This is a long post. There’s a lot of stuff in here. There’s no quick and dirty how-to. It’s a diagnostic record. Hope it helps. This morning I saw log entries I’ve never noticed before. They seem to have started 9 hours ago. First, this email arrived. cliff2 is one one two hosts behind cliff: [7:25 pro05 dvl ~] % host cliff cliff.int.unixathome.org has address 10.55.0.44 cliff.int.unixathome.org has address 10.55.0.14 In this post: […]

I broke my FreeBSD MySQL jail; got it working again by using a snapshot

I was upgrading a host the other day. The mysql02 (that’s the hostname) jail broke. I suspect I did something like upgrading the package while the server was in use. I noticed LibreNMS wasn’t running: *** /var/log/librenms/librenms-service.log *** Feb 10 18:37:30 besser librenms[23957]: MainThread(CRITICAL):ERROR: Could not connect to MySQL database!

Poudriere symlinks for repos

Leave a Comment / FreeBSD, Open Source, pkg / By /

I have some repos which are specific to certain tasks. Every time I upgrade major version (as I just did from FreeBSD 14.3 to FreeBSD 15.0), I need to remember to go in and add in those symlinks. I forget just about every time. I get errors like this: # pkg upgrade -f Updating local repository catalogue… pkg: Repository local has a wrong packagesite, need to re-create database pkg: Failed to fetch https://fedex.int.unixathome.org/packages/FreeBSD:15:amd64-mysql84//meta.conf:

FreeBSD 15.0 – after upgrade, installing my own packages

Leave a Comment / FreeBSD, Open Source, pkg / By /

I build my own FreeBSD packages using poudriere. The chicken-and-egg situation: I can’t build FreeBSD 15.0 packages until I’m on FreeBSD 15.0 – and upgrading to FreeBSD 15 involves a step of upgrading all your packages before the final steps of the upgrade. What do I do? I disable my repos and enable the FreeBSD repos. If you’re using your own repos, you should already know how to do this. In this post:

Upgrading a FreeBSD 14.3 host to FreeBSD 15.0

Leave a Comment / FreeBSD, freebsd-update, Open Source / By /

Today, I again mused about FreeBSD 15.0 and pkgbase. It’s freezing outside, and I’m going for an Indian dinner in about 2 hours. Let’s see if I can break r730-01 with my upgrade attempt. In this post: FreeBSD 14.3 (starting point) FreeBSD 15.0 (target) The docs I’m starting with official docs: FreeBSD 15.0-RELEASE Installation Instructions That directs me to Upgrading from Previous Releases of FreeBSD And then the binary update via Upgrading Using

This post is related to Upgrading a FreeBSD 14.3 host to FreeBSD 15.0 which I wrote and ran earlier this evening. I’m now back from my Indian dinner and watching the Superbowl (0:15 left in the 2nd half). I was updating r730-01 and got to the point of where I need to updated the packages on the host. I couldn’t do that. I hope my own FreeBSD pkg repo. What I did before

Migrating a MySQL 8.0 jail to a new MySQL 8.4 jail – 2nd attempt

Leave a Comment / FreeBSD, mySQL, Open Source / By /

Yesterday, I ran my first attempt at Migrating a MySQL 8.0 jail to a new MySQL 8.4 jail – it went better than I expected. However, I spent more time with MySQL than either the data transfer or the MySQL upgrade itself. Today, that should go faster because I already know the fix and have saved the password updates. Today, I’m going to try again, and hopefully this time will be the last
