Installing django, nginx and uwsgi on Ubuntu

Installing nginx and uwsgi

sudo su -
nginx=stable # use nginx=development for latest development version

apt-get install python-software-properties
add-apt-repository ppa:nginx/$nginx
add-apt-repository ppa:uwsgi/release

apt-get update
apt-get install nginx uwsgi python-virtualenv

Make a virtual environment. Ex.

virtualenv /home/jason/virtualenv

Activate the virtualenv ex.

source /home/jason/virtualenv/bin/activate

Install django

pip install django

Create django project ex.

django-admin.py startproject /home/jason/virtualenv/djangoprojecthome

Deploy nginx

Edit /etc/nginx/sites-available/default

ex.

upstream django {

# server unix:/var/run/uwsgi/uwsgi-python2.6/pinax/socket;

server 127.0.0.1:4000;

}

server {

listen 80;

server_name django.jasonwang.us;

location / {

uwsgi_pass django;

include uwsgi_params;

uwsgi_param UWSGI_PYHOME /home/jason/virtualenv;

uwsgi_param UWSGI_SCRIPT deploy; #the name of deploy.py

# uwsgi_param SCRIPT_NAME django;

uwsgi_param UWSGI_CHDIR /home/jason/virtualenv/djangoprojecthome;

}

location ^~ /media/ {

root /home/jason/virtualenv/djangoprojecthome/static;

}

}

ln -s /etc/nginx/sites-available/default /etc/nginx/sites-enabled/default

Edit /etc/uwsgi/uwsgi-python2.6/default.ini

I use vhost in my xml for virtual hosting to run multiple sites.

[uwsgi]

socket = 127.0.0.1:4000

master = true

processes = 4

vhost = true

no-site = true

Create a django wsgi file in your django project file. ex. /home/jason/virtualenv/djangoprojecthome/deploy.py

# pinax.wsgi is configured to live in projects/pine/deploy.

# from pinax

import os

import sys

from os.path import abspath, dirname, join

from site import addsitedir

addsitedir('/home/jason/virtualenv/lib/python2.6/site-packages')

sys.path.insert(0, abspath(join(dirname(__file__), "../")))

from django.conf import settings

os.environ["DJANGO_SETTINGS_MODULE"] = "djangoprojecthome.settings"

# sys.path.insert(0, join(settings.PROJECT_ROOT, "apps"))

from django.core.handlers.wsgi import WSGIHandler

application = WSGIHandler()

Restart nginx and uwsgi

sudo /etc/init.d/uwsgi-python2.6 restart

sudo /etc/init.d/nginx restart

SETTING UP DJANGO FROM SCRATCH ON AMAZON EC2

• Download putty with keygen
• download the pem key
• put pem through the putty keygen and save it as ppk
• find ami micro instances from here http://uec-images.ubuntu.com/releases/10.10/release/
• login to amazon ec2 interface and run that instance
• setup security group and open up port 22, 80
• login to server with putty and the key file
• "sudo aptitude update && sudo aptitude upgrade"
• run "sudo aptitude install python-virtualenv"
• "sudo aptitude install libc6 libgeoip1 libpcre3 libssl0.9.8 zlib1g lsb-base"
• "sudo aptitude install ec2-api-tools"

sudo aptitude install postgresql-8.4

# adduser databaseuser
# passwd databaseuser

sudo su postgres -c psql template1
template1=# ALTER USER postgres WITH PASSWORD 'password';
template1=# \q

sudo passwd postgres

sudo nano /etc/postgresql/8.3/main/postgresql.conf

Change the line containing

data_directory = '/var/lib/postgresql/8.3/main'

to

data_directory = '/data/main'

Now change

#listen_addresses = 'localhost'

to

listen_addresses = '*'

and also change

#password_encryption = on

to

password_encryption = on

Save the file, then open the pg_hba.conf file so we can control who can access the server:

# DO NOT DISABLE!
# If you change this first entry you will need to make sure that the
# database
# super user can access the database using some other method.
# Noninteractive
# access to all databases is required during automatic maintenance
# (autovacuum, daily cronjob, replication, and similar tasks).
#
# Database administrative login by UNIX sockets
local all postgres ident sameuser
# TYPE DATABASE USER CIDR-ADDRESS METHOD

# "local" is for Unix domain socket connections only
local all all md5
# IPv4 local connections:
host all all 127.0.0.1/32 md5
# IPv6 local connections:
host all all ::1/128 md5

# Connections for all PCs on the subnet
#
# TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD
host all all 0.0.0.0/0 md5 # wide-open, you may want to make this more specific to your database

start sql server

#create sql user

sudo su postgres

psql

CREATE USER 'user';

CREATE DATABASE 'database';

template1=# CREATE USER tom WITH PASSWORD 'myPassword';

Step #5: Add a database called jerry

Type the following command (you need to type command highlighted with red color):
template1=# CREATE DATABASE jerry;
Now grant all privileges on database
template1=# GRANT ALL PRIVILEGES ON DATABASE jerry to tom;
Type \q to quit:
template1=# \q

$ psql template1
OR
$ psql -d template1 -U postgres

replace %site with your site folder

the nginx site config files are in /etc/nginx/sites-available and ln -s to /etc/nginx/sites-enabled

In /etc/uwsgi/uwsgi-python2.6/ place your %site.ini file
