Setting up django: step 1, python 2.7.1

Just trying out some django in centos 5.5. So this should not been seen as a good solution. Just me trying to set it up properly

some pre preps

yum -y groupinstall 'Development Tools'

yum -y install openssl-devel* zlib*.x86_64

yum -y install httpd-devel

yum -y install mysql-devel

yum -y install wget

downloaded and untarred 2.7.1

cd /usr/local/src

wget http://www.python.org/ftp/python/2.7.1/Python-2.7.1.tgz

tar -xzvf Python-2.7.1.tgz

compiled it with embedded so we can use apache mod wsgi. Used a seperate path so that it is not conflicting with the internal python

./configure --prefix=/opt/python2.7 --with-threads --enable-shared

make

make install

added the new library to the dynamic loader

echo "/opt/python2.7/lib" > /etc/ld.so.conf.d/python27.conf

ldconfig

We can now test it

[root@django ld.so.conf.d]# /opt/python2.7/bin/python

Installing the setup tools

cd /usr/local/src

wget http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg

Installing the mysql bindings

cd /usr/local/src

wget http://downloads.sourceforge.net/project/mysql-python/mysql-python/1.2.3/MySQL-python-1.2.3.tar.gz?r=&ts=1299013136&use_mirror=netcologne

tar -xzvf MySQL-python-1.2.3.tar.gz

python2.7 setup.py build

python2.7 setup.py install

Installing wsgi

cd /usr/local/src

wget http://modwsgi.googlecode.com/files/mod_wsgi-3.3.tar.gz

./configure --enable-shared --prefix=/opt/mod_wsgi-3.3 --with-python=/opt/python2.7/bin/python

make

make install

A mod should be made. You can find it in

Libraries have been installed in:

/usr/lib64/httpd/modules

The mod itself:

/usr/lib64/httpd/modules/mod_wsgi.so

echo "LoadModule wsgi_module /usr/lib64/httpd/modules/mod_wsgi.so" > /etc/httpd/conf.d/wsgi.conf

echo "AddHandler wsgi-script .wsgi" >> /etc/httpd/conf.d/wsgi.conf

chmod 755 /etc/httpd/conf.d/wsgi.conf

/etc/init.d/httpd restart

Installing django

wget http://www.djangoproject.com/download/1.2.5/tarball/

python2.7 setup.py install

cd /tmp

cat <<> test.py

#!/opt/python2.7/bin/python

import django

print django.get_version()

EOF

chmod +x test.py

[root@django html]# ./test.py

1.2.5

Symlinking the django admin so we can use it everywhere

ln -s /opt/python2.7/bin/django-admin.py /usr/local/bin/django-admin.py

Configuring apache to use django

cat <<> /etc/httpd/conf.d/django.conf

WSGIScriptAlias / /var/www/django/django.wsgi

Order allow,deny

Allow from all

EOF

creating the django handler

mkdir -p /var/www/django

cat <<> /var/www/django/django.wsgi

import os

import sys

path = '/var/www/django'

if path not in sys.path:

sys.path.append(path)

os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'

import django.core.handlers.wsgi

application = django.core.handlers.wsgi.WSGIHandler()

EOF

chmod 755 /var/www/django/django.wsgi

Now we can create a site

cd /var/www/django/

django-admin.py startproject mysite

Restart the webserver to activate everything

/etc/init.d/httpd restart
