Hello and thanks for choosing KeyHelp!
1. How can I use domain alias (not mail alias)?
Let's say you have a domain "domain.com" pointing to a directory "/www/wordpress/" and a second domain "alias.com". Now, go to the edit page of "alias.com" and let it point to the same folder as "domain.com". (Technically it is not the 'Alias' directive which you would may set, when writing a vhost config for Apache, but the result is the same.)
Additional note: From SEO perspective this is maybe not the thing you want, because Google may punish such websites, called 'duplicate content' - you may want to setup a 301 redirect from "alias.com" to "domain.com" - just go to the edit page of "alias.com" and write into the 'Target' input field "
http://domain.com" and choose the 301 redirect.
2. How can I configure log rotation every 30 days and disable anonymization?
Currently there is no way to configure logrotate settings via KeyHelp GUI, however you can edit KeyHelps logrotate config file manually. It is located here:
You can disable IP Anonymization on Settings -> Server Settings -> Log settings.
There you find 2 config options to setup the feature in the way you need.
P.s. possible translation error, or I do not understand something?
You are right, this is a translation error in the current version, the correct sentence would be:
"If this option is disabled, the analyzing and parsing of web server log files by the analyzing tool AWStats is disabled."
