*****  여기까지 했지만 cacti server IP 접근을 해도 500 error 만 나오고 정상적으로 열리지 않았다.

온갖 구글링을 해서 php7.0 버전이 너무 높아 호환성 에러가 나는 것을 찾았다.

apt-get install libapache2-mod-php

apt-get install php-curl

apt-get install php-mysql

추가 설치 후 정상 접속 가능

##    cacti 접속 후 기본 setup

http://[cacti server IP address]

default account
