nagios centos6 install

 

전반적인 IT장비 모니터링 가능,
상세한 Alert 및 Notification 기능제공, map 기능 제공,
장애 이력 관리 및 리포트 제공.. 무료 모니터링 툴 중에선 매우 괜찮은듯 합니다.

 

nagios 설치 작업

centos6.6 , APM 설치

1. nagios core, plugin source 파일 다운로드

wget http://sourceforge.net/projects/nagios/files/nagios-4.x/nagios-4.1.1/nagios-4.1.1.tar.gz

wget http://www.nagios-plugins.org/download/nagios-plugins-2.1.1.tar.gz

 

2. 압축 해제

tar xvf nagios-4.1.1.tar.gz

tar xvf nagios-plugins-2.1.1.tar.gz

 

3. core 설치

cd nagios-4.1.1

./configure --prefix=/usr/local/nagios --with-nagios-user=root --with-nagios-group=root --with-command-user=root --with-command-group=root

make all

make install

make install-init

make install-commandmode

make install-config

make install-webconf

cp /etc/httpd/conf.d/nagios.conf /usr/local/apache/conf/ -> apache install directory

make install-exfoliation

 

 

4. plugin 설치

cd nagios-plugins-2.1.1

./configure --with-nagios-user=root --with-nagios-group=root

make all

make install

 

5. nagios cfg 파일 설정

vim /usr/local/nagios/etc/cgi.cfg

#default_user_name=guest  -> default_user_name=root
authorized_for_system_information=nagiosadmin  ->  authorized_for_system_information=*

authorized_for_configuration_information=nagiosadmin  ->  authorized_for_configuration_information=*

authorized_for_system_commands=nagiosadmin  ->  authorized_for_system_commands=*

authorized_for_all_services=nagiosadmin  ->  authorized_for_all_services=*

authorized_for_all_hosts=nagiosadmin  ->  authorized_for_all_hosts=*

authorized_for_all_service_commands=nagiosadmin  ->  authorized_for_all_service_commands=*

authorized_for_all_host_commands=nagiosadmin  ->  authorized_for_all_host_commands=*

 

 

6. apache 연동

vim /usr/local/apache/conf/nagios.conf

여기서 IfVersion 이런식으로 버전에 따라 설정값이 다른데, 아파치 버전에 맞게 사용하면된다. 아래처럼 사용함.

ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"

 

<Directory "/usr/local/nagios/sbin">

   Options ExecCGI

   AllowOverride None

      Order allow,deny

      Allow from all

      AuthName "Nagios Access"

      AuthType Basic

      AuthUserFile /usr/local/nagios/etc/htpasswd.users

      Require valid-user

</Directory>

 

Alias /nagios "/usr/local/nagios/share"

 

<Directory "/usr/local/nagios/share">

   Options None

   AllowOverride None

      Order allow,deny

      Allow from all

      AuthName "Nagios Access"

      AuthType Basic

      AuthUserFile /usr/local/nagios/etc/htpasswd.users

      Require valid-user

</Directory>

 

 

이제 수정한 nagios.conf 파일을 apache httpd.conf 파일에 추가해야함.

 

vim /usr/local/apache/conf/httpd.conf 내용중 적당한곳에 추가.

 

NameVirtualHost 192.168.0.233:80

<VirtualHost 192.168.0.233:80>

        ServerAdmin pysany@asdf.com

        ServerName 192.168.0.233

        ServerAlias 192.168.0.233

        DocumentRoot /www

        include conf/nagios.conf

        CBandPeriod 1D

        Transferlog '|/usr/local/cronlog/sbin/cronolog /usr/local/apache/logs/transferlog/access_%Y%m%d_transfer_log'

</VirtualHost>

 

 

7. nagios 사용자 및 비밀번호 설정

htpasswd -c /usr/local/nagios/etc/htpasswd.users pandasuper

 

8. 서비스 재시작

/usr/local/apache/bin/httpd -t

/usr/local/apache/bin/httpd -k restart

/etc/init.d/nagios restart

 

9. http://192.168.0.233/nagios 로 접속되는지 확인(본인 웹서버)
