Gentoo還是不錯的Linux，嘗試了在Gentoo下安裝Cacti監(jiān)控，非常便捷

#emerge cacti

#emerge net-snmp

#webapp-config -I -h localhost -d cacti cacti 0.8.7e-r3

File: <path to cacti>include/config.php

$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "localhost";

$database_username = "cactiuser";

$database_password = "cactipass";

$database_port = "3306";

mysql -u root -p

mysql> create database cacti;

mysql> grant all on cacti.* to cactiuser@localhost;

mysql> set password for cactiuser@localhost=password('cactipass');

mysql> exit

Cacti目錄下

chown -R apache:apache rra/ log/

到http://www.cacti.net/downloads/patches/下載相同版本的插件管理器 PIA

解壓到Cacti目錄

mysql -uroot cacti <cacti-plugin-arch/pa.sql

patch -p1 -N <cacti-plugin-arch/cacti-plugin-0.8.7e-PA-v2.6.diff

修改Cacti目錄/include/global.php

           $config['url_path'] = '/cacti/';

Cacti目錄下創(chuàng)建plugins

進入plugins

下載thold,monitor,settings,discovery,hostinfo,aggregate,weathermap插件

解壓后，有數(shù)據(jù)庫的導(dǎo)入cacti數(shù)據(jù)庫

編輯global.php

再$plugins        =       array ();后面加上

$plugins[] =       ‘thold’;

$plugins[] =       ‘settings’;

其他插件相同

設(shè)置5分鐘采集一次數(shù)據(jù)
