Elasticsearch 5.2.2在谷歌計算引擎上啟動時出現問題

Question

ES版本5.2.2和Discovery GCE 5.2.2

我有一個內部和外部IP的GCE。 我從源代碼安裝了ES 5.2.2，然后安裝了Discovery GCE。 我將network.host更改為'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'啟動實例時，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'

任何幫助將非常感激。

另外，其他一般性問題是，不可能在GCE的外部IP上發布ES嗎？ 對不起，如果這聽起來太愚蠢，我在這個領域並不精明。

您必須按以下方式增加文件描述符： https ： //www.elastic.co/guide/en/elasticsearch/reference/current/file-descriptors.html root$ ulimit -n 65536和max virtual 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或者使其永久化：編輯/etc/sysctl.conf，將參數放在vm.max_map_count = 2621444中。

對於“無法從網絡接口找到可用的硬件地址”，請確保將api_host設置綁定到非localhost（127.0.0.1）的傳輸。
