Ambari2.7.4+HDP3.1.4安装 Centos7离线安装

1. 本次安装简单介绍

1.1Ambari

Ambari是一种基于Web的工具，支持Apache Hadoop集群的创建 、管理和监控。

Ambari已支持大多数Hadoop组件，包括HDFS、MapReduce、Hive、Pig、 Hbase、Zookeeper、Sqoop和Hcatalog等。Apache Ambari 支持HDFS、MapReduce、Hive、Pig、Hbase、Zookeepr、Sqoop和Hcatalog等的集中管理。也是5个顶级hadoop管理工具之一。

Ambari 自身也是一个分布式架构的软件，主要由两部分组成：Ambari Server 和 Ambari Agent。简单来说，用户通过 Ambari Server 通知 Ambari Agent 安装对应的软件；Agent 会定时地发送各个机器每个软件模块的状态给 Ambari Server，最终这些状态信息会呈现在 Ambari 的 GUI，方便用户了解到集群的各种状态，并进行相应的维护。

1.2 HDP

HDP是hortonworks的软件栈，里面包含了hadoop生态系统的所有软件项目，比如HBase,Zookeeper,Hive,Pig等等。

1.3 HDP-UTILS

HDP-UTILS是工具类库。

2. Ambari搭建前环境准备

2.1 版本介绍

截止到2020.03.03，Ambari的最新版本为2.7.5，HDP的最新版本为3.1.5

通过 https://supportmatrix.hortonworks.com/ 可以查询Ambari和HDP各个版本支持情况

我这里选择的是2.7.4版本，所以使用的HDP对应版本为3.1.4

slave3（子节点）	192.168.105.193	Compute node	4G	450G

2.5 修改网络配置（所有节点）

用putty或者xshell连接执行

 # cd /etc/sysconfig/network-scripts  

找到ifcfg-en开头，后面的数字由每台机器生成各有不同，直接vi编辑即可

修改前：

修改后：

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
IPADDR=192.168.105.137
NETMASK=255.255.255.0
GATEWAY=192.168.105.1

IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=eno1
UUID=6c053b64-6581-4665-b3fc-c22f79c58848
DEVICE=eno1
ONBOOT=yes

重启网络服务：# service network start

ping一下局域网其他机器 通了即可

3. 系统环境配置

3.1 安装 JDK（所有节点）

Linux自带的jdk或者是通过yum安装的jdk都是openjdk
最好是使用开源的oracle jdk，缺失部分功能，如果直接安装oracle的jdk，第三方的依赖包不会安装，我们这里是通过yum安装openjdk，并同时安装了第三方依赖包，然后卸载openjdk，通过自己来安装oracle的jdk，就能解决依赖问题。

3.1.1 安装openjdk

[root@master ~]# yum -y install java
[root@master ~]# java -version
openjdk version "1.8.0_212"
OpenJDK Runtime Environment (build 1.8.0_212-c061)
OpenJDK 64-Bit Server VM (build 25.212-c061, mixed mode)
[root@master ~]# rpm -qa|grep java
javapackages-tools-3.4.1-11.el7.noarch
java-1.8.0-openjdk-1.8.0.212-0.c061.el7_7.x86_64
python-javapackages-3.4.1-11.el7_7.noarch
tzdata-java-2018d-1.el7_7.noarch
java-1.8.0-openjdk-headless-1.8.0.212-0.c061.el7_7.x86_64

3.1.2卸载OpenJDK

[root@master ~]# rpm -e --nodeps java-1.8.0-openjdk-headless-1.8.0.212-0.c061.el7_7.x86_64
[root@master ~]# rpm -e --nodeps java-1.8.0-openjdk-1.8.0.212-0.c061.el7_7.x86_64

安装和卸载的时候注意一下open jdk的版本号

3.1.3安装之前下好的 OracleJDK （注意文件位置）

[root@master ~]# rpm -ivh jdk-8u201-linux-x64.rpm 
准备中...                          ################################# [100%]

