Centos 7 + ZCS 8.7.11 don't work

Postby Despair » Thu Sep 28, 2017 9:28 am

Hello!
I install Zimbra on my new server, but it's not working. In admin-panel status of server and applications is online, and no error in /var/log/messages, var/log/maillog. I have no errors during installation, only dns-name of server, but this error was maked because this server not written in dns-server.
So, Admin-panel is working, but when I try visit authorisation-page - it's not found!
Firewall is off. Log is empty. tell me please, where may be error?

You need valid DNS A & MX records for your server (as mentioned in the documentation), do you have those and is your server behind a firewall/NAT or on a Public IP?

No, it will not work. As I've already mentioned you need valid DNS A & MX records and as you're behind a NAT router you need to follow the wiki article on Split DNS: https://wiki.zimbra.com/wiki/Split_DNS - that will tell you everything you need to know and how to verify it's correct.

Thank you,I did not manage to run the bind as in the specified article
Failed to start Berkeley Internet Name Domain (DNS).

I'll read about this, about result I will write here

I should mention that you can also disable the ZCS dnscache if you're going to run a caching DNS server on your LAN. For CentOS7 here's an article (one of many) from the internet: http://linuxpitstop.com/dns-server-setu ... s-7-linux/ - there's also tons of them for Ubuntu. I tend to prefer PowerDNS Server & Recursor myself as it's easier to set-up and gives better performance.

For my installation I had to install dnsmasq following the second part of the split dns wiki, Bind was too overkill for my skillset ... then performed a Zimbra install excluding the dnscache service and it was all good with no warning during installation on DNS resolution etc.... hope it helps
