Elasticsearch多节点集群配置文件
192.168.18.186 安装一个Elasticsearch节点
192.168.18.187 安装两个Elasticsearch节点
主机1安装一个节点的配置文件（192.168.18.186 ）
/usr/local/elasticsearch-1.7.3/config/elasticsearch.yml
cluster.name: elastic-product
node.name: "node18.186"
bootstrap.mlockall: true
network.host: 192.168.18.186
discovery.zen.ping.timeout: 60s
discovery.zen.fd.ping_timeout: 60s
discovery.zen.minimum_master_nodes: 2
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicast.hosts: ["192.168.18.186","192.168.18.187","192.168.18.187:9301"]
index.cache.field.max_size: 50000
index.cache.field.expire: 10m
index.cache.field.type: soft
indices.fielddata.cache.size: 10%
#path.data: /path/to/data
说明：为了防止“脑裂”出现，discovery.zen.minimum_master_nodes参数设置的数字=(集群中节点数/2)+1，如两台或者三台主机则配置，如果只有一个节点，此配置可去掉或配置1。
主机2安装两个节点的配置文件（192.168.18.187）
1、节点一
/usr/local/elasticsearch-1.7.3/config/elasticsearch.yml
cluster.name: elastic-product
node.name: "node18.187"
bootstrap.mlockall: true
network.host: 192.168.18.187
discovery.zen.ping.timeout: 60s
discovery.zen.fd.ping_timeout: 60s
discovery.zen.minimum_master_nodes: 2
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicast.hosts: ["192.168.18.186","192.168.18.187","192.168.18.187:9301"]
index.cache.field.max_size: 50000
index.cache.field.expire: 10m
index.cache.field.type: soft
indices.fielddata.cache.size: 10%
#path.data: /path/to/data
2、节点二
/usr/local/elasticsearch-1.7.3-rep2/config/elasticsearch.yml
cluster.name: elastic-product
node.name: "node18.187-rep2"
bootstrap.mlockall: true
network.host: 192.168.18.187
discovery.zen.ping.timeout: 60s
discovery.zen.fd.ping_timeout: 60s
discovery.zen.minimum_master_nodes: 2
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicast.hosts: ["192.168.18.186","192.168.18.187","192.168.18.187:9301"]
transport.tcp.port: 9301
http.port: 9201
index.cache.field.max_size: 50000
index.cache.field.expire: 10m
index.cache.field.type: soft
indices.fielddata.cache.size: 10%
#path.data: /path/to/data
添加为开机自启方法：
sudo vim /etc/rc.local
/usr/local/elasticsearch-1.7.3-2/bin/elasticsearch -d /usr/local/elasticsearch-1.7.3-2/conf/elasticsearch.yml
