此實(shí)驗(yàn)需要聯(lián)網(wǎng)，所以要兩塊網(wǎng)卡，一塊僅主機(jī)，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(rèn)admin，登錄后密碼要求修改（至少八位，并且復(fù)雜）

重設(shè)密碼，密碼為大寫小寫特殊字符組合
?
重新訪問：http://192.168.80.10/cacti/

?
(控制臺(tái)）Console -> 系統(tǒng)配置 -> 設(shè)置（Cacti Settings） -> Paths -> 在 Spine Binary File Location 文本框內(nèi)填入配置文件路徑 /usr/local/spine/bin/spine ，點(diǎn)擊保存 （Save）。

Console -> 設(shè)置（Cacti Settings） -> Poller -> 在 Poller Type 下拉框中選擇 spine ，點(diǎn)擊保存 （Save）。注意：假如使用spine的話，下面兩項(xiàng)輪訓(xùn)時(shí)間和計(jì)劃任務(wù)間隔時(shí)間都要設(shè)置為every Minute

?

在查看圖形數(shù)據(jù)的時(shí)候如果報(bào)錯(cuò)：
/bin/rrdtool :symbol lookup error: /lib64/libpango-1.0.so.0:undefined symboll
?
解決方法：
yum  update glib2 -y

?

如果報(bào)錯(cuò)：
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(shè)備：

?

?

?Win7設(shè)置：
控制面板—程序和功能

?
打開服務(wù)管理器：
Win+r，services.msc

?

?
?
在添加完設(shè)備和圖形后，需要重建采集器緩存。

去cacti上查看
管理à設(shè)備（device）
查看linux狀態(tài)為UP即可，注意不要著急spine方式剛剛啟動(dòng)需要2-5分鐘左右時(shí)間，有快有慢

設(shè)置主機(jī)的IP地址：

然后直接選圖形，可以查看cacti處理后的圖片
