Docker安装配置Elasticsearch

#### 1、拉取elasticsearch镜像，和kibana可视化镜像
```
docker pull elasticsearch:7.17.0
docker pull kibana:7.17.0
```

#### 2、创建和容器内配置文件映射的文件
```
mkdir -p /gsafety/docker/elasticsearch/config 
mkdir -p /gsafety/docker/elasticsearch/data
mkdir -p /gsafety/docker/elasticsearch/plugins
```

#### 3、向外部配置文件中添加配置
```
echo "http.host: 0.0.0.0" >> /gsafety/docker/elasticsearch/config/elasticsearch.yml
```

#### 4、保证挂载文件权限
```
chmod -R 777 /gsafety/docker/elasticsearch/
```

#### 5、启动elasticsearch容器
```
docker run --name myelasticsearch -p 9200:9200 -p 9300:9300 \
-e "discovery.type=single-node" \
-e ES_JAVA_OPTS="-Xms64m -Xmx512m" \
-v /gsafety/docker/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
-v /gsafety/docker/elasticsearch/data:/usr/share/elasticsearch/data \
-v /gsafety/docker/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
-d elasticsearch:7.17.0
```

#### 6、启动kibana容器
```
docker run --name mykibana -e ELASTICSEARCH_HOSTS=http://10.97.129.36:9200 -p 5601:5601 -d kibana:7.17.0
```

#### 7、测试，在9200、5601端口开通访问权限的前提下。
```
浏览器访问：http://ip地址:9200
linux服务器上用命令访问：curl 用户名:密码@localhost:9200

浏览器访问：http://ip地址:5601
```

#### 8、安装ik分词器。
创建ik插件目录
```
mkdir /gsafety/docker/elasticsearch/plugins/ik
```
下载ik压缩包上传到 /gsafety/docker/elasticsearch/plugins/ik 目录下解压。然后重启es容器即可
```
https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.17.0/elasticsearch-analysis-ik-7.17.0.zip
```
#### 9、测试ik分词器
可直接在服务器上测试，如果es已经开启的访问验证，则访问是需要用户名和密码
```
curl -X POST -H "Content-Type: application/json" http://用户名:密码@localhost:9200/_analyze -d '{"analyzer": "ik_smart", "text": "中华人民共和国国歌"}'
```
如果没开启验证
```
curl -X POST -H "Content-Type: application/json" http://localhost:9200/_analyze -d '{"analyzer": "ik_smart", "text": "中华人民共和国国歌"}'
```
