Fix with ulimit -n 8192

Question

Running caddy on a linux machine, and I receive the following error:

WARNING: File descriptor limit 1024 is too low for production servers.
         At least 8192 is recommended. 

         Fix with "ulimit -n 8192"

Ok, great. But where do I fix it?

@RehanAzher, if you have an answer, put it as an answer rather than a series of context-free comments. Also I'm sure the OP wants something permanent; clearly they know the command that needs to be run already. — Jim Stewart, Apr 03 '18 at 14:31

For a temporary fix, you can simply issue the command ulimit -n 8192.

For permanent you need to modify /etc/security/limits.conf.

For more details please refer below:

From article:

vi /etc/security/limits.conf

Add two lines for each limit:

* soft nofile 16384
* hard nofile 16384

And I recommend raising the NOFILES limit (ulimit -n) as high as you can, if your web server is the only primary purpose of the machine; you might as well, to make sure traffic spikes don't take you down. – Matt Apr 03 '18 at 15:28
