グレイログサーバーがポート12900でバインドされていません
ここでは、何をしても、graylog-serverがポート12900にバインドされない状況があります。 github.com/graylog2/graylog-ansible-roleを使用して、graylog-server-1.1.6-1.noarch、elasticsearch-1.6.2-1.noarch、mongodb-org-server-2.6.10のrpmをインストールしました-1.x86_64、nginx-1.8.0-1.el7.ngx.x86_64（2つのCentOS 7 VM）。グレイログサーバーが起動し、/ var/log/graylog/server.logにエラーを記録しませんが、ポート12900へのバインドに失敗します。

私が使用しているVMには4GBのRAMがあり、JVMは1Gを使用するように構成されています。メモリ不足エラーは次の結果であるかどうか疑問に思います。大量のマルチキャストトランスポートハンドラーを開始します。何かアイデアはありますか？
これを/etc/graylog/server/server.confのelasticsearch_discovery_zen_ping_unicast_hosts値までさかのぼります。これはJavaプロパティファイルであるため、値は次のようにフォーマットする必要があります。
elasticsearch_discovery_zen_ping_unicast_hosts = 10.1.10.134:9300
elasticsearch_discovery_zen_ping_unicast_hosts = 10.1.10.134:9300,10.1.10.133:9300
このようなYAML形式は避けてください。 1.1.6のように、Graylogコードは、不適切にフォーマットされた値にフラグを立てません。
elasticsearch_discovery_zen_ping_unicast_hosts = "10.1.10.134:9300"
elasticsearch_discovery_zen_ping_unicast_hosts = [ "10.1.10.134:9300" ]
