Problem installing zcs 7.1.1

[bysdan]

Hi all, note that i'm new to Linux & to zimbra, so i apologize for my stupid mistakes ahead.

I'm trying to install zcs-7.1.1 on centOS 5.6.
but i keep getting the following error :
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:

MySQL Bugs: #11822: Reverse lookup for 127.0.0.1 not accounted for in mysql_install_db

my hosts file :


# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 prananutrition.com localhost
::1 localhost6.localdomain6 localhost6
91.228.126.111 mail.prananutrition.com mail


and if i change the
127.0.0.1 prananutrition.com localhost
to
127.0.0.1 localhost.localdomain localhost

than i get the following error :


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



Where is the ip address of the host,
is the FULLY QUALIFIED host name, and
is the (optional) hostname-only portion


please help me, what should i do?

You need to have valid DNS A & MX records (if you're behind a NAT router or firewall) and correct /etc/hosts and resolv.conf files, go to the Split DNS article and read how to configure it correctly - you can also check the settings by running all the commands in the 'Verify...' section of that article. This topic has also been covered in many forum posts, if you search the forums you'll find them.

dig mail.prananutritions.com mx

You obviously haven't done what it says in the article, nor have you posted the output of all the commands.

The following command is incorrect:

dig mail.prananutritions.com mx

You are useing the FQDN of your Zimbra server not the domain name, it should be like this:

dig prananutritions.com mx

That is the domain name you should be using.
