apache大数据数仓各组件部署搭建
第一章 环境准备
1. 机器规划
准备3台服务器用于集群部署，系统建议CentOS7+，2核8G内存
172.19.195.228 hadoop101
172.19.195.229 hadoop102
172.19.195.230 hadoop103
[root@hadoop101 ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)
[root@hadoop101 ~]# hostname
hadoop101
2. 安装包下载准备
数仓部署组件安装包：
链接：https://pan.baidu.com/s/1Wjx6TNkedMTmmnuWREW-OQ
提取码：bpk0
已经把相关组件均上传至网盘，也可自行去各自官方地址去下载收集；
3. 配置服务器hosts
3台机器的/etc/hosts主机名解析配置：
# hadoop101
[root@hadoop101 ~]# cat /etc/hosts
127.0.0.1 localhost localhost
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
# hadoop集群
172.19.195.228 hadoop101
172.19.195.229 hadoop102
172.19.195.230 hadoop103# hadoop102
[root@hadoop102 ~]# cat /etc/hosts
127.0.0.1 localhost localhost
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
# hadoop集群
172.19.195.228 hadoop101
172.19.195.229 hadoop102
172.19.195.230 hadoop103# hadoop103
[root@hadoop103 ~]# cat /etc/hosts
127.0.0.1 localhost localhost
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
# hadoop集群
172.19.195.228 hadoop101
172.19.195.229 hadoop102
172.19.195.230 hadoop103
4. 配置服务器之间免密登录
# 创建密钥
[root@hadoop101 ~]# 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:
SHA256:pgAtkJ9Tmf8sqBYOkK2gr/d7woIPXDguOiHRxRHDVH4 root@hadoop101
The key's randomart image is:
+---[RSA 2048]----+
|.. +=*. |
|.. .Bo |
| =o+... E |
|= Bo .. |
|+= o.. oS |
|O + ...oo |
|+O + .. |
|=.B o . |
|o*.oo+ |
+----[SHA256]-----+# 分发密钥
[root@hadoop101 ~]# ssh-copy-id hadoop101
Are you sure you want to continue connecting (yes/no)? yes
root@hadoop101's password:
Number of key(s) added: 1
Now try logging into the machine, with: "ssh 'hadoop101'"
and check to make sure that only the key(s) you wanted were added.[root@hadoop101 ~]# ssh-copy-id hadoop102
Are you sure you want to continue connecting (yes/no)? yes
root@hadoop102's password:
Number of key(s) added: 1
Now try logging into the machine, with: "ssh 'hadoop102'"
and check to make sure that only the key(s) you wanted were added.[root@hadoop101 ~]# ssh-copy-id hadoop103
Are you sure you want to continue connecting (yes/no)? yes
root@hadoop103's password:
Number of key(s) added: 1
Now try logging into the machine, with: "ssh 'hadoop103'"
and check to make sure that only the key(s) you wanted were added.# hadoop102和hadoop103操作相同
[root@hadoop102 ~]# ssh-keygen -t rsa
[root@hadoop102 ~]# ssh-copy-id hadoop101
[root@hadoop102 ~]# ssh-copy-id hadoop102
[root@hadoop102 ~]# ssh-copy-id hadoop103[root@hadoop103 ~]# ssh-keygen -t rsa
[root@hadoop103 ~]# ssh-copy-id hadoop101
[root@hadoop103 ~]# ssh-copy-id hadoop102
[root@hadoop103 ~]# ssh-copy-id hadoop103# 验证
[root@hadoop101 ~]# for i in hadoop101 hadoop102 hadoop103;do ssh $i hostname;done
hadoop101
hadoop102
hadoop103
5. 创建安装包和应用目录
[root@hadoop101 ~]# for i in hadoop101 hadoop102 hadoop103;do ssh $i mkdir /opt/{software,module};done
6. 上传安装包至服务器
# 上传所有安装包至hadoop101 /opt/software目录
[root@hadoop101 ~]# cd /opt/software/
[root@hadoop101 software]# ll
total 1489048
-rw-r--r-- 1 root root 278813748 Aug 26 15:13 apache-hive-3.1.2-bin.tar.gz

