**1、安装docker-compose** ~~~ sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose ~~~ ~~~ sudo chmod +x /usr/local/bin/docker-compose ~~~ ~~~ sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose ~~~ ~~~ docker-compose --version ~~~ **2、elasticsearch** ~~~ docker pull docker.elastic.co/elasticsearch/elasticsearch:6.4.0 ~~~ ~~~ vim /etc/sysctl.conf ​ vm.max_map_count=262144 ​ vim /etc/security/limits.conf ​ soft nofile 65536 hard nofile 65536 ~~~ **3、创建文件和目录** ~~~ mkdir /home/docker/elasticsearch -p ​ cd /home/docker/elasticsearch ​ mkdir config ​ vim elasticsearch.yml ​ cd /home/docker/elasticsearch ​ vim docker-compose.yml ​ mkdir data ~~~ **4、elasticsearch.yml** ~~~ cluster.name: "docker-cluster" node.name: "search-node1" network.host: 0.0.0.0 network.publish_host: 172.16.3.64 ​ # minimum_master_nodes need to be explicitly set when bound on a public IP # # set to 1 to allow single node clusters # # Details: https://github.com/elastic/elasticsearch/pull/17288 discovery.zen.minimum_master_nodes: 1 discovery.zen.ping.unicast.hosts: ["172.16.3.63:9300", "172.16.3.64:9300"] ~~~ **5、docker-compose.yml** ~~~ version: '2.2' services: elasticsearch:   image: docker.elastic.co/elasticsearch/elasticsearch:6.4.0   container_name: elasticsearch   environment:     - cluster.name=docker-cluster     - bootstrap.memory_lock=true     - "ES_JAVA_OPTS=-Xms512m -Xmx512m"   ulimits:     memlock:       soft: -1       hard: -1   network_mode: host   volumes:     - /home/docker/elasticsearch/data:/usr/share/elasticsearch/data     - /home/docker/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml ~~~ **6、在每个服务器的docker-compose.yml 同级目录下同时执行 docker-compose up –d 命令，根据服务器性能，大概等待1分钟左右，两个节点的集群就创建成功了，当然可以通过执行以下命令查看启动状态：** ~~~ docker-compose up –d docker logs elasticsearch -f ~~~ **7、查看集群的所有节点：** ~~~ curl 172.16.232.107:9200/_cat/nodes?v ~~~
