生产环境实战spark （6）分布式集群 Scala安装
1，scala官网下载scala安装到本地。这里使用spark 2.1.x版本，而spark 2.1 版本需要scala2.1.1版本以上的兼容版本，因此下载安装 scala-2.11.8
下载地址：http://www.scala-lang.org/download/all.html
Spark runs on Java 7+, Python 2.6+/3.4+ and R 3.1+. For the Scala API, Spark 2.1.0 uses Scala 2.11. You will need to use a compatible Scala version (2.11.x).
2，从本地使用winscp工具将scala 2.11.8上传到master节点。
上传后检查

[root@master ~]# cd /usr/local
[root@master local]# ls

3，解压scala进行安装。
[root@master rhzf_spark_setupTools]# unzip scala-2.11.8.zip

[root@master rhzf_spark_setupTools]# ls
jdk-8u121-linux-x64.tar.gz scala-2.11.8 scala-2.11.8.zip
复制到/usr/local目录：
[root@master rhzf_spark_setupTools]# mv scala-2.11.8 /usr/local
[root@master rhzf_spark_setupTools]# cd /usr/local
[root@master local]# ls
bin etc games include jdk1.8.0_121 lib lib64 libexec rhzf_setup_scripts rhzf_spark_setupTools sbin scala-2.11.8 share src
4，配置linux环境变量。vi /etc/profile
export JAVA_HOME=/usr/local/jdk1.8.0_121
export SCALA_HOME=/usr/local/scala-2.11.8
export PATH=.:$PATH:$JAVA_HOME/bin:$SCALA_HOME/bin
在命令行中输入source /etc/profile，使刚才修改的SCALA_HOME及PATH配置文件生效 。
[root@master local]# source /etc/profile[root@master local]# scala -versionScala code runner version 2.11.8 -- Copyright 2002-2016, LAMP/EPFL[root@master local]#
6，编写脚本，在woker的节点也安装scala。
[root@master rhzf_setup_scripts]# ls
rhzf_hosts_scp.sh rhzf_ssh.sh
[root@master rhzf_setup_scripts]# vi rhzf_scala.sh
#!/bin/sh
for i in 238 239 240 241
do
scp -rq /usr/local/scala-2.11.8 root@10.*.*.$i:/usr/local/scala-2.11.8
scp -rq /etc/profile root@10.100.100.$i:/etc/profile
ssh root@10.*.*.$i source /etc/profile
done
[root@master rhzf_setup_scripts]# lsrhzf_hosts_scp.sh rhzf_scala.sh rhzf_ssh.sh[root@master rhzf_setup_scripts]# chmod u+x rhzf_scala.sh[root@master rhzf_setup_scripts]# ./rhzf_scala.sh[root@master rhzf_setup_scripts]#
7， 在woker的节点检查scala安装完成。
