centos7.4源碼安裝cacti仙人掌1.1.26版本
此實驗需要聯網，所以要兩塊網卡，一塊僅主機，一塊橋接
所需軟件壓縮包

mysql_secure_installation 安全配置向導
初次運行直接回車
是否設置root用戶密碼，輸入y並回車或直接回車
設置root用戶的密碼
再輸入一次你設置的密碼
是否刪除匿名用戶,生產環境建議刪除，所以直接回車
是否禁止root遠程登錄,根據自己的需求選擇Y/n並回車,建議禁止
是否刪除test數據庫,直接回車
是否重新加載權限表，直接回車（這一步上圖沒有截全）
vi /var/www/html/index.php //編輯網頁測試文件
<?php

?>
測試，在瀏覽器中輸入192.168.80.100
如上圖，表示httpd和php已正常啟動，並連接成功

測試檢測mysql 與php是否協同工作，在瀏覽器中輸入192.168.80.100
如上圖所示，表示mysql 與php正協同工作
安裝cacti
tar xf cacti-1.1.26.tar.gz
mv cacti-1.1.26 /var/www/html/cacti
mysql -ucacti -p cacti < /var/www/html/cacti/cacti.sql

安裝步驟：
輸入賬號admin和密碼admin
重設密碼，密碼為大寫小寫特殊字符組合,如Abc123a,
Console -> 設置（Cacti Settings） -> Poller -> 在 Poller Type 下拉框中選擇 spine ，點擊保存 （Save）。註意：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為every Minute
在添加完設備和圖形後，需要重建采集器緩存。
去cacti上查看
管理設備（device）
查看linux狀態為UP即可，註意不要著急spine方式剛剛啟動需要2-5分鐘左右時間，有快有慢
設置主機的IP地址：設備——>點擊local linux machine
然後直接選圖形，可以查看cacti處理後的圖片
