Plesk "The component was not installed" for all services.

This is a really small blog post, but it’s an issue I wanted to share - so hopefully anyone who comes across this issue themselves can avoid the mistake I made!

Basically, we noticed that one of our older Plesk servers seemed to have lost basic functionality like editing DNS zones, or accessing PHPMyAdmin or Webmail.

When going to Tools & Settings > Server Components we noticed that next to all the services (components), there was the message “The component was not installed”.

Interestingly, when accessing the server via SSH, the servers were installed, and functioning correct (websites were accessible, DNS was querying etc).

Sadly, I jumped straight to the wrong conclusion, and thought that a recent automatic update of Plesk had failed, and that the PSA services had been corrupted. I was wrong.

I ran the Plesk bootstrapper. If anyone is familiar with this, you’ll understand the pain I was going through. Two hours later, and the issue was not resolved. What do you try next?

Well, after the bootstrapper failed to fix the issue, I just tried running “yum update” to see if there were any package updates etc.

BOOM! There it was!

Thread died in Berkeley DB library DB_RUNRECOVERY: Fatal error, run database recovery

Great! That’s a really easy fix.

rm -f /var/lib/rpm/__* rpm –rebuilddb yum clean all

Now, check back in Plesk, and all functionality and the Server Components list will be fixed!
