create virtual machine

eth0: hostonly

eth1: bridge

configure network and host

• set ethX name and write down hardware address

  /etc/udev/rules.d/70-persistent-net.rules

• /etc/sysconfig/network-scripts/ifcfg-eth0

  DEVICE=eth0
  HWADDR=08
   
  :00:27:0F:B6:C1
  TYPE=Ethernet
  UUID=be125edc-4dda-4478-964b-285409fdc735
  ONBOOT=yes
  NM_CONTROLLED=yes
  BOOTPROTO=static
  IPADDR=192.168.56.2

  /etc/sysconfig/network-scripts/ifcfg-eth1

  DEVICE=eth1
  HWADDR=08:00:27:9D:D9:E6
  TYPE=Ethernet
  UUID=be125edc-4dda-4478-964b-285409fdc735
  ONBOOT=yes
  NM_CONTROLLED=yes
  BOOTPROTO=dhcp
   
  

• set host name and gateway

$ vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=master
#GATEWAY=192.168.1.1

• hosts

$vi /etc/hosts 
192.168.56.2 master
192.168.56.3 slave1

install perl

yum install perl

create user

sudo useradd -m cloudera

trun off firewalls

• disable the selinux at all nodes

vi /etc/selinux/config
SELINUX=disabled #carfore! not SELINUXTYPE!!!

• close iptables firewall

chkconfig iptables off
chkconfig ip6tables off
service iptables stop

install JDK(alternative)

remove open jdk

java -version
rpm -qa | grep java

rpm -e --nodeps java-1.5.0-gcj-1.5.0.0-29.1.el6.x86_64
rpm -e --nodeps java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64
rpm -e --nodeps java-1.6.0-openjdk-devel-1.6.0.0-1.66.1.13.0.el6.x86_64

install JDK

CDH5 -> jdk-7u55-linux-x64

jdk7

jdk8

mkdir /usr/java/jdk-version
cd /usr/java/jdk-version
tar zxvf jdk.1.7.0_nn.tar.gz
ln -s /usr/java/jdk.1.7.0_nn /usr/java/default
#or rpm -ivh jdk-7u55-linux-x64.rpm

vi /home/cloudera/.bash_profile

export JAVA_HOME=/usr/java/default
export CLASSPATH=.:$JAVA_HOME/lib:$CLASSPATH  
export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin  

source  /home/hadoop/.bash_profile
rm /usr/java/default.tar.gz
java -version

Ubuntu:

sudo apt-get -o Dpkg::Options::=--force-confdef -o Dpkg::Options::=--force-confold -y install oracle-j2sdk1.7

這步如果跳過的話之後在安裝的時候就勾上要裝JDK

clone virtual machine

clone and configure:

network configure

1. delete /etc/udev/rules.d/70-persistent-net.rules and reboot, or delete primary eth0 & eth1 change eth3 &eth4 to eth0 & eth1
   

   or you can
   remove modprobe: modprobe -r e1000
   reload modprobe: modprobe e1000

2. change name and write down hardware address in

   /etc/udev/rules.d/70-persistent-net.rules

3. change DEVICE, HWADDR, IPADDR in

   /etc/sysconfig/network-scripts/ifcfg-eth0

   restart network: service network restart

4. change host name:

   in /etc/sysconfig/network

   HOSTNAME=

5. write host file

   /etc/hosts

generate ssh key

cd /root/.ssh
ssh-keygen

then send the id_rsa.pub from all nodes(including master) to master

ssh-copy-id master
#or send manually
cat ~/.ssh/id_rsa.pub | ssh hadoop@CDHNode1 'cat >> ~/.ssh/authorized_keys'

finally sent this authorized_keys from master to all of the nodes

scp -r authorized_keys [email protected]
...

理解rsa認證：

mysql

hadoop 本身需要資料庫來維護，選擇mysql來做這個事

yum install -y mysql-server mysql mysql-devel
#/usr/bin/mysqladmin -u root 'old_password' 'new-password'
#SET PASSWORD = Password('password');
chkconfig mysqld on
service mysqld start

vi /etc/my.cnf
