单机基于Docker搭建Hadoop2.7.1 Spark1.7 高可用集群
获取Ubuntu镜像
sudo docker pull ubuntu
分别下载 spark1.7 hadoop2.7.1 scala1.1 zookeeper3.4.6 jdk1.8 解压后放置本地文件夹用于挂载到容器中
并在文件夹下创建文件
authorized_keys
hosts
本例目录使用/home/docker/config
启动容器
sudo docker run --name installspark -v /home/docker/config/:/config -it ubuntu:14.04
安装
启动后在容器内/config文件夹下能够看到放置的安装文件
安装jdk,scala :
vim ~/.bashrc
追加:
/usr/sbin/sshd
cat /config/hosts > /etc/hosts
cat /config/authorized_keys > /root/.ssh/authorized_keys
export Java_HOME=/usr/lib/jvm/java-8-sun
export PATH=${JAVA_HOME}/bin:$PATH
export HADOOP_HOME=/opt/hadoop
export PATH=${HADOOP_HOME}/bin:$PATH
export SCALA_HOME=/opt/scala
export PATH=${SCALA_HOME}/bin:$PATH
export SPARK_HOME=/opt/spark
export PATH=${SPARK_HOME}/bin:$PATH
拷贝 spark/hadoop/zookeeper到/opt下
安装hadoop:
创建文件夹:/opt/hadoop/namenode /opt/hadoop/datanode /opt/hadoop/tmp /opt/hadoop/journal
root@nn1:/opt/hadoop/etc/hadoop# vim hadoop-env.sh
修改:
export JAVA_HOME=/usr/lib/jvm/java-8-sun
root@nn1:/opt/hadoop/etc/hadoop# vim core-site.xml
