Amabri2.6.0、hdp2.6.1安装

Amabri2.6.0、hdp2.6.1在centos7下安装

一、环境准备

1、修改各个节点主机名

vi /etc/hostname

2、配置主节点hosts

vi /etc/hosts

2、配置免密

（1）手动配置

主节点执行：

ssh-keygen -t rsa

ssh-copy-id $host（第1步中的各个节点名称）

（2）脚本配置

3、同步hosts

主节点执行：scp /etc/hosts $host:/etc/ （$host各从节点名称）

4、关闭防火墙、selinux

各个节点执行：

systemctl stop firewalld.service

systemctl disable firewalld.service

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

重启：reboot

5、安装httpd

查看httpd是否已安装：rpm -qa |grep httpd

安装：rpm -ivh httpd/*.rpm

6、镜像本地yum源配置

新建文件夹：mkdir /var/www/html/iso

将安装镜像中的文件全部复制到iso文件夹下

这里写图片描述

启动httpd：systemctl start httpd.service

验证：浏览器打开http://ip/iso/

编辑：vi /etc/yum.repos.d/local.repo

local.repo同步到其他节点

yum clean all

yum list update

yum makecache

yum repolist

7、检查更改最大文件描述符

ulimit -Sn

ulimit -Hn

如果\<10000，运行ulimit -n 10000

二、依赖检查

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（所有节点）

Centos7自带python2.7.5即可。

（Anaconda3.6 还原为系统自带2.7：bashrc
注释掉anaconda的环境变量，退出用户，重新登录。）

2、JDK （所有节点）

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）检测并卸载之前安装的版本：

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）安装

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

（3）验证

java -version

若找不到java，需配置环境变量：

在/etc/profile添加

source /etc/profile

3、MySQL5.6 （主节点）

（1）下载

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

（2）查询并卸载系统自带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）安装perl、net-tools

yum install perl

yum install net-tools

（4）安装

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

密码在/root/.mysql_secret

service mysql start

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

执行mysql_secure_installation

这里写图片描述

（5）设置用户

验证登陆MySQL控制台：mysql -uroot –p

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

flush privileges;

创建ambari数据库及用户：

create database ambari character set utf8 ;

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

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

FLUSH PRIVILEGES;

创建hive数据库及用户：

create database hive character set utf8 ;

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

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

FLUSH PRIVILEGES;

创建oozie数据库及用户：

create database oozie character set utf8 ;

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

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

FLUSH PRIVILEGES;

（6）设置MySQL为开机启动

chkconfig mysql on;

chkconfig –list mysql;

查看是否如同如下结果

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

（7）安装：

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安装

hdp、hdp-utils下载地址

https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.0.0/bk_ambari-installation/content/hdp_26_repositories.html

ambari下载地址

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

1、准备本地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/

重启httpd：systemctl restart httpd.service

验证：
