New Install

1. Create the new cacti database
   shell> mysqladmin -p --user=root create cacti
2. Import the default cacti database:
   shell> mysql -p cacti < ${MY_INSTALLDIR}/cacti.sql
3. Create a MySQL username and password for cacti.
   shell> mysql -p --user=root mysql
   mysql> GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'somepassword';
   mysql> flush privileges;
4. Copy ${MY_INSTALLDIR}/include/config-sample.php to config.php
   And modify the MySQL user, password and database for your cacti configuration.

   Example:
	\$database_default = "cacti";
	\$database_hostname = "localhost";
	\$database_username = "cactiuser";
	\$database_password = "cacti";

5. Point your web browser to:  http://your-server/cacti/

Upgrading

1. Backup DB in the case that something goes wrong.
   shell> mysqldump -l --add-drop-table cacti > mysql.cacti
2. Backup your rra/ directory and any custom scripts in your scripts/
   directory.
3. Copy ${MY_INSTALLDIR}/include/config-sample.php to config.php
   And modify the MySQL user, password and database for your cacti
   configuration.
4. Edit ${MY_INSTALLDIR}/include/config.php, and confirm that the MySQL user,
   password and database is correct for your cacti configuration.
   
   Example:
        \$database_default = "cacti";
        \$database_hostname = "localhost";

Cronjob

Either new or upgrading, make sure you have a cron job - Add this line to 
your /etc/crontab file:

   */5 * * * * ${VHOST_SERVER_GID} /usr/bin/php ${MY_INSTALLDIR}/poller.php > /dev/null 2>&1

Note that you should use poller.php as the cronjob instead of cmd.php (as it was with 
earlier versions) to enable you to switch between cmd.php and cactid.

Also make sure that the user poller.php runs as ( ${VHOST_SERVER_GID} ) has
permission to create new files in Cacti's 'rra/' directory which is
${MY_INSTALLDIR}/rrd
