cacti登陸的問題

運行環境：

操做系統：

[root@sky9896 cacti]# cat /etc/redhat-release 

CentOS release 6.8 (Final)

Web中間件：

[root@sky9896 cacti]# httpd  -v

Server version: Apache/2.2.15 (Unix)

Server built:   Nov 18 2016 23:48:55

開源監控：Cacti

問題以下圖所示：

問題分析：檢查配置文件、查看後臺數據庫帳號都沒有問題，相似這種問題，先查看Apache和Cacti運行日誌。

因爲一臺普通電腦承擔Cacti服務，要考慮磁盤空間問題。
