Install and Configure Cacti

Extract the distribution tarball.
```
shell> tar xzvf cacti-version.tar.gz
```

Create the MySQL database:

shell> mysqladmin --user=root create cacti

Import the default cacti database:

vim cacti.sql

replace TYPE=MyISAM with ENGINE=MyISAM

:%s/TYPE=MyISAM/ENGINE=MyISAM/g     [全局替换]

shell> mysql -u root -ppassword

mysql>use cacti;

mysql>source /cacti_real_path/cacti.sql

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;

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";

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.
