Hello.

I was installing zimbra for the first time, and noticed that the domain on the hostname was wrong. Aborted instalation, changed hostname in /etc/sysconfig/network (i'm in CentOS) and didn't had nothing in /etc/hosts.
Rebooted.

When i try to install, i get this error:
Code:
Press Return to continue


        ERROR: Installation can not proceeed.  Please fix your /etc/hosts file
        to contain:

        127.0.0.1 localhost.localdomain localhost

        Zimbra install grants mysql permissions only to localhost and
        localhost.localdomain users.  But Fedora/RH installs leave lines such
        as these in /etc/hosts:

        127.0.0.1     myhost.mydomain.com myhost localhost.localdomain localhost

        This causes MySQL to reject users coming from 127.0.0.1 as users from
        myhost.mydomain.com.  You can read more details at:

        http://bugs.mysql.com/bug.php?id=11822
That's ok, but if i do this, the instalation will configure all servers with this domain, (localhost.localdomain) and the servers wont start.

if i leave it empty, i've got an java error:
Code:

Tryed to install dozens of times, erased all files from zimbra install...


Is there an uninstall?
Is there a way to solve this?

Thanks in advance.
