These past few days I've been working a bit with Linux CentOS, and although the truth I do not like this fork in Redhat I had to investigate and make a couple of interesting experiments, like a USB drive that booteable arme with the installer for CentOS 5.1 make the facilities more quickly from the USB, but at the end of the day the bottleneck proved updates rpm's with Yum.

Part slower / boring for the installation of systems based on Redhat is the update repositories, as long as install any version of CentOS, Fedora or Redhat I recommend you upgrade the operating system via YUM. To upgrade our system, but we do not need to type: 


  [root @ mail01 ~] # yum update



With this system update Yum begins to download the metadata from the repositories, but unlike Apt, Yum also downloads the headers of each new or updated package.

One way to achieve speed up this process is connected to the Internet through a proxy server, this way we will always have a copy of the packages stored locally in the cache of squid. Another way to accelerate the transfer of a parcel CentOS is through the installation of a repository on the LAN.

But in my case we already have a proxy in the company, so let's see how to configure the proxy to Yum.
Edit the file yum.conf; 


  [root @ mail01 ~] # vim / etc / yum.conf



Inside the file add three lines to the configuration of proxy and the user (if the proxy requires authentication).

file: / etc / yum.conf

[main]
cachedir = / var / cache / yum
keepcache = 1
debuglevel = 2
logfile = / var / log / yum.log
pkgpolicy newest =
distroverpkg = redhat-release
tolerant = 1
exactarch = 1
Obsolete = 1
gpgcheck = 1
plugins = 1
metadata_expire = 1800

proxy = http://proxy.guatewireless.org:3128/
proxy_username = yum
proxy_password = yum
# PUT YOUR REPOS HERE OR IN separate files named file.repo
# In / etc / yum.repos.d

That's it from now on Yum repositories and update its software from entire rpm's via the proxy server.

YUM this certainly far from being as efficient as Apt, but not to get into trouble installing apt for rpm packages that there is no other use Yum. In the first installation provided the download was quite slow, but the other software updates have been downloaded from the proxy in a matter of minutes.

Incidentally, today I started to tap into the css to put the code on a black background, that is?
