安装 ElasticSearch

Docker ElasticSearch

详见 Docker 安装 Elasticsearch、Kibana

Docker Compose 安装

或者 使用 docker compose 安装

[root@localhost ~]# docker-compose version
bash: docker-compose: 未找到命令...

docker compose 下载地址:https://github.com/docker/compose/releases/download/v2.16.0/docker-compose-linux-x86_64

将 docker-compose-Linux-x86_64 传到 /usr/local/bin 目录下,并改名为 docker-compose
image

[root@localhost ~]# chmod +x /usr/local/bin/docker-compose
[root@localhost ~]# docker-compose version
Docker Compose version v2.16.0

Docker Compose ElasticSearch

在目录 /opt/elasticsearch (目录自定义)下创建 docker-compose.yml 文件内容如下

version: "7.9.3"
services:
  elasticsearch:
    image: elasticsearch:7.9.3
    restart: always
    container_name: elasticsearch
    ports:
      - 9200:9200
    volumes:
      - /opt/elasticsearch/logs:/usr/share/elasticsearch/logs
  kibana:
    image: kibana:7.9.3
    restart: always
    container_name: kibana
    ports:
      - 5601:5601
    environment:
      - elasticsearch url=http://172.16.3.88:9200
      - I18N_LOCALE=zh-CN
    depends_on:
      - elasticsearch

执行命令

[root@localhost ~]# cd /opt/elasticsearch
[root@localhost elasticsearch]# pwd
/opt/elasticsearch
#安装
[root@localhost elasticsearch]# docker-compose up -d

安装 IK Analysis

ES 默认分词器,对汉字的分词不太友好

下载 ik 分词器插件

找到对应的 Elasticsearch 版本,这里用的:7.9.3,将地址复制到讯雷里下,直接下的话下不动

方式一:在容器中下载安装

先把zip下载下来。放到任意一台服务器(直接github上下载多数会失败)

# 查看 ES 的容器ID
[root@localhost ~]# docker ps -a

方式二:将文件上传至容器,进行安装

将 ik 文件传至服务器

将 ik 复制到容器,并安装

重启容器

docker restart xxx

如果不重启会报:failed to find global analyzer [ik_smart]

{
    "error": {
        "root_cause": [
            {
                "type": "illegal_argument_exception",