[root@master ~]# javac -version
javac 1.8.0_201

验证安装成功

3.2 修改节点名称（所有节点）

3.2.1 修改/etc/hosts文件（所有节点）

方便通过名称来查找相应节点

[root@master ~]# vi /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1             localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.105.137 master
192.168.105.191 slave1
192.168.105.192 slave2
192.168.105.193 slave3

3.2.2 修改/etc/sysconfig/network（所有节点）

各节点改成相对应的节点名即可

[root@master ~]# vi /etc/sysconfig/network
# Created by anaconda
NETWORKING=yes
HOSTNAME=master

[root@master ~]# hostnamectl set-hostname master
[root@master ~]# hostname
master

接下来通过测试ping各个节点名称是否调通

[root@master ~]# ping slave1
PING slave1 (192.168.105.191) 56(84) bytes of data.
64 bytes from slave1 (192.168.105.191): icmp_seq=1 ttl=64 time=0.320 ms

rtt min/avg/max/mdev = 0.269/0.282/0.320/0.018 ms

3.3 更换所有节点为阿里巴巴yum源（所有节点）

阿里巴巴开发者社区url： https://developer.aliyun.com/mirror/
选择Centos

可直接运行如下

[root@master ~]# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
[root@master ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@master ~]# yum makecache

3.4 同步时间ntp

3.4.1 安装ntp服务（所有节点）

[root@master ~]# yum -y install ntp

启动服务，查看状态并设置开机自启

[root@master ~]# systemctl start ntpd.service
 [root@master ~]# systemctl status ntpd.service
● ntpd.service - Network Time Service
   Loaded: loaded (/usr/lib/systemd/system/ntpd.service; disabled; vendor preset: disabled)

[root@master ~]# systemctl enable ntpd.service

3.5 关闭防火墙（所有节点）

查看防火墙状态

[root@master ~]# systemctl status firewalld.service

关闭防火墙

[root@master ~]# systemctl stop firewalld.service

设置开机不启动

[root@master ~]# systemctl disable firewalld.service

查看是否成功

[root@master ~]# systemctl is-enabled firewalld.service
disabled

3.6 关闭Selinux和THP（所有节点）

3.6.1关闭Selinux

查看Selinux状态

[root@master ~]# sestatus

关闭Selinux，提示没有vim用yum装一个咯或者用vi

[root@master ~]# vim /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

3.6.2关闭THP

查看状态

[root@yum ~]# cat /sys/kernel/mm/transparent_hugepage/defrag 
[always] madvise never
[root@yum ~]# cat /sys/kernel/mm/transparent_hugepage/enabled 
[always] madvise never

关闭THP并给予文件权限

[root@yum ~]# vim /etc/rc.d/rc.local
#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.

touch /var/lock/subsys/local

if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
        echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
        echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi
[root@yum ~]# chmod +x /etc/rc.d/rc.local

3.7 修改文件打开最大限制（所有节点）

设置并查看

[root@master ~]# vim /etc/security/limits.conf 
# End of file 
* soft nofile 65536 
* hard nofile 65536 
* soft nproc 131072 
* hard nproc 131072
 
[root@master ~]# ulimit -Sn 
[root@master ~]# ulimit -Hn  

3.8 SSH无密码登陆（主节点）

回车通过，输入密码等确认通过即可

[root@master ~]# ssh-keygen -t rsa
[root@master ~]# ssh-copy-id slave1
root@slave1's password: 
Number of key(s) added: 1
Now try logging into the machine, with:   "ssh 'slave1'"
and check to make sure that only the key(s) you wanted were added.
[root@master ~]# ssh-copy-id slave2
Are you sure you want to continue connecting (yes/no)? yes
root@slave2's password: 
Number of key(s) added: 1
[root@master ~]# ssh-copy-id slave3
Are you sure you want to continue connecting (yes/no)? yes
root@slave3's password: 
Number of key(s) added: 1
[root@master ~]# ssh-copy-id master
Are you sure you want to continue connecting (yes/no)? yes
root@master's password: 
Number of key(s) added: 1
Now try logging into the machine, with:   "ssh 'master'"
and check to make sure that only the key(s) you wanted were added

