Elasticsearch 安装（Docker版）

1、下载镜像文件

#存储和检索数据
docker pull elasticsearch:7.4.2
#可视化检索数据
docker pull kibana:7.4.2

2、创建实例

1、创建数据卷映射目录及相关配置

mkdir -p /mydata/elasticsearch/config
mkdir -p /mydata/elasticsearch/data
echo "http.host: 0.0.0.0" >>/mydata/elasticsearch/config/elasticsearch.yml

2、运行容器 Elasticsearch

docker run  --restart always --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 

查看Docker 启动日志

docker logs   容器id前三位/或者容器名

踩坑点一

es报错:Exception in thread “main“ SettingsException[Failed to load settings from [elasticsearch.yml]]

elasticsearch.yml  中

http.host: 0.0.0.0 分号后要空一格

踩坑点二

es:报错 "stacktrace": ["org.elasticsearch.bootstrap.StartupException: ElasticsearchException[failed to bind service]; nested: AccessDeniedException[/usr/share/elasticsearch/data/nodes];",

数据卷映射目录赋予权限即可

chmod -R 777 /mydata/elasticsearch

重启容器

Docker restart 容器id前三位/或者容器名

成功安装

3、运行容器 kibana

docker run --restart always --name kibana \
-e ELASTICSEARCH_HOSTS=http://192.168.56.10:9200 -p 5601:5601 \
-d kibana:7.4.2

成功安装
