弹搜索错误--在during过程中发现的主节点不足

Question

 # ======================== Elasticsearch Configuration ========================= 
#cluster.name: my-application 
node.name: node-1 
node.master: true 
node.data: true  
network.host: 172.31.24.193 
discovery.zen.ping.unicast.hosts:["172.31.24.193","172.31.25.87","172.31.23.237"]

节点-2 elasticsearch.yml配置

  # ======================== Elasticsearch Configuration ========================= 
#cluster.name: my-application 
node.name: node-2 
node.master: true 
node.data: true  
network.host: 172.31.25.87 
discovery.zen.ping.unicast.hosts:["172.31.24.193","172.31.25.87","172.31.23.237"] 

节点-3弹性搜索配置

  # ======================== Elasticsearch Configuration ========================= 
#cluster.name: my-application 
node.name: node-3 
node.master: true 
node.data: true  
network.host: 172.31.23.237 
discovery.zen.ping.unicast.hosts:["172.31.24.193","172.31.25.87","172.31.23.237"] 

错误描述：我安装了一个ec2-discovery插件。我在弹性密钥库中传递AWS访问密钥和秘密密钥和端点。

我使用的是最新的弹性搜索6.2。我已经启动了亚马逊ec2实例上的所有节点。我有三个ec2实例。我在这三个节点上都得到了这样的错误

[node-2] not enough master nodes discovered during pinging (found [[Candidate{node={node-2}{TpI8T4GBShK8CN7c2ruAXw}{DAsuqCnISsuiw6BGvqrysA}{172.31.25.87}{172.31.25.87:9300}, clusterStateVersion=-1}]], but needed [2]), pinging again

Answer 1

首先，要使用EC2-发现，您需要在您的elasticsearch.yml：discovery.zen.hosts_provider: ec2中使用它并删除discovery.zen.ping.unicast.hosts。

请检查https://www.elastic.co/guide/en/elasticsearch/plugins/current/discovery-ec2-usage.html

EC2-发现的思想不是硬编码配置文件中的节点in，而是自动“发现”它们。

第二，您提供的错误表明，节点无法相互平分，请确保在您的安全组中设置了允许此操作的规则。在InBound选项卡中，添加一个新规则：

类型:所有TCP

来源:您的安全组id (sg-xxxxxx)
