Elasticsearch 5.2.2在谷歌計算引擎上啓動的問題

Question

ES版本5.2.2和Discovery GCE 5.2.2

我有一個具有內部和外部IP的GCE。我從源代碼安裝了ES 5.2.2，然後安裝了Discovery GCE。我將network.host更改爲'gce'，並將GCE的項目ID，區域等添加到elasticsearch.yml中。

當我嘗試使用'./bin/elasticsearch'啓動實例時，出現以下錯誤。 Bootstrap測試失敗。此外，它還有一條消息：' 無法從網絡接口找到可用的硬件地址;使用隨機字節：d7：0c：ef：bf：d0：7b：a6：95'

任何幫助將不勝感激。

此外，其他一般性問題是不可能在GCE的外部IP上發佈ES？對不起，如果這聽起來太愚蠢，我不是這方面的精明。

你要增加文件描述符按： https://www.elastic.co/guide/en/elasticsearch/reference/current/file-descriptors.html root$ ulimit -n 65536 和最大虛擬MEM： https://www.elastic.co/guide/en/elasticsearch/reference/current/vm-max-map-count.html root$ sysctl vm.max_map_count vm.max_map_count = 262144 root$ sudo sysctl -w vm.max_map_count=262144 或使其永久： 編輯/etc/sysctl.conf，把參數內部 vm.max_map_count = 2621444。

至於「無法從網絡接口找到可用硬件地址」，請確保將api_host設置綁定到非本地主機（127.0.0.1）的傳輸。
