CentOS 6.0 Zimbra 7.1.1 Open Source Edition install

Update 8/12/2011:
Good news! CentOS 6.x is out of beta and in stable with version 7.1.2 from HERE. In fact, you may just want to check their download page.

I wanted to take a peak at what is going on with Zimbra and CentOS 6 install capability. Currently, CentOS 6/RHEL 6 is listed as a beta for Zimbra 7.x installs. To to be deterred, I grabbed the beta download from the beta download page

wget http://files2.zimbra.com/downloads/7.1.1_GA/zcs-7.1.1_GA_3196.RHEL6_64.20110527010625.tgz

Test server is decent Dell Poweredge 2950 type II with 2 Intel quad core E5335 with 6GB RAM, RAID 1 for / (qty 2x80GB SATA) and RAID 5 for /opt (qty 4x500 SATA)
CentOS 6.0 x86_64 install was done as a "web server" install to provide most options I thought I would need as a start for the Zimbra install.

Note: I always suggest to install OMSA on any Dell server!

After the system is setup make sure that services that will interfere with Zimbra installed version are stopped and will not turn on at boot time:

chkconfig postfix off
service postfix stop
chkconfig httpd off
service httpd stop
tar -xzvf zcs-7.1.1_GA_3196.RHEL6_64.20110527010625.tgz
cd zcs-7.1.1_GA_3196.RHEL6_64.20110527010625
./install.sh

64 bit install but the installer still wants "libstdc++-4.4.4-13.el6.i686" installed.?

yum install libstdc++-4.4.4-13.el6.i686

Read Zimbra install info seems to be the moral of the story.

Finally installed with:

./install.sh --platform-override

followed prompts. Initial failure with log message with many:

sudo: sorry, you must have a tty to run sudo

Ran visudo to temporarily comment the "Defaults    requiretty" line and then ran:

/opt/zimbra/libexec/zmsetup.pl

To complete the install. Reboot just to make sure everything starts and begin the setup process. Now on to the much harder Zimbra setup!

Wow, still not done! Zimbra zmconfigd seems to need netcat, but is not a rpm requirement.??

yum -y install nc

Also, the install seems to need a patch before I can start working:

wget http://files2.zimbra.com/downloads/7.1.1_GA/zcs-patch-7.1.1_GA_3213.tgz
