    hadoop2.2.0部署

    下载安装包

    hadoop-2.2.0-cdh5.0.0-beta-1.tar.gz

    解压

    tar zxvf hadoop-2.2.0-cdh5.0.0-beta-1.tar.gz

    ln -s /opt/hadoop-2.2.0-cdh5.0.0-beta-1 ~/hadoop

    所有节点都解压

    ssh双向认证

    配置所有机器hosts

    vi /etc/hosts

    10.10.1.1 hadoop1

    10.10.1.2 hadoop2

    10.10.1.3 hadoop3

    使用hostname 设置主机名

    修改/etc/sysconfig/network 中的内容改为相应的主机名

    在.ssh目录生成id_rsa.pub ，添加到本机~/.ssh/authorized_keys文件里面

    ssh-keygen -q -t rsa

    cat ~/.ssh/id_rsa.pub >>~/.ssh/authorized_keys

    本机登入验证：ssh localhost

    复制authorized_keys到其他机器上

    scp ~/.ssh/id_rsa.pub hadoop3:~/

    cat ~/id_rsa.pub >> ~/.ssh/authorized_keys 

    chmod 600 ~/.ssh/authorized_keys

    chmod 700 ~/.ssh

    其他机器重复以上步骤

    修改环境参数

    vi /etc/profile

    增加以下内容：

    export JAVA_HOME=/opt/jdk1.7.0_51

    export CLASSPATH=.:$JAVA_HOME/lib/tools.jar:/lib/dt.jar

    export PATH=$PATH:$JAVA_HOME/bin

    export HADOOP_DEV_HOME=/home/hadoop/hadoop

    export PATH=$PATH:$HADOOP_DEV_HOME/bin

    修改ulimit

    vi /etc/security/limits.d/90-nproc.conf 

    * soft nproc 502400

    执行环境参数 

    source /etc/profile

    修改hadoop配置

    1.编辑同步脚本:vi hadoop/cp2slaves.sh

    BASE_PATH=`dirname $0`

    cd $BASE_PATH

    echo `/bin/pwd`

    scp etc/hadoop/* hadoop2:~/hadoop/etc/hadoop/

    scp etc/hadoop/* hadoop3:~/hadoop/etc/hadoop/

    2.配置hadoop/etc/hadoop/hadoop-env.sh

    JAVA_HOME修改为：

    export JAVA_HOME=/opt/jdk

    HADOOP_PID_DIR修改为：

    export HADOOP_PID_DIR=${HADOOP_LOG_DIR}

     

    3.创建hadoop工作目录
