When Plesk fails to upgrade

I’ve had this issue before: you get a new server, the image is a few revisions behind the current release and your first line of business is to upgrade the system.

A few minutes later you check and find that Plesk refuses to start. Bugger. Now what?

My Customer Support Gurus always know what to do, but in an effort to not disturb them at night here’s what they did to make it all work again. These instructions work on a CentOS 5 system with Plesk 9.0.1 installed.

/usr/local/psa/admin/sbin/autoinstaller --select-release-current --show-components | grep upgrade
tail -f /var/log/sw-cp-server/error_log
uname -a
cat /etc/redhat-release
wget -c http://kb.parallels.com/Attachments/12669/Attachments/sw-cp-server-1.0-6.201004011130.centos5.x86_64.rpm
rpm -Uhv sw-cp-server-1.0-6.201004011130.centos5.x86_64.rpm
/etc/init.d/psa stopall
/etc/init.d/psa start

Voila – Plesk works again 😉
