本文详细介绍了如何从零开始部署一个Elasticsearch集群，包括创建挂载目录、设置权限、配置节点参数以及通过Docker启动集群的全过程。同时，记录了解决集群启动时遇到的关于虚拟内存区域限制问题的方法。

1、搭建

mkdir -p /data/es/data1
mkdir -p /data/es/data2
mkdir -p /data/es/data3
chmod -R 777 /data/es/data1
chmod -R 777 /data/es/data2
chmod -R 777 /data/es/data3

创建es配置文件

mkdir -p /data/es/config

#vim /data/es/config/es1.yml

cluster.name: elasticsearch-cluster
node.name: es-node1
network.bind_host: 0.0.0.0
network.publish_host: *.*.*.*
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: ["*.*.*.*:9300","*.*.*.*:9301","*.*.*.*:9302"]
discovery.zen.minimum_master_nodes: 2

PS:network.publish_host: *.*.*.*替换为宿主机IP

#vim /data/es/config/es2.yml

cluster.name: elasticsearch-cluster
node.name: es-node2
network.bind_host: 0.0.0.0
network.publish_host: *.*.*.*
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: ["*.*.*.*:9300","*.*.*.*:9301","*.*.*.*:9302"]
discovery.zen.minimum_master_nodes: 2

#vim /data/es/config/es3.yml

cluster.name: elasticsearch-cluster
node.name: es-node3
network.bind_host: 0.0.0.0
network.publish_host: *.*.*.*
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: ["*.*.*.*:9300","*.*.*.*:9301","*.*.*.*:9302"]
discovery.zen.minimum_master_nodes: 2

启动es集群

 docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9200:9200 -p 9300:9300 -v /data/es/config/es1.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /data/es/data1:/usr/share/elasticsearch/data --name ES01 elasticsearch:6.8.5
 
 docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9201:9201 -p 9301:9301 -v /data/es/config/es2.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /data/es/data2:/usr/share/elasticsearch/data --name ES02 elasticsearch:6.8.5

 docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9202:9202 -p 9302:9302 -v /data/es/config/es3.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /data/es/data3:/usr/share/elasticsearch/data --name ES03 elasticsearch:6.8.5

2、问题记录

bootstrap checks failed max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]

vim /etc/sysctl.conf

vm.max_map_count=262144 

sysctl -p
