docker 搭建 ElasticSearch

1、拉取镜像

docker pull elasticsearch:8.8.1

2、在机器本地新建文件夹并赋予权限

mkdir -p /home/elasticsearch/config

mkdir -p /home/elasticsearch/data

mkdir -p /home/elasticsearch/plugins

chmod 777 /home/elasticsearch/config

chmod 777 /home/elasticsearch/data

chmod 777 /home/elasticsearch/plugins

3、运行一个临时容器

docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:8.8.1

4、将容器里的config文件夹的东西拷贝到宿主机上

docker cp elasticsearch:/usr/share/elasticsearch/config /home/elasticsearch

5、删除临时容器

docker stop elasticsearch
docker rm -f elasticsearch

6、修改elasticsearch.yml文件

7、启动容器

docker run \
--restart=always \
--name es \
--privileged=true \
-p 9200:9200 \
-p 9300:9300 \
-v /home/elasticsearch/config:/usr/share/elasticsearch/config \
-v /home/elasticsearch/data:/usr/share/elasticsearch/data \
-v /home/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
-e ES_JAVA_OPTS="-Xms512m -Xmx512m" \
-e "discovery.type=single-node" \
-d elasticsearch:8.8.1

8、es访问界面
