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:
(comment "Defaults requiretty")
:x! (to force vi to save over the readonly file)
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!
