-bash-3.2#

To fix that, you can simply type this in your SSH when logged in:

PS1="[\u@\h \W]\$ "

Update: Now its been almost a month running Linode and I strongly recommend this VPS company.
Update 2: If you plan to signup for LINODE, use my referral link, it will give you the same price but it will help me a lil http://www.linode.com/?r=587d6a71720a4606811a5710431462642c56bc21

So, I thought why not move to Ubuntu since it has just announced 10.04LTS (Long Term Support) in April 2010. Folks at iWeb were really nice to do a reinstall without any charges and also process a memory upgrade request at an amazing 50% discount.

Ubuntu 10.04 LTS

• Apache 2 version is 2.2.14
• PHP version is 5.3.2
• MySQL version is 5.1.41-3ubuntu12
• SVN (Subversion) version is 1.6.6

As a comparison CentOS 5.4 has the following versions

• Apache 2 version is 2.2.3
• PHP version is 5.1.6
• MySQL version is 5.0.77
• SVN (Subversion) version is 1.4.2

So if you are a PHP developer looking to deploy a Linux flavour on your new box, choose Ubuntu

sudo passwd

output will be something similar to this

root@vps:~# sudo passwd
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully

nano -w /etc/yum.repos.d/utterramblings.repo

(I prefer nano as I mentioned earlier in my posts but you can use vi or any other editor that you like)

Then paste the following code in the editor

[utterramblings]
name=Jason's Utter Ramblings Repo
baseurl=http://www.jasonlitka.com/media/EL$releasever/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka

Hit Ctrl+X and it will prompt you to save this file, you need to confirm this with punching Y

Now comes the last step, type the following and everything will be updated

yum update

Enjoy the latest packages

Note: PHP 5.3.0 is still not available in stable repos because the Zend Optimizer is still in Beta for that particular version.

Update: A newer version of this article is available at http://www.centosblog.com/2012/01/16/how-to-install-webmin-on-centos/

Earlier, I posted a how-to to Install Webmin on Ubuntu, now im going through the tutorial again but this time for CentOS.

Install dependancies before we proceed to install webmin

yum -y install perl-Net-SSLeay

Download the latest version of webmin

wget http://downloads.sourceforge.net/project/webadmin/webmin/1.500/webmin-1.500-1.noarch.rpm?use_mirror=ignum

Once it is downloaded, install the RPM using the following command

rpm -i webmin-1.500-1.noarch.rpm

No more steps required. Its installed
Go to your browser and access the control panel with valid ssh credentials

Unfortunately, CodeIgniter does not have support for Crontabs and I didn’t wanted to user wget in linux crontab to initiate unwanted requests.

I spent some time and came up with a solution. It uses

1. CodeIgniter backend
2. Does not modify any core architecture of CodeIgniter
3. Keeps configuration at one place

So enough of the summary and let me show you how its done.
Create a file (e.g. cron.php) in the same place as your index.php and system folder. Here is its code

/**

/*
|---------------------------------------------------------------
| CASTING argc AND argv INTO LOCAL VARIABLES
|---------------------------------------------------------------
|
*/
$argc = $_SERVER['argc'];
$argv = $_SERVER['argv'];

// INTERPRETTING INPUT
if ($argc > 1 && isset($argv[1])) {
$_SERVER['PATH_INFO'] 	= $argv[1];
$_SERVER['REQUEST_URI'] = $argv[1];
} else {
$_SERVER['PATH_INFO'] 	= '/crons/index';
$_SERVER['REQUEST_URI'] = '/crons/index';
}

/*
|---------------------------------------------------------------
| PHP SCRIPT EXECUTION TIME ('0' means Unlimited)
|---------------------------------------------------------------
|
*/
set_time_limit(0);

require_once('index.php');

/* End of file test.php */

Now, we need a controller e.g. test so the controller code could be something like this. Please note that normally we do not need to output anything from these controllers since they are doing some background work or sending emails but for the sake of giving an example, I will be output-ing something to elaborate the example.

/**

*/</code>

class Test extends Controller {

function __construct()
{
parent::Controller();
}

function index()
{
echo "testing from index \n";
}

function test() {
echo "testing from test \n";
}
}

Now execute crontab on linux command prompt

php /full-path-to-cron-file/cron.php /test/index

Voila! all you need now, is to setup the crontab like you normally do.
This code is not shared under any license so feel free to copy/modify/use it. Please link back to this website / post in any way e.g. direct link, credits etc.

P.S. The examples above user PHP5 constructor, If you need to execute this code on PHP4, please modify the constructors.

So this is what I did, its easy and this might help somebody.

nano /etc/apt/sources.list

I prefer nano editor but you can use any editor of your choice. Add these new lines at the end of the end of the file.

deb http://ppa.launchpad.net/monty/ubuntu gutsy main universe restricted multiverse
deb http://ppa.launchpad.net/smurf/ubuntu gutsy main universe restricted multiverse

(These packages were targeted for 7.10 so I will recommend using them and removing them from this list once you got the latest MySQL version)

Now run the following commands

apt-get update
apt-get upgrade

Note that you may need to do sudo prefix to these commands if you are using a non-root account. Now lets do the one last step, Installing MySQL 5.1

apt-get install mysql-server-5.1

Update: I have got another source to get even latest minor version of MySQL 5.1, just follow the above steps, then start over again and add following lines to “/etc/apt/sources.list” instead of the one above.

deb http://packages.dotdeb.org stable all
deb-src http://packages.dotdeb.org stable all

It worked for me on Ubuntu 8.10, im sure it will work for just any server version.

I am not a linux guru so if someone has a better option to upgrade to MySQL 5.1 or the latest version, please let me know.

After trying to install Apache, MySQL and PHP on Ubuntu 8.10 via several methods listed over the web. I opted for xampp package for linux.

It is as easy as ABC

Download the xampp linux package from their official website

wget http://nchc.dl.sourceforge.net/sourceforge/xampp/xampp-linux-1.7.tar.gz

(I have selected NCHC, Taiwan as the mirror to download this package, you may try another)

Extract the files

sudo tar xvfz xampp-linux-1.7.tar.gz -C /opt

Chmod the files to have nobody ownership

sudo chown -R nobody:root /opt/lampp/

Configure xampp security

sudo /opt/lampp/lampp security

Start xampp with this command

sudo /opt/lampp/lampp start

Stop xampp

sudo /opt/lampp/lampp stop

Restart xampp

sudo /opt/lampp/lampp restart

Login to ftp using the username nobody and the password that you have set up in the “xampp security”

To uninstall xampp

sudo rm -fr /opt/lampp

Enjoy!!
