通过docker配置基于 elastic search的两个node的集群，熟悉elastic search配置和了解shards replicas。

docker环境

通过docker可以快速在一个host上面，搭建多节点cluster 环境。创建如下两个节点

docker pull elasticsearch

docker run -d --name es-node2 -p 9200:9200 -v ~/docker/es-node2:/home/alex  elasticsearch

docker run -d --name es-node3 --link es-node2 -v ~/docker/es-node3:/home/alex elasticsearch

es-node2作为主node，es-node3作为从node

➜  ~  docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                              NAMES  
fa8816f65854        elasticsearch       "/docker-entrypoint.s"   34 minutes ago      Up 3 seconds        9200/tcp, 9300/tcp                 es-node3  
44a8cfc9fce1        elasticsearch       "/docker-entrypoint.s"   36 minutes ago      Up 5 seconds        0.0.0.0:9200->9200/tcp, 9300/tcp   es-node2

配置elasticsearch.yml

进去Mac主机的映射目录,配置elasticsearch.yml

➜  ~  cd es-node2 
➜  ~  cat elasticsearch.yml 

加入
cluster.name: "cluster"  
node.name: node-2  
node.master: true  
node.data: true  
network.host: 0.0.0.0  
discovery.zen.ping.multicast.enabled: false  
discovery.zen.ping.unicast.hosts: ["172.17.0.2", "172.17.0.3"]  
discovery.zen.minimum_master_nodes: 1  
discovery.zen.ping.timeout: 3s

➜  ~  cd es-node3
➜  ~  cat elasticsearch.yml 

加入
cluster.name: "cluster"  
node.name: node-3  
node.master: true  
node.data: true  
network.host: 0.0.0.0  
discovery.zen.ping.multicast.enabled: false  
discovery.zen.ping.unicast.hosts: ["172.17.0.2", "172.17.0.3"]  
discovery.zen.minimum_master_nodes: 1  
discovery.zen.ping.timeout: 3s

拷贝配置文件:

进入es-node2
➜  ~  bash -c "clear && DOCKER_HOST=tcp://192.168.99.100:2376 DOCKER_CERT_PATH=/Users/alex/.docker/machine/machines/default DOCKER_TLS_VERIFY=1 docker exec -it es-node2 sh"

# cp /home/alex/elasticsearch.yml /usr/share/elasticsearch/config

进入es-node3
➜  ~  bash -c "clear && DOCKER_HOST=tcp://192.168.99.100:2376 DOCKER_CERT_PATH=/Users/alex/.docker/machine/machines/default DOCKER_TLS_VERIFY=1 docker exec -it es-node3 sh"

# cp /home/alex/elasticsearch.yml /usr/share/elasticsearch/config

重启服务:

➜  ~  docker ps     
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                              NAMES  
e964e232c2d1        elasticsearch       "/docker-entrypoint.s"   54 minutes ago      Up 6 minutes        9200/tcp, 9300/tcp                 es-node3  
18b936f6b729        elasticsearch       "/docker-entrypoint.s"   54 minutes ago      Up 6 minutes        0.0.0.0:9200->9200/tcp, 9300/tcp   es-node2

分别重启container
➜  ~  docker restart 18b936f6b729
➜  ~  docker restart e964e232c2d1

访问测试页面

http://192.168.99.100:9200/_cluster/health?pretty

可以看到如下信息: 两个node，作为data_nodes

  "number_of_nodes" : 2,
  "number_of_data_nodes" : 2,

安装插件

进入两个node，通过如下命令安装kopf插件,

root@44a8cfc9fce1:/# /usr/share/elasticsearch/bin/plugin install lmenezes/elasticsearch-kopf/v2.0.1

未完...
