1. 下载es镜像

   docker pull elasticsearch:7.4.2

2. 安装es可视化工具 两个版本需保持一致

   docker pull kibana:7.4.2

3. 创建本地es配置文件夹和数据文件夹 ```shell mkdir -p /mydata/elasticsearch/config mkdir -p /mydata/elasticsearch/data

   配置es外部任意ip可访问

   echo “http.host:0.0.0.0”>> /mydata/elasticsearch/config/elasticsearch.yml docker run —name elasticsearch -p 9200:9200 -p 9300:9300 \ -e “discovery.type=single-node” \ -e ES_JAVA_OPTS=”-Xms64m -Xmx128m” \ -v /mydata/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \ -v /mydata/elasticsearch/data:/usr/share/elasticsearch/data \ -v /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins \ -d elasticsearch:7.4.2

映射9200 9300端口

配置es启动模式为单机模式

配置es运行内存 实际开发中需要放大

挂载confif data plugins插件目录到本机

-d后台启动

5. 安装kibana
```shell
docker run --name kibana -e ELASTICSEARCH_HOSTS=http://192.168.56.175:9200 -p 5601:5601 -d kibana:7.4.2

1. 安装ik分词器 版本需要和es版本一致 此处都用7.4.2

   #下载地址
   https://github.com/medcl/elasticsearch-analysis-ik/releases?after=v7.5.0&page=5
   #选择7.4.2版本下载
   wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.4.2/elasticsearch-analysis-ik-7.4.2.zip
   #解压并重命名
   unzip elasticsearch-analysis-ik-7.4.2.zip -d ik
   #赋予读写权限
   chmod -R 777 ik/
   #安装完毕 可进去容器查看
   docker restart es容器

   测试效果
   

2. 自定义扩展分词库 ->配置分词库地址 ->安装nginx配置访问分词库文件

   #1.安装nginx   mydata/文件夹下新建nginx/conf目录
   docker run -p 80:80 --name nginx -d nginx:1.10
   此命令如果本地没有镜像的话会先去下载镜像并启动
   #2.移动nginx/etc下的目录到 本地nginx/conf下
   docker container cp nginx:/etc/nginx .
   #3.删除nginx
   docker stop nginx
   docker rm nginx
   #4.重新启动nginx 并配置映射
   docker run -p 80:80 --name nginx \
   -v /mydata/nginx/html:/usr/share/nginx/html \
   -v /mydata/nginx/logs:/var/log/nginx \
   -v /mydata/nginx/conf:/etc/nginx \
   -d nginx:1.10
   #5.配置es分词库
   mkdir es
   vi fenci.txt
   #6.配置es分词库地址
   cd /pligins/config
   vi IKAnalyzer.cfg.xml
   #7.重启es
   docker restart elasticsearch

   
   
   
   

   FAQ

3. 启动几秒后又自动挂了 ```shell

   查看日志

   docker logs —tail 200 elasticsearch

“Caused by: java.nio.file.AccessDeniedException: /usr/share/elasticsearch/data/nodes”

出现此错误是因为data文件夹没有权限

chmod -R 777 /mydata/elasticsearch/

改为所有用户都有读写曲线

2. 关于es重新定义内存问题
```shell
#1.先停止之前的es
docker stop 4914
#2.删除之前的es
docker rm 4914
#3.重新启动es分配对应内存  文件夹指定原来的文件夹(保证原有数据不丢失)
docker run --name elasticsearch -p 9200:9200 -p 9300:9300 \
-e "discovery.type=single-node" \
-e ES_JAVA_OPTS="-Xms64m -Xmx512m" \
-v /mydata/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
-v /mydata/elasticsearch/data:/usr/share/elasticsearch/data \
-v /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
-d elasticsearch:7.4.2
