Change limits (ulimit) to RHEL root user?

Question

linux

Hello everyone, I experimented with setting limits in /security/limits.conf, set the nofile -1 parameter to the root user, now I can’t log in :), there are other users on the server, but they are not sudo, Dear community, tell me how to change the user, using the su - root command, is it possible to set the limits correctly (Perhaps using setrlimit)? Well, or tell me options how this parameter can be returned / changed. Thank you!

Answer 1

Never experiment with root
Open the server console.
Reboot.
Enter single (or emergency) mode.
Mount filesystems (or at least / remount to rw)
Fix limits.conf
Reboot.
And never experiment with root again

Answer 2

One of the two
1) reboot into single user mode, and fix it
2) boot from resque disk, mount the system disk, and fix it
