INSTALLING LAMP - apache2-DJANGO.txt

sudo aptitude install apache2


Next up, we’ll test to see if PHP is working. In terminal, enter the following command to create a new document:

sudo nano /var/www/testing.php

Then, copy the following code:

<?php phpinfo(); ?>

Let’s test Apache to see if it’s serving properly. Open up a browser and direct it the following URL:

http://localhost/
defualt domain is 127.0.1.1cd



=================how to control apache2========================================
How do I start, restart, or stop Apache 2.x web server on Ubuntu Linux operating systems using command line options?

You can use any one of the following method to restart / start / stop your Apache (httpd) sever on Ubuntu:

	/etc/init.d/apache2 - A sys v init style script to start / stop / restart the Apache2 service under Debian or Ubuntu Linux.

	service command - This command work in most Linux distributions including Debian and Ubuntu.

	upstart command - Only works on latest version of Ubuntu.

	apache2ctl command - This method should work on all Linux and Unix like operating systems.

Method #1: /etc/init.d/apache2 command examples


You need to login as root user or use the sudo command to control Apache web-server.

Task: Start Apache 2 Server

# /etc/init.d/apache2 start

or
$ sudo /etc/init.d/apache2 start

Task: Restart Apache 2 Server

# /etc/init.d/apache2 restart

or
$ sudo /etc/init.d/apache2 restart

=======also:  sudo /usr/sbin/apachectl restart


==================Installing mod_wsgi ===========


sudo aptitude install libapache2-mod-wsgi


Restart Apache to get mod_wsgi to work.

sudo service apache2 restart


======================postgreSQL=====================
Postgres package and a "contrib" package that adds some additional utilities and functionality:

sudo apt-get install postgresql postgresql-contrib


Upon installation Postgres is set up to use "ident" authentication, meaning that it associates Postgres roles with a matching Unix/Linux system account

sudo -i -u postgres

You will be asked for your normal user password and then will be given a shell prompt for the postgres user.

You can get a Postgres prompt immediately by typing:

psql


create a database 

createdb test1


go out of this by \q


lets create a user and give them a password

first create a new user in linux

adduser test1		#this will prompt you for a password use 'test1' to keep things simple

log into psql

sudo -i -u test1
psql

at the prompt add a password for this user (no idea why tis has to be done again instead of useing the unix password)

ALTER ROLE test1 WITH PASSWORD 'test1';


---------------python bindings----------------------------

In addition to a database backend, you’ll need to make sure your Python database bindings are installed.

If you’re using PostgreSQL, you’ll need the postgresql_psycopg2 package


sudo apt-get install python-psycopg2


======install Django==============

make sure you install pip first
The python-dev and build-essential packages are recommended to install along, because it isn't possible to install any Python module that ships with a C extension without them later on.

sudo apt-get install python-pip python-dev build-essential && sudo pip install --upgrade pip

then

sudo pip install Django

==========make django project==============

create a folder 

mkdir /var/www/testsite.com

go into the folder and run

django-admin.py startproject testsite .   #note the full stop, it makes sure the django installer does not make another directory and place the install filed into it






==========HOSTING======================

Create your new virtual host node which should look something like this


sudo nano /etc/apache2/sites-available/mydomain.com.conf

put this



<VirtualHost *:80>
	ServerAdmin webmaster@mydomain.com
        ServerName testsite.com
        ServerAlias testsite.com

        WSGIScriptAlias / /var/www/testsite.com/index.wsgi

        Alias /static/ /var/www/testsite.com/static/
        <Location "/static/">
            Options -Indexes
        </Location>
</VirtualHost>



make the static directory

mkdir /var/www/testsite.com/static/

create the index.wsgi file (can be any name not just index)

vim /var/www/testsite.com/index.wsgi

add this to the file 

import os
import sys
sys.path.append('~/www/testsite.com/')
os.environ['DJANGO_SETTINGS_MODULE'] = 'testsite.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()



enable the site

 a2ensite /etc/apache2/sites-available/www.testsite.com.conf

sudo service apache2 restart

edit your Apache server’s httpd.conf file and add the following. If you are using a version of Apache older than 2.4, replace Require all granted with Allow from all and also add the line Order deny,allow above it.The first bit in the WSGIScriptAlias line is the base URL path you want to serve your application at (/ indicates the root url), and the second is the location of a “WSGI file” – see below – on your system, usually inside of your project package (mysite in this example). This tells Apache to serve any request below the given URL using the WSGI application defined in that file.

The WSGIPythonPath line ensures that your project package is available for import on the Python path; in other words, that import mysite works.

The <Directory> piece just ensures that Apache can access your wsgi.py file.
On Ubuntu the main Apache configuration file is actually apache2.conf



WSGIScriptAlias / /var/www/testsite.com/testsite/wsgi.py
WSGIPythonPath /var/www/testsite.com

<Directory /var/www/testsite.com>
<Files wsgi.py>
Require all granted
</Files>
</Directory>


sudo service apache2 restart

=====================CONFIGURE DJANGO APP================

Now, edit testsite/settings.py. It’s a normal Python module with module-level variables representing Django settings. add the postgresql details we created earlier NAME is the database name 

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'test1',
        'USER': 'test1',
        'PASSWORD': 'test1',
        'HOST': '127.0.0.1',
        'PORT': '5432',
    }
}


now create the default tables using the manage function

python manage.py migrate


==========dont forget to migrate static content============
Add to settings:

STATIC_URL = '/static/'
STATIC_ROOT = '/var/www/static/'

Then run "python manage.py collectstatic"

====================DJANGO APP==============================
