Centreon 2.1.5 disponivel

luizgustavo — Thu, 04 Mar 2010 13:32:48 +0000

No dia 26/02 a equipe de desenvolvimento do Centreon lançou a nova versão do Centreon 2.1.5, corrigindo uma série de bugs na interface administrativa.

Para ver a lista completa das alterações, veja o anuncio oficial no blog do projeto.

Se você instalou o Centreon utilizando meu tutorial no FreeBSD, veja abaixo como atualiza-lo.

cd /tmp
fetch -o centreon-2.1.5.tar.gz 'http://download.centreon.com/index.php?id=125'
tar zxf centreon-2.1.5.tar.gz
cd centreon-2.1.5
perl -p -i -e 's/\/bin\/bash/\/usr\/local\/bin\/bash/g' install.sh
perl -p -i -e 's/\/bin\/bash/\/usr\/local\/bin\/bash/g' libinstall/*
bash install.sh -u /usr/local/etc/centreon

A partir daí é só responder as perguntas e acessar o Centreon via web para atualizar a base de dados. Sem erro… bem rápido e sem dor

Centreon 2.1.4 on FreeBSD (English)

luizgustavo — Tue, 16 Feb 2010 15:00:30 +0000

This tutorial will guide the User to perform the installation of Centreon on FreeBSD. We will be using an installation in a Jail in FreeBSD kernel version 7.3-PRERELEASE, the kernel version will not influence the tutorial.

What is Centreon?

Centreon is a powerful tool for monitoring hosts and services, it is a frontend that runs on top of Nagios, adding more facilities for viewing and alert history, status, etc. ..

To learn more about the tool, I invite you to visit the official website at the address http://www.centreon.com

What we need?

Apache
PHP + a lot of dependencies
Mysql
Nagios
Pear + a lot of dependencies
Perl + a lot of dependencies
rrdtool
snmp
sudo

Now is the time we start the installation of Centreon for this, we must first download the installation package Centreon and unpack it in a directory to work:

cd /tmp
fetch http://download.centreon.com/centreon/centreon-2.1.4.tar.gz
tar zxf centreon-2.1.4.tar.gz
cd centreon-2.1.4

Let’s make some adjustments to run on FreeBSD:

perl -p -i -e 's/\/bin\/bash/\/usr\/local\/bin\/bash/g' install.sh
perl -p -i -e 's/\/bin\/bash/\/usr\/local\/bin\/bash/g' libinstall/*
mkdir /usr/local/etc/cron.d
cd /tmp/centreon-2.1.4/tmpl/vardistrib
fetch -o freebsd http://www.luizgustavo.pro.br/blog/wp-content/uploads/2010/02/freebsd.txt

We will now begin installing Centreon:

cd ../..
./install.sh -f tmpl/vardistrib/freebsd

Follow as the video:

When installation is complete, we will leave for the web, so, start MySQL and Apache:

/usr/local/etc/rc.d/apache2 start
/usr/local/etc/rc.d/mysql-server start

We hit a permission not ok:

chown -R www:www /usr/local/etc/centreon/

Now so we can point our browser to the server address Centreon:

http:///centreon

Follow the video to configure web:

still need to export the configuration files for our NDO-Utils to work for that accompanies the video on the export of the same web:

That done, we can initialize the NDO:

echo 'ndo2db_enable="YES"' >> /etc/rc.conf
/usr/local/etc/rc.d/ndo2db start

Now, let’s start the process of Centreon:

pw user mod nagios -s /bin/sh
/usr/local/etc/rc.d/centcore start
/usr/local/etc/rc.d/centstorage start

We hit a path within the SUDO:

perl -p -i -e 's/\/etc\/init\.d\/nagios/\/usr\/local\/etc\/rc\.d\/nagios/g' /usr/local/etc/sudoers

Setting the part of CRON for FreeBSD:

cat /usr/local/etc/cron.d/* >> /etc/crontab
/etc/rc.d/cron restart

and now the Nagios:

echo 'nagios_enable="YES"' >> /etc/rc.conf
/usr/local/etc/rc.d/nagios start

Finished ! Now you can set up your hosts and start monitoring.

If you need support Centreon, please contact the Mundounix, we offer support and advice for monitoring networks solution.

Agora é a hora de iniciar-mos a instalação do Centreon, para isso, precisamos primeiramente baixar o pacote de instalação do Centreon e descompacta-lo em um diretorio para trabalhar-mos:

cd /tmp
fetch http://download.centreon.com/centreon/centreon-2.1.4.tar.gz
tar zxf centreon-2.1.4.tar.gz
cd centreon-2.1.4

Vamos fazer alguns acertos para funcionar no FreeBSD:

perl -p -i -e 's/\/bin\/bash/\/usr\/local\/bin\/bash/g' install.sh
perl -p -i -e 's/\/bin\/bash/\/usr\/local\/bin\/bash/g' libinstall/*
mkdir /usr/local/etc/cron.d
cd /tmp/centreon-2.1.4/tmpl/vardistrib
fetch -o freebsd http://www.luizgustavo.pro.br/blog/wp-content/uploads/2010/02/freebsd.txt

Vamos agora iniciar a instalação do Centreon:

cd ../..
./install.sh -f tmpl/vardistrib/freebsd

Acompanhe conforme o vídeo:

Terminada a instalação, vamos partir para a parte web, para isso, inicie o MySQL e o Apache:

/usr/local/etc/rc.d/apache2 start
/usr/local/etc/rc.d/mysql-server start

Vamos acertar uma permissão não realizada:

chown -R www:www /usr/local/etc/centreon/

Agora assim, podemos apontar nosso navergador para o endereço do servidor centreon:

http:///centreon

Acompanhe o vídeo para configurar via web:

Falta pouco… ainda precisamos exportar os arquivos de configuração para que nosso NDO-Utils possa funcionar, para isso, acompanhe o vídeo na exportação do mesmo via web:

Feito isso, podemos inicializar o NDO:

echo 'ndo2db_enable="YES"' >> /etc/rc.conf
/usr/local/etc/rc.d/ndo2db start

Agora, vamos iniciar os processos do Centreon:

pw user mod nagios -s /bin/sh
/usr/local/etc/rc.d/centcore start
/usr/local/etc/rc.d/centstorage start

Vamos acertar um path dentro do SUDO:

perl -p -i -e 's/\/etc\/init\.d\/nagios/\/usr\/local\/etc\/rc\.d\/nagios/g' /usr/local/etc/sudoers

Acertar a parte da CRON para o FreeBSD:

cat /usr/local/etc/cron.d/* >> /etc/crontab
/etc/rc.d/cron restart

E agora o Nagios:

echo 'nagios_enable="YES"' >> /etc/rc.conf
/usr/local/etc/rc.d/nagios start

Pronto ! agora é só configurar os seus hosts e iniciar o monitoramento.

Se necessitar de suporte ao Centreon, entre em contato com a Mundounix, nós oferecemos suporte e consultoria para solução de monitoramento de redes.
