java - elasticsearch 进程的最大文件描述符太低

Question

无法解决这些问题:

[2017-10-16T13:54:23,381][WARN ][o.e.b.BootstrapChecks    ] [node-1] max 
file descriptors [65000] for elasticsearch process is too low, increase to 
at least [65536]
[2017-10-16T13:54:23,382][WARN ][o.e.b.BootstrapChecks    ] [node-1] max 
number of threads [1024] for user [appadm01] is too low, increase to at 
least [2048]
[2017-10-16T13:54:23,382][WARN ][o.e.b.BootstrapChecks    ] [node-1] system 
call filters failed to install; check the logs and fix your configuration or 
disable system call filters at your own risk

我执行了 sysctl -w fs.file-max=65536 但我得到了同样的结果。

Answer 1

对于使用 docker 运行 Elasticsearch 的用户，您可以通过如下所示的 docker run 命令设置 ulimit。

docker run --ulimit nofile=65536:65536 -p 9200:9200 --name elastic-search docker.elastic.co/elasticsearch/elasticsearch:6.4.2

希望这对 docker 用户有帮助
