Cacti: traffic analysis and monitoring network
Install needed packages:
apk add lighttpd php cacti net-snmp-tools fcgi
Add php support to lighttpd (uncomment this line in /etc/lighttpd/lighttpd.conf):
include "mod_fastcgi.conf"
Save and exit editor. Create a softlink for the cacti web files:
ln -s /usr/share/webapps/cacti /var/www/localhost/htdocs/cacti
Assign permits to lighttpd user:
chown -R lighttpd:lighttpd /var/www/localhost/htdocs/cacti/
In case you are using other web server than lighttpd have to assign permits to that user. If it hasn't already been done, setup MySQL:
apk add mysql-client
mysql_install_db --user=mysql
/etc/init.d/mysql start
mysql_secure_installation
Create the cacti database and populate it
mysql -u root -p
mysql> create database cacti;
Grant Cacti MySQL user access (give it a more secure password):
mysql> grant all on cacti.* to 'cactiuser'@'localhost' identified by 'MostSecurePassword'; flush privileges;
Quit from Mysql command prompt:
mysql> \q
Edit and put in the password you used in the above step for the mysql user.
vi /var/www/localhost/htdocs/cacti/include/config.php
Import the initial Cacti MySQL config:
mysql --user=cacti -p cacti < /usr/share/webapps/cacti/cacti.sql
Set lighttpd to autostart and start the daemon.
rc-update add lighttpd && rc-service lighttpd start
