Thread:Project:Support desk/How can I set up multi-wiki by one Mediawiki source code?

Fore example I want to set up 3 wikis. en.moywiki.org zh.moywiki.org ja.moywiki.org Can I install the wiki source code in home/wiki/. Then put separate config in different directory. Different wiki will use different database but same source code.

Will this be possible?

Now I can let en.moywiki.org direct to /home/en, but I can't make it work.
