【ambari-部署】Ambari2.6.2 HDP2.6.5 大数据集群搭建

Ambari 2.6.2 中
HDFS-2.7.3 YARN-2.7.3 HIVE-1.2.1 HBASE-1.1.2 ZOOKEEPER-3.4.6 SPARK-2.3.0

注：本文基于root用户操作

一、安装环境准备

操作系统 centos7.5
hdc-data1：192.168.163.51
hdc-data2：192.168.163.52
hdc-data3：192.168.163.53
【安装环境准备每台集群机器一样的操作，或者使用scp远程拷贝】

1、主机名IP映射配置

FQDN：(Fully Qualified Domain Name)全限定域名：同时带有主机名和域名的名称。（通过符号“.”）
例如：主机名是bigserver,域名是mycompany.com,那么FQDN就是bigserver.mycompany.com。

vi /etc/hosts
#添加如下地址映射及FQDN（ambari注册时需要）
192.168.163.51 hdc-data1 hdc-data1.hadoop
192.168.163.52 hdc-data2 hdc-data2.hadoop
192.168.163.53 hdc-data3 hdc-data3.hadoop

2、SSH免密登录配置

ssh-keygen
ssh-copy-id -i ~/.ssh/id_rsa.pub root@hdc-data1
ssh-copy-id -i ~/.ssh/id_rsa.pub root@hdc-data2
ssh-copy-id -i ~/.ssh/id_rsa.pub root@hdc-data3

3、关闭及禁止防火墙

systemctl stop firewalld.service
systemctl disable firewalld.service

4、关闭SELinux

SELinux(Security-Enhanced Linux) 是美国国家安全局（NSA）对于强制访问控制的实现，是 Linux历史上最杰出的新安全子系统。NSA是在Linux社区的帮助下开发了一种访问控制体系，在这种访问控制体系的限制下，进程只能访问那些在他的任务中所需要文件。

vi /etc/sysconfig/selinux
#修改以下内容
SELINUX=disabled

image.png

5、开启NTP服务

yum install -y ntp
systemctl enable ntpd 
systemctl start ntpd

6、安装JDK

下载地址：https://www.oracle.com/technetwork/cn/java/javase/downloads/jdk8-downloads-2133151-zhs.html

通过文件传输上传到服务器，这里不可用wget直接下载。

mkdir -p /opt/java
tar -zxvf jdk-8u181-linux-x64.tar.gz -C /opt/java/
vi /etc/profile

export JAVA_HOME=/opt/java/jdk1.8.0_181
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$PATH:$JAVA_HOME/bin

远程分发到其他服务器

scp -r /opt/java/jdk1.8.0_181/ root@hdc-data2:/opt/java/
scp -r /opt/java/jdk1.8.0_181/ root@hdc-data3:/opt/java/

scp /etc/profile root@hdc-data2:/etc/
scp /etc/profile root@hdc-data3:/etc/

source /etc/profile

二、Ambari安装

1、制作Ambari本地yum源

选取一台机器即可，在此选择hdc-data1。

https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.2.0/bk_ambari-installation/content/ch_obtaining-public-repos.html

需要下载资源安装包如下：

wget http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.6.2.0/ambari-2.6.2.0-centos7.tar.gz
wget http://public-repo-1.hortonworks.com/HDP/centos7/2.x/updates/2.6.5.0/HDP-2.6.5.0-centos7-rpm.tar.gz
wget http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.22/repos/centos7/HDP-UTILS-1.1.0.22-centos7.tar.gz
wget http://public-repo-1.hortonworks.com/HDP-GPL/centos7/2.x/updates/2.6.5.0/HDP-GPL-2.6.5.0-centos7-gpl.tar.gz

1.1 安装 Apache HTTP 服务器

yum install httpd -y
#开启服务并设置开机自启动
systemctl start httpd.service
systemctl enable httpd.service

1.2 安装制作yum源工具

yum install yum-utils createrepo

1.3 创建http服务器

http根目录默认是即/var/www/html/

mkdir -p /var/www/html/ambari
#cd /var/www/html/ambari
#将下载好的安装包上传并解压
tar xvf HDP-2.6.5.0-centos7-rpm.tar.gz -C /var/www/html/ambari
tar xvf ambari-2.6.2.0-centos7.tar.gz -C /var/www/html/ambari
tar xvf HDP-UTILS-1.1.0.22-centos7.tar.gz -C /var/www/html/ambari
tar xvf HDP-GPL-2.6.5.0-centos7-gpl.tar.gz -C /var/www/html/ambari

