Instalação e Configuração do OCS no Debian Squeeze
OCS Inventory é um software livre que permite aos usuários conhecerem seus ativos de TI. OCS-NG coleta informações sobre o hardware e software de máquinas em rede rodando o programa cliente OCS (“OCS Inventory Agent”). OCS pode ser usado para visualizar o inventário através de uma interface web. Além disso, OCS compreende a possibilidade de implantação de aplicativos nos computadores de acordo com os critérios de pesquisa. Agente de lado-IpDiscover torna possível saber a totalidade de computadores em rede e dispositivos
Prepare o seu sistema com o seguinte script http://wiki.douglasqsantos.com.br/doku.php/confinicialsqueeze_en para que não falte nenhum pacote ou configuração.
O que vou utilizar:
- Nome Servidor: ocs
- Ip LAN: 192.168.1.31
Vamos fazer um update dos repositórios e um upgrade do sistema
aptitude update && aptitude dist-upgrade -y
Agora vamos mandar instalar o bando de dados MySQL
aptitude install mysql-server -y
Aqui vamos ser questionados sobre a senha do usuário root, informe ela e confirme.
Agora precisamos fazer um ajuste no arquivo de configuração do MySQL
vim /etc/mysql/my.cnf [...] max_allowed_packet = 32M
Agora vamos reiniciar o MySQL
/etc/init.d/mysql restart
Agora vamos instalar o apache e o php
aptitude install apache2 php5 php5-mysql php5-gd -y
Agora vamos instalar o módulo perl para o apache
aptitude install libapache2-mod-perl2 -y
Agora vamos instalar alguns módulos perl que são necessários para o OCS funcionar
apt-get install libxml-simple-perl libcompress-zlib-perl libdbi-perl libdbd-mysql-perl libapache-dbi-perl libnet-ip-perl libsoap-lite-perl -y
Agora vamos instalar o CPAN e mais alguns módulos necessários
perl -MCPAN -e shell cpan[1]> install CPAN cpan[2]> reload CPAN cpan[3]> force install YAML cpan[4]> force install XML::Entities cpan[5]> force install Nmap::Parser cpan[6]> force install Proc::PID::File cpan[7]> quit Terminal does not support GetHistory. Lockfile removed
Agora vamos mandar instalar o snmp e o nmap
aptitude install nmap snmp -y
Agora precisamos obter o ocs vamos acessar o diretório /usr/src e vamos obter ele
cd /usr/src wget -c http://wiki.douglasqsantos.com.br/Downloads/monitoring/OCSNG_UNIX_SERVER-2.0.5.tar.gz
Agora vamos desempacotar ele
tar -xzvf OCSNG_UNIX_SERVER-2.0.5.tar.gz
Agora vamos acessar o diretório do ocs
cd OCSNG_UNIX_SERVER-2.0.5/
Agora vamos mandar instalar ele

Agora vamos criar a base de dados para o nosso ocs
mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.

Type '\c' to clear the current input statement. mysql> create database ocsweb; Query OK, 1 row affected (0.01 sec) mysql> grant all privileges on ocsweb.* to ocsweb@localhost identified by 'senha'; Query OK, 0 rows affected (0.02 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> quit Bye
Agora precisamos fazer um ajuste no arquivo de controle da configuração dos clientes que vão se conectar no ocs
sed -i 's/PerlSetEnv OCS_DB_USER ocs/PerlSetEnv OCS_DB_USER ocsweb/g' /etc/apache2/conf.d/z-ocsinventory-server.conf sed -i 's/PerlSetVar OCS_DB_PWD ocs/PerlSetVar OCS_DB_PWD senha/g' /etc/apache2/conf.d/z-ocsinventory-server.conf sed -i 's/PerlSetEnv OCS_OPT_SUPPORT 1/PerlSetEnv OCS_OPT_SUPPORT 0/g' /etc/apache2/conf.d/z-ocsinventory-server.conf
Agora vamos ajustar algumas variáveis do php, para caso aja a necessidade de enviar algum programa ou msi para o ocs nós vamos ter uma limitação de tamanho que eu estou ajustando para 300MB
vim /etc/php5/apache2/php.ini [...] max_execution_time = 180 [...] max_input_time = 180 [...] memory_limit = 256M [...] upload_max_filesize = 300M [...] post_max_size = 300M
Agora vamos ajustar agora as variáveis do php do ocsinventory
vim /etc/apache2/conf.d/ocsinventory-reports.conf
[...]
