Zimbra Upgrade Complains About Hosts File
When upgrading Zimbra, one of the first things it does is check your hosts file for two entries. It needs a valid localhost entry (the mysql setup is sensitive about this) and it needs a valid host FQDN entry for the server itself.
It wants to see something like this:
192.168.12.5 mail.xxxxxxxxxxx.com mail 127.0.0.1 localhost.localdomain localhost
The upgrade script kept complaining that my hosts file was incorrect, but those two entries where there and they looked fine.
Here's the error (sic):
ERROR: Installation can not proceeed. Please fix your /etc/hosts file
It turned out that the problem was with the other entries I had in my hosts file pointing to a different host and for my IP6 entries for local host. The install script uses a simple regex to look for the two entries it wants and errors if it finds something else.
The workaround was to put a # (remark) at the beginning of all of the OTHER hosts file entries, then the script would run.
It now looks like this:
192.168.12.5 mail.xxxxxxxxxxx.com mail 127.0.0.1 localhost.localdomain localhost # The following lines are desirable for IPv6 capable hosts #::1 ip6-localhost ip6-loopback #fe00::0 ip6-localnet #ff00::0 ip6-mcastprefix #ff02::1 ip6-allnodes #ff02::2 ip6-allrouters #ff02::3 ip6-allhosts
After I did that, the upgrade script ran fine. When everything was done, I removed the # entries and was back to normal. Or at least as normal as I get...
