我希望将我的 ES 版本从 2.3 更新到 5.0.0-alpha4，以便能够使用 Ingest 节点并删除 Logstash。但如果我不将 vm.max_map_count 设置为 262144，ES 5.x 版本似乎无法启动。我不想设置该值..我可以使用默认值 65530。任何人都可以指导我如何获取 ES 5。 x 启动时根本没有篡改内存设置。我无权访问我想要安装 ES 的主机上的 root 用户。

从 ES 5 开始，有一些引导检查 https://www.elastic.co/guide/en/elasticsearch/reference/master/bootstrap-checks.html那些被强制执行的。
其中一项检查是最大地图数量检查 https://www.elastic.co/guide/en/elasticsearch/reference/master/_maximum_map_count_check.html（仅限 Linux），需要 262144 个内存映射区域，否则将拒绝启动。
请注意，无论 ES 运行在什么环境（dev 或 prod）中，都会强制执行此检查
