import a bunch of pkgsrc articles from the old pkgsrc.se wiki

**LAMP** is a an acronym for a combined set of software to run a Webserver containig following Software Products: **Apache, Mysql Perl, Python or PHP**. The "L" stands for Linux, therefore there is also an acronym named **WAMP** representing the Windows Operating System. This also means that the title of this article is misleading. The approach is to install the same combined set of software, but using NetBSD as the Operating System instead of Linux. 

We will install all components using pkgsrc, building all packages from source. An installation using existing binaries provided by ftp.netbsd.org is not possible.

#  Installing the Apache webserver 

The new Apache 2.2 server comes with two different threading models from which [prefork](http://httpd.apache.org/docs/2.2/mod/prefork.html) is installed by default. It is **not** recommended to use the Worker model, if you wish to use Apache and PHP. As that is the case, we will install a default Apache 2.2 server. 
    
# cd /usr/pkgsrc/www/apache22
    # make install clean clean-depends
    

This will install the Apache 2.2 server and all it's dependencies. The package currently depends on 10 other packages like perl, gmake and libtool to name a few. All dependencies are build before the Apache webserver is build, otherwise it wouldn't be dependencies. 

If your build was successful, you should now edit the Apache configuration file _`/usr/pkg/etc/httpd/httpd.conf`_ to fit your needs. At least set the `Listen` Attribute and your `ServerName`. Please ensure that if your machines hostname does not globally resolve, to put it into your `/etc/hosts` file, otherwise Apache will refuse to start. 

If you wish to start the Apache webserver at boottime, please copy the rc.d example script from `/usr/pkg/share/examples/rc.d/apache` to `/etc/rc.d` and then add `apache=yes` to your `/etc/rc.conf` file.   

    
    # cp /usr/pkg/share/examples/rc.d/apache /etc/rc.d
    

If you want to copy the rc.d scripts automatically with pkgsrc, you can use: 
    
    PKG_RCD_SCRIPTS=YES 
    

in your /etc/mk.conf 

  
You could now start, stop and restart the Apache Webserver using _apachectl_ or using boot script _/etc/rc.d/apache_

To start the Server enter: 
    
    # apachectl start
    

or 
    
    # /etc/rc.d/apache start
    

To stop the server, substitute start with stop. If you're running a production server, pay attention to the [apachectl graceful](http://httpd.apache.org/docs/2.0/programs/apachectl.html) option. 

#  Installing MySQL 

You can skip this part, if you don't want to install a MySQL Server. To install the MySQL Server enter: 
    
    # cd /usr/pkgsrc/databases/mysql5-server
    # make install clean clean-depends
    

This will install the mysql server and all it's dependencies, like the mysql client. 

##  Configuring the MySQL server 

Please copy the example start script to /etc/rc.d 
    
    # cp /usr/pkg/share/examples/rc.d/mysqld /etc/rc.d
    

and add **mysqld=yes** to your **/etc/rc.conf**

You can now start, stop and restart the MySQL server using 
    
    # /etc/rc.d/mysqld start
    

to start and respectively stop and restart. 

The default mysql server database root password is empty. For security reasons, you should set your root password as soon as possible. 

You can pass most of the Options to the Server via the file /etc/my.cnf. If you want the Server to listen only on localhost, for instance, create _/etc/my.cnf_ and add 
    
    [mysqld]
    port=3306
    bind-address=127.0.0.1
    

and restart your mysql server. To check, if your mysql server is really listening only on localhost, use [[basics/sockstat]]. 
    

    # sockstat -l
    

For much more Options, consider reading the MySQL [Documentation](http://dev.mysql.com/doc/refman/5.0/en/). 


#  Installing the PHP Module for Apache
    
    # cd /usr/pkgsrc/www/ap-php
    # make install clean
    

This will install by default the latest Version of PHP 5.x and the PHP5 Module for Apache 2.2 

##  Configuring PHP 

You should now add the Module and the PHP Handlers to your Apache Configuration File `/usr/pkg/etc/httpd/httpd.conf`

Add following lines: 
    
    LoadModule php5_module /usr/pkg/lib/httpd/mod_php5.so
    

and 
    
    AddType application/x-httpd-php .php
    

and if you wish 
    
    DirectoryIndex index.html index.php
    

#  Installing the MySQL module for PHP 

This step is important and enables you to make mysql database connections from your php skript. 
    
    cd /usr/pkgsrc/databases/php-mysql/
    make install clean
    

Now edit `/usr/pkg/etc/php.ini` and add the line 
    
    extension=mysql.so
    

You need this to enable mysql functions in your php module. 

Now restart your Apache webserver. To test, if PHP is working, create a small file called test.php in your document root directory, which is by default `/usr/pkg/share/httpd/htdocs`, containing only one line with the function phpinfo(). 
    
    <?php phpinfo(); ?>
    

if you use php5 and wish to use short tags like `<? phpinfo() ?>`, then edit your `/usr/pkg/etc/php.ini` file and change option `short_open_tag = Off `to `On` to make this line working. In PHP5 short_open_tag is off by default. 

Open your browser and point it to this url: 
    
    http://127.0.0.1/test.php
    

You should now see a website with information regarding your PHP installation and a table named mysql, in the middle of the document, with mysql informations. 

That's it. You can now install software like a [phpMyAdmin](http://pkgsrc.se/databases/phpmyadmin), or a [Wiki](http://www.mediawiki.org). Have Fun.
