Elasticsearch 入门（一）使用docker-compose 部署ELK

docker建议使用镜像源

编辑docker配置文件 vim /etc/docker/daemon.json

{
            "registry-mirrors": ["http://hub-mirror.c.163.com"]
}

docker 安装 elasticsearch

找到elasticsearch官方镜像

https://hub.docker.com/_/elasticsearch

docker pull

docker pull elasticsearch:7.7.0

network

docker network create esnetwork

docker run

docker run -d --name elasticsearch --net eswork -v /root/essearch/plugins:/plugins -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.7.0

测试是否可以使用

打开浏览器 http://yourip:9200/

• Elasticsearch 的默认账户为 elastic 默认密码为 changeme

安装 kibana

找到kibana官方镜像

https://hub.docker.com/_/kibana

docker pull

docker pull kibana:7.7.0

docker run

docker run -d --name kibana --net esnetwork -p 5601:5601 kibana:7.7.0

测试是否可以使用

打开浏览器 http://yourip:5601/app/kibana#/home

• docker network inspect eswork
• 172.18.0.2

配置 kibana

使用 docker exec -it kibana bash
cd ./config/kibana.yml
编辑 kibana

# Default Kibana configuration for docker target
server.name: kibana
server.host: "0"
elasticsearch.hosts: [ "http://172.18.0.2:9200" ]
monitoring.ui.container.elasticsearch.enabled: true
elasticsearch.username: "elastic"
elasticsearch.password: "changeme"
i18n.locale: "zh-CN"

docker image prune -a -f

安装 Filebeat

• https://hub.docker.com/_/filebeat
• docker pull elastic/filebeat:7.7.0
• docker run --name filebeat --net eswork elastic/filebeat:7.7.0 setup -E setup.kibana.host=http://172.18.0.3:5601 -E output.elasticsearch.hosts=["http://172.18.0.2:9200"]

配置 filebeat.docker.yml

filebeat.config:
  modules:
    path: ${path.config}/modules.d/*.yml
    reload.enabled: false

filebeat.autodiscover:
  providers:
    - type: docker
      hints.enabled: true

processors:
- add_cloud_metadata: ~

output.elasticsearch:
  hosts: '${ELASTICSEARCH_HOSTS:172.18.0.2:9200}'
  username: '${ELASTICSEARCH_USERNAME:}'
  password: '${ELASTICSEARCH_PASSWORD:}'
  

使用 docker-compose 部署

• cd /usr/share/essearch
• 创建并编辑 docker-compose.yml
