Codinome Linux: Instalando o Nagios no FreeBsd

1- Instalando o MySQL

Para instalar o MySQL acesse o diretório:

1	`# cd /usr/ports/databases/mysql51-server/`

Execute o comando de compilação e instalação do MySQL 5.1.52:

1	`# make BUILD_STATIC=yes BUILD_OPTIMIZED=yes WITH_OPENSSL=yes install clean`

Depois de instado o MySQL, vamos habilitar para o que ele inicialize quando o FreeBSD for reiniciado. Editar o arquivo “rc.conf”:

1	`# ee /etc/rc.conf`

Adicionando ao final do arquivo as linhas abaixo, depois salve o arquivo e saia:

1 2	`# MySQL` `mysql_enable="YES"`

Agora vamos iniciar o MySQL com o seguinte comando:

1	`# /usr/local/etc/rc.d/mysql-server start`

1	`# rehash`

Agora vamos realizar as alterações necessárias no MySQL. Primeiro alterar senha de root:

1	`# mysqladmin -uroot password “senha” (sem aspas)`

O próximo passo é criar um arquivo de configuração para o MySQL utilizando os samples existentes

1	`# cp /usr/local/share/mysql/my-large.cnf /var/db/mysql/my.cnf`

Depois acesse o arquivo my.cnf e descomente a linha skip-networking:

1	`# ee /var/db/mysql/my.cnf`

Agora reiniciar o MySQL:

1	`# /usr/local/etc/rc.d/mysql-server restart`

2- Instalando o Apache

Agora vamos executar o comando de compilação e instalação do Centreon:

# cd ../..

# bash ./install.sh -f tmpl/vardistrib/freebsd

Do you want me to configure your sudo ? (WARNING)

[y/n], default to [n]:

> y

Do you want to reload your Apache ?

[y/n], default to [n]:

> n

Feito isso vamos reiniciar o Apache e o MYSQL com o seguinte comando:

1 2	`# /usr/local/etc/rc.d/apache22 restart` `# /usr/local/etc/rc.d/mysql-server restart`

Vamos acertar uma permissão não realizada:

1	`# chown -R www:www /usr/local/etc/centreon/`

Vamos agora testar o Centreon. Use um browser para conectar a:

1	`#` `http://"ip_do_servidor"/centreon`

20- Configurando o Centreon

Siga as etapas a seguir para a configuração do Centreon:

Agora precisamos exportar os arquivos de configuração para que nosso NDO-Utils possa funcionar:

Acesse a guia Configuration

Agora Nagios

Marque todas as opções e clique em Export

Feito isso, podemos inicializar o NDO:

1	`# ee /etc/rc.conf`

Adicionando ao final do arquivo as linhas abaixo, depois salve o arquivo e saia:

1 2	`# NDO2DB` `ndo2db_enable="YES"`

Agora vamos iniciar o MySQL com o seguinte comando:

1	`# /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:

1	`# 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:

1	`# cat /usr/local/etc/cron.d/* >> /etc/crontab`

Reiniciar o CRON

1	`# /etc/rc.d/cron restart`

E agora o Nagios:

1	`# /usr/local/etc/rc.d/nagios restart`
