-----------登录到页面-----------
192.168.80.100/cacti/
安装过程
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)。
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
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:
Win7设置:
控制面板—程序和功能
打开服务管理器:
Win+r,services.msc
在添加完设备和图形后,需要重建采集器缓存。
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
设置主机的IP地址:
然后直接选图形,可以查看cacti处理后的图片
--------------------------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
当前题目:CentOS7cacti
