3 相关文件解释

3.1 有bin目录和sbin目录，sbin目录里放的都是负责管理集群的命令

[shaozhiqi@hadoop102 spark-2.4.3-bin-hadoop2.7]$ cd sbin/
[shaozhiqi@hadoop102 sbin]$ ls
slaves.sh start-mesos-shuffle-service.sh stop-mesos-dispatcher.sh
spark-config.sh start-shuffle-service.sh stop-mesos-shuffle-service.sh
spark-daemon.sh start-slave.sh stop-shuffle-service.sh
spark-daemons.sh start-slaves.sh stop-slave.sh
start-all.sh start-thriftserver.sh stop-slaves.sh
start-history-server.sh  stop-all.sh stop-thriftserver.sh
start-master.sh stop-history-server.sh
start-mesos-dispatcher.sh stop-master.sh
[shaozhiqi@hadoop102 sbin]$

3.2 bin目录里面是一些spark具体的操作命令，如提交任务等

[shaozhiqi@hadoop102 spark-2.4.3-bin-hadoop2.7]$ cd bin/
[shaozhiqi@hadoop102 bin]$ ls
beeline load-spark-env.sh spark-class spark-shell spark-submit
beeline.cmd pyspark spark-class2.cmd spark-shell2.cmd spark-submit2.cmd
docker-image-tool.sh pyspark2.cmd spark-class.cmd spark-shell.cmd spark-submit.cmd
find-spark-home pyspark.cmd sparkR spark-sql
find-spark-home.cmd run-example sparkR2.cmd spark-sql2.cmd
load-spark-env.cmd run-example.cmd sparkR.cmd spark-sql.cmd
[shaozhiqi@hadoop102 bin]$

3.3 Conf主要是spark的配置文件

[shaozhiqi@hadoop102 conf]$ ll
total 36
-rw-r--r--. 1 shaozhiqi shaozhiqi 996 May 1 13:19 docker.properties.template
-rw-r--r--. 1 shaozhiqi shaozhiqi 1105 May 1 13:19 fairscheduler.xml.template
-rw-r--r--. 1 shaozhiqi shaozhiqi 2025 May  1 13:19 log4j.properties.template
-rw-r--r--. 1 shaozhiqi shaozhiqi 7801 May 1 13:19 metrics.properties.template
-rw-r--r--. 1 shaozhiqi shaozhiqi 865 May 1 13:19 slaves.template
-rw-r--r--. 1 shaozhiqi shaozhiqi 1292 May 1 13:19 spark-defaults.conf.template
-rwxr-xr-x. 1 shaozhiqi shaozhiqi 4221 May 1 13:19 spark-env.sh.template
[shaozhiqi@hadoop102 conf]$ pwd
/opt/module/spark-2.4.3-bin-hadoop2.7/conf
[shaozhiqi@hadoop102 conf]$

4. 操作

4.1 重命名这三个配置文件：

[shaozhiqi@hadoop102 conf]$ mv slaves.template slaves
[shaozhiqi@hadoop102 conf]$ mv spark-defaults.conf.template spark-defaults.conf
[shaozhiqi@hadoop102 conf]$ mv spark-env.sh.template spark-env.sh

4.2修改slaves(配置worker)

[shaozhiqi@hadoop102 conf]$ vim slaves
# A Spark Worker will be started on each of the machines listed below.
hadoop102
hadoop103
hadoop104

4.3修改spark-env.sh，配置marster

[shaozhiqi@hadoop102 conf]$ vim spark-env.sh
SPARK_MASTER_HOST=hadoop102
SPARK_MASTER_PORT=7077
# Options for the daemons used in the standalone deploy mode
# - SPARK_MASTER_HOST, to bind the master to a different IP address or hostname
# - SPARK_MASTER_PORT / SPARK_MASTER_WEBUI_PORT, to use non-default ports for the master

4.4分发到我们的其他机器

[shaozhiqi@hadoop102 module]$ testxsync spark-2.4.3-bin-hadoop2.7/

4.5检查是否分发成功

103成功多了spark-2.4.3-bin-hadoop2.7

[shaozhiqi@hadoop103 module]$ ll
total 12
drwxr-xr-x. 15 shaozhiqi shaozhiqi 4096 Jun 30 10:30 hadoop-3.1.2

drwxr-xr-x. 13 shaozhiqi shaozhiqi 4096 Jun 30 18:35 spark-2.4.3-bin-hadoop2.7
[shaozhiqi@hadoop103 module]$

104成功

[shaozhiqi@hadoop104 ~]$ cd /opt/module/
[shaozhiqi@hadoop104 module]$ ll
total 12
drwxr-xr-x. 15 shaozhiqi shaozhiqi 4096 Jun 30 10:27 hadoop-3.1.2
drwxr-xr-x. 7 shaozhiqi shaozhiqi 4096 Jun 23 15:23 jdk1.8.0_211
drwxr-xr-x. 13 shaozhiqi shaozhiqi 4096 Jun 30 18:35 spark-2.4.3-bin-hadoop2.7
[shaozhiqi@hadoop104 module]$

4.6单独启动spark(Hadoop的namenode和datanode都没有启动)

[shaozhiqi@hadoop102 hadoop-3.1.2]$ jps
12022 Jps
[shaozhiqi@hadoop102 hadoop-3.1.2]$

到spark目录

[shaozhiqi@hadoop102 spark-2.4.3-bin-hadoop2.7]$ sbin/start-all.sh

日志中也有fail,验证下页面：

Workers没有其他机器，启动失败

4.7重新修改下我们的配置文件，先停掉spark

[shaozhiqi@hadoop102 spark-2.4.3-bin-hadoop2.7]$ sbin/stop-all.sh
export JAVA_HOME=/opt/module/jdk1.8.0_211
export SPARK_MASTER_HOS=hadoop102
export SPARK_MASTER_PORT=7077

4.8重新分发下修改的配置

[shaozhiqi@hadoop102 module]$ testxsync spark-2.4.3-bin-hadoop2.7/

4.9重新启动spark

[shaozhiqi@hadoop102 spark-2.4.3-bin-hadoop2.7]$ sbin/start-all.sh
starting org.apache.spark.deploy.master.Master, logging to /opt/module/spark-2.4.3-bin-hadoop2.7/logs/spark-shaozhiqi-org.apache.spark.deploy.master.Master-1-hadoop102.out

提交任务
bin/spark-submit
--class org.apache.spark.examples.SparkPi //指定一个主类
--master spark://hadoop102:7077  //指明也提交给那个集群
--executor-memory 1G //任务执行时的内存可不指定
--total-executor-cores 2 // 执行executor个数
./examples/jars/spark-examples_2.11-2.4.3.jar //那个jar包执行
100 //参数

4.13 Spark-shell也可以提交任务。会打开我们的Scala代码编辑器，这样我们可以直接写代码进行提交任务

之所以要替换成IP是因为我们的win10没有配置ip和机器名的映射，此页面的作用我后续会补充
