What step 17. means is to disable certain services that may conflict with Zimbra. For example, you dont' want another mail server listening on port 25, as Zimbra will want to use that. So whatever this guide is saying, is to disable X services. I prefer cmd-line tools, so one way to see, and enable/disable, services starting and not being enabled, is "chkconfig".
So "chkconfig --list" will show you all services installed, and if they are set to run, what runlevel. Let us assume that you have a mail server installed and/or running. Could be sendmail, could be postfix, could be exim. So a "chkconfig --list|grep mail" will tell you if sendmail is installed, and if it is running.
"chkconfig --list|grep mail
sendmail 0: off 1: off 2: off 3: off 4: off 5: off 6: off"
And if it was enabled, this command would disable it at all runlevels, with the 2nd command shutting it down (if it is running).
# chkconfig --level 2345 sendmail off
# /etc/init.d/sendmail stop
Same for apache or any other webserver... anything listening on port 80 will conflict with Zimbra. HTH... |
