我已经安装了 elasticsearch 2.2.3 并在 2 个节点的集群中配置
节点 1 (elasticsearch.yml)
cluster.name: my-cluster
node.name: node1
bootstrap.mlockall: true
discovery.zen.ping.unicast.hosts: ["ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com", "ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com"]
discovery.zen.minimum_master_nodes: 1
discovery.zen.ping.multicast.enabled: false
indices.fielddata.cache.size: "30%"
indices.cache.filter.size: "30%"
node.master: true
node.data: true
http.cors.enabled: true
script.inline: false
script.indexed: false
network.bind_host: 0.0.0.0
节点 2 (elasticsearch.yml)
cluster.name: my-cluster
node.name: node2
bootstrap.mlockall: true
discovery.zen.ping.unicast.hosts: ["ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com", "ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com"]
discovery.zen.minimum_master_nodes: 1
discovery.zen.ping.multicast.enabled: false
indices.fielddata.cache.size: "30%"
indices.cache.filter.size: "30%"
node.master: false
node.data: true
http.cors.enabled: true
script.inline: false
script.indexed: false
network.bind_host: 0.0.0.0
如果我得到 curl -XGET 'http://localhost:9200/_cluster/state?pretty' 我有:
{
"error" : {
"root_cause" : [ {
"type" : "master_not_discovered_exception",
"reason" : null
} ],
"type" : "master_not_discovered_exception",
"reason" : null
},
"status" : 503
}
进入节点1的日志有:
[2016-06-22 13:33:56,167][INFO ][cluster.service ] [node1] new_master {node1}{Vwj4gI3STr6saeTxKkSqEw}{127.0.0.1}{127.0.0.1:9300}{master=true}, reason: zen-disco-join(elected_as_master, [0] joins received)
[2016-06-22 13:33:56,210][INFO ][http ] [node1] publish_address {127.0.0.1:9200}, bound_addresses {[::]:9200}
[2016-06-22 13:33:56,210][INFO ][node ] [node1] started
[2016-06-22 13:33:56,221][INFO ][gateway ] [-node1] recovered [0] indices into cluster_state
改为进入节点 2 的日志:
[2016-06-22 13:34:38,419][INFO ][discovery.zen ] [node2] failed to send join request to master [{node1}{Vwj4gI3STr6saeTxKkSqEw}{127.0.0.1}{127.0.0.1:9300}{master=true}], reason [RemoteTransportException[[node2][127.0.0.1:9300][internal:discovery/zen/join]]; nested: IllegalStateException[Node [{node2}{_YUbBNx9RUuw854PKFe1CA}{127.0.0.1}{127.0.0.1:9300}{master=false}] not master for join request]; ]
哪里出错了？
最佳答案
我用这一行解决了:
network.publish_host: ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com
每个 elasticsearch.yml 配置文件都必须包含您的主机名这一行
