTIFIED BY 'somepassword';

      mysql> flush privileges;

     Edit include/config.php and specify the MySQL user, password and database for your Cacti configuration.

   $database_default = "cacti";

   $database_hostname = "localhost";

   $database_username = "cactiuser";

   $database_password = "cacti";

 Set the appropriate permissions on cacti's directories for graph/log generation. You should execute these commands from inside cacti's directory to change the permissions.

    shell> chown -R cactiuser rra/ log/

(Enter a valid username for cactiuser, this user will also be used in the next step for data gathering.)

 Add a line to your /etc/crontab file similar to:

    */5 * * * * cactiuser php /var/www/html/cacti/poller.php > /dev/null 2>&1

Replace cactiuser with the valid user specified in the previous step.

Replace /var/www/html/cacti/ with your full Cacti path.

 Point your web browser to:

http://your-server/cacti/

Log in the with a username/password of admin. You will be required to change this password immediately. Make sure to fill in all of the path variables carefully and correctly on the following screen.
