Docker image address: https://www.docker.elastic.co/#

Install docker-compose first, and install docker-compose using pip, because pip can automatically correspond to version problems

Install pip

Yum-y install epel-releaseyum-y install python-pip

Confirm the version

Pip-version

Update pip

Pip install-upgrade pip

Install docker-compose

Pip install docker-compose

View version

Docker-compose version download elasticsearchdocker pull docker.elastic.co/elasticsearch/elasticsearch:7.1.1 download logstashdocker pull docker.elastic.co/logstash/logstash:7.1.1 download kibanadocker pull docker.elastic.co/kibana/kibana:7.1.1

Write the docker-compose.yml file and create a new elkDocker directory under the / opt/ directory

Mkdir / opt/elkDocker

Enter the elkDocker directory

Cd / opt/elkDocker

Create a new docker-compose.yml file

Vi docker-compose.ymlversion: '2.2'services:elasticsearch:image: docker.elastic.co/elasticsearch/elasticsearch:7.1.1container_name: elasticsearch7.1.1environment:- discovery.type=single-node- "ES_JAVA_OPTS=-Xms512m-Xmx512m" volumes:- esdata:/usr/share/elasticsearch/datahostname: elasticsearchrestart: alwaysports:- 9200 elasticsearch7.1.1environment:- discovery.type=single-node- 9200-9300:9300kibana:image: docker.elastic.co/kibana/kibana:7.1.1container_name: kibana7.1.1environment:- elasticsearch.hosts=http: / / elasticsearch:9200hostname: kibanadepends_on:- elasticsearchrestart: alwaysports:- "5601 logstash:image: docker.elastic.co/logstash/logstash:7.1.1container_name: logstash7.1.1hostname: logstashrestart: alwaysdepends_on:- elasticsearchports:- 9600 Visa 9600-5044:5044volumes:esdata:driver: local

Execute in the same directory as the yml file

Docker-compose up-d

Done indicates success. Docker-compose logs checks the log (outputs the logs of the three elk services respectively) and executes docker ps to see the running status of the three services.

Enter http://IP:5601/ in the browser

It should be noted that the situation is as follows:

1. Do not download the official image of docker, it is best to use the image in the official warehouse of elastic

two。 If the startup is unsuccessful, comment out the other two first and try to run one service separately.

3.logstash needs to listen to elasticsearch service, otherwise logstash will stop automatically.

4.logstash and kibana do not need to set the environment variable of the associated elasticsearch. The official website document says that if it is a docker image, it has a default setting.

5. If you change the service name or port, remember to change the default settings.

Let's start installing ElasticSearch-Head

Pull ElasticSearch-Head image

Docker pull mobz/elasticsearch-head:5

Run the ElasticSearch-Head container

Docker run-d-name es_admin-p 9100V 9100 mobz/elasticsearch-head:5

Enter http://IP:9100 in the browser

Note: if an error occurs when running the ElasticSearch-Head container, it is as follows:

Docker: Error response from daemon: Conflict. The container name "/ es_admin" is already in use by container "a9a2a5c74ab3b2dc42c2260fad0b0b1dd6e7c768a5cfb2ddbb121eb2946a370c". You have to remove (or rename) that container to be able to reuse that name.

Then execute docker container ls-all to view the CONTAINER ID and then execute the docker rm id number

Then re-execute docker run-d-name es_admin-p 9100 mobz/elasticsearch-head:5

Note: the reason why Elasticsearch-head can not connect to Elasticsearch and the solution

1. Modify the Gruntfile.js file under elasticsearch-head, as follows:

Connect: {server: {options: {hostname: '0.0.0.0, port: 9100, base:'., keepalive: true}

two。 Modify the elasticsearch-head_site\ app.js file. Change this.base_uri to the following value.

This.base_uri = this.config.base_uri | | this.prefs.get ("app-base_uri") | | "http://localhost:9200";"

Edit configuration file

Vim / etc/elasticsearch/elasticsearch.yml

Add the following two items

Http.cors.enabled: truehttp.cors.allow-origin: "*"

Then restart elasticsearch and access http://localhost:9100/ to successfully connect to port 9200
