I recently merged apache2 and after doing so, ran the init.d script to start the server, I went to http://127.0.0.1 and got a message saying unkown host. So I tried changing config file options for about an hour and restarting, still the same error. Then I tried to stop apache with the init.d script, and got this

* ERROR: "apache2" has not yet been started.

If I try to stop apache using the apache2ctl program, I get this

httpd (no pid file) not running

I dont know what the problem here is, but I may try to remerge apache2 later on if I cant figure it out.

try out this command:
apache2ctl configtest

Try

/etc/init.d/apache2 zap

Which will reset the init scripts in Gentoo, then try running, look at the logs to see what the problem may of been.
