Centos 6 installs Cacti to monitor network traffic

1. Installation of the operating system, there is no need to write tutorials (briefly) I personally use CentOS6.5 minimized installation

Turn off the firewall and selinux after installing the system

# service iptables stop / * disable firewall service * /

# chkconfig iptables off / * permanent shutdown * /

# vim / etc/sysconfig/selinux / * change SELINUX=enforcing to SELINUX=disabled*/

2. Install the software that cacti depends on

# yum-y install mysql mysql-server mysql-devel httpd php php-pdo php-snmp php-mysql lm_sensors net-snmp net-snmp-utils net-snmp-libs rrdtool rrdtool-devel perl-PlRPC perl-DBI perl-rrdtool perl-DBD-MySQL

3. After installing the dependency software, snmp needs to be configured in three places

# vim / etc/snmp/snmpd.conf

Line 41: change "default" in com2sec notConfigUser default public to "127.0.0.1"

Line 62: change "systemview" in "access notConfigGroup"any noauth exact systemview none none" to "all"

Line 85: remove the # sign before the line # view all include. 180

4. After configuring snmp, let's start three important services

# service snmpd start / * start snmp service * /

# chkconfig snmpd on / * set boot * /

# service httpd start

# chkconfig httpd on

# service mysqld start

# chkconfig mysqld on

5. Install and configure cacti

# wget http://www.cacti.net/downloads/cacti-0.8.8b.tar.gz

# tar-zxvf cacti-0.8.8b.tar.gz & & mv cacti-0.8.8b / var/www/html/cacti

6. Set up mysql database

Mysqladmin-u root password

# mysql-uroot-p / * the newly installed mysql does not have a password, so enter directly into the mysql database * /

Mysql > create database cacti; / * first create the cacti database, be careful not to lose the semicolon * /

Mysql > grant all privileges on cacti.* to cacti@localhost identified by 'cacti' with grant option; / * create cacti user and authorize * /

Mysql > use cacti

Mysql > source / var/www/html/cacti/cacti.sql; / * Import cacti database file * /

Mysql > exit

7. Configure cacti

# vim / var/www/html/cacti/include/config.php

$database_type = "mysql"

$database_default = "cacti"

$database_hostname = "localhost"

$database_username = "cactiuser"; / * since the user we previously built in the database is "cacti", the default "cactiuser" here should be changed to "cacti" * /

$database_password = "cactiuser"; / * the default password here should also be changed to "cacti" * /

$database_port = "3306"

8. Add cacti users to write data to rrd and log directories, otherwise pictures will not be generated

# useradd cacti

# cd / var/www/html/cacti

# chown-R cacti rra/ log/

9. Add a task schedule

It is up to cacti to decide how long it takes to generate a monitoring chart. Here, take the default time of 5 minutes for cacti as an example.

# crontab-e

Just join this line and save it.

* / 5 * php / var/www/html/cacti/poller.php > / dev/null 2 > & 1

10. Restart the input http://ip/cacti after configuration
