Elasticsearch 5.0.1 Java-Berechtigungsproblem

Question

Ich habe versucht, Elasticsearch 5.0.1 in einem docker container basierend auf Centos 6.8 zu installieren und auszuführen. Ich erhalte folgenden Fehler:

Kann mir bitte jemand helfen, diesen Fehler zu verstehen und zu beheben?

Answer 1

So nach dem Fehler, haben Sie die vm.max_map_count plus die max number of threads zu erhöhen.

Um vm.max_map_count Typ im folgenden Befehl in das Terminal als root zu erhöhen:

sysctl -w vm.max_map_count=262144

Quelle: configuration

Um die max number of threads zu erhöhen, Sie haben die ulimit zu erhöhen:

This can be done by setting ulimit -u 2048 as root before starting Elasticsearch, or by setting nproc to 2048 in /etc/security/limits.conf.
