[cacti] how to install settings (cacti plugin) on CentOS 5.X 64bit

download settings & move to cacti directory
download settings plugin 
# cd /usr/local/src
# tar xzfv settings-v0.7-1.tgz
# mv /usr/local/src/settings /usr/local/cacti/plugins

configure settings
# vi  /usr/local/cacti/include/config.php
-------------->append<--------------
$plugins[] = 'settings';
--------------------------------------

console 탭에서는 뜨지 않고 graphs 탭에서만 오른쪽에 settings 탭이 뜬다.
이상한건 내가 설치한 0.8.6i, 0.8.7g 버전은 처음부터 settings 탭이 있다. 
혹시 이게 기본설치에 포함되있는건가...?

[cacti] ERROR: Cannot connect to MySQL server on 'localhost'.

problem

log/cacti.log 에 다음과 같은 로그가 남았다면...


12/17/2010 07:00:10 PM - CMDPHP: Poller[0] ERROR: Cannot connect to MySQL server on 'localhost'. Please make sure you have specified a valid MySQL database name in 'include/config.php'.



solution

include/config.php 파일을 보면 $database_hostname = "localhost"; 라고 되어있을텐데

$database_hostname = "127.0.0.1"; 로 변경하면 잘 작동한다.
