How can i raise my Centos max open file descriptor limit?

Hello

How can i raise my Centos max open file descriptor limit from 1024 to 65000 ?

Thank you

 

This is off the top of my head, If you have root access and are editing for root:
sysctl -w fs.file-max=2500
and to save it upon reboot add it to /etc/sysctl.conf in this format:
fs.file-max = 2500

Obviously not that low

Hopefully this helps

 

Do i have to run the command and add also on /etc/sysctl.conf the:

fs.file-max = 65000

I must do both?

Do i have to restart anything to start use this setting?

Thank you

 

You can run the command to have it take immediate effect and then add it to the sysctl file to make it 'stick' after reboot. Or just add it to the sysctl and reboot.

 

note, none of this applies to VPS's. Contact your host if that's what you're on.

 

Ok thanks