-rw-r--r-- 1 root root 232530699 Aug 26 15:15 spark-2.4.5-bin-hadoop2.7.tgz
7. 各服务器关闭防火墙
# 防火墙关闭
[root@hadoop101 software]# systemctl stop firewalld.service
[root@hadoop101 software]# systemctl disable firewalld.service[root@hadoop102 ~]# systemctl stop firewalld.service
[root@hadoop102 ~]# systemctl disable firewalld.service[root@hadoop103 ~]# systemctl stop firewalld.service
[root@hadoop103 ~]# systemctl disable firewalld.service
8. 本地Windows电脑配置hosts( 可选 )
【注意】如果不配置则涉及URL访问时，浏览器访问时需要使用各服务器ip地址
C:\Windows\System32\drivers\etc\hosts
# hadoop集群
139.224.229.107 hadoop101
139.224.66.13 hadoop102
139.224.228.144 hadoop103
9. 安装java ( jdk1.8 )
# 解压包
[root@hadoop101 software]# tar -xf jdk-8u211-linux-x64.tar.gz -C /opt/module/
[root@hadoop101 software]# ls /opt/module/
jdk1.8.0_211# 增加环境变量配置
[root@hadoop101 software]# vim /etc/profile
#JAVA_HOME
export JAVA_HOME=/opt/module/jdk1.8.0_211
export PATH=$PATH:$JAVA_HOME/bin# 分发jdk目录至hadoop102、hadoop103

第二章 zookeeper安装部署
zookeeper完整详细的内容介绍可见zookeeper简介、zookeeper部署以及原理介绍
1. 解压zookeeper安装包
[root@hadoop101 software]# tar -xf apache-zookeeper-3.5.7-bin.tar.gz -C /opt/module/
2. 创建zkData目录
[root@hadoop101 software]# mkdir -p /opt/module/apache-zookeeper-3.5.7-bin/zkData
3. 设定节点myid号
[root@hadoop101 software]# echo 1 > /opt/module/apache-zookeeper-3.5.7-bin/zkData/myid
4. 修改zoo.cfg配置文件
[root@hadoop101 software]# cd /opt/module/apache-zookeeper-3.5.7-bin/conf/
[root@hadoop101 conf]# ll

[root@hadoop101 conf]# mv zoo_sample.cfg zoo.cfg
[root@hadoop101 conf]# vim zoo.cfg
# 为方便查看,将注释行都删去,可保留
[root@hadoop101 conf]# cat zoo.cfg
tickTime=2000

server.2=hadoop102:2888:3888
server.3=hadoop103:2888:3888
[root@hadoop101 conf]#
5. 分发应用目录
[root@hadoop101 module]# scp -r apache-zookeeper-3.5.7-bin hadoop102:/opt/module/
[root@hadoop101 module]# scp -r apache-zookeeper-3.5.7-bin hadoop103:/opt/module/
6. 更改其它节点myid号
[root@hadoop102 ~]# echo 2 > /opt/module/apache-zookeeper-3.5.7-bin/zkData/myid
[root@hadoop103 ~]# echo 3 > /opt/module/apache-zookeeper-3.5.7-bin/zkData/myid
7. 检查各节点myid号确保正确
[root@hadoop101 module]# for i in hadoop101 hadoop102 hadoop103;do ssh $i cat /opt/module/apache-zookeeper-3.5.7-bin/zkData/myid;done

8. 启动集群各节点服务
[root@hadoop101 module]# /opt/module/apache-zookeeper-3.5.7-bin/bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/module/apache-zookeeper-3.5.7-bin/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED[root@hadoop102 module]# /opt/module/apache-zookeeper-3.5.7-bin/bin/zkServer.sh start
