Thanks. I am using Linux Redhat and I can not find the file. How should
I deal with it?

Just create it in your home dir:

echo “IRB.conf[:SAVE_HISTORY] = 1000” > ~/.irbrc

.irbrc is loaded every time you start irb. It’s a plain ruby code, you
can put there anything you need for your irb session. Try searching on
the web for some examples how other people make use of .irbrc file, you
will certainly find interesting use cases.