php_value post_max_size 300m
php_value upload_max_filesize 300m
Agora vamos mandar reiniciar o apache
/etc/init.d/apache2 restart
Agora vamos acessar http://192.168.1.31/ocsreports
Aqui vamos informar:
- No primeiro campo precisamos informar: ocsweb
- No segundo campo precisamos informar: senha
- No terceiro campo precisamos informar: ocsweb
- No ultimo campo precisamos informar: localhost
- Agora precisamos clicar no botão de envio.
- Na próxima página é só clicar em Enviar
- Agora é só clicarmos em Click here to enter OCS-NG GUI
Agora fomos direcionado para a tela de login usuário: admin senha: admin, para mudarmos o idioma é só selecionar a bandeira do país desejado
Aqui vamos ter o seguinte aviso
SECURITY ALERT! Your install.php exists in your installation directory. The default login/password is activate on OCS-NG GUI
Agora precisamos remover o script de instalação
rm -rf /usr/share/ocsinventory-reports/ocsreports/install.php
Agora no ocs selecione o icone com uma carinha:
- Agora selecione adicionar um novo usuário
- Aqui informe o user ID ex: douglas
- Em tipo selecione: Super administradores
- Agora em nome informe o nome ex: Douglas
- Agora em LASTNAME informe o sobrenome ex: Santos
- Em email informe o email ex: douglas@douglasqsantos.com.br
- Em comentário se quiser colocar algo fique avontade
- Agora informe uma senha
- Agora selecione o icone verde.
Agora na parte superior da tela selecione o icone vermelho para fazer o logout
Agora logue novamente com o usuário criado.
Agora selecione novamente o icone com uma carinha
- Agora selecione Super administradores
- Agora no usuário admin selecione Apaga e confirme a exclusão
- Agora faça logout novamente para a mensagem de aviso desaparecer
Agora vamos instalar o agente no servidor pois ele vai ser cliente tambem
aptitude install ocsinventory-agent -y
Aqui informe
- http
Agora vamos registrar o nosso servidor no ocs
ocsinventory-agent [info] Accountinfo file doesn't exist. I create an empty one. [info] PROLOG_FREQ has changed since last process(old=,new=24)
Agora é só acessar o ocsweb e verificar o servidor cadastrado
Agora vamos ver a configuração de um cliente CentOS
yum install ocsinventory-agent -y
Agora vamos configurar o ocsinventory-agent deixe o arquivo como abaixo
vim /etc/ocsinventory/ocsinventory-agent.cfg [...] # Server URL, unconmment if needed server = 192.168.1.31/ocsinventory #local = /var/lib/ocsinventory-agent
Agora vamos registrar o nosso servidor no ocs
ocsinventory-agent [info] Accountinfo file doesn't exist. I create an empty one. [info] PROLOG_FREQ has changed since last process(old=,new=24)
Agora é só acessar o ocsweb e verificar o servidor cadastrado
Para instalação dos agente em novos clientes linux é só seguir o mesmo procedimento.
A instalação em máquinas Windows podemos fazer da seguinte forma:
- Precisamos obter o arquivo: http://wiki.douglasqsantos.com.br/Downloads/monitoring/OCSNG-Windows-Agent-2.0.zip
- Descompacte o arquivo;
- Execute o programa OCS-NG-Windows-Agent-Setup.exe
- Selecione Next
- Selecione I Agree
- Selecione Next
- Informe o Endereço do servidor http://192.168.1.31/ocsinventory e clique em Next
- Clique em Next
- Marque o checkbox Immediatly launch inventory… e Selecione em Next
- Selecione Install
- Agora selecione Finish
Agora é só conferir a nova máquina no ocs
