Configuration and integration of the three monitoring platforms (CactiNagiosGanglia)

Official documents for the three types of software: cacti: License

Official documentation for the three types of software:

In the field of monitoring platform, the three monitoring software have their own strengths and weaknesses. This document first introduces the installation and configuration methods of the three software, and then integrates the three software, make use of the advantages of each software.

System Environment: rhel6 selinux and iptables disabled

Cacti:

The cacti software periodically collects host information through the net-snmp protocol and stores it in the mysql database. When you want to view the host information, find the corresponding rra file in the database and use the rrdtool for plotting, then, the image is returned to the user. Its advantage is that it can generate intuitive reports.

Therefore, the premise for cacti to run is to install rrdtool, mysql, php, and a web publishing program. This article uses apache.

First install the required software and dependencies:

# Yum install httpd mysql-server mysql-devel php-mysql php-snmp net-snmp-utils net-snmp-libs net-snmp-devel libart_lgpl-devel libpng-devel freetype-devel cairo-devel pango-devel gcc make

Note that the php-snmp package is in the Optional library.

Start mysql and apache after installation

 

 
 

  
  
# /etc/init.d/httpd start 
  
  
# /etc/init.d/mysqld start 
 
 

Configure PHP: you only need to modify the/etc/php. ini file and set the time zone to Shanghai:

Date. timezone = Asia/shanghai

Configure snmp:

The configuration of snmp in cacti official documents is too cumbersome.

 
 

  
  
# vi /etc/snmp/snmpd.conf 
 
 

Replace some statements in the configuration

 
 

  
  
#com2sec notConfigUser  default       public 
  
  
com2sec local     localhost           public 
  
  
com2sec mynetwork 192.168.0.0/24      public 
  
  
 
  
  
#group   notConfigGroup v1           notConfigUser 
  
  
#group   notConfigGroup v2c           notConfigUser 
  
  
group MyRWGroup v1         local 
  
  
group MyRWGroup v2c        local

group MyROGroup v1         mynetwork 
  
  
group MyROGroup v2c        mynetwork

#syslocation Unknown (edit /etc/snmp/snmpd.conf)

syslocation Linux (RH3_UP2), Home Linux Router.

Start snmpd

 
 

  
  
# chkconfig snmpd on 
  
  
# service snmpd start 
 
 

Install rrdtool

 
 

  
  
# yum install  libxml2-devel 
  
  
# tar zxf rrdtool-1.4.4.tar.gz 
  
  
# cd rrdtool-1.4.4 
  
  
# ./configure  
  
  
# make 
  
  
# make install 
  
  
# ln -s  /opt/rrdtool-1.4.4/bin/rrdtool  /usr/local/bin 
 
 

Install cacti:

 
 

  
  
# tar zxf cacti-0.8.7h.tar.gz 
  
  
# mv cacti-0.8.7h /var/www/html/cacti 
  
  
# cd /var/www/html/cacti/ 
  
  
# useradd cacti 
  
  
# chown -R cacti rra log 
  
  
# mysql cacti < cacti.sql 
 
 

Create a user in the database for cacti, and only have the permission to operate on the cacti database:

 
 

  
  
#mysql 
  
  
mysql> grant all on cacti.* to cacti@localhost identified by 'cacti'; 
  
  
mysql> flush privileges; 
  
  
mysql> quit 
 
 

Edit the cacti configuration file, www.linuxidc.com, and change the user and password used to log on to the database.

 
 

  
  
# vim include/config.php  
  
  
$database_type = "mysql"; 
  
  
$database_default = "cacti"; 
  
  
$database_hostname = "localhost"; 
  
  
$database_username = "cacti"; 
  
  
$database_password = "cacti"; 
  
  
$database_port = "3306"; 
  
  
$database_ssl = false; 
  
  
$url_path = "/cacti/";
