Hi, I'm trying to setup a 3 nodes cluster. My configuration is : ``` cluster.name: dxproelsme node.name: dxproelsme01 path.data: /var/lib/elasticsearch path.logs: /var/log/elasticsearch network.host: _site_ discovery.seed_hosts: - 172.22.2.81 - 172.22.2.82 - 172.22.2.83 cluster.initial_master_nodes: - 172.22.2.81 - 172.22.2.82 - 172.22.2.83 node.master: true node.data: true xpack.security.enabled: false ``` No erros in logs. Only one node in cluster on each node. curl [http://172.22.2.81:9200/\_cluster/health?pretty](http://172.22.2.81:9200/_cluster/health?pretty) ``` { "cluster_name" : "dxproelsme", "status" : "green", "time_out" : false, "number_of_nodes" : 1, "number_of_data_nodes": 1, "active_primary_shards" : 0, "active_shards": 0 , .... } ``` Thanks for your help. ---

network.host: "_site_" might not bind to the correct network if you have multiple network interface. You should be the specific network interface or IP address Eg. If all your network interface, you want to bind "_eth0_" or simply just hardcode the IP address "172.22.2.81" ---

I have only one IP address. I also try with IP address but i have the same behaviour. I see the good IP address in logs. ---

Try this? network.host will be different for each host Also see /var/log/messages for any additional error logs ```auto cluster.name: dxproelsme node.name: dxproelsme01 path.data: /var/lib/elasticsearch path.logs: /var/log/elasticsearch network.host: 172.22.2.81 discovery.seed_hosts: - 172.22.2.81 - 172.22.2.82 - 172.22.2.83 cluster.initial_master_nodes: - dxproelsme01 - dxproelsme02 - dxproelsme03 ``` ---

Can you share the full output of `GET /` from all three nodes? I.e. something like these three commands: ```nohighlight curl http://172.22.2.81:9200/ curl http://172.22.2.82:9200/ curl http://172.22.2.83:9200/ ``` ---

**Author:** ![DavidTurner](https://sea2.discourse-cdn.com/elastic/user_avatar/discuss.elastic.co/davidturner/32/22453_2.png) [@DavidTurner](https://discuss.elastic.co/u/DavidTurner)\ **Post date:** [May 31, 2019, 11:35am UTC](https://discuss.elastic.co/t/solved-dont-succeed-to-create-cluster-es-7-1/183690/10 "2019-05-31T11:35:34Z")
Thanks. The three nodes all have distinct cluster UUIDs: ```nohighlight "cluster_uuid" : "Ki2hYWPYTH-XL3Fm6sIKxg", "cluster_uuid" : "6CCZsxyYSJylB9P_kujFlA", "cluster_uuid" : "sRZoKEEDQZywbRU3qb8L0Q", ``` This is probably because the first time they started up you were not using the config you quote above, and so they each formed a one-node cluster. You cannot merge separate clusters together. Instead you will need to start again from the beginning: wipe their data directories and restart them, and they should form into a single cluster this time. ---

Someone start all node before the configuration. I delete data dir and now it's ok. Thanks. ---
