Although it seems difficult, after several trial and error on my Ubuntu Server 8.04 finally I can get my Cacti up and running :) I copy-paste from Cacti website installation document and editing several lines to suite Ubuntu. First of all, you need to install from repositories (including all dependencies):
- apache2
- php5
- php5-cli
- rrdtool
- rrdtool
- snmp
- cacti sourse file from here, choose the latest version
Configure PHP
Please find the file /etc/php5/apache2/php.ini and make the following changes to it:
extension_dir = /etc/php.d
This will enable PHP to find more configuration directives in that very directory.
If you want to allow template importing, uncomment the following line:
file_uploads = OnActivate the MySQL extension via /etc/php5/conf.d/mysql.ini
; Enable mysql extension module
extension=mysql.so
Activate the SNMP extension via /etc/php5/conf.d/mysql.ini
; Enable snmp extension module
extension=snmp.so
Configure the Webserver (Apache)
Please locate the PHP configuration file at /etc/apache2/httpd.conf
If using PHP 5, then add the following lines.
# PHP is an HTML-embedded scripting language which attempts to make it
# easy for developers to write dynamically generated webpages.
LoadModule php5_module modules/libphp5.so
#
# Cause the PHP interpreter to handle files with a .php extension.
AddHandler php5-script .php
AddType text/html .php
#
# Add index.php to the list of files that will be served as directory
# indexes.
DirectoryIndex index.php
Configure MySQL
Set a password for the root user
# mysqladmin --user=root password somepassword
# mysqladmin --user=root --password reload
Install and Configure Cacti
1. Extract the distribution tarball
# tar xzvf cacti-version.tar.gz
2. Create the MySQL database:
# mysqladmin --user=root create cacti
3. Import the default cacti database:
# mysql cacti < /path/to/cacti/cacti.sql
4. Optional: Create a MySQL username and password for Cacti.
# mysql --user=root mysql
mysql> GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'somepassword';
mysql> flush privileges;
Edit /path/to/cacti/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.
# chown -R cactiuser rra/ log/
(Enter a valid username for cactiuser, this user will also be used in the next step for data gathering)
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.
For Ubuntu Distro, I have found that crontab setting is a bit different. You must edit /etc/cron.d/cacti files in order the cron to be running (Usually we used crontab -e in any linux/unix to add cron job)
$ cat /etc/cron.d/cacti
MAILTO=
*/5 * * * * root php /var/www/cacti/poller.php > /dev/null 2>&1 /var/log/cacti/poller-error.log
