Enviroment:  
VirtualBox three servers with Ubuntu 18.04 LTS and network bridge.  
`Master: 106`  
`ES01: 107`  
`ES02: 108`

ElasticSearch Version 7.6.1

This is my configuration `elasticsearch.yml` file:  
MASTER:

```auto
cluster.name: my-app
node.name: master
node.data: true
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
bootstrap.memory_lock: true
network.host: ["127.0.0.1","192.168.1.106"]
discovery.zen.ping.unicast.hosts: ["192.168.1.107","192.168.1.108"]
discovery.zen.minimum_master_nodes: 2

```

ES01

```auto
cluster.name: my-app
node.name: es01
node.data: true
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
bootstrap.memory_lock: true
network.host: ["127.0.0.1","192.168.1.107"]
discovery.zen.ping.unicast.hosts: ["192.168.1.106","192.168.1.108"]
discovery.zen.minimum_master_nodes: 2

```

ES02

```auto
cluster.name: my-app
node.name: es02
node.data: true
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
bootstrap.memory_lock: true
network.host: ["127.0.0.1","192.168.1.108"]
discovery.zen.ping.unicast.hosts: ["192.168.1.106","192.168.1.107"]
discovery.zen.minimum_master_nodes: 2

```

File: `/etc/default/elasticsearch` uncomment `MAX_LOCKED_MEMORY=unlimited`  
File: `/etc/default/elasticsearch` Add Line `LimitMEMLOCK=infinity`  
Then reload daemon with command `systemctl daemon-reload`  
And when I go to:  
`http://192.168.1.106:9200/_cluster/health`  
This return `"number_of_nodes": 1` on each node

Nevermind I already fixed it. Just wipe all nodes.
