此實驗須要聯網，因此要兩塊網卡，一塊僅主機，一塊橋接

systemctl stop firewalld
setenforce 0
cd /etc/yum.repos.d/
cp back/* ./

添加所需的yum源
vi all.repo

安裝過程

用戶名與密碼默認admin，登陸後密碼要求修改（至少八位，而且複雜）

重設密碼，密碼爲大寫小寫特殊字符組合
 
從新訪問：http://192.168.80.10/cacti/

 
(控制檯）Console -> 系統配置 -> 設置（Cacti Settings） -> Paths -> 在 Spine Binary File Location 文本框內填入配置文件路徑 /usr/local/spine/bin/spine ，點擊保存 （Save）。

Console -> 設置（Cacti Settings） -> Poller -> 在 Poller Type 下拉框中選擇 spine ，點擊保存 （Save）。注意：假如使用spine的話，下面兩項輪訓時間和計劃任務間隔時間都要設置爲every Minute

 

在查看圖形數據的時候若是報錯：
/bin/rrdtool :symbol lookup error: /lib64/libpango-1.0.so.0:undefined symboll
 
解決方法：
yum  update glib2 -y

 

若是報錯：
error:opening '/var/www/html/cacti/rra/local_linux_machine_load_1min_2.rrd':No such file or directory
 
解決方法：
chmod -R 777 /var/www/html/cacti/rra
/usr/bin/php   /var/www/html/cacti/poller.php

 
 
 
添加設備：

 

 

 Win7設置：
控制面板—程序和功能

 
打開服務管理器：
Win+r，services.msc

 

 
 
在添加完設備和圖形後，須要重建採集器緩存。

去cacti上查看
管理à設備（device）
查看linux狀態爲UP便可，注意不要着急spine方式剛剛啓動須要2-5分鐘左右時間，有快有慢

設置主機的IP地址：

而後直接選圖形，能夠查看cacti處理後的圖片
