ElasticSearch 5.0.0-aplha4将不会启动而不设置vm.max_map_count

问题描述

我希望将我的ES版本从2.3更新为5.0.0-alpha4，以便能够使用Ingest节点并将Logstash从问题中删除。但似乎ES 5.x版本不会启动没有我将vm.max_map_count设置为262144.我不想设置该值。我可以默认值65530.任何人都可以指导我如何获得ES 5。 x开始没有篡改内存设置。我无法访问我希望安装ES的主机上的root用户。

解决方案

从ES 5开始，有一些（仅在Linux上），这需要262144内存 - 映射区域或者它将拒绝启动。

请注意，无论环境ES运行（dev或prod），此检查都将被执行

I wish to update my ES version from 2.3 to 5.0.0-alpha4 to be able to use Ingest nodes and remove Logstash out of the question. But it seems ES 5.x version won't start without me setting vm.max_map_count to 262144. I don't want to set that value..I am okay with default value 65530. Can anyone guide me how to get ES 5.x started without tampering memory settings at all. I don't have access to root user on the host on which i wish to install ES.

解决方案

Starting with ES 5, there are some bootstrap checks that are enforced.

One of those checks is the Maximum map count check (on Linux only), which requires 262144 memory-mapped areas or it will refuse to start.

Note that this check is enforced whatever the environment ES runs in (dev or prod)
