imagemagick is one of the best library to work with image. recently i have to install it to our production server. here is what i did:

$ apt-get install imagemagick

it downloads the package and all it’s dependences from debian/ubuntu repository, and installed. now i have to install the support of php (as our product running on php)

$ apt-get install php5-imagick

then i restarted the apache server to take effect this new package installation. if your using php4 then the package name should be php4-imagick

$ /etc/init.d/apache2 restart

that’s all

if you need imagemagick for your ruby , you can install the librmagick-ruby package.

Nowadays, lots of php developers are thinking to move their development environment to linux. And I am writing this tutorial for them. As I like Debian GNU/Linux (www.debian.org) best and ubuntu (www.ubutnulinux.org) is now doing great, in this tutorial I am using the commands for debian & ubuntu.

Ok, now starting:

First on all let’s make a list of software a PHP developer need mostly:

1.Apache
2.PHP
3.Mysql
4.PHP IDE

Ok, let’s start with Apache. Debian & ubuntu use APT to manage the packages. You can easily install apache using apt, here is the command

Debian user:

su

Ubuntu user:

sudo su

Rest of the command ar same for both debian & ubuntu.

apt-get install apache2

It will install all the apache2 & all the related packages (software)
If you need to enable mod_rewrite, follow this link
Now install the PHP

Apt-get install php5 libapache2-mod-php5

This will install the php5 and configure your apache2 server for PHP. You don’t need to do anything.
Lets test the server, if it working ok.

touch /var/www/info.php

Chown www-data:www-data info.php

Now edit this info.php with your feviourate editor and add write code to show phpinfo():
and now browse http://localhost/info.php from your browser. Now check if all your requested library are installed.
if you need any more library, you can check if it already available on your debian/ubuntu package list.

apt-cache search php5-

then you will get the list of available php5 library. Now simple use this command to install it.

apt-get install php5-gd

(example, if you want to install php5 GD library)

Remember: after installing every extra packages, you must need to restart apache server

/etc/init.d/apache2 restart

Ok, so you have now apache2 and php5 installed system. Let’s install mysql:

apt-get install mysql-server-5.0 php5-mysql

It will install all the necessary packages to run mysql-server.
Now restart your apache to take effect.
Complete!!!! Server is allmost ready.
Now i am going to derive how you will transfer your old code to this new environment. Belive me it’s too simple, so don’t worry.

First of all copy your source code to /var/www, here is the details procedure:

mkdir /windows

Here we make a folder for C drive of windows to mount.
mount /dev/hda1 /windows
then we mount the C drive to windows folder (here i use hda1 as example, if your hdd is sata then it will be sda1)

cp -r windows/Apache2/htdocs/xyz /var/www

here we copied our xyz site to /var/www (in debian and ubuntu, default apache2 root folder is /var/www)

cd /var/www

chown -R www-data:www-data xyz

Now change the ownership to www-data

Now we need to move the mysql database, there is two way:

1.use phpmyadmin
2.simple copy the database from data folder
I am deriving the 2nd way.

cp -r /windows/Mysql/data/xyz /var/lib/mysql

chown -R mysql:mysql /var/lib/mysql/xyz

You are done.

PHP Ide for linux environment:

1.Zend ( i personaly use this)
2.PHPEd
3.PHPEclipse
4.quanta plus
5.emacs
6.vi
7.PHPedit

***I know this tutorial needs more edit, please make your comments if you got anything wrong, or missed anything. I want it a cool tutorial for php developers.

Here i am going to describe how to enable mod_rewrite in apache2.2 -specaily for debian.

In default installion of apache2.2 on debian never enable mod_rewrite default. So you may need to enable .

First install the apache2.2 with this command :
debian user please use “su” before start this process
ubuntu user please use “sudo su” before start this process

apt-get install apache2 (it will install apache 2.2)

now use locate to find if the mod_rewrite.so is availble on your server

updatedb
locate mod_rewrite.so


it will found in “/usr/lib/apache2/modules”

new apache follow some folders to enable and desuable mods.
so now do this:

cd /etc/apache2/mods-enabled
touch rewrite.load
gedit rewrite.load (you may use any editor to edit this file)

now paste this following line

LoadModule rewrite_module /usr/lib/apache2/modules/mod_rewrite.so

Then edit /etc/apache2/sites-available/000-default

Find the following

Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all

and change it to

Options Indexes FollowSymLinks MultiViews
AllowOverride all
Order allow,deny
allow from all

and finally restart Apache

/etc/init.d/apache2 restart

OK, you done

don’t forget to comment, if it works or not.

thanks.

A great post about subversion of hasin brother.

On the new version of subversion 1.4.3 u will need to do some thing more. svn-1.4.3 cann’t be install as service. U have take help from 3rd party tools.

Two of them are:

• SVNService is a free tool written by Magnus Norddahl (not found)
• SrvAny is avaliable free of charge from Microsoft

or u can use “sc” command to add subversion as service..

Here is the example:
sc create svnserve binpath= "c:\svnserve\svnserve.exe --service --root
c:\repos" displayname= "Subversion" depend= tcpip start= auto
These command must be entered as a single line.

Here bindpath is the where the svnserve.exe is installed, –root is the root directory of
repository, displayname is the name that will display on the windows service list, start = auto is used to start this service on system startup.

Hope it will help you
