1分钟使用docker构建elasticsearch集群

1.下载elasticsearch镜像

docker pull elasticsearch:5.6.8

2.进入工作目录，准备配置环境

mkdir ES --创建es目录
cd ES --进入es目录
mkdir config data/data0 data/data1 data/data2 --创建配置目录和数据目录
cd config --进入配置目录
touch es0.yml --创建es配置文件
touch es1.yml
touch es2.yml

es0.yml 文件内容：

cluster.name: elasticsearch-cluster
node.name: es-node0
network.bind_host: 0.0.0.0
network.publish_host: 172.16.128.106
http.port: 9200
transport.tcp.port: 9300
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true 
node.data: true  
discovery.zen.ping.unicast.hosts: ["172.16.128.106:9300","172.16.128.106:9301","172.16.128.106:9302"]
discovery.zen.minimum_master_nodes: 2

es1.yml 文件内容：

cluster.name: elasticsearch-cluster
node.name: es-node1
network.bind_host: 0.0.0.0
network.publish_host: 172.16.128.106
http.port: 9201
transport.tcp.port: 9301
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true 
node.data: true  
discovery.zen.ping.unicast.hosts: ["172.16.128.106:9300","172.16.128.106:9301","172.16.128.106:9302"]
discovery.zen.minimum_master_nodes: 2

es2.yml 文件内容：

cluster.name: elasticsearch-cluster
node.name: es-node2
network.bind_host: 0.0.0.0
network.publish_host: 172.16.128.106
http.port: 9202
transport.tcp.port: 9302
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true 
node.data: true  
discovery.zen.ping.unicast.hosts: ["172.16.128.106:9300","172.16.128.106:9301","172.16.128.106:9302"]
discovery.zen.minimum_master_nodes: 2

注意 172.16.128.106 是我的ip，这里要替换成主机的局域网ip

3.启动集群

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9200:9200 -p 9300:9300 -v ~/docker/es5/config/es0.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v ~/docker/es5/data/data0:/usr/share/elasticsearch/data --name ES00 elasticsearch:5.6.8

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9201:9201 -p 9301:9301 -v ~/docker/es5/config/es1.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v ~/docker/es5/data/data1:/usr/share/elasticsearch/data --name ES01 elasticsearch:5.6.8

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9202:9202 -p 9302:9302 -v ~/docker/es5/config/es2.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v ~/docker/es5/data/data2:/usr/share/elasticsearch/data --name ES02 elasticsearch:5.6.8

启动完成以后就可以通过chrome浏览器插件访问看效果了：

以上就是简单的搭建流程，有问题欢迎留言探讨～
