Just a quick tip today, should help all of you who are setting up their very first Linux/Apache/PHP/MySQL (LAMP) webserver.

To list all the Apache modules that were loaded upon httpd start, use the apachectl -M command:

root@webserver1# apachectl -M

Have recently found out that Oracle Linux is now completely free to get and to use, meaning that you’ll only have to pay for commercial support should you decide you need it.

Oracle has even gone as far as create a special page converting CentOS users into Oracle Linux followers: Oracle Linux – A better alternative.

What do you think?

Will you be switching?

Have you tried it yet?

Let me know in the commetns area, thanks!

I’ve got a few RedHat and CentOS VMs running on internal network of my server, and since updating them quite regularly is a habit I thought this little piece of advice will help all of you who run VMs in a similar scenario.

To make yum command use proxy, your best best is to edit /etc/yum.conf and add your proxy server reference:

proxy=http://192.168.3.1:3128

You don’t have to restart anything but it may be a good idea to do yum clean all and then yum check-update:

[root@testvm1 ~]# yum check-update