测试是否实现无密码登录 ，无输入密码即可通过

[root@master ~]# ssh slave1 date ;ssh slave2 date;ssh slave3 date;ssh master date;
Tue Mar  3 16:32:07 CST 2020
Tue Mar  3 16:32:07 CST 2020
Tue Mar  3 16:32:07 CST 2020
Tue Mar  3 16:32:08 CST 2020

将刚刚创建的秘钥拷出来，后面ambari安装的时候需要上传这个秘钥。创建秘钥是在隐藏文件夹/root/.ssh/下面的，所以需要先把秘钥拷贝到可见区域，然后拷贝到本机上。

[root@master ~]# cd /root/.ssh/
[root@master .ssh]# ls
authorized_keys  id_rsa  id_rsa.pub  known_hosts
[root@master .ssh]# cp id_rsa /root/
[root@master .ssh]# ls /root/
ambari                               
ambari-2.7.4.0-centos7.tar.gz        id_rsa                              
anaconda-ks.cfg      install.sh  jdk-8u201-linux-x64.rpm

到这里我们先reboot重启一下

4. 实现离线安装，更换yum源

4.1 文件目录展示

由于我这里主机已经安装了Nginx，所以文件目录的方式我这里写了两种展示目录的方式 ，4.1.1和4.1.2选择一种即可

4.1.1 http服务方式

[root@master ~]# yum -y install httpd
[root@master ~]# service httpd restart
Redirecting to /bin/systemctl restart httpd.service
[root@master ~]# chkconfig httpd on

安装完成后，会生成 /var/www/html目录（相当于Tomcat的webapps目录）

将之前下的Ambari、HDP、HDP-UTILS三个包放到 /var/www/html 下

[root@master ~]# cd /var/www/html/
[root@master html]# mkdir ambari
拷贝文件到ambari下面
[root@master html]# cd ambari/
[root@master ambari]# ls
ambari-2.7.4.0-centos7.tar.gz   HDP-3.1.4.0-centos7-rpm.tar.gz  HDP-UTILS-1.1.0.22-centos7.tar.gz
[root@master ambari]# tar -zxvf ambari-2.7.4.0-centos7.tar.gz
[root@master ambari]# tar -zxvf HDP-3.1.4.0-centos7-rpm.tar.gz 
[root@master ambari]# mkdir HDP-UTILS
[root@master ambari]# tar -zxvf HDP-UTILS-1.1.0.22-centos7.tar.gz -C HDP-UTILS
[root@master ambari]# rm -rf ambari--2.7.4.0-centos7.tar.gz HDP-2.6.3.0-centos7-rpm.tar.gz HDP-UTILS-1.1.0.22-centos7.tar.gz 
[root@master ambari]# ls
ambari  HDP  HDP-UTILS

4.1.2 nginx服务方式

找到nginx的配置， 在nginx server中的location中增加：

 server {
        listen 8001;
        location / {
            root /www//html/ambari/;
            autoindex on;
            autoindex_localtime on;
            autoindex_exact_size off;
        }
     }

参数说明：
root /data/image/
你需要开启浏览的目录，放访问
http://IP 时候显示的就是/data/image目录下的内容

autoindex_localtime on;
默认为off，显示的文件时间为GMT时间。
改为on后，显示的文件时间为文件的服务器时间

autoindex_exact_size off;
默认为on，显示出文件的确切大小，单位是bytes。
改为off后，显示出文件的大概大小，单位是kB或者MB或者GB

