I have created mongodb database server in linode dedicated host and while tuning the database server for optimal permormence i could not increase the value of ulimit -n I have asked chat GPT, and search alot of forum and google for help no none of them work for me.
Also i want to know what else i have to do to optimize the permormence of my server (one main server and one replica set are configured each having 2 core cpu 20 GB Storage and 24 GB RAM)
i haved tried following configuration:
file name: /etc/security/limits.conf
* soft nofile 64000
* hard nofile 64000
file name:/etc/sysctl.conf
fs.file-max = 64000
file name: /etc/systemd/system.conf
DefaultLimitNOFILE=64000
and restart my server still i got the following output
root@host:# sysctl fs.file-max
fs.file-max = 64000
root@host:# cat /etc/security/limits.conf
* soft nofile 64000
* hard nofile 64000
root@host:# ulimit -n
1024
the only command works is
ulimit -n 64000 but once i logout and login again the ulimit reset back to 1024.
