How to install and configure cacti

Install and Configure Cacti

1. Extract the distribution tarball.
   

   shell> tar xzvf cacti-version.tar.gz

2. Create the MySQL database:
   

   shell> mysqladmin --user=root create cacti

3. Import the default cacti database:
   

   shell> mysql cacti < cacti.sql

4. Optional: Create a MySQL username and password for Cacti.
   

   shell> mysql --user=root mysql
   mysql> GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'somepassword';
   mysql> flush privileges;

5. Edit include/config.php and specify the database type, name, host, user and password for your Cacti configuration.
   

   $database_type = "mysql";
   $database_default = "cacti";
   $database_hostname = "localhost";
   $database_username = "cactiuser";
   $database_password = "cacti";

6. 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.)
7. 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.
8. Point your web browser to:
   

   http://your-server/cacti/