# 删除压缩包
rm -rf ambari-2.6.2.0-centos7.tar.gz
rm -rf HDP-2.6.5.0-centos7-rpm.tar.gz
rm -rf HDP-UTILS-1.1.0.22-centos7.tar.gz
rm -rf HDP-GPL-2.6.5.0-centos7-gpl.tar.gz

1.4 配置ambari、HDP、HDP-UTILS的本地源

#yum install wget -y
cd /etc/yum.repos.d/
wget http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.6.2.0/ambari.repo
wget http://public-repo-1.hortonworks.com/HDP/centos7/2.x/updates/2.6.5.0/hdp.repo
wget http://public-repo-1.hortonworks.com/HDP-GPL/centos7/2.x/updates/2.6.5.0/hdp.gpl.repo

编辑ambari.repo，修改baseurl和gpgkey

[root@hdc-data1 yum.repos.d]# vi ambari.repo 

#VERSION_NUMBER=2.6.2.0-155
[ambari-2.6.2.0]

编辑hdp.gpl.repo，修改baseurl和gpgkey

[root@hdc-data1 yum.repos.d]# vi hdp.gpl.repo 

#VERSION_NUMBER=2.6.5.0-292
[HDP-GPL-2.6.5.0]
name=HDP-GPL Version - HDP-GPL-2.6.5.0

分发到其他机器

scp /etc/yum.repos.d/ambari.repo root@hdc-data2:/etc/yum.repos.d/
scp /etc/yum.repos.d/ambari.repo root@hdc-data3:/etc/yum.repos.d/
scp /etc/yum.repos.d/hdp.repo root@hdc-data2:/etc/yum.repos.d/
scp /etc/yum.repos.d/hdp.repo root@hdc-data3:/etc/yum.repos.d/
scp /etc/yum.repos.d/hdp.gpl.repo root@hdc-data2:/etc/yum.repos.d/
scp /etc/yum.repos.d/hdp.gpl.repo root@hdc-data3:/etc/yum.repos.d/

每台机器yum配置

yum clean all
yum makecache
yum list

2、安装Mysql数据库

Ambari安装会将安装等信息写入数据库，建议使用MariaDB数据库，也可以不安装而使用默认数据库PostgreSQL

2.1 安装及初始化设置

[root@hdc-data1 ~]# yum install mariadb-server
[root@hdc-data1 ~]# systemctl start mariadb
[root@hdc-data1 ~]# systemctl enable mariadb
[root@hdc-data1 ~]# mysql_secure_installation

#首先是设置密码，会提示先输入密码
Enter current password for root (enter for none):<–初次运行直接回车
#设置密码
Set root password? [Y/n] <– 是否设置root用户密码，输入y并回车或直接回车
New password: <– 设置root用户的密码
Re-enter new password: <– 再输入一次你设置的密码
#其他配置
Remove anonymous users? [Y/n] <– 是否删除匿名用户，回车
Disallow root login remotely? [Y/n] <–是否禁止root远程登录,回车,
Remove test database and access to it? [Y/n] <– 是否删除test数据库，回车
Reload privilege tables now? [Y/n] <– 是否重新加载权限表，回车

【可选】修改mysql端口（生产环境安全考虑）
查看端口

2.2 安装完成后创建ambari数据库及用户

#进入mysql shell
mysql -uroot -p

create database ambari character set utf8 ;  
CREATE USER 'ambari'@'%'IDENTIFIED BY 'ambari123';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%';
FLUSH PRIVILEGES;

如果要安装Hive，创建Hive数据库和用户

create database hive character set utf8 ;  
CREATE USER 'hive'@'%'IDENTIFIED BY 'hive123';
GRANT ALL PRIVILEGES ON *.* TO 'hive'@'%';
FLUSH PRIVILEGES;

如果要安装Oozie，创建Oozie数据库和用户

create database oozie character set utf8 ;  
CREATE USER 'oozie'@'%'IDENTIFIED BY 'oozie123';
GRANT ALL PRIVILEGES ON *.* TO 'oozie'@'%';
FLUSH PRIVILEGES;

3、安装 ambari

yum install ambari-server

4、下载mysql驱动

http://central.maven.org/maven2/mysql/mysql-connector-java/5.1.40/
将mysql-connector-Java.jar复制到/usr/share/java目录下

mkdir /usr/share/java
cp mysql-connector-java-5.1.40.jar /usr/share/java/mysql-connector-java.jar

将mysql-connector-java.jar复制到/var/lib/ambari-server/resources目录下

cp mysql-connector-java-5.1.40.jar /var/lib/ambari-server/resources/mysql-jdbc-driver.jar

