I completed an upgrade of Debian Lenny to Squeeze on a production database server over the weekend. It went quite well and I had zero downtime thanks to my secondary database servers running in-place. One of the biggest benefits to running Squeeze is that MySQL runs at version 5.1.49. Lenny only supports up to MySQL 5.0. Row-based-replication is safer to replicate data to other servers since all changes are replicated. Prior to MySQL 5.1.14, updates to the mySQL database were not replicated. They were updated via statements (e.g. GRANT, REVOKE). This can potentially cause data-consistency between the master and ... ]]> http://albertech.net/2011/10/upgrading-debian-lenny-to-squeeze-with-mysql-for-row-based-replication/feed/ 1 Tomcat 5.5 installation on Debian, fix for webapps http://albertech.net/2009/06/tomcat-debian-webapps-install/ http://albertech.net/2009/06/tomcat-debian-webapps-install/#comments Thu, 18 Jun 2009 21:36:34 +0000 admin http://albertech.net/?p=198 http://albertech.net/2009/06/tomcat-debian-webapps-install/feed/ 0 Debian: fixing GPG error on apt-get update http://albertech.net/2009/06/debian-fixing-gpg-error-on-apt-get-update/ http://albertech.net/2009/06/debian-fixing-gpg-error-on-apt-get-update/#comments Tue, 02 Jun 2009 22:14:39 +0000 admin http://albertech.net/?p=179 If you get a GPG error when doing an apt-get update, here's the quickest way to fix it.The error message looks similar to:

By default, it says "You may want to run apt-get update to correct these problems". The problem is, apt-get update doesn't fix the keys automagically.

Improved display support with SVGA driver Cut and paste from host onto the VMWare guest Automation of guest operating system commands Sync time Shrinking disk space Startup and shutdown scripts In order to install VMWARE tools on Debian, you will need to make sure you have the package "linux-headers-[kernel version]" installed. If not, you will get a prompt during the configuration asking for the path of the C header files. To find the version of your kernel, type in: uname -a It should say something like Linux infomine 2.6.26-2-amd64 (with your current CPU architecture at the end) **** NOTE: Do this at your own risk.
