This experiment needs to be connected to the Internet, so two network cards are needed, one is host only and the other is bridged.

Installation process

The user name and password default to admin, and the password needs to be changed after login (at least eight digits and complex)

Reset the password, which is a combination of uppercase and lowercase special characters

Revisit: http://192.168.80.10/cacti/

(console) Console-> system configuration-> Settings (Cacti Settings)-> Paths-> enter the configuration file path / usr/local/spine/bin/spine in the Spine Binary File Location text box, and click Save (Save).

Console-> Settings (Cacti Settings)-> Poller-> Select spine in the Poller Type drop-down box, and click Save (Save). Note: if you use spine, the following two rotation training times and scheduled task intervals should be set to every Minute

If you report an error when viewing graphic data: / bin/rrdtool: symbol lookup error: / lib64/libpango-1.0.so.0:undefined symboll solution: yum update glib2-y if you report an error: error:opening'/ var/www/html/cacti/rra/local_linux_machine_load_1min_2.rrd':No such file or directory solution: chmod-R 777 / var/www/html/cacti/rra/usr/bin/php / var/www/html/cacti/poller.php

Add a device:

Win7 settings:

Control Panel-programs and Features

Open the Service Manager:

Win+r,services.msc

After adding devices and graphics, you need to rebuild the collector cache.

Check it on cacti.

Manage à equipment (device)

Just check that the linux status is UP. Be careful not to worry. It takes about 2-5 minutes for spine mode to just start, some fast and some slow.

Set the IP address of the host:

Then select the drawing directly, and you can view the picture processed by cacti

-add a linux server:-

Yum install-y\

Net-snmp\

Net-snmp-utils\

Net-snmp-libs\

Net-snmp-agent-libs\

Net-snmp-devel

Configure SNMP simple Network Management Protocol

Vi / etc/snmp/snmpd.conf

Com2sec notConfigUser 192.168.80.100 public # which server is allowed to monitor the native machine, public community name

Access notConfigGroup "" any noauth exact all none none / / change systemview to all 62

View all included. 180 / / remove # 85

Systemctl restart snmpd

You can execute the following command on the cacti server:

Snmpwalk-V2C-c public 192.168.80.101
