1.集群配置 需要修改
cluster.name 、node.name 、network.host: 0.0.0.0【此處默認localhost】、http.port: 9200
只要集群名相同，且機器處於同一局域網同一網段，es會自動去發現其他的節點
注意：elasticsearch.yml中設置項中冒號右邊要加一個空格
2.提示錯誤
問題一：警告提示 [2016-12-20T22:37:28,543][INFO ][o.e.b.BootstrapCheck ] [elk-node1] bound or publishing to a non-loopback or non-link-local address, enforcing bootstrap checks [2016-12-20T22:37:28,552][ERROR][o.e.b.Bootstrap ] [elk-node1] node validation exception bootstrap checks failed max number of threads [1024] for user [elasticsearch] is too low, increase to at least [2048] [2016-12-20T22:37:28,560][INFO ][o.e.n.Node ] [elk-node1] stopping ... [2016-12-20T22:37:28,628][INFO ][o.e.n.Node ] [elk-node1] stopped [2016-12-20T22:37:28,629][INFO ][o.e.n.Node ] [elk-node1] closing ... [2016-12-20T22:37:28,677][INFO ][o.e.n.Node ] [elk-node1] closed 報了一大串錯誤，其實只是一個警告。 解決：使用心得linux版本，就不會出現此類問題了。 問題二：ERROR: bootstrap checks failed max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536] max number of threads [1024] for user [lishang] likely too low, increase to at least [2048] 解決：切換到root用戶，編輯limits.conf 添加類似如下內容 vi /etc/security/limits.conf 添加如下內容: * soft nofile 65536 * hard nofile 131072 * soft nproc 2048 * hard nproc 4096 問題三：max number of threads [1024] for user [lish] likely too low, increase to at least [2048] 解決：切換到root用戶，進入limits.d目錄下修改配置文件。 vi /etc/security/limits.d/90-nproc.conf 修改如下內容： * soft nproc 1024 #修改為 * soft nproc 2048 問題四：max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144] 解決：切換到root用戶修改配置sysctl.conf vi /etc/sysctl.conf 添加下面配置： vm.max_map_count=655360 並執行命令： sysctl -p 然后，重新啟動elasticsearch，即可啟動成功。
