Admin Field Guide: Installation & Configuration

Here's some gotchas we hear about from the Zimbra Community when installing and configuring ZCS. Hope this makes for smooth sailing!

What are the pre-requirements for installing the Zimbra server, how do I avoid install hassles?

  • Do you have all the install pre-req's ironed out like compat-libstc++, selinux disabled, and port conflicts resolved. Installation will check and fail on any of these condition.
  • Pre-requirement: For Red Hat Enterprise, Fedora Core and SuSE operating systems, the server must also have the following installed
    • NPTL. Native POSIX Thread Library
    • Sudo. Superuser, required to delegate admins.
    • libidn. For internationalizing domain names in applications (IDNA)
    • cURL. A command line tool for transferring files with URL syntax
    • fetchmail. A remote-mail retrieval and forwarding utility used for on-demand TCIP/IP links.
    • GMP. GNU Multiple-Precision Library.
    • compat-libstdcc++-33. Compatibility Standard C++ libraries. ( NOTE: The 32-bit version of the compat-libstdc rpm package is required for both 32-bit or 64-bit servers. )
    • For Red Hat Enterprise only: compatlibstdcc++-296

Avoiding conflicts: what are the default port configurations when Zimbra is installed?

Default port usage:

  • Postfix 25
  • HTTP 80
  • POP3 110
  • IMAP 143
  • LDAP 389
  • HTTPS 443
  • Tomcat IMAP SSL 993
  • Tomcat POP SSL 995
  • Tomcat LMTP 7025

How do I make sure that DNS is configured correctly?

  • Overview of MTA and DNS
  • Make sure the default domain supplied in the DNS wizard is the actual email domain and not the FQDN of the box

What are the top issues affecting performance?

  • Make sure that your client machines satisfy the system requirements for systems specs, operating system, and browser.
  • Make sure the server machines meet the system requirements for hardware and operating system; size your hardware with growth in mind!
  • Review the system requirements (PDF)
    • Evaluation and testing: Intel/AMD 32-bit CPU 1.5 GHz, 1 GB RAM, 5 GB free disk space for software and logs, mail storage space
    • Production: Intel/AMD CPU 32-bit 2.0+ GHz, 2+ GB RAM, 10 GB free disk space for software and logs, mail storage space.
      • RAID-5 not recommended for installations with more than 100 accounts

How does the license key work?

  • The license key is provided to you in the Network trial registration email from the Sales Team.
  • When you do the installation you will automatically be provided a single user license (admin) to enable the install.
  • From the Admin UI (Global Settings / License / Update License) you can then apply the key to the trial system and provision up to 50 accounts for the life of the trial.
  • After the trial expires you will no longer be able to add new accounts but the ones you already have provisioned may still work for some time.
  • Existing customers with license issues can always visit the Support Portal

I can't get to the Admin UI when I type in the URL into my browser.

  • Make sure the URL connects to the Admin UI using SSL: "https" and to port ":7071" by default.

How do I install the Network Edition Virtual Appliance?

We use Active Directory, what level of "access" into AD does Zimbra need to authenticate users?

  • In order for Zimbra to use external AD/LDAP for authentication and/or GAL, you need to create a user that can see all user objects in the AD schema.
  • Configuration of external auth/GAL is by means of an easy wizard in the Admin UI.

How do I access the Exchange migration tools?

  • In the Admin UI select the Wizard tab, you will find migration tools and documentation
