Zimbra Cluster on RHEL5

[mickkael]

Hi all,

I'm installing a Zimbra Community Server on single node cluster mode.
OS is RHEL5

I used some workarounds to arrive to the cluster configuration, but when I execute postinstall.pl, I got this error:

Installing RPMs

... rpm -i ../zcs-cluster/zimbra-cluster-4.5.4_GA_763.RHEL4-20070411174055.i386.rpm

erreur: Dépendances requises:

magma est nécessaire pour zimbra-cluster-4.5.4_GA_763.RHEL4-20070411174055.i386

With my Google-researches, I don't think magma exist in the RHEL5 architecture. Do you have a workaround ?

I install a trial version at this time and plan to buy a full license next month and to put it on production state. I hope RHEL5 will be supported next month, but I want to test cluster mode yet.

Thanks.

Here are the workarounds for installing zimbra on RHEL5. It might be helpful for someone:

before installing anything:
yum remove sendmail
yum install openssl097a compat-libstdc++-296 compat-libstdc++-33
visudo (comment "Defaults requiretty")

With this zimbra installation works perfectly on RHEL5, except the cluster installation.

Thanks!

Would you be willing to add that to the cluster wiki page?

Thanks

The workaround is for installing ZCS on each server of the node. I'm still searching for a workaround / rpm package in order to complete the cluster configuration.

cluster configuration is made by zimbra-cluster-4.5.4_GA_763.RHEL4-20070411174055.i386.rpm
this RPM need to resolve dependancies with "magma", but this packet don't exist for RHEL5.

Is there a beta version of zimbra-cluster package for RHEL5 ???


Without any solution on this, I think I will install Open-source Edition with Heartbeat and DRDB, because HA/clustering is the only functionnality I need in Network Edition. RHEL5 is essential because my RAID card isn't supported by RHEL4.

We're gonna be releasing 5 support very very soon.

We're gonna be releasing 5 support very very soon.

very very soon is tommorow or next month ?

thanks

[jholder]

We're doing our very final QA testing. Once that's done, we'll release it.

I'm not permitted to give our internal target date, but it's soon enough so that if you take your weekend off, and come back, you'll be happy

[mickkael]

Great !

I will be your first tester then !

Where will I see the Announcement ? Forum, Blog, direct in download section ?

Thanks

I'm puzzled...
You need HA but you don't need backup ?!

RHEL5 is essential because my RAID card isn't supported by RHEL4.

Can you tell which brand/model, just to be sure I don't have customers buying it ?

All of that...

Thanks all, especially: mickkael(above), robbyt, jholder, phoenix, and dealt.
This information given above is essential for anyone doing upgrades!

Get/Show RHEL 4 Zimbra relases will install on RHEL 5:
Installing RHEL 5 with the intension of installing Zimbra RHEL 4 release on it.

sendmail can be deselected when installing by insuring it is not checked under Base System | Base, as well as Servers | Mail Server, it wont matter though because fetchmail is dependant on it, so it will install anyway.
openssl097a compat-libstdc++-296 compat-libstdc++-33 are available when installing under Base System | Legacy software support.
fetchmail - under Applications | Text-based Internet
gmp : gmp-devel under Development

yum remove sendmail
# you cant do this because it will uninstall fetchmail as well due to dependancies
yum install openssl097a compat-libstdc++-296 compat-libstdc++-33
# not needed if you install them during install as noted above
visudo (comment "Defaults requiretty")
# the man page for visudo is there, but the command doesnt seem to work.

as long as you are the only user modifying the file you can:
su
vi /etc/Sudoers
(comment "Defaults requiretty")
:x! (to force vi to save over the readonly file)

vi /etc/hosts
verify:
127.0.0.1 localhost.localdomain localhost
xxx.xxx.x.x mail.host.com mail

I cheat and use the GUI for the next few steps:
RHEL5 automatically turns on SELinux and firewall ... it doesnt even ask during install anymore... so
System | Administration | Security Level and Firewall
Set Firewall to disabled, Set SELinux to Disabled

Install Zimbra 3.0.1 GA OSS

This is installed and working fine on RHEL 5. I now need to figure out how to get my old info on this machine from a different server.

Discussion of how to get Zimbra moved from one PC to another has been moved to this new thread with smiles to all the employees/moderators that yell at people for tagging onto old posts with new/different problems.
Please smile back by coming to the new thread and helping me!
