《Elasticsearch技术解析与实战》Chapter 1.2 Elasticsearch安装

1. 下载安装

1.1 下载

https://www.elastic.co/downloads/elasticsearch
下载 https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.7.0.tar.gz

1.2 解压

tar -zxvf elasticsearch-6.7.0.tar.gz

1.3 运行

cd elasticsearch-6.7.0
bin/elasticsearch

1.4 检验

curl http://localhost:9200  或者浏览器访问
{
    "name": "q9sdES9",
    "cluster_name": "docker-cluster",
    "cluster_uuid": "6klEi4d0Q6y0LC3YNYVXTQ",
    "version": {
        "number": "5.5.0",
        "build_hash": "260387d",
        "build_date": "2017-06-30T23:16:05.735Z",
        "build_snapshot": false,
        "lucene_version": "6.6.0"
    },
    "tagline": "You Know, for Search"
}

2. Docker部署

官方文档 : https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html

2.1 拉取镜像

docker pull docker.elastic.co/elasticsearch/elasticsearch:5.5.1

2.2 启动容器

docker run -p 9200:9200 9300:9300 -e "http.host=0.0.0.0" -e “transport.host=0.0.0.0" --name elasticsearch_5.5.0 -d docker.elastic.co/elasticsearch/elasticsearch:5.5.0

2.3 修改配置

进入到容器中 : docker exec -it elasticsearch_5.5.0 /bin/bash
修改jvm配置 : vi /config/jvm.options
            -Xms2g  —>  -Xms512m
            -Xmx2g  —>  -Xmx512m
    修改小一些,服务器内存有限😂

2.4 重启容器,查看是否成功

http://服务器ip:9200
{
    "name": "q9sdES9",
    "cluster_name": "docker-cluster",
    "cluster_uuid": "6klEi4d0Q6y0LC3YNYVXTQ",
    "version": {
        "number": "5.5.0",
        "build_hash": "260387d",
        "build_date": "2017-06-30T23:16:05.735Z",
        "build_snapshot": false,
        "lucene_version": "6.6.0"
    },
    "tagline": "You Know, for Search"
}
此处集群的名称为 docker-cluster, 可以自行修改 : vi /config/elasticsearch.yml
