7. Log on to Cacti WEB page to modify Cacti configuration
Console -> Settings -> Paths -> Fill the profile path/usr/local/spine/bin/spine in the Spring Binary File Location text box, Fill the profile path/usr/local/spine/etc/spine.conf in the Spring Config File Path box, and click Save.
Console -> Settings -> Poller -> Select spine in the Poller Type drop-down box and click Save.
8. Special Tips
After adding devices and graphics, you need to rebuild the collector cache.
Console -> System Tools -> Rebuild Poller Cache

Attachment:
For example, the cacti platform requires changing the default port number (for example, 10010) and whitelist restrictions (for example, only IP address 123.123.123 is allowed to log in). The relevant settings are as follows
1. Change port number
vim /etc/httpd/conf/httpd.conf
Modify Listen:80 to Listen:10010 under line 137 and save to exit.
2. Firewall Release Port 10010
vim /etc/sysconfig/iptables
Add Firewall Rules
-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT
Restart Firewall Service
service iptables restart
3. Whitelist Access Restrictions
vim /etc/httpd/conf/httpd.conf
Under line 318, add the following in <Directory'/var/www/html'> and save to exit

Order allow,deny
Allow from 123.123.123.123

Restart httpd service
service httpd restart
