elasticsearch docker 安装

方式1：

docker run -d --name elasticsearch85 -p 0.0.0.0:9702:9200 -p 0.0.0.0:9703:9300 -e "discovery.type=single-node"  -e "xpack.security.enabled=true" -e "ELASTIC_PASSWORD=yourpasswd" --restart=unless-stopped docker.elastic.co/elasticsearch/elasticsearch:8.5.1

这种方式生成的所有用户密码都一样，适用于快速部署测试验证。

方式2：生产部署

前期准备：

# 1.创建es 相关挂载目录
mkdir -p /home/mqq/elasticsearch/elasticsearch_docker_map_path/config/
mkdir -p /home/mqq/elasticsearch/elasticsearch_docker_map_path/data
mkdir -p/home/mqq/elasticsearch/elasticsearch_docker_map_path/plugins
 
# 2. /home/mqq/elasticsearch/elasticsearch_docker_map_path/config/ 下创建文件
vim elasticsearch.yml
 
cluster.name: "docker-cluster"
network.host: 0.0.0.0
# 允许远程访问
http.host: 0.0.0.0 
http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization
xpack.security.enabled: true
 
# 3. 设置目录权限，否则会报错
chmod +x elasticsearch.yml
# 设置为目录 777 权限
chmod -R 777 /mydata/elasticsearch

对应的docker_compose.yml文件配置如下：

version: "3"

networks:
  elasticsearch8:
    external: false
services:
  elasticsearch:
    image: elasticsearch:8.5.1
    container_name: elasticsearch851
    environment:
      - discovery.type=single-node
      - ES_JAVA_OPTS=-Xms1024m -Xmx1024m
    ports:
      - 9201:9200
      - 9301:9300
    networks:
      - elasticsearch8
    volumes:
      - /home/mqq/elasticsearch/elasticsearch_docker_map_path/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
      - /home/mqq/elasticsearch/elasticsearch_docker_map_path/data:/usr/share/elasticsearch/data
      - /home/mqq/elasticsearch/elasticsearch_docker_map_path/plugins:/usr/share/elasticsearch/plugins

 启动容器：

sudo docker-compose -f docker_compose.yml up -d

# 配置访问es密码步骤

docker exec -it 容器id /bin/bash
# 配置密码
./bin/elasticsearch-setup-passwords interactive