listen 8001;
访问端口号，

[root@master ~]# cd /var/www/
[root@master html]# mkdir ambari
拷贝文件到ambari下面
[root@master html]# cd ambari/
[root@master ambari]# ls
ambari-2.7.4.0-centos7.tar.gz   HDP-3.1.4.0-centos7-rpm.tar.gz  HDP-UTILS-1.1.0.22-centos7.tar.gz
[root@master ambari]# tar -zxvf ambari-2.7.4.0-centos7.tar.gz
[root@master ambari]# tar -zxvf HDP-3.1.4.0-centos7-rpm.tar.gz 
[root@master ambari]# mkdir HDP-UTILS
[root@master ambari]# tar -zxvf HDP-UTILS-1.1.0.22-centos7.tar.gz -C HDP-UTILS
[root@master ambari]# rm -rf ambari--2.7.4.0-centos7.tar.gz HDP-2.6.3.0-centos7-rpm.tar.gz HDP-UTILS-1.1.0.22-centos7.tar.gz 
[root@master ambari]# ls
ambari  HDP  HDP-UTILS

访问 http://192.168.105.137/ambari/ 看是否能访问

4.2 制作本地源

4.2.1 安装本地源制作相关工具（主节点）

[root@master ambari]# yum install yum-utils createrepo yum-plugin-priorities -y
[root@master ambari]#  createrepo  ./

4.2.2 修改文件里面的源地址（主节点）

注意文件路径，以自己为准

[root@master ambari]# vi ambari/centos7/2.7.4.0-118/ambari.repo
#VERSION_NUMBER=2.7.4.0-118
[ambari-2.7.4.0]
#json.url = http://public-repo-1.hortonworks.com/HDP/hdp_urlinfo.json
name=ambari Version - ambari-2.7.4.0

priority=1
[root@master ambari]# cp ambari/centos7/2.7.4.0-118/ambari.repo /etc/yum.repos.d/
[root@master ambari]# vi HDP/centos7/3.1.4.0-315/hdp.repo

enabled=1
priority=1
[root@master ambari]# cp HDP/centos7/3.1.4.0-315/hdp.repo /etc/yum.repos.d/

以上就已经创建好了

使用yum的命令清一下缓存

[root@master ambari]# yum clean all
[root@master ambari]# yum makecache
[root@master ambari]# yum repolist

4.2.3 将创建好的源文件拷贝到子节点（主节点）

[root@master ambari]#cd /etc/yum.repos.d
[root@master yum.repos.d]# scp ambari.repo slave1:/etc/yum.repos.d/
ambari.repo                                                                                        100%  274    24.8KB/s   00:00    
[root@master yum.repos.d]# scp ambari.repo slave2:/etc/yum.repos.d/
ambari.repo                                                                                        100%  274   294.9KB/s   00:00    
[root@master yum.repos.d]# scp ambari.repo slave3:/etc/yum.repos.d/
ambari.repo                                                                                        100%  274   541.7KB/s   00:00    
[root@master yum.repos.d]# scp hdp.repo slave1:/etc/yum.repos.d/
hdp.repo                                                                                           100%  482     603.6KB/s   00:00    
[root@master yum.repos.d]# scp hdp.repo slave2:/etc/yum.repos.d/
hdp.repo                                                                                           100%  482   541.9KB/s   00:00    
[root@master yum.repos.d]# scp hdp.repo slave3:/etc/yum.repos.d/
hdp.repo

5. 安装ambari-server

这里介绍两种模式，一种是默认postgresql数据库的安装方式，这种不推荐生产环境使用，但是在安装中不会出现问题，还有就是mysql方式，这里我们用到的是mysql，大家根据自身选一种即可

无论是用哪种，首先都要安装ambari-server

[root@master yum.repos.d]# yum -y install ambari-server

5.1默认数据库PostgreSQL安装方式（不推荐）（主节点）

5.2 MySql安装方式（主节点）

5.2.1 安装MySql

[root@master ~]# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
[root@master ~]# rpm -ivh mysql-community-release-el7-5.noarch.rpm
[root@master ~]# yum install mysql-community-serve

5.2.2 启动mysql，设置开机启动

[root@master ~]# service mysqld start
[root@master ~]# vi /etc/rc.local
#添加service mysqld start

5.2.3 登录进mysql，初始化设置root密码

[root@master ~]# mysql -uroot 

设置登录密码
mysql> set password for 'root'@'localhost' = password('yourPassword');

