Ajax login hang under Zimbra 7, CENTOS 6, KVM

[terrylim01]

Hi All,

I am trying to run Zimbra NE 7.1.2 under CENTOS 6.0 64bit.

Installation went well without single error. I created split DNS and modify /etc/hosts file correctly.

The problem is that I could not login web mail Ajax page by domain name.

After typing username and password, It said "Loading" and do nothing.

If I clicked "Switch to the Standard (HTML) version". I could get webmail interface but it is HTML version, not Ajax.

If I accessed webmail login page by IP, To my surprise, I could login webmail page but some functions not working ("Address", "Briefcase"). (If I clicked them, Zimbra did not do anything. )

Admin page is working fine. (https://mydomainname:7071/ )
I could activate my trial license and create account without any problem.

Does anybody have similar problem?

I will be greatly appreciated if someone gives some tip or guidance about this annoying problem.

I am running Zimbra NE 7.1.2 under KVM. KVM host is Ubuntu 11.04 64bit.

Guest OS is CENTOS 6.0 64bit with 3GB RAM and 2 CPU.

Here is some log from zimbra.log

The first point(s), Zimbra NE is not supported on CentOS nor on KVM.

Installation went well without single error. I created split DNS and modify /etc/hosts file correctly.

That would imply a configuration problem, please post the output of all the commands in the 'Verify...' section of the Split DNS article. Can you also confirm if the firewall and SElinux are both disabled?

It is working. Thanks Phoenix.

I followed "verify" section and try to gather information to reply to your post.

I found there was no "search domainname" in /etc/resolve.conf

After I inserted that line, and reboot.

It is working flawlessly.

If I found anything new, I will let you know.

I know CENTOS is not supported by Zimbra officially.

Thanks again.

Glad you've fixed it.

Hi All,

There are more problem after I login.

Couple of menus in Ajax UI are not working, "Tasks and Preference".

It just hang and never show its contents.

I installed Zimbra 7.1.2 with CENTOS 5.6 under the same KVM host two months ago.

I never had any issues regarding CENTOS 5.6 so far.

I simply want to use the latest OS to run Zimbra. I failed.

It could be KVM issue. I do not know.

As Phenix pointed out, it is not supported OS. so, I will give up.

I will use CENTOS 5.6 to run Zimbra for a while.

Thanks for all your help.

I also said that KVM is not a supported platform. Although CentOS is not supported it is a binary compatible rebuild of RHEL and works flawlessly for many users, including me. Since it's first release I've always run Zimbra on CentOS without problems and there should be no reason why you're seeing the problems you're experiencing.

Is your CentSO up to date? Have you disabled the Firewall and SElinux? What's the specification of theis server, specifically how much RAM and how much is allocated to the VM? What else runs on this host?

Thanks for your help and concern, Phoenix.

I forgot to mention that I installed and tested Zimbra 7 + CENTOS 6 in my home KVM box before I installed it into my Datacenter KVM box.

It worked fine. Although I did not test it thoroughly, at least I know I could login and browse menu at my home box.

I verified splitDNS config one more time. There was no difference.

I think it is KVM issue. My local box is running the latest KVM (081011-2ubuntu10) from PPA. My DataCenter is running Ubuntu 11.04 default KVM

As far as I know, that is only difference..

I know I should not write bugs or issues regarding latest KVM in this forum.

So, I had better stopped here.

FYI, I always disabled SELinux and Firewall. I verified by dmesg and iptables -L.

It is minimum installation from CENTOS 6 installer and I installed few more packages like below.

yum install man bind bind-utils openssh-clients perl sysstat nc

I ran visudo to comment out Defaults requiretty

I updated CENTOS 6 by yum update before I installed Zimbra 7.

My home box has limited resource. I assigned Zimbra VM with 2 CPU and 2GB RAM and 20GB disk.

For KVM server at DataCenter, I assigned it with 2 CPU and 3GB RAM and 20GB disk.
