Amabri2.6.0、hdp2.6.1安裝

Amabri2.6.0、hdp2.6.1在centos7下安裝

一、環境準備

1、修改各個節點主機名

vi /etc/hostname

2、配置主節點hosts

vi /etc/hosts

2、配置免密

（1）手動配置

主節點執行：

ssh-keygen -t rsa

ssh-copy-id $host（第1步中的各個節點名稱）

（2）腳本配置

3、同步hosts

主節點執行：scp /etc/hosts $host:/etc/ （$host各從節點名稱）

4、關閉防火牆、selinux

各個節點執行：

systemctl stop firewalld.service

systemctl disable firewalld.service

sed -i \”s;enforcing;disabled;g\” /etc/selinux/config

重啓：reboot

5、安裝httpd

查看httpd是否已安裝：rpm -qa |grep httpd

安裝：rpm -ivh httpd/*.rpm

6、鏡像本地yum源配置

新建文件夾：mkdir /var/www/html/iso

將安裝鏡像中的文件全部複製到iso文件夾下

啓動httpd：systemctl start httpd.service

驗證：瀏覽器打開http://ip/iso/

編輯：vi /etc/yum.repos.d/local.repo

local.repo同步到其他節點

yum clean all

yum list update

yum makecache

yum repolist

7、檢查更改最大文件描述符

ulimit -Sn

ulimit -Hn

如果\<10000，運行ulimit -n 10000

二、依賴檢查

https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.1/bk_support-matrices/content/ch_matrices-ambari.html#ambari_stack

1、Python 2.7.X（所有節點）

Centos7自帶python2.7.5即可。

（Anaconda3.6 還原爲系統自帶2.7：bashrc
註釋掉anaconda的環境變量，退出用戶，重新登錄。）

2、JDK （所有節點）

HDP 2.6.1 JDK Support

JDK	Version
Open Source	JDK8†
	JDK7† , deprecated
Oracle	JDK 8, 64-bit (minimum JDK 1.8.0_77), default
	JDK 7, 64-bit (minimum JDK 1.7_67), deprecated

（1）檢測並卸載之前安裝的版本：

rpm -qa |grep java

rpm -e java-1.8.0-openjdk-1.8.0.151-1.b12.el7_4.x86_64 –nodeps

rpm -e java-1.8.0-openjdk-headless-1.8.0.151-1.b12.el7_4.x86_64 –nodeps

（2）安裝

rpm -ivh jdk-8u77-linux-x64.rpm

（3）驗證

java -version

若找不到java，需配置環境變量：

在/etc/profile添加

source /etc/profile

3、MySQL5.6 （主節點）

（1）下載

http://mirrors.sohu.com/mysql/MySQL-5.6/

（2）查詢並卸載系統自帶mariadb

rpm -qa | grep mariadb -i

rpm -e MariaDB-common-10.2.13-1.el7.centos.x86_64
MariaDB-compat-10.2.13-1.el7.centos.x86_64
MariaDB-client-10.2.13-1.el7.centos.x86_64
MariaDB-server-10.2.13-1.el7.centos.x86_64 –nodeps

（3）安裝perl、net-tools

yum install perl

yum install net-tools

（4）安裝

tar -xvf MySQL-5.6.36-1.el7.x86_64.rpm-bundle.tar

rpm -ivh MySQL-server-5.6.36-1.el7.x86_64.rpm

密碼在/root/.mysql_secret

service mysql start

rpm -ivh MySQL-client-5.6.36-1.el7.x86_64.rpm

執行mysql_secure_installation

（5）設置用戶

驗證登陸MySQL控制檯：mysql -uroot –p

grant all privileges on *.* to root\@’%’ identified by “123456”;

flush privileges;

創建ambari數據庫及用戶：

create database ambari character set utf8 ;

CREATE USER ‘ambari’\@’%’ IDENTIFIED BY ‘ambari’;

GRANT ALL PRIVILEGES ON *.* TO ‘ambari’\@’%’ IDENTIFIED BY ‘ambari’;

FLUSH PRIVILEGES;

創建hive數據庫及用戶：

create database hive character set utf8 ;

CREATE USER ‘hive’\@’%’ IDENTIFIED BY ‘hive’;

GRANT ALL PRIVILEGES ON *.* TO ‘hive’\@’%’ IDENTIFIED BY ‘hive’;

FLUSH PRIVILEGES;

創建oozie數據庫及用戶：

create database oozie character set utf8 ;

CREATE USER ‘oozie’\@’%’ IDENTIFIED BY ‘oozie’;

GRANT ALL PRIVILEGES ON *.* TO ‘oozie’\@’%’ IDENTIFIED BY ‘oozie’;

FLUSH PRIVILEGES;

（6）設置MySQL爲開機啓動

chkconfig mysql on;

chkconfig –list mysql;

查看是否如同如下結果

mysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off

（7）安裝：

rpm -ivh MySQL-shared-compat-5.6.36-1.el7

rpm -ivh MySQL-shared-5.6.36-1.el7

（file /usr/share/mysql/charsets/README from install of
mariadb-libs-1:5.5.52-1.el7.x86_64 conflicts with file from package
MySQL-server-5.6.36-1.el7.x86_64）

三、ambari安裝

hdp、hdp-utils下載地址

ambari下載地址

https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.0.0/bk_ambari-installation/content/ambari_repositories.html

1、準備本地yum源

mkdir -p /var/www/html/ambari/HDP-UTILS-1.1.0.21

tar -zxf HDP-UTILS-1.1.0.21-centos7.tar.gz -C
/var/www/html/ambari/HDP-UTILS-1.1.0.21

tar -zxf HDP-2.6.1.0-centos7-rpm.tar.gz -C /var/www/html/ambari/

tar -zxf ambari-2.6.0.0-centos7.tar.gz -C /var/www/html/ambari/

重啓httpd：systemctl restart httpd.service

驗證：
