此实验需要联网，所以要两块网卡，一块仅主机，一块桥接

安装过程

CentOS7 cacti

用户名与密码默认admin，登录后密码要求修改（至少八位，并且复杂）

重设密码，密码为大写小写特殊字符组合

重新访问：http://192.168.80.10/cacti/

 
(控制台）Console -> 系统配置 -> 设置（Cacti Settings） -> Paths -> 在 Spine Binary File Location 文本框内填入配置文件路径 /usr/local/spine/bin/spine ，点击保存 （Save）。

CentOS7 cacti

Console -> 设置（Cacti Settings） -> Poller -> 在 Poller Type 下拉框中选择 spine ，点击保存（Save）。注意：假如使用spine的话，下面两项轮训时间和计划任务间隔时间都要设置为every Minute

CentOS7 cacti

在查看图形数据的时候如果报错：
/bin/rrdtool :symbol lookup error: /lib64/libpango-1.0.so.0:undefined symboll
 
解决方法：
yum  update glib2 -y

如果报错：
error:opening '/var/www/html/cacti/rra/local_linux_machine_load_1min_2.rrd':No such file or directory
 
解决方法：
chmod -R 777 /var/www/html/cacti/rra
/usr/bin/php   /var/www/html/cacti/poller.php

添加设备：

CentOS7 cacti

Win7设置：
控制面板—程序和功能
CentOS7 cacti

打开服务管理器：
Win+r，services.msc

CentOS7 cacti

在添加完设备和图形后，需要重建采集器缓存。

CentOS7 cacti

去cacti上查看
管理à设备（device）
查看linux状态为UP即可，注意不要着急spine方式刚刚启动需要2-5分钟左右时间，有快有慢

CentOS7 cacti

设置主机的IP地址：

CentOS7 cacti

然后直接选图形，可以查看cacti处理后的图片

CentOS7 cacti

--------------------------添加一台linux服务器：-------------------------
yum install -y \
net-snmp \
net-snmp-utils \
net-snmp-libs \
net-snmp-agent-libs \
net-snmp-devel

配置SNMP 简单网络管理协议
vi /etc/snmp/snmpd.conf

com2sec notConfigUser 192.168.80.100 public #允许哪个服务器监控本机，public团体名

access notConfigGroup "" any noauth exact all none none //把systemview改成all 62

view all included .1 80 // 去掉#号 85

systemctl restart snmpd

可以再cacti服务器端执行如下命令：
snmpwalk -v2c -c public 192.168.80.101
测试能不能抓取到数据
