To change maximum open file limits for your terminal session, run this command:

# ulimit -n 3000

After closing the terminal and creating a new session, the limits will get back to the original values specified in /etc/security/limits.conf.

To change the general value for the system /proc/sys/fs/file-max, change the fs.file-max value in /etc/sysctl.conf:

fs.file-max = 100000

And apply it:

# sysctl -p
