This article will explain in detail how to deploy ambari in docker. The content of the article is of high quality, so the editor shares it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

1.docker deployment ambari

① centos7 does not have its own yum tool

Apt-get install yum-y

② install git

Yum-y install git

③ pull remote warehouse

Git clone https://gitee.com/which-ly/docker-ambari-2.7.3.git

④ installation begins

Cd docker-ambari-2.7.3

Cd ambari-base-local

Wget-O local.repo http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.7.3.0/ambari.repo

Cd..

Cd ambari-server-local

Wget-O local.repo http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.7.3.0/ambari.repo

Cd..

# make an image

. / scripts/build-image.sh

# start locally

. / scripts/create-local.sh

⑤ view container

# View the running container

Docker ps

# get web ip

Docker inspect-f'{{range .NetworkSettings.Networks}} {{.IPAddress}} {{end}} 'amb-server

# visit the ambari interface

Http://ambari-server (IP): 8080

# check the ip of other nodes

Docker inspect container id | grep-I ip

two。 Configure ssh secret-free login

The ip of my three containers here are

172.17.0.2 (amb-server)

172.17.0.3 (amb1)

172.17.0.4 (amb2)

① modifies hostname

# go to each container to modify the hostname

Sudo hostnamectl set-hostname node1

172.17.0.2 (amb-server)-> node3

172.17.0.3 (amb1)-> node1

172.17.0.4 (amb2)-> node2

② modifies the hosts file and can directly ping the name.

# enter each container separately

Docker exec-it amb-server / bin/bash

Vi / etc/hosts

172.17.0.2 node3

172.17.0.3 node1

172.17.0.4 node2

# comment out at the same time:

# 172.17.0.3 amb1.service.consul amb1

# 172.17.0.4 amb2.service.consul amb2

③ generation key

First execute the instructions on each of the three nodes: ssh-keygen, and then press enter until the end. At this point, you can find that idrsa (private key) and idrsa.pub (public key) are generated under the / root/.ssh/ folder, which are the generated key pairs.

④ public key sharing

To synchronize the public key to all nodes, you need to enter the root password. All three nodes set the root password to ambari123.

Sudo passwd

Send your own public key to other nodes, including yourself. The instructions are as follows:

Ssh-copy-id node1

Ssh-copy-id node2

Ssh-copy-id node3

⑤ configure ambari basic repo (already configured, go directly to 3)

Find the yum repo address of hdp3.1.4 from the following address

Http://public-repo-1.hortonworks.com/HDP/hdp_urlinfo.json

Yum repo address of hdp-3.1.4:

Http://public-repo-1.hortonworks.com/HDP/centos7/3.x/updates/3.1.4.0/HDP-3.1.4.0-315.xml

Open the repo to see hdp, hdp-gpl, and hdp-utils

3. Secondary repo configuration

# enter each container and do the following

Cd / etc/yum.repos.d/

Cp backup_repo/CentOS-Base.repo.

4. Create a cluster

Click: LAUNCH INSTALL WIZARD

Name: idc

Select HDP3.1

The next step is to enter the private key of the machine where the ambari-server resides, so that ambari-server can deploy the component to other nodes

Docker exec-it amb-server / bin/bash

Cd / root/.ssh

Id_rsa

Only node1 and node2 can be added.

Next, install the service according to the project requirements.
