创建Elasticsearch容器

创建所需文件

mkdir -p /mydata/elasticsearch/config

mkdir -p /mydata/elasticsearch/data

echo "http.host: 0.0.0.0">>/mydata/elasticsearch/config/elasticsearch.yml

注意：http.host: 0.0.0.0 冒号后有一空格。

文件夹赋权

chmod -R 777 elasticsearch/

命令启动

docker run --name elasticsearch -p 9200:9200 \ -p 9300:9300 \ -e "discovery.type=single-node" \ -e ES_JAVA_OPTS="-Xms64m -Xmx128m" \ -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:7.7.0

参数说明

--name elasticsearch：将容器命名为 elasticsearch -p 9200:9200：将容器的9200端口映射到宿主机9200端口 -p 9300:9300：将容器的9300端口映射到宿主机9300端口，目的是集群互相通信 -e "discovery.type=single-node"：单例模式 -e ES_JAVA_OPTS="-Xms64m -Xmx128m"：配置内存大小 -v /mydata/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml：将配置文件挂载到宿主机 -v /mydata/elasticsearch/data:/usr/share/elasticsearch/data：将数据文件夹挂载到宿主机 -v /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins：将插件目录挂载到宿主机(需重启) -d elasticsearch:7.7.0：后台运行容器，并返回容器ID

docker-compose启动

version: '2' services: elasticsearch: container_name: elasticsearch image: elasticsearch:7.7.0 ports: - "9200:9200" volumes: - /mydata/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml - /mydata/elasticsearch/data:/usr/share/elasticsearch/data - /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins environment: - "ES_JAVA_OPTS=-Xms64m -Xmx128m" - "discovery.type=single-node" - "COMPOSE_PROJECT_NAME=elasticsearch-server" restart: always

查看容器

docker ps -a
