WARNING: yum overwriting postfix (SOLVED!!) Having fought for many days to configure my perfect server, I found that the nightly yum update had overwritten my special (ie Falko) version of Postfix. To sort out the resulting problems I had to uninstall all versions of Postfix and reinstall from my locallly built RPM. I then had to uninstall ISPconfig3, delete the dbispconfig database and install ISPconfig3 again. Hopefully to prevent this happening again the solution is to edit /etc/yum.conf and in the [main] section add the line 'exclude="postfix"' so that yum doesn't try an upgrade agan. Has anyone had the same problem? Can anyone confirm this is correct?
I had this problem with CentOS, but on my recent Fedora 12 server it's no longer an issue, postfix is built with mysql support in the Fedora repos. One thing I didn't try but thought about was doing a yum --nogpgcheck localinstall <custom postfix rpm> thinking that might stop yum from updating from the repos. But since I went to Fedora it's moot, and I never tried that solution.
That didn't work. First thing this morning I checked the mail logs etc and found Postfix errors (eg "fatal: unsupported dictionary type: mysql") Does anyone have any solution? --- the good new is that now that I have discovered why it broke, I don't have to uninstall/reinstall IPSConfig. Now I just run: Code: cp /etc/postfix/main.cf /etc/postfix/main.cf.sql # save the good version of the config file /etc/init.d/killall # stop all services yum remove postfix cd /usr/src/redhat/RPMS/x86_64 rpm -ivh postfix-2.3.3-2.1.x86_64.rpm cp /etc/postfix/main.cf.sql /etc/postfix/main.cf # restore the good version of the config file then go for a reboot to restart all services At a guess I could get away with just stopping postfix and restarting after the reinstal instead of a reboot, but a reboot on this server only takes less than two minutes!
problem solved. the syntax for the 'exclude' line in yum should be Code: exclude=postfix-* While researching this I was interested to see that the CentOSPlus repository apparently contains postfix rpms compiled with mysql support. Anyone who wants to give that a go should follow the instructions here: http://wiki.centos.org/AdditionalResources/Repositories/CentOSPlus If that version works correctly, perhaps "the perfect server" Howto could be rewritten to enable the CetosPlus repository and avoid having to rebuild postfix?
