Hi everyone, I want to set up a cluster on my Centos7. and this is my elasticsearch.yml. ``` ---------------------------------- Cluster ----------------------------------- Use a descriptive name for your cluster: cluster.name: Winoc logger ------------------------------------ Node ------------------------------------ Use a descriptive name for the node: node.name: Centos1 Add custom attributes to the node: #node.attr.rack: r1 ---------------------------------- Network ----------------------------------- Set the bind address to a specific IP (IPv4 or IPv6): network.host: 192.168.0.120 transport.host: localhost Set a custom port for HTTP: #http.port: 9200 For more information, consult the network module documentation. ----------------------------------- Paths ------------------------------------ Path to directory where to store the data (separate multiple locations by comma): #path.data: /path/to/data Path to log files: #path.logs: /path/to/logs #discovery.zen.minimum_master_nodes: For more information, consult the zen discovery module documentation. ---------------------------------- Gateway ----------------------------------- Block initial recovery after a full cluster restart until N nodes are started: #gateway.recover_after_nodes: 3 For more information, consult the gateway module documentation. ---------------------------------- Various ----------------------------------- Require explicit names when deleting indices: #action.destructive_requires_name: true # --------------------------------- Discovery ---------------------------------- # # Pass an initial list of hosts to perform discovery when new node is started: # The default list of hosts is ["127.0.0.1", "[::1]"] # discovery.zen.ping.unicast.hosts: ["192.168.0.120", "192.168.0.243"] # # Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1): # #discovery.zen.minimum_master_nodes: # # For more information, consult the zen discovery module documentation. # # Block initial recovery after a full cluster restart until N nodes are started: # #gateway.recover_after_nodes: 3 # # For more information, consult the gateway module documentation. # ``` log: > **[來個 PPT 短網址 :: 縮圖剪剪樂!](https://ppt.cc/fVsg1x)** > > PPT 短網址，縮圖剪剪樂! another node of elasticsearch.yml has the same cluster name. but the node can't find each other. thank you in advance! ---

Please edit your post and use the code button - `` - to format things. Alternatively, use the markdown style backticks. It's really hard to read your config as is, which makes it hard to help. Also, please post logs. ---

I think the cluster name is weird. I'm unsure you can have "Spaces" in its name `cluster.name: Winoc logger`. I'd try to change that probably. `transport.host: localhost` means that only local nodes will be able to connect to this node. So You can't form a cluster. ---

oh, but if I comment out transport.host: localhost and the Elasticsearch can't run any more. > **[來個 PPT 短網址 :: 縮圖剪剪樂!](https://ppt.cc/fpuJSx)** > > PPT 短網址，縮圖剪剪樂! ---

sorry for that. if I comment out transport.host: localhost. There are some problems ``` [2018-01-15T17:41:58,387][INFO][o.e.n.Node] [Centos1] starting ...

so weird, another node log: ``` 2018-01-15T05:20:05,020][INFO][o.e.d.z.ZenDiscovery] [Centos3] failed to send join request to master [{Centos2}{xRZYgk5bR1WTCdwd4rX3TA}{072YqViAQg6c6B8EJAH-pw}{192.168.0.243}{192.168.0.243:9300}], reason [RemoteTransportException[[Centos2][192.168.0.243:9300][internal:discovery/zen/join]]; nested: ConnectTransportException[[Centos3][127.0.0.1:9300] connect_exception]; nested: IOException[Connection refused: 127.0.0.1/127.0.0.1:9300]; nested: IOException[Connection refused]; ] [2018-01-15T05:20:08,025][INFO][o.e.d.z.ZenDiscovery] [Centos3] failed to send join request to master [{Centos2}{xRZYgk5bR1WTCdwd4rX3TA}{072YqViAQg6c6B8EJAH-pw}{192.168.0.243}{192.168.0.243:9300}], reason [RemoteTransportException[[Centos2][192.168.0.243:9300][internal:discovery/zen/join]]; nested: ConnectTransportException[[Centos3][127.0.0.1:9300] connect_exception]; nested: IOException[Connection refused: 127.0.0.1/127.0.0.1:9300]; nested: IOException[Connection refused]; ] ``` I think the problem is transport.host: localhost , but if I comment out it, and it can't run. ---
