地址

操作系统

root密码

Master1

10.1.0.30

Centos 7.7

 Root@bidsum1

Master2

10.1.0.105

Centos 7.7

2 SSH免密登录配置

ssh-keygen

cat .ssh/*.pub > .ssh/authorized_keys

scp -r .ssh root@10.1.0.30:/root/

scp -r .ssh root@10.1.0.105:/root/

3 主机名IP映射配置

在master 机器上执行如下命令

vi /etc/hosts

192.168.217.130 hdp-0001

192.168.217.131 hdp-0002

192.168.217.132 hdp-0003

scp /etc/hosts root@hdp-0002:/etc/hosts

scp /etc/hosts root@hdp-0003:/etc/hosts

4 关闭及禁止防火墙

systemctl stop firewalld

systemctl disable firewalld

5 配置阿里yum源(可选)

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

yum makecache

6 开启时钟同步

yum install -y ntp

systemctl enable ntpd

systemctl start ntpd

7 关闭SELinux

vi /etc/sysconfig/selinux

#修改以下内容

SELINUX=disabled

8 安装mysql数据库

mysql服务安装在master节点,也可选择其他节点或机器。

具体步骤如下:

8.1数据库安装

wget http://repo.mysql.com/mysql57-community-release-el7-8.noarch.rpm

yum install mysql-server

[root@master ~]# service mysqld  start

[root@master ~]# grep "password" /var/log/mysqld.log

[root@master ~]# mysql -u root -p

Enter password:

mysql>set global validate_password_policy=LOW;

mysql> set password = password("mysql@Edmp.com");

mysql> grant all privileges on *.* to root@"%" identified by " mysql@Edmp.com" ;

mysql> flush privileges;

8.2安装成功后,创建ambari数据库及用户

#进入mysql shell

mysql -uroot –p

#创建ambari用户

create database ambari character set utf8 ; 

CREATE USER 'ambari'@'%'IDENTIFIED BY 'ambari123';

GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%';

FLUSH PRIVILEGES;

#创建hive用户

create database hive character set utf8 ; 

CREATE USER 'hive'@'%'IDENTIFIED BY 'hive123';

GRANT ALL PRIVILEGES ON *.* TO 'hive'@'%';

FLUSH PRIVILEGES;

#创建oozie用户

create database oozie character set utf8 ; 

CREATE USER 'oozie'@'%'IDENTIFIED BY 'oozie123';

GRANT ALL PRIVILEGES ON *.* TO 'oozie'@'%';

FLUSH PRIVILEGES;

9 安装JDK

9.1解压安装包并配置环境变量

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

9.2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、配置本地yum库

1 服务安装配置

yum install yum-utils createrepo

yum install httpd

service httpd start

2 磁盘挂载

磁盘文件系统可用ext4或者xfs,挂载时需添加noatime选项

mkdir /data

vi /etc/fstab

   /dev/vdb /data xfs defaults,noatime 0 0

mkfs -t xfs /dev/vdb

mount /dev/vdb /data

3下载镜像包,解压到指定目录

操作系统

版本

库名称

tar -zxvf HDP-GPL-2.6.5.0-centos7-gpl.tar.gz -C /var/www/html/ambari/

 

三、安装配置ambari Server

1 配置ambari 的yum源(在master节点)

wget  -nv  http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.5.0.3/ambari.repo -O /etc/yum.repos.d/ambari.repo

wget -nv http://public-repo-1.hortonworks.com/HDP/centos7/2.x/

updates/2.6.0.3/hdp.repo -O /etc/yum.repos.d/hdp.repo

2 修改ambari.repo配置信息

 

#VERSION_NUMBER=2.5.0.3-7

[ambari-2.5.0.3]

name=ambari Version - ambari-2.5.0.3

baseurl=http://10.1.0.30/ambari/ambari/centos7

gpgcheck=0

gpgkey=http://10.1.0.30/ambari/ambari/centos7/2.x/updates/2.5.0.3/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins

enabled=1

priority=1

 

3 执行ambari server安装

yum install ambari-server

4 安装mysql-java驱动

yum install –y mysql-connector-java.noarch

找到/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 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

 

[root@master yum.repos.d]# 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)

