Spark standalone集群（及其外围系统）的构建

物理资源：CentOSA、CentOSB、CentOSC 64bit 内存2G

CentOSA：Zookepper、NameNode、DataNode、journalnode、zkfc、master（spark）、Worker（Spark）、Kafka
CentOSB：Zookepper、NameNode、DataNode、journalnode、zkfc、master（spark）、Worker（Spark）、Kafka
CentOSC:Zookepper、DataNode、journalnode、master（spark）、Worker（Spark）、Kafka
在这里插入图片描述

环境准备

主机名和IP映射

[root@CentOSX ~]# vi /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.111.134 CentOSA
192.168.111.135 CentOSB
192.168.111.136 CentOSC

设置CentOS进程数和文件数(重启)

[root@CentOS ~]# vi /etc/security/limits.conf
* soft nofile 204800
* hard nofile 204800
* soft nproc 204800
* hard nproc 204800
[root@CentOS ~]# reboot

关闭防火墙

[root@CentOSX ~]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]
[root@CentOSX ~]# chkconfig iptables off

同步时钟

[root@CentOSX ~]# yum install -y ntp
[root@CentOSX ~]# ntpdate ntp.ubuntu.com
[root@CentOSX ~]# clock -w

ssh免密认证

[root@CentOSX ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
2c:4b:ba:46:66:27:18:74:11:a7:96:f5:e5:96:97:d5 root@CentOSA
The key's randomart image is:

[root@CentOSX ~]# ssh-copy-id CentOSA
[root@CentOSX ~]# ssh-copy-id CentOSB
[root@CentOSX ~]# ssh-copy-id CentOSC

构建zookeeper集群

安装JDK 这里是jdk-8u191-linux-x64.rpm

[root@CentOSX ~]# rpm -ivh jdk-8u191-linux-x64.rpm
[root@CentOSX ~]# vi .bashrc
JAVA_HOME=/usr/java/latest
PATH=$PATH:$/bin
CLASSPATH=.
export JAVA_HOME
export PATH
export CLASSPATH
[root@CentOSX ~]# source .bashrc
[root@CentOSX ~]# java -version
java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)

安装配置zookeeper集群

[root@CentOSX ~]# tar -zxf zookeeper-3.4.6.tar.gz -C /usr/
[root@CentOSX ~]# mkdir /root/zkdata

[root@CentOSA ~]# echo 1 >> /root/zkdata/myid
[root@CentOSB ~]# echo 2 >> /root/zkdata/myid
[root@CentOSC ~]# echo 3 >> /root/zkdata/myid
[root@CentOSX ~]# vi /usr/zookeeper-3.4.6/conf/zoo.cfg
tickTime=2000
dataDir=/root/zkdata
clientPort=2181
initLimit=5
syncLimit=2

server.1=CentOSA:2887:3887
server.2=CentOSB:2887:3887
server.3=CentOSC:2887:3887

[root@CentOSX ~]# /usr/zookeeper-3.4.6/bin/zkServer.sh start zoo.cfg
[root@CentOSX ~]# /usr/zookeeper-3.4.6/bin/zkServer.sh status zoo.cfg
JMX enabled by default
Using config: /usr/zookeeper-3.4.6/bin/../conf/zoo.cfg
Mode: `follower|leader`

构建Kafka集群

配置与安装

[root@hadoopX ~]# tar -zxf kafka_2.11-2.2.0.tgz -C /usr
[root@hadoop2 ~]# vi /usr/kafka_2.11-2.2.0/config/server.properties
############################# Server Basics #############################
broker.id=[0|1|2]
############################# Socket Server Settings #############################
listeners=PLAINTEXT://CentOS[A|B|C]:9092
############################# Log Basics #############################
# A comma separated list of directories under which to store log files
log.dirs=/usr/kafka-logs
############################# Zookeeper #############################
zookeeper.connect=CentOSA:2181,CentOSB:2181,CentOSC:2181

启动服务

[root@CentOSX ~]# cd /usr/kafka_2.11-2.2.0/
[root@CentOSX kafka_2.11-2.2.0]# ./bin/kafka-server-start.sh -daemon config/server.properties

测试环境

创建topic01

[root@CentOSA kafka_2.11-2.2.0]# ./bin/kafka-topics.sh --zookeeper CentOSA:2181,CentOSB:2181,CentOSC:2181 --create --topic topic01 --partitions 3 --replication-factor 3
Created topic topic01.

这里partitions指定日志分区数目，replication-factor指定分区日志的副本因子。

消费者订阅topic01

[root@CentOSA kafka_2.11-2.2.0]# ./bin/kafka-console-consumer.sh 
                                --bootstrap-server CentOSA:9092,CentOSB:9092,CentOSC:9092 
                                --topic topic01

生产消息

[root@CentOSB kafka_2.11-2.2.0]# ./bin/kafka-console-producer.sh --broker-list CentOSA:9092,CentOSB:9092,CentOSC:9092 --topic topic01
> Hello Kafka

关闭Kafka服务

修改kafka-server-stop.sh

#!/bin/sh
SIGNAL=${SIGNAL:-TERM}
#PIDS=$(ps ax | grep -i 'kafka\.Kafka' | grep java | grep -v grep | awk '{print $1}')
PIDS=$(jps | grep 'Kafka' | awk '{print $1}')
if [ -z "$PIDS" ]; then
  echo "No kafka server to stop"
  exit 1
else
  kill -s $SIGNAL $PIDS
fi

Hadoop NameNode HA

解压并配置HADOOP_HOME

[root@CentOSX ~]# tar -zxvf hadoop-2.9.2.tar.gz -C /usr/
[root@CentOSX ~]# vi .bashrc