添加远程登录用户
mysql> grant all privileges on *.* to 'root'@'%' identified by 'yourPassword';

远程登录
#mysql -uroot -h ip(远程的ip地址) -p

5.2.4登录mysql，执行以下的语句

CREATE DATABASE ambari;  
use ambari;  
CREATE USER 'ambari'@'%' IDENTIFIED BY 'ambari';  
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%';  
CREATE USER 'ambari'@'localhost' IDENTIFIED BY 'ambar';  
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'localhost';

CREATE USER 'oozie'@'master' IDENTIFIED BY 'oozie';  
GRANT ALL PRIVILEGES ON *.* TO 'oozie'@'master';  
FLUSH PRIVILEGES;

5.2.5 建立mysql与ambari-server的jdbc连接

[root@master yum.repos.d]# yum install mysql-connector-java
[root@master yum.repos.d]# ls /usr/share/java
[root@master yum.repos.d]# cp /usr/share/java/mysql-connector-java.jar /var/lib/ambari-server/resources/mysql-jdbc-driver.jar
[root@master yum.repos.d]# vi /etc/ambari-server/conf/ambari.properties
添加server.jdbc.driver.path=/usr/share/java/mysql-connector-java.jar

5.2.6设置ambari-server

如果启动失败 建议查看
日志在/var/log/ambari-server/ambari-server.log里面
重置 ambari-server

[root@master ~]# ambari-server stop
[root@master ~]# ambari-server reset
[root@master ~]# ambari-server setup

如果选择的是mysql方式，就需要先执行上面的语句，然后手动将mysql里面创建的数据库进行删除

[root@master ~]# mysql -uroot -p
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| ambari             |
| hive               |
| oozie              |
| performance_schema |
+--------------------+
rows in set (0.00 sec)
mysql> drop database ambari;
mysql> drop database hive;
mysql> drop database oozie;

如果在安装的过程中出现了错误，又想重新安装，可以在ambari-server开启的情况下，执行下面的语句来移除已安装的包，然后再通过不同的情况选择上面两种方式的一种对ambari-server进行重置

python /usr/lib/python2.6/site-packages/ambari_agent/HostCleanup.py --silent

6. 安装配置部署HDP集群

6.1 登录过程

如果你以上安装成功
输入主机ip：8080则会看到如下界面
账户：admin 密码：admin

5.2 安装向导

登录后点击进入流程

6.2.1 配置及群名字

我这用到的是hadoop

6.2.2 选择版本并修改为本地源地址

放一张机翻的配置

ambari确认过了就next继续了

6.2.3 安装配置

上传之前存好的秘钥文件id_rsa

机翻页面

6.2.4 确认安装ambari的agent

确认安装ambari的agent，并检查出现的问题，这个地方经常出现错误

如图就出现了错误，点击Failed的查看错误日志

像我这里的错误是ambari的8040等端口无法访问的问题，我放开了8000-9000的端口就可以了，我之前也遇到很多其他的问题，具体问题具体分析，多查谷歌，百度，国外的网站更容易解决问题

机翻

检查主机可能会发现之前漏下的问题，比如说我这里防火墙没关他就会出现提示

检查无误，NEXT→通过即可

如果这个步骤失败了错误，记得多看日志，多找问题，如果还不行的话，回档咯

[root@master ~]# # ambari-server stop    #停止命令
[root@master ~]# # ambari-server reset   #重置命令
[root@master ~]# # ambari-server setup   #重新设置 
[root@master ~]# # ambari-server start   #启动命令

6.2.5 大数据服务组件安装

勾选你所需要的

6.2.6 节点分配

6.2.7 分配主从

6.2.8 安装配置

hive和oozie的数据库用户密码填上之前创建好的

如果安装了hive，ooize等，需要修改成我们本地建好的库，jdbc-mysql也要配置好

6.2.9 概况部署

警告这里我这就忽略掉了，后期我们再修复

哈哈，这红的心慌，把他们变绿吧
