docker一键部署elasticsearch搜索服务器只要3分钟

Posted 2021-04-21 docker核心技术中文网

什么是elasticsearch？

Elasticsearch是一个实时的分布式搜索和分析引擎。它可以帮助你用前所未有的速度去处理大规模数据。

ElasticSearch是一个基于Lucene的搜索服务器。它提供了一个分布式多用户能力的全文搜索引擎，基于RESTful web接口。Elasticsearch是用Java开发的，并作为Apache许可条款下的开放源码发布，是当前流行的企业级搜索引擎。设计用于云计算中，能够达到实时搜索，稳定，可靠，快速，安装使用方便。

主要优点：

1. Elasticsearch是分布式的。不需要其他组件，分发是实时的，被叫做”Push replication”。

2. Elasticsearch 完全支持 Apache Lucene 的接近实时的搜索。

3. 处理多租户（multitenancy）不需要特殊配置，而Solr则需要更多的高级设置。

4. Elasticsearch 采用 Gateway 的概念，使得完备份更加简单。

5. 各节点组成对等的网络结构，某些节点出现故障时会自动分配其他节点代替其进行工作。

   
   

   废话不多说请看dockerfile代码吧

目录结构如下：

        image: zailing/elasticsearch
        container_name: elasticsearch
        hostname: elasticsearch
        privileged: true
        read_only: false
        tty: false
        network_mode: "bridge"

        ulimits:
            nofile:
                soft: 102400
                hard: 102400
            memlock:

                hard: -1

        ports:
            - "123.56.116.82:2228:22"
            - "9100:9100"
            - "9200:9200"

            - /data/docker/elasticsearch/logs:/opt/elasticsearch/logs
            - /data/docker/elasticsearch/conf:/opt/elasticsearch/config

最好只需要           docker-compose up -d 即可完成部署喔