 

数据库操作

[root@master ~]# mysql -u root -p

Enter password:

mysql> use ambari;

Database changed

mysql> source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql

Query OK, 0 rows affected (0.00 sec)

 

6 服务启停

启动:ambari-server start

停止:ambari-server stop

启动成功后可以通过浏览器访问管理界面。

URL: 192.168.217.130:8080(IP为master节点IP)

用户名:admin 密码:admin

四、HDP集群部署

1 登录ambari server 管理界面

1.在浏览器打开http://192.168.217.130:8080

2.输入用户名密码  默认admin/admin

 

2 进入集群安装向导

 

3 输入集群名称

建议设置为EDMP,标信数据管理平台简称

 

4 选择hdp版本

点击HDP-2.6,选择上传文件

 
   


在HDP/centos7/2.6.4.0-91/HDP-2.6.4.0-91.xml文件基础上,修改baseurl,修改完后如下:

选择增加版本、上传修改后的版本文件。

增加版本完成后,直接下一步

 

5 确认主机列表(并上传id_rsa文件)

 

 

6 主机注册、主机环境检查

  ERROR 2021-02-20 00:17:28,352 NetUtil.py:96 - EOF occurred in violation of protocol (_ssl.c:618)

ERROR 2021-02-20 00:17:28,352 NetUtil.py:97 - SSLError: Failed to connect. Please check openssl library versions.

 

 

这一步会出现一些问题,具体解决方案在第六部分安装过程中出现的问题中查找

7 选择安装部署组件

 
   


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

 

8 分配服务角色

 

 
   


9 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。

9.1 HDFS

 
   


修改3个数据盘路径

 

 
   


9.2 HIVE

 
   


修改元数据库类型及地址,填写账号密码hive/hive123

9.3 oozie

填写元数据库账号密码,修改访问地址oozie/oozie123,路径参考hive

9.4 zookeeper

修改数据存放路径

 

 
   


9.5 ambari Metrics/ smartsence

设置账号密码,默认为admin/admin

附:暂时修改了以下属性,具体配置信息可根据实际情况后续相应修改

3 输入namenode ha serverid

 

六 安装过程中出现的问题

安装过程中排查问题具体思路:2个路径,第1个为安装页面message目录,点击蓝色进度信息跳转查看;第二个ambari-server后台日志,具体路径为

1)UID错误问题

具体报错信息如下

# 修改文件:/var/lib/ambari-server/resources/stacks/HDP/2.0.6/hooks/before-ANY/files/changeToSecureUid.sh

[root@manager ~]# vim /var/lib/ambari-server/resources/stacks/HDP/2.0.6/hooks/before-ANY/files/changeToSecureUid.sh

function find_available_uid() {

 for ((i=8001; i<=9000; i++))

 do

   grep -q $i /etc/passwd

   if [ "$?" -ne 0 ]

   then

    newUid=$i

    break

   fi

 done

}

 

# 修改原来的  for ((i=1001; i<=2000; i++)) 为  for ((i=8001; i<=9000; i++))

# 8001,9000可以取值为暂时未使用的UID,可以使用id UID验证UID是否被使用,找一段未使用的UID即可

修改完之后需要重启ambari服务

修改了ambari脚本之后,需要执行以下步骤重启ambari

  • 删除ambari-agent缓存:rm -rf /var/lib/ambari-agent/cache/
  • 重启ambari-serverambari-server restart
  • 重启ambari-agentambari-agent restart

 

2)8080端口报错

报错现象:

Ambari Agent host cannot reach Ambari Server 'localhost:8080'.

错误原因:

客户端调用setupAgent.py函数, ambari-server所在IP传参失败,从而导致了问题的发生。

解决办法:

找到文件:/usr/lib/ambari-server/lib/ambari_server/setupAgent.py

手动修改ambari-server hostname

160   expected_hostname = onlyargs[0]
161   passPhrase = onlyargs[1]
162   #hostname = onlyargs[2]
163   hostname = "192.168.31.150"
164   projectVersion = None

3)SSL HTTPS连接错误

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
  security]标签下面增加一项
[security]
force_https_protocol=PROTOCOL_TLSv1_2
