Configuring Kolab with setup-kolab

After having installed kolab (following the appropriate install guide in this knowledge base) it needs to be configured. The script ‘setup-kolab’ is distributed with the out-of-the-box installation and is taking care of the basic configuration, but a successful configuration is depending on the environment that Kolab is installed into. Many aspects and variables will have an impact on the configuration. This guide is only touching on the absolute basics. For information and assistance with more complex installation scenarios, please contact sales@kolabsystems.com

The Kolab server host needs to have a fully qualified domain name as hostname:

[root@maipo ~]# hostname
maipo.kolab.io

If the server needs to communicate with the internet, the network needs to be configured to ensure that reverse DNS lookups are responded to in an appropriate fashion:

[root@maipo ~]# host maipo.kolab.io
maipo.kolab.io has address 95.135.58.46
[root@maipo ~]# host 95.135.58.46
46.58.135.95.in-addr.arpa domain name pointer maipo.kolab.io.

If applicable, ‘selinux’ needs to be in ‘permissive’ mode:

[root@maipo ~]# getenforce
Permissive

If firewalls are enabled, the appropriate ports need to be open. The following is a standard list of ports. Most of those are opened in a default linux installation, but more configuration of firewalls can be necessary:

25 - SMTP
80 - HTTP
110 - POP3
143 - IMAP
443 - HTTPS
465 - SMTPS (Not configured in default setup)
587 - Submission
993 - IMAPS
995 - POP3S
4190 - Sieve

Running the script ‘setup-kolab’ is going to configure the installed components with a standard configuration and create the needed users, roles and databases. Along the way it will ask for input of desired usernames and passwords – though suggestions are provided:

[root@maipo ~]# setup-kolab
Created symlink from /etc/systemd/system/multi-user.target.wants/guam.service to /usr/lib/systemd/system/guam.service.

Please supply a Cyrus Administrator password. This password is used by Kolab to
execute administrative tasks in Cyrus IMAP. You may also need the password
yourself to troubleshoot Cyrus IMAP and/or perform other administrative tasks
against Cyrus IMAP directly.

What MySQL server are we setting up?
- 1: Existing MySQL server (with root password already set).
- 2: New MySQL server (needs to be initialized).
Choice: 2

Please supply a root password for MySQL. This password will be the administrative
user for this MySQL server, and it should be kept a secret. After this setup
process has completed, Kolab is going to discard and forget about this password,
but you will need it for administrative tasks in MySQL.

[root@maipo ~]#

If so desired, it is possible to have ‘setup-kolab’ select the default values:

[root@maipo ~]# setup-kolab --default --timezone=Europe/Zurich --mysqlserver=new --directory-manager-pwd=MyAdminPassword
