### Enable this to use rrdcached. Be sure rrd_dir is within the rrdcached dir

Final…
I also cant setting librenms as vhost. At my server i have phpipam and cacti.I set *:81 for phpipam and cacti,
disable all change in .env config.php and .htaccess for librenms and finally i get back webface with all graphs etc.
When i try to set *:80 in cacti or phpipam for apache settings i lose librenms and any setting for librenms vhost like changing in .env .htaccess and config.php(like here https://docs.librenms.org/Extensions/Sub-Directory/ doesn’t help to phpipam and cacti using 80 port.
So i’m still need help to setting librenms as vhost wich will work with other system on 80 port.
Now at 80 port work only librenms, if i change 81 to 80 port for cacti and phpipam(in apache conf files) i broke librenms.
Help,please
