I had to take the DEOSS server off-line for a couple of hours this evening for a routine server operating system update. Essentially it involved upgrading its underlying Debian GNU\/Linux operating system from version 10 (“buster” aka “old stable”) to version 11 (“bullseye” aka “stable”). <\/p>\n
As Debian upgrades go, this proved to be one of my less eventful ones. Pretty much everything upgraded as expected. It also gave me the opportunity to revisit some configuration issues. <\/p>\n
So I’m pleased to report that after several reboots and some fairly extensive server-side testing, the e-mail server and the web server both upgraded successfully and appear to be functioning correctly. And there certainly seems to be a significant improvement in web server performance.<\/p>\n
This upgrade should also be good news for those with sites needing updated plug-ins. Some plug-ins refused to upgrade on the version of PHP shipped with Debian 10. Debian 11 has a later version of PHP, which allows these plug-ins to update correctly. <\/p>\n
I have subsequently visited and logged-in to all sites hosted on this server and successfully updated all plug-ins. Everything appears to be functioning correctly. <\/p>\n
However, with an upgrade of this magnitude, there may still be a few configuration issues and tweaks needed over the next few days. So, if you are a DEOSS customer and you are still having any issues, please contact me through the normal channels.<\/p>\n","protected":false},"excerpt":{"rendered":"
