在hadoop2.4集群环境下安装spark

1、下载spark最新版：http://spark.apache.org/downloads.html

     下载对应的Scala版本：http://www.scala-lang.org/download/

2、解压文件：

root@Mhadoop:/home/hadoop/Downloads# tar -zxf spark⑴.3.1-bin-hadoop2.4.tgz 

3、创建spark目录：

root@Mhadoop:/home/hadoop/Downloads# mkdir /usr/local/spark
root@Mhadoop:/home/hadoop/Downloads# mv spark⑴.3.1-bin-hadoop2.4 /usr/local/spark/
root@Mhadoop:/home/hadoop/Downloads# cd /usr/local/spark/
root@Mhadoop:/usr/local/spark# ls
spark⑴.3.1-bin-hadoop2.4

4、一样安装Scala;

root@Mhadoop:/home/hadoop/Downloads# tar -zxf ./scala⑵.11.6.tgz 
root@Mhadoop:/home/hadoop/Downloads# ls
scala⑵.11.6  scala⑵.11.6.tgz  spark⑴.3.1-bin-hadoop2.4.tgz
root@Mhadoop:/home/hadoop/Downloads# mkdir /usr/lib/scala
root@Mhadoop:/home/hadoop/Downloads# mv ./scala⑵.11.6 /usr/lib/scala/

5、配置环境变量：

geidt ~/.bashrc

加入以下内容：

export PATH=$PATH:$HADOOP_HOME/bin:$SCALA_HOME/bin:$SPARK_HOME/bin

export SCALA_HOME=/usr/lib/scala/scala⑵.11.6
export SPARK_HOME=/usr/local/spark/spark⑴.3.1-bin-hadoop2.4

使配置生效：source ~/.bashrc

6、配置spark：

进入conf目录，修改spark-env.sh

export JAVA_HOME=/usr/lib/jvm/java⑺-oracle
export HADOOP_CONF_DIR=/usr/local/hadoop/etc/hadoop
export SPARK_MASTER_IP=Mhadoop
export SPARK_WORKER_MEMORY=1g
export SCALA_HOME=/usr/lib/scala/scala⑵.11.6
export SPARK_HOME=/usr/local/spark/spark⑴.3.1-bin-hadoop2.4

修改slaves文件;

Mhadoop
Shadoop1
Shadoop2

7、配置slave节点：

copy文件到slave节点：

sudo scp scala⑵.11.6.tgz  spark⑴.3.1-bin-hadoop2.4.tgz  hadoop@Shadoop1:/home/hadoop/Downloads/

sudo scp scala⑵.11.6.tgz  spark⑴.3.1-bin-hadoop2.4.tgz  hadoop@Shadoop2:/home/hadoop/Downloads/

在两个slave节点做一样配置

hadoop@Shadoop1:~$ sudo mkdir /usr/lib/scala
[sudo] password for hadoop: 
hadoop@Shadoop1:~$ sudo mkdir /usr/local/spark
hadoop@Shadoop1:~$ cd /home/hadoop/Downloads/
hadoop@Shadoop1:~/Downloads$ ls
scala⑵.11.6.tgz  spark⑴.3.1-bin-hadoop2.4.tgz
hadoop@Shadoop1:~/Downloads$ tar -zxf scala⑵.11.6.tgz 
hadoop@Shadoop1:~/Downloads$ tar -zxf spark⑴.3.1-bin-hadoop2.4.tgz 
hadoop@Shadoop1:~/Downloads$ sudo mv scala⑵.11.6 /usr/lib/scala/
hadoop@Shadoop1:~/Downloads$ sudo mv spark⑴.3.1-bin-hadoop2.4 /usr/local/spark/

复制环境信息到slave节点：

hadoop@Mhadoop:~/Downloads$ sudo scp /home/hadoop/.bashrc hadoop@Shadoop1:/home/hadoop
hadoop@shadoop1's password: 
.bashrc                                       100% 3972     3.9KB/s   00:00    
hadoop@Mhadoop:~/Downloads$ sudo scp /home/hadoop/.bashrc hadoop@Shadoop2:/home/hadoop

8、启动hadoop和spark：

首先启动hadoop：用jps查看

hadoop@Mhadoop:/usr/local/hadoop/sbin$ jps
4316 ResourceManager
4167 SecondaryNameNode
4596 Jps
3861 NameNode

再进入spark的sbin目录，输入命令：./start-all.sh

注意必须标明是当前目录下的，否则履行的多是hadoop的sbin目录下的；

再用jps查看：

hadoop@Mhadoop:/usr/local/spark/spark⑴.3.1-bin-hadoop2.4/sbin$ jps
6280 Master
4316 ResourceManager
4167 SecondaryNameNode
6571 Worker
3861 NameNode
6625 Jps

多了Master和Worker进程。（slave节点都多了worker进程）

9、大功告成，进入8080端口
