Ok here's my notes so far:-
Zimbra uses the following ports, and will break any existing services that listen on them. Zimbra comes with a big health warning that it will trample over existing configurations so I decided to test on a minimal ClearOS clean install
Remote Queue Manager 22
Postfix 25
HTTP 80
POP3 110
IMAP 143
LDAP 389
HTTPS 443
Mailboxd IMAP SSL 993
Mailboxd POP SSL 995
Mailboxd LMTP 7025
Clean Install from ClearOS5.1SP1 ISO
Selected
* Graphical Console
* DHCP and local DNS servers
Complete the final Stage2 configuration when you reboot, via the graphical config. Configure hostname as the hostname (MX record) of your mail server (Zimbra checks this later)
Fire up putty and SSH in
#yum install sysstat
#wget
http://files2.zimbra.com/downloads/6.0.6_GA/zcs-6.0.6_GA_2324.RHEL5.20100406144520.tgz
#tar zxvf zcs-6.0.6_GA_2324.RHEL5.20100406144520.tgz
#cd zcs-6.0.6_GA_2324.RHEL5.20100406144520
#./install.sh --platform-override
Y to default services (enter)- > Ldap, logger, mta, snmp, store, apache, spell
Y to install even through not RHEL
RPM installs, may warn about MX record on hostname (this needs to be resolveable)
Port conflicts check OK
Menu, configure admin password, press 3,4,pass,'r'
Configuration complete, press 'a' to apply
Save config
Yes to system modified
Lots of additional config/installation for quite a while...wait until complete! [enter]
#su zimbra
#zmcontrol status
login to admin service on
https://servername:7071/zimbraAdmin
This is essentially very close to the original Zimbra Quick Start guide...see link for more details
http://www.zimbra.com/docs/ne/latest/single_server_install/quick_start.1.10.html
Zimbra-store needs 5GB free space before install! and 1GB RAM min, it's a real resource hog, and startup time on my VM was 5-10minutes
Potential options for an existing install? comments? TBC
#yum remove httpd, postfix, ldap, clamav, mysql, spamassasin
needs a correct FQDN as the hostname, in localhost
