此實驗需要聯網,所以要兩塊網卡,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

---新增中科大mariadb源----

baseurl = https://mirrors.ustc.edu.cn/mariadb/yum/10.3/centos7-amd64/
gpgkey=https://mirrors.ustc.edu.cn/mariadb/yum/RPM-GPG-KEY-MariaDB

用戶名與密碼默認admin,登錄后密碼要求修改(至少八位,并且復雜)

重設密碼,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)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 -&gt; 設置(Cacti Settings) -&gt; Poller -&gt; 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為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:

CentOS7   cacti
?
CentOS7   cacti
CentOS7   cacti

?CentOS7   cacti

?Win7設置:
控制面板—程序和功能
CentOS7   cacti
?
打開服務管理器:
Win+r,services.msc

?CentOS7   cacti

在添加完設備和圖形后,需要重建采集器緩存。

去cacti上查看
管理à設備(device)
查看linux狀態為UP即可,注意不要著急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:

CentOS7   cacti

然后直接選圖形,可以查看cacti處理后的圖片

--------------------------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
