Hi

Instead of blocking webcrawlers and bots which want to index your records (which is generally a good thing) I recommend you implement a sitemap.

* https://koha-community.org/manual/21.11/en/html/cron_jobs.html#sitemap

* https://lists.katipo.co.nz/public/koha/2020-November/055401.html

* https://github.com/Koha-Community/Koha/blob/master/misc/cronjobs/sitemap.pl

Like this the webcrawlers will just access your sitemap instead of every single record in your database. This will decrease memory usage immensely.

Blocking webcrawler by firewall can get very hairy because many bots do not have just one IP address where they come from.

My server memory usage is increasing by some web search engine bots by
access of OPAC. I tried put

*robots.txt in *

on /usr/share/koha/opac/htdocs

As

*User-agent: **

*Disallow: /*

But still, my server is getting loaded by bots. The apache log file shows
bots names like petalbot, Googlebot, AhrefsBot etc. How can I block all
these bots' access to my OPAC pages?
