Docker学习笔记六、安装elasticsearch

一、镜像准备

docker pull elasticsearch:7.9.2

二、创建主机目录 

# 1.创建目录

mkdir -p /data/elasticsearch/{config,data,plugins}

# 2.开放目录权限

chmod -R 777 /data/elasticsearch/

# 3.创建配置文件

echo -e "cluster.name: \"docker-cluster\"\nnetwork.host: 0.0.0.0">>/data/elasticsearch/config/elasticsearch.yml

三、创建elasticsearch容器

docker run --name elasticsearch -p 9200:9200 \  -p 9300:9300 \  -e "discovery.type=single-node" \  -e ES_JAVA_OPTS="-Xms128m -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:7.9.2 

四、安装中文分词器（可选）

# 进入容器

docker exec -it elasticsearch /bin/bash

 # 安装分词器（注意版本要匹配）

./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.9.2/elasticsearch-analysis-ik-7.9.2.zip

 五、时区同步(容器默认UTC时区)

 # 1.复制主机localtime

docker cp /usr/share/zoneinfo/Asia/Shanghai elasticsearch:/etc/localtime

# 2.进入容器

docker exec -it elasticsearch /bin/bash

# 3.同步jvm时区

echo "Asia/Shanghai" > /etc/timezone

# 4.重启容器

docker restart elasticsearch

六、开机自启

# docker开机自启

systemctl enable docker.service

# tomcat容器开机自启

docker update --restart=always elasticsearch
