This is a very short post about a little script I did to create remove virtual hosts easily.

I’ve found a couple of scripts (http://patrickgibson.com/utilities/virtualhost/, http://www.tamdenholm.com/portfolio/apache)  to do this but they didn’t worked right, I’m using Ubuntu Karmic, maybe thats why. However instead of fixing those scripts I went to my vim editor and started typing this, I’ve spent about 2 hours writing this while I was watching a crappy tv program, but in the end it worked, it surely contains some bugs, or it is unsafe to run it, I just wanted to share this.

Here is a screenshot of the program running

I needed to update the php version of a centos 4 box, so this is what I did:

I’ve decided to go for the easy way, using the remi repo, so first I’ve Downloaded the Extra Packages for Enterprise Linux (EPEL)

[root@box php5.3]# wget http://download.fedora.redhat.com/pub/epel/4/i386/epel-release-4-9.noarch.rpm

Then the remi repo:

[root@box php5.3]# wget http://rpms.famillecollet.com/enterprise/remi-release-4.rpm
--13:08:21--  http://rpms.famillecollet.com/enterprise/remi-release-4.rpm

13:08:22 (32.41 KB/s) - `remi-release-4.rpm' saved [5120/5120]

Then I’ve upgraded both repos:

[root@box php5.3]# rpm -Uvh remi-release-4*.rpm epel-release-4*.rpm
warning: remi-release-4.rpm: V3 DSA signature: NOKEY, key ID 00f97f56

and after that I downloaded the remi repo file for Yum:

[root@box php5.3]# cd /etc/yum.repos.d/
[root@box yum.repos.d]# wget http://rpms.famillecollet.com/remi-enterprise.repo
