View source for Set ulimit without reboot


Modify ''limits.conf'' file located (on most distros) at ''/etc/security/limits.conf''. <br>
Append following lines:
<pre>
* soft     nproc          768000
* hard     nproc          768000
* soft     nofile         768000
* hard     nofile         768000
root soft     nproc          768000
root hard     nproc          768000
root soft     nofile         768000
root hard     nofile         768000
</pre>

This will modify limits for all users to 768000 ( you can modify this number to your needs ) <br>

To apply changes without reboot, modify ''/etc/pam.d/common-session'', by adding this line: <br>
<pre>
session required pam_limits.so
</pre>

Note: You need to relogin in order to see updated limits.
