i want to increase the open file descriptor size in linux current size is
ulimit -n
returns 1024
i want to increase it to 65535 because my elasticsearch process needs it
here is the link i am following
https://www.elastic.co/guide/en/elasticsearch/reference/current/setting-system-settings.html#limits.conf
i did added following line in /etc/security/limits.conf
* soft nofile 1024
* hard nofile 65535
root soft nofile 1024
root hard nofile 65535
rebooted the system and ulimit -n still returning 1024
another solution i added these lines in /etc/security/limits.conf
* soft nofile 64000
* hard nofile 64000
* - nproc 16384
root - nproc 16384
root soft nofile 64000
root hard nofile 64000
and
/etc/pam.d/common-session needs to have this line in it:
session required pam_limits.so
and added following line in /etc/pam.d/common-session-noninteractive :
session required pam_limits.so
rebooted the system and it did not worked either followed this link as well https://docs.oracle.com/cd/E19623-01/820-6168/file-descriptor-requirements.html it gives error on the last command
ulimit -n unlimited
bash: ulimit: open files: cannot modify limit: Operation not permitted
and
sudo ulimit -n unlimited
sudo: ulimit: command not found
my elasticsearch process is giving me this error
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]
any help would be appreciated
