C/S mode, collect monitoring data

b/S mode, management monitoring platform

1. Environment deployment

environment: host a and host b The operating system is centos6.6 x86_64 , minimized installation, all closed selinux a as the monitoring side, the host b as being imported Euguantang, ip addresses are 192.168.131.138 192 168.131.139

1. Deploying the Cacti Runtime environment

# yum-y Install httpd mysql mysql-server mysql-devel php php-mysql

# yum-y Install RRDtool

# yum-y Install Net-snmp net-snmp-utils

# service httpd Start

# Chkconfig httpd on

# service Mysqld Start

# Chkconfig Mysqld on

# service SNMPD Start

# chkconfig SNMPD on

1. Installing cacti

# Tar XF cacti-0.8.7g.tar.gz-c/var/www/html/

# cd/var/www/html/

# MV Cacti-0.8.7g/cacti

# Vim cacti/include/config.php

in the browser input http://192.168.131.138/cacti/install/ , enter Cacti Installation Wizard

1. Configuring the monitored side

# yum-y Install Net-snmp

# vim/etc/snmp/snmpd.conf

Com2sec Notconfiguser 192.168.131.138 public123

Access Notconfiggroup "" Any noauth exact none none

# service SNMPD Start

1. Configure Server-side

# vim/etc/snmp/snmpd.conf

# Service SNMPD Restart

1. Configuring monitoring

in the Cacti Web Interface

Click on the " Devices " à "Add"

Add an image tree

Monitoring side operation

# SU–CACTI

$ php/var/www/html/cacti/poller.php # Start Synchronizing Data

# crontab–e
