Nagios Learning Practice Series-Basic installation articles

Introduction to the outset

Recently due to work needs, learning to study the installation, configuration, use of Nagios, about Nagios introduction, you can refer to my previous essay Nagios Learning Practice Series-Product introduction

Experimental environment

Operating system: Red Hat Enterprise Linux Server Release 6.0 (Santiago).

Note that Nagios can only be installed on Linux or UNIX platforms, does not support the Windows platform, and of course it can monitor the Windows platform.

Environment preparation

Apache and PHP are not required to install Nagios, in fact, it is necessary, you can not analyze the Nagios log bar, because Nagios provides a web monitoring interface, through the Web monitoring interface can clearly see the monitoring of the host, services, resources running state, therefore, It is necessary to install a Web service environment. Details on the installation configuration of Apache and PHP can be found in my essay: Linux system Installation Appach 2.4.6 and Redhat Server 5.7 installation configuration PHP, there will not be too much detail to introduce.

One: Installation APACHE

First check whether to install GCC, gcc-c++ package, because we are under the source code compiled to install Apache software.

[Email protected] nagios]# tar zxvf apr-1.4.8.tar.gz

[Email protected] nagios]# CD apr-1.4.8

[Email protected] apr-1.4.8]# MKDIR/USR/LOCAL/APR

[Email protected] apr-1.4.8]#/configure--PREFIX=/USR/LOCAL/APR

[[email protected] apr-1.4.8]# make & make Install

Verify that the APR package is installed successfully, and if you can see four directories such as bin, build-1, etc. in the installation directory, you have successfully installed the APR package.

[Email protected] nagios]# CD pcre-8.33

[Email protected] pcre-8.33]# Mkdir/usr/local/pcre

[Email protected] pcre-8.33]#/configure--prefix=/usr/local/pcre--with-apr=/usr/local/apr/bin/apr-1-config

[[email protected] pcre-8.33]# make && make install

3:apache HTTP Server Installation

[Email protected] nagios]# tar xzvf httpd-2.4.6.tar.gz

[Email protected] nagios]# CD httpd-2.4.6

[Email protected] httpd-2.4.6]# Mkdir/usr/local/apache

[Email protected] httpd-2.4.6]#/configure--prefix=/usr/local/apache/--with-pcre=/usr/local/pcre/--with-apr=/ USR/LOCAL/APR--with-apr-util=/usr/local/apr-util

[[email protected] httpd-2.4.6] #make && make install

Configure httpd.conf, locate the servername option, and add the server IP address below, as shown below

[Email protected] conf]# cd/usr/local/apache/conf

[[email protected] conf]# ls

Extra httpd.conf Magic Mime.types Original

[Email protected] conf]# VI httpd.conf

Launch Apache service, verify the installation is successful, if you enter http://localhost/in the browser display "It works!", that means that Apache has been installed successfully

[[email protected] conf]#/usr/local/apache/bin/apachectl start

HTTPD (PID 11025) already running

Two: Install PHP

[Email protected] nagios]# tar zxvf php-5.3.26.tar.gz

[Email protected] nagios]# CD php-5.3.26

[Email protected] nagios]#/configure--prefix=/usr/local/php--with-apxs2=/usr/local/apache/bin/apxs

The error occurred during configuration, because of the missing Libxml2-devel package, the Libxml2-devel package needs to be installed first

[email protected] php-5.3.26]# Yum install Libxml2-devel

[Email protected] nagios]#/configure--prefix=/usr/local/php--with-apxs2=/usr/local/apache/bin/apxs

[[email protected] nagios]# make

[[email protected] nagios]# make test

[[email protected] nagios]# make install

[Email protected] conf]# cd/usr/local/apache/conf

Under the/usr/local/apache/conf directory, configure the httpd.conf file to add index.php

<ifmodule dir_module>

DirectoryIndex index.html

</IfModule>

Next find <ifmodule mime_module> Add configuration information AddType application/x-httpd-php. PHP, other configurations, etc. install the Nagios-related package for configuration.

Nagios Installation

STEP1: Check if the package is installed because Nagios needs to rely on these packages to provide services

[Email protected] nagios]# rpm-q gcc glibc glibc-common gd gd-devel xinetd openssl-devel

Because I have no gd-devel under the mirror, if you do not install the package, you will encounter some problems later, this package must be installed.
