Hadoop安装
1.关闭防火墙
service iptables stop
chkconfig iptables off
2.disable selinux
##disable selinux
sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config
setenforce 0
3.安装jdk
tar xvf jdk1.7.0_71.tar.gz
cp -r jdk1.7.0_71 /opt/
cat >> /etc/profile <<eof
export JAVA_HOME=/opt/jdk1.7.0_71
export PATH=\$JAVA_HOME/bin:\$PATH
EOF
source /etc/profile
rm -rf $INSTALL_HOME/jdk1.7.0_71
安装完成后java -version查看版本
4.添加hadoop用户
useradd hadoop
5.安装ssh
yum install openssh-clients
yum install openssh-server
6.设置ssh无密码登录
ssh-keygen -t rsa
cat id_rsa.pub >> authorized_keys
chmod 600 ./authorized_keys
7.解压hadoop
tar xvf hadoop-2.6.3.tar.gz
mv hadoop-2.6.3 /opt/
chown -R hadoop:hadopp /opt/hadoop-2.6.3
8.配置环境变量
export HADOOP_HOME=/opt/hadoop-2.6.3
export HADOOP_INSTALL=$HADOOP_HOME
export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export YARN_HOME=$HADOOP_HOME
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin
--------配置从节点
9.设置ssh无密码登录
mkdir .ssh
chmod 0700 .ssh
scp authorized_keys hadoop@hadoop-datanode1:/home/hadoop/.ssh/
10.把hadoop软件拷贝到其他节点
scp -r hadoop-2.6.3 root@192.168.16.233:/opt/
chown -R hadoop:hadoop /opt/hadoop-2.6.3
11.其他节点配置环境变量
</eof
cp -r jdk1.7.0_71 /opt/
cat >> /etc/profile <<eof
export JAVA_HOME=/opt/jdk1.7.0_71
export PATH=\$JAVA_HOME/bin:\$PATH
EOF
source /etc/profile
rm -rf $INSTALL_HOME/jdk1.7.0_71
