Upgrade to Plesk 12 said: hostname: Unknown host

[Azurel]

I use "CentOS 6.6 (Final)" with panel version 11.5.30 Update #48 and get this error for upgrade to 12.0:

Parallels Panel pre-upgrade check...
hostname: Unknown host
FATAL_ERROR: Command: hostname -f returns:
Hostname is not defined and configured. Unable to get hostname. Server should have properly configured hostname and it should be resolved locally.

I have in /etc/sysconfig/network:

HOSTNAME="mail"
NETWORKING=yes
NETWORKING_IPV6="yes"
IPV6_DEFAULTDEV="eth0"

I'm a customer from Hosteurope and in HE control panel of server I find:

HOSTNAME = "mail.mydomain.tld"

The same for "Reverse-DNS" in IPv4 and IPv6.

Can anybody tell me what is wrong?

Hello Azurel,
You can set the hostname of your server with:

echo host123.your-domain.com > /etc/hostname
/etc/init.d/hostname.sh start

Thanks, but the file /etc/init.d/hostname.sh not exists on my centOS.
/etc/hostname not exists too. I don't think it should create a new empty file?

It's OK for /etc/init.d/hostname.sh not to exist on CentOS, however /etc/hostname should exist.
Never the less, you can create it and in it add your host name ..

vim /etc/hostname

And add the content such as

host123.your-domain.com

Remember your hostname should resolve to the IP address of that very server.
