Selecione a interface de rede referente a internet pelos números ao lado esquerdo

Informe o usuário do no-ip

Senha do usuário

Caso tenha mais de um host cadastrado o sistema perguntará se deseja atualizar todos simultaneamente, digite “n”

Digite “y” para o host que deseja atualizar e “n” para os demais

Deixe o campo vazio “enter”

Informe um “n”

Agora vamos colocar o no-ip para iniciar com o sistema

# cp ./redhat.noip.sh /etc/init.d/noip2

# yum install google-chrome-stable

//Instalando via script
O repositório do Google Chrome não dá mais suporte ao CentOS, logo, mesmo que você adicione o repositório do Google Chrome, não terá êxito na instalação do mesmo via yum.

Sua instalação pode brecar num erro do tipo:
Requires: libstdc++.so.6(GLIBCXX_3.4.15)

Felizmente, Richard Lloyd criou um script que instala automaticamente a versão recente do navegador, instalando as bibliotecas necessárias em /opt/google/chrome/lib.

Para usar este script e instalar o Google Chrome no CentOS 6.x, execute os seguintes comandos no terminal:

# wget http://chrome.richardlloyd.org.uk/install_chrome.sh
# chmod u+x install_chrome.sh
# ./install_chrome.sh

//###############################################
//# CONFIGURANDO O BASICO DO POSTFIX
//###############################################
Este procedimento assume que sua placa de rede assim como o seu servidor DNS (Servidor de Nomes), estão configurados e funcionando corretamente.

# Primeiro verifique se os pacotes do postifx estão instalados na máquina:
rpm -qa | grep postfix

# O resultado deve ser algo parecido com:
# postfix-2.6.6-2.2.el6_1.x86_64
# Caso não apareça, instale os pacotes: postfix-*
# Monte o cd de instalação do SO
mount /mnt/cdrom
# vá até a pasta de pacotes e instale os pacotes
rpm -ivh postfix*

Antes de iniciar o processo de configuração aconselha-se a fazer uma cópia do arquivo original onde serão feitas as alterações, pois se for necessário refazer a configuração desde o início por algum motivo de erro não será preciso reinstalar os pacotes.

# Para fazer a cópia do arquivo original utilize o comando:
cp /etc/postfix/main.cf /tmp

#Configurando o Postfix - editando os arquivos
#Abra o arquivo de confgiuração, digitando:
gedit /etc/postfix/main.cf

Os primeiros passos é para configurar o básico do Postfix para que o mesmo inicie:
Na linha “myhostname”, substituir pelo nome da maquina/host:
myhostname = teste.dominio.com.br

Na linha “mydomain”, substituir pelo seu domínio:
mydomain = dominio.com.br

Esta opção especifica como ficará a terminação do e-mail após o símbolo de @, basta descomentar a opção:

myorigin = $mydomain

Agora cadastre o domínio que seu servidor de email é reponsável:

mydestination = $myhostname, localhost.$mydomain, $mydomain, \
mail.$mydomain, www.$mydomain, dominio.com.br


Caso tenha diversos domínios, pode se informar um arquivo com a listagem de domínios que você possui, coloque os domínios, um seguido do outro separados por vírgula. Não coloque os domínios virtuais nesta parte!
mydestination = $myhostname, localhost.$mydomain, /etc/postfix/dominios

Informe também qual a rede que seu postfix irá trabalhar:
mynetworks = 192.168.0.0/16, 127.0.0.0/8

# CONFIGURAR REDE NO CENTOS 6
###########################################

Primeiro, acesse o diretório de configuração de rede no CentOS:

# cd /etc/syconfig/network-scripts/

Agora vamos editar o arquivo da interface eth0:

# vi ifcfg-eth0

Dentro do arquivo, digite:

DEVICE=eth0
IPADDR=192.168.1.2
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
ONBOOT=yes

Salve o arquivo e reinicie o serviço de rede:

# /etc/rc.d/init.d/network stop
# /etc/rc.d/init.d/network start

Se correu tudo certo, realize um ping em algum site:

$ ping www.google.com.br

Caso não venha ‘pingar’, verifique o arquivo “resolv.conf”:

# vi /etc/resolv.conf

Edite da seguinte forma, caso não saiba nenhum DNS de cabeça, use o seguinte:

# DNS DA UOL
nameserver 200.221.11.100
nameserver 200.221.11.101

Salve, feche o arquivo novamente e realize o teste de ping.

## Instalar o GNOME no CentOS 6
#################################################

# yum update

Para desinstalar:

# yum groupremove “GNOME Desktop Environment” -y
# yum groupremove “X Window System” -y

Veja o arquivo /etc/inittab a linha:

altere assim
id:5:initdefault –> para id:3::initdefault

Quando vc estiver em modo texto (init 3) e necessite iniciar em modo grafico (init 5) basta digitar startx. Mais antes verifique se o serviço xfs esta ativo. com o comando :
# service xfs status

Caso nao esteja digite:
# service xfs start
