elk 添加节点:

cluster.name: es_cluster

node.name: node03

path.data: /elk/elasticsearch/data

path.logs: /elk/elasticsearch/logs

network.host: 192.168.32.82

network.port: 9200

zjtest7-haproxy:/usr/local/elasticsearch-2.3.4/config# mkdir -p /elk/elasticsearch/data

zjtest7-haproxy:/usr/local/elasticsearch-2.3.4/config# mkdir -p  /elk/elasticsearch/logs

zjtest7-haproxy:/usr/local/elasticsearch-2.3.4/config# groupadd elk

zjtest7-haproxy:/usr/local/elasticsearch-2.3.4/config# useradd -m -g elk elk

zjtest7-haproxy:/usr/local/elasticsearch-2.3.4/config# passwd elk

zjtest7-haproxy:/usr/local/elasticsearch-2.3.4/config# chown -R elk:elk /usr/local/elasticsearch-2.3.4

zjtest7-haproxy:/usr/local/elasticsearch-2.3.4/config# chown -R elk:elk /elk

3 4 . 设置新节点被启动时能够发现的主节点列表（主要用于不同网段机器连接）： 

discovery.zen.ping.unicast.hosts: ["host1", "host2:port", "host3[portX-portY]"]

# action.destructive_requires_name: true

cluster.name: es_cluster

node.name: node03

path.data: /elk/elasticsearch/data

path.logs: /elk/elasticsearch/logs

network.host: 192.168.32.82

network.port: 9200

discovery.zen.ping.unicast.hosts: ["192.168.32.80", "192.168.32.81","192.168.32.82"]

需要加上主节点,所有节点通过主节点通信的
