大数据-spark HA集群搭建

Posted 2021-02-10 Angel_jing

一、安装scala

我们安装的是scala-2.11.8  5台机器全部安装

下载需要的安装包，放到特定的目录下/opt/workspace/并进行解压

1、解压缩

[root@master1 ~]# cd /opt/workspace
[root@master1 workspace]#tar -zxvf scala-2.11.8.tar.gz 

2、配置环境变量  /etc/profile文件中添加spark配置

[root@master1 ~]# vi /etc/profile

# Scala Config

export SCALA_HOME=/opt/software/scala-2.11.8
export PATH=$SCALA_HOME/bin:$PATH

[root@master1 ~]# source /etc/profile

3、启动scala

[root@master1 workspace]# vim /etc/profile
[root@master1 workspace]# scala -version
-bash: /opt/workspace/scala-2.11.8/bin/scala: 权限不够
[root@master1 workspace]# chmod +x /opt/workspace/scala-2.11.8/bin/scala
[root@master1 workspace]# scala -version
Scala code runner version 2.11.8 -- Copyright 2002-2016, LAMP/EPFL
[root@master1 workspace]# scala
Welcome to Scala 2.11.8 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_181).
Type in expressions for evaluation. Or try :help.

二、安装spark

1、下载spark对应版本

因为后期需要安装Hive，并且会运行hive on spark模式，为避免jar冲突，我们去掉了spark中的hive部分。

我们应用的是spark-2.3.0-bin-hadoop2-without-hive.tgz 自己编译的版本

可参考https://blog.csdn.net/sinat_25943197/article/details/81906060进行编译

2、文件解压

[root@master1 workspace]# tar -zxvf spark-2.3.0-bin-hadoop2-without-hive.tgz 

 3、配置文件 spark-env.sh  slaves、/etc/profile

/etc/profile文件中添加

# Spark Config
export SPARK_HOME=/opt/workspace/spark-2.3.0-bin-hadoop2-without-hive
export PATH=.:${JAVA_HOME}/bin:${SCALA_HOME}/bin:${MAVEN_HOME}/bin:$HADOOP_HOME/sbin:$HADOOP_HOME/bin:${SPARK_HOME}/bin:$SQOOP_HOME/bin:${ZK_HOME}/bin:$PATH

source /etc/profile

spark-env.sh.template重新命名为spark-env.sh文件、配置如下：

slaves.template文件重新命名为slaves、配置如下：

# A Spark Worker will be started on each of the machines listed below.
slave1
slave2
slave3

4、启动spark

[root@master1 workspace]# ./spark-2.3.0-bin-hadoop2-without-hive/sbin/start-all.sh

报错：默认是22端口，进行ssh端口修改

解决：在spark-env.sh中增加端口

export SPARK_SSH_OPTS="-p 61333"

重新启动spark

启动成功

5、手动启动备用master

[root@master2 workspace]# ./spark-2.3.0-bin-hadoop2-without-hive/sbin/start-master.sh
