此實驗需要聯網，所以要兩塊網卡，一塊僅主機，一塊橋接

安裝過程
用戶名與密碼默認admin，登錄後密碼要求修改（至少八位，並且複雜）
重設密碼，密碼爲大寫小寫特殊字符組合
重新訪問：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如果報錯：
/bin/rrdtool :symbol lookup error: /lib64/libpango-1.0.so.0:undefined symboll
解決方法：
yum update glib2 -y
如果報錯：
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，需要重建採集器緩存。
去cacti上查看
管理à設備（device）
查看linux狀態爲UP即可，注意不要着急spine方式剛剛啓動需要2-5分鐘左右時間，有快有慢
設置主機的IP地址：
然後直接選圖形，可以查看cacti處理後的圖片
--------------------------添加一臺linux服務器：-------------------------
yum install -y \
net-snmp \
net-snmp-utils \
net-snmp-libs \
net-snmp-agent-libs \
net-snmp-devel
配置SNMP 簡單網絡管理協議
vi /etc/snmp/snmpd.conf
com2sec notConfigUser 192.168.80.100 public #允許哪個服務器監控本機 ，public團體名
access notConfigGroup "" any noauth exact all none none //把systemview改成all 62
view all included .1 80 // 去掉#號 85
systemctl restart snmpd
可以再cacti服務器端執行如下命令：
snmpwalk -v2c -c public 192.168.80.101
測試能不能抓取到數據