5、编辑/etc/ambari-server/conf/ambari.properties，添加如下内容

server.jdbc.driver.path=/usr/share/java/mysql-connector-java.jar
#【可选】修改默认8080端口
#client.api.port=18080

6、ambaria初始化

#设置mysql驱动
ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar 
ambari-server setup

完整初始化如下：

[root@hdc-data1 ~]# ambari-server setup

说明：
1：提示是否自定义设置。输入：y 或 按回车继续
2：ambari-server 账号。使用root（推荐）用户直接回车 若使用ambari用户输入：ambari
3：设置JDK,输入数字3，选客户端安装jdk，如果服务器可以访问外网，则可以选1，自动下载jdk1.8，默认下载的安装目录是/usr/java/default
4：如果上面选择3自定义JDK,则需要设置JAVA_HOME
5：输入：y 或 按回车继续
6：输入“y“，进行数据库的高级配置
7：输入“3“，选择mysql/mariadb数据库
8：设置数据库的配置参数：host,port,database,username,password。根据实际情况输入，如果和括号内相同，则可以直接回车。若端口改6033则输入port:6033。
9：输入：y 或 按回车继续
（若设置更改，可以再次执行ambari-server setup进行设置）

7、将Ambari数据库脚本导入到数据库

#用Ambari用户（上面设置的用户）登录mysql
mysql -u ambari -p
use ambari;
source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql

image.png

8、启动Ambari

ambari-server start

image.png

浏览器访问：http://hdc-data1:8080/ 默认登录用户：admin，密码：admin

9、WEBUI配置

image.png

创建集群名称

image.png

选择HDP版本和选择本地仓库

image.png

配置HDP的Repository

image.png

输入集群节点host(FQDN)和Ambari节点SSH的私钥

image.png

等待ambari-agents注册

image.png

若报错

image.png

image.png

【遇到问题 Confirm Hosts】
注册ambari-agents时failed
NetUtil.py:96 - EOF occurred in violation of protocol (_ssl.c:579)
SSLError: Failed to connect. Please check openssl library versions.
解决：如下第三个方案，/etc/ambari-agent/conf/ambari-agent.ini文件只有执行该步骤进行注册才生成。修改后点击“Retry Failed”按钮，等待注册成功进入下一步。

# 1、yum upgrade openssl 已是最新本版，未解决
# 2、vi /etc/python/cert-verification.cfg 修改 verify=disable，未解决
[https]
#verify=platform_default
verify=disable
# 3、最后解决方案 在ambari-agent的配置文件/etc/ambari-agent/conf/ambari-agent.ini
 在 ［security］标签下面增加一项
[security]
force_https_protocol=PROTOCOL_TLSv1_2

image.png

选择安装组件，（最小化安装HDFS+YARN+MAPREDUCE2+Ambari Metrics+SmartSense+ZooKeeper+Hbase）不必要的组件可以暂时不安装节省安装时间，后续可以再添加安装组件

image.png

image.png

实际部署时需按规划设计进行分配（注意：Hbase HA 的话在Hbase Master 点击后面的小绿色+号，添加standby master）：

image.png

工作节点角色分配(生产环境全勾了)

image.png

组件配置信息修改
通常数据目录修改到/data/目录下，有红色信息提示的组件表示要输入相应的账号密码。以下示例，可根据自己的实际情况配置。

HDFS

image.png

image.png

HIVE,若数据库端口修改按实际填写

image.png

Oozie

image.png

Zookeeper

等待安装完成

image.png

直到所有节点成功安装完成才能进行下一步操作

image.png

最终结果界面类似如下：

image.png

安装完成！

三、后续操作

操作前最好先将集群打个快照备份

1、HDFS启用HA(高可用)

参考http://www.louisvv.com/archives/1490.html

step1：关闭hbase、hive相关服务

image.png

step2:在HDFS选择Enable NameNode HA

image.png

step3:输入namenode ha serverid

image.png

step4:默认，进入下一步

image.png

step5:预览，直接进入下一步

image.png

step6:创建checkpoint，根据提示执行下列命令

image.png

根据提示在server1执行下列两条命令

image.png

命令执行完成方可进入下一步

image.png

step7:等待配置进程完成

image.png

step8:Journalnode初始化

image.png

需要在原NameNode节点执行下列命令

sudo su hdfs -l -c 'hdfs namenode -initializeSharedEdits'

image.png

step9: 启动组件，进入下一步

image.png

step10:初始化元数据，

sudo su hdfs -l -c 'hdfs zkfc -formatZK'

image.png

注意在新添加的NameNode节点上操作

sudo su hdfs -l -c 'hdfs namenode -bootstrapStandby'

image.png

image.png

step11:等待所有服务重启，完成
