随记——docker中安装es

拉取镜像失败解决方案

环境： centos8

一、安装es

1. 拉取镜像

docker pull elasticsearch:7.4.2

2. 创建目录

mkdir -p /data/elasticsearch/config
mkdir -p /data/elasticsearch/data
echo "http.host : 0.0.0.0" >> /data/elasticsearch/config/elasticsearch.yml
# 添加权限，否则会报错:Caused by: java.nio.file.AccessDeniedException: /usr/share/elasticsearch/data/nodes
chmod -R 777 /data/elasticsearch/

4. 创建并启动容器

docker run --name elasticsearch -p 9200:9200 -p 9300:9300 \-e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms64m -Xmx512m" -v /data/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /data/elasticsearch/data:/usr/share/elasticsearch/data -v /data/elasticsearch/plugins:/usr/share/elasticsearch/plugins -d elasticsearch:7.4.2

5. 访问地址http://ip:9200/

#返回这些数据表示安装成功
{"name":"79d717c28f76","cluster_name":"elasticsearch","cluster_uuid":"B4acoHXUTDiPT5oebGvhqQ","version":{"number":"7.4.2","build_flavor":"default","build_type":"docker","build_hash":"2f90bbf7b93631e52bafb59b3b049cb44ec25e96","build_date":"2019-10-28T20:40:44.881551Z","build_snapshot":false,"lucene_version":"8.2.0","minimum_wire_compatibility_version":"6.8.0","minimum_index_compatibility_version":"6.0.0-beta1"},"tagline":"You Know, for Search"}

二、安装分词器

下载对应版本的分词器，地址：https://github.com/medcl/elasticsearch-analysis-ik

# 1、上传安装包到 /data/elasticsearch/plugins 目录下
# 2、解压
unzip -d elasticsearch-analysis-ik-7.4.2 elasticsearch-analysis-ik-7.4.2.zip
rm -rf elasticsearch-analysis-ik-7.4.2.zip
# 3、进入容器
docker exec -it elasticsearch /bin/bash
# 4、到bin目录下执行命令，表示安装成功
[root@79d717c28f76 bin]# ./elasticsearch-plugin list
elasticsearch-analysis-ik-7.4.2

三、安装Kibanan

1. 拉取镜像

docker pull kibana:7.4.2

2. 创建并启动容器

docker run --name kibana -e ELASTICSEARCH_HOSTS=http://es服务ip:9200 -p 5601:5601 -d kibana:7.4.2

3. 访问测试http://ip:5601,启动慢，需要等一会
4. 异常处理

# 查看日志
docker logs 容器id
#发现异常
unable to revive connection:http://elasticsearch:9200
#执行命令进入容器
docker exec -it f57a14f92aaf /bin/bash
#进入config目录
cd config/
#修改es地址配置
vi kibana.yml 
elasticsearch.hosts: [ "http://elasticsearch:9200" ]
#退出容器
exit
#重启容器
docker restart 容器id
