This article mainly explains the "steps to install Ambari2.2.1 and HDP2.4 under centos6". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "the steps to install Ambari2.2.1 and HDP2.4 under centos6".

1. First of all, download their installation packages, do not try to yum, very slow, the best way is to create local resources to install.

Http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/2.4.0.0/HDP-2.4.0.0-centos6-rpm.tar.gz

Http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.20/repos/centos6/HDP-UTILS-1.1.0.20-centos6.tar.gz

Http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.2.1.0/ambari-2.2.1.0-centos6.tar.gz

two。 Set up a local resource library and set up a hdp directory under var/www/html. If you don't have it, install httpd yum install httpd to install and decompress the three resources, then transfer them to the hdp directory, and then restart the httpd service. Use the following three addresses to test whether you can access the URL, and then prepare three files. Hdp.repo,ambari.repo,hdp-util.repo do not follow the official instructions. That will report an error. I will put mine out, change the address according to it, and then copy these three files to the / etc/yum.repos.d/ directory of all the machines in the cluster.

Next, I will post their content.

Hdp.repo

[HDP-2.3.0.0] name=HDP Version-HDP-2.3.0.0baseurl= http://10.0.71.15/hdp/HDP/centos6/2.x/updates/2.3.0.0gpgcheck=1gpgkey=http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/2.3.0.0/RPM-GPG-KEY/RPM-GPG-KEY-Jenkinsenabled=1priority=1

Ambari.repo

Hdp-util.repo

3. Preparation before installation

(1) set ssh to log in automatically, which can be done by referring to the one in which ssh automatically logs in. The URL is http://www.cnblogs.com/cenyuhai/p/3280668.html.

(2) set ntpd to start automatically, and all machines

Chkconfig-level 5 ntpd on service ntpd start

(3) disable selinux, all machines

Vi / etc/sysconfig/selinux set selinux=disabled

(4) set time synchronization, all machines

Cp / usr/share/zoneinfo/Asia/Shanghai / etc/localtime # sets the time zone to Beijing time, this is Shanghai, because there is only Shanghai in the centos. Ntpdate us.pool.ntp.org # time synchronization

If you don't have ntpdate installed, you can yum yum install-y ntpdate

Join the scheduled task and synchronize the clock every 10 minutes

Crontab-e

Paste the following content into it and save it.

0-59 take 10 * / usr/sbin/ntpdate us.pool.ntp.org | logger-t NTP

(5) modify the / etc/hosts file for all machines and set it as follows:

192.168.1.133 hadoop.Master192.168.1.134 hadoop.SlaveT1192.168.1.135 hadoop.SlaveT2

4. Modify the configuration file, all machines

Yum install yum-plugin-priorities vi / etc/yum/pluginconf.d/priorities.conf # is set to the following content [main] enabled=1 gpgcheck=0

5. Install a custom mysql service

Yum install-y mysql-server

After installation, log in with your root account and execute the following command

Create database hive; grant all on hive.* TO 'hive'@'%' IDENTIFIED BY' hive'; create database oozie DEFAULT CHARACTER SET utf8; grant all on oozie.* TO 'oozie'@'%' IDENTIFIED BY' oozie'

If mysql is also installed on a machine in the cluster, and the service is also installed on that machine. For example, if I have a hive service on my hadoop.SlaveT1, and if mysql is also on it, I will not be able to connect and I need to run the following command

Grant all on hive.* TO 'hive'@'hadoop.SlaveT1' IDENTIFIED BY' hive'

5. Install the ambari service

Yum install-y epel-release yum install ambari-server

/ / download jdk linux x64 by yourself. You can see which version you can see when you execute ambari-server setup and put it under / var/lib/ambari-server/resources, so that it won't download itself and the speed will be slow.

Ambari-server setup

My ambari database account password is all ambari.

Start the ambari service ambari-server start after installation

Access address ip:8080 username password admin/admin

Question:

Mysql cannot find the driver

Yum install mysql-connector-java

two。 To use mysql database, you need to import the database and build tables manually.

Mysql > create database ambari character set utf8

Mysql > use ambari

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

Mysql > grant all privileges on ambari.* to ambari@'%' identified by 'ambari'
