The Elasticsearch documentation says that I should configure nofile and nproc for better performance.
But the documentation is a bit confusing.
First, do I set it to the "elastic" user that was created by Elasticsearch upon installation or to the "elasticsearch" user (which was not created at all)?
Second, how will the file
/etc/security/limits.conf actually look after configuration? Will it look like the code below?
elasticsearch - nofile 65535
elasticsearch - nproc 4096
How did you install elasticsearch? If you installed using a package manager like
rpm than the user
elasticsearch will be created during installation.
You need to edit the limits for the user that will run Elasticsearch, which is normally
Also, if you installed using
rpm you basically do not need to worry about
nproc as the systemd process will set it automatically.
But if you need to manually configure the file this is correct:
Thanks @leandrojmp ,
I installed using Debian Package.
However, should I still worry about changing the
sysctl -w vm.max_map_count=262144 and
You need to add the
LimitMEMLOCK to a systemd override file, but does not need to configure the
vm.max_map_count when using systemd.
You need to follow the documentation about Important System Configuration and do what it is need to your case.
When using packages like DEB or RPM, there is not much to change.
