# docker部署ElasticSearch(ElasticSearch、elasticsearch-head、kibana、ik 分词器)
## 开放端口
- 9200 ----ElasticSearch对外端口
- 9100 ----elasticsearch-head端口
- 5601 ----端口

## 安装elasticsearch7.6.1

```
cat /proc/sys/vm/max_map_count   
sysctl -w vm.max_map_count=262144
mkdir -p /opt/docker/es/es/plugins
docker pull elasticsearch:7.6.1
docker run --name elasticsearch -d -v /opt/docker/es/es/plugins:/usr/share/elasticsearch/plugins -e ES_JAVA_OPTS="-Xms512m -Xmx512m -Duser.timezone=GMT+08" -e "discovery.type=single-node" -p 9200:9200 -p 9300:9300 elasticsearch:7.6.1
```
做完以上操作es就安装完毕,为以下其他服务，需开启跨域

**进入容器**

```
 docker exec -it elasticsearch /bin/bash
```
修改config/elasticsearch.yml，在底部添加以下内容

```
http.cors.enabled: true 
http.cors.allow-origin: "*"
```
**重启容器**

```
docker restart elasticsearch 
```
输入以下网站显示以下内容说明成功运行
http://IP地址:9200/

## 安装elasticsearch-head

```
docker pull mobz/elasticsearch-head:5
docker run -d --name elasticsearch-head -p 9100:9100 mobz/elasticsearch-head:5
```
做到此步骤，部署完成，但无法访问，需要做以下步骤


```
mkdir -p /opt/docker/es/es-head
docker cp elasticsearch-head:/usr/src/app/_site/vendor.js /opt/docker/es/es-head/
cd /opt/docker/es/es-head/
```

修改vendor.js内容
将
contentType: "application/x-www-form-urlencoded" 
改成 contentType: "application/json;charset=UTF-8"
var inspectData = s.contentType === "application/x-www-form-urlencoded" 
改成 var inspectData = s.contentType === "application/json;charset=UTF-8"

**重启容器**
```
docker cp /opt/docker/es/es-head/vendor.js  elasticsearch-head:/usr/src/app/_site
docker restart elasticsearch-head
```
输入ip:9100测试，结果如下

## 安装kibana

```
docker pull kibana:7.5.1
mkdir -p /opt/docker/es/kibana/config/
cd  /opt/docker/es/kibana/config/
```
配置 kibana.yml

```
server.name: kibana
server.host: "0"
elasticsearch.hosts: [ "http://ip地址:9200" ]
xpack.monitoring.ui.container.elasticsearch.enabled: true
i18n.locale: "zh-CN"
```
> elasticsearch.hosts 需配置以上安装的elasticsearch地址

**启动容器**

```
docker run -d 
  --name=kibana 
  --restart=always 
  -p 5601:5601 
  -v /opt/docker/es/kibana/config/kibana.yml:/usr/share/kibana/config/kibana.yml 
  kibana:7.5.1
```
测试安装

## 安装 ik 分词器

```
cd /opt/docker/es/es/plugins
mkdir ik 
```
**下载ik 分词器 zip**
> https://download.csdn.net/download/qq_41974343/86264108

将ik分词器压缩包elasticsearch-analysis-ik-7.6.1.zip上传至/opt/docker/es/es/plugins/ik目录下
**执行一下操作**

```
unzip elasticsearch-analysis-ik-7.6.1.zip
rm -rf elasticsearch-analysis-ik-7.6.1.zip
docker restart elasticsearch
docker exec -it elasticsearch /bin/bash
```

**测试安装**
命令
```
elasticsearch-plugin list

```
看到以下内容则安装成功
