Elasticsearch安装

docker pull elasticsearch:7.4.2

创建需要挂载的目录

> mkdir -p /mydata/elasticsearch/config
>
> mkdir -p /mydata/elasticsearch/data
>cd /mydata/elasticsearch/config
> echo "http.host : 0.0.0.0" >> /mydata/elasticsearch/config/elasticsearch.yml
查看是否创建成功
cat elasticsearch.yml

安装ElasticSearch容器

 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

启动异常：
elasticsearch.yml配置文件的 `:` 两边需要添加空格

还有就是访问的文件权限问题：

chmod -R 777 /mydata/elasticsearch/

然后我们就可以启动容器了
docker elasticsearch star

docker start 容器编号

然后测试访问：http://192.168.1.137:9200

docker update --restart=always elasticsearch
