Upgrade CentOS 6 to 7 with Upgrade Tools
I decided to try the upgrade process from EL 6 to 7 on the servers I used in my previous blog post “Windows (CIFS) fileshares using GlusterFS and CTDB for Highly available data” Following the instructions here I found the process fairly painless. However there were 1 or two little niggles which caused various issues which I will detail here. The servers were minimal CentOS 6.5 installs, with Gluster volumes shared via CTDB.
Installing dig on a CentOS or Red Hat machine
Gone are the days where we install nslookup for DNS resolution testing, the new(ish) kid on the block is dig. Although maybe not installed by default, it can be installed quite easily from yum, however it comes bundled with a number of tools so the package name isn’t all that obvious. [root@server ~]# yum install bind-utils Will do the trick, now how to use it? [root@server ~]# dig @nameserver address.com
Why I'm uninstalling Ubuntu
I wouldn’t normally write about this kind of move, but I’m in a position where I feel I have to. A little over a year ago I made a decision to move from Fedora to Ubuntu, it wasn’t a decision that was easy after all I have been using Fedora since its first release, and Red Hat since around version 5. Needless to say I was (and still am at heart) a die hard Red Hat fan.
