1. 升级python到2.5.2:
用Putty登录到DreamHost的Shell控制台执行如下的命令:

mkdir opt
cd opt
mkdir packages
cd packages
wget http://www.python.org/ftp/python/2.5.2/Python-2.5.2.tgz
tar -xzvf Python-2.5.2.tgz
cd Python-2.5.2
./configure -prefix=$HOME/opt
make
make install

python 2.5已经安装好了。把python 2.5设置为默认版本：

vim ~/.bash_profile

然后，在~/.bash_profile里加入一条：

export PATH=$HOME/opt/bin/:$PATH

重新载入配置文件：

source ~/.bash_profile

检验一下是否成功：

$python -V
Python 2.5.2

2. 安装python-Mysql

cd ~/opt/packages
wget http://internap.dl.sourceforge.net/sourceforge/mysql-python/MySQL-python-1.2.2.tar.gz
tar xvzf MySQL-python-1.2.2.tar.gz
cd MySQL-python-1.2.2
python setup.py install

3. 安装django

cd ~/opt/packages
wget http://www.djangoproject.com/download/1.0/tarball/
tar -xzvf Django-1.0.tar.gz
cd Django-1.0
python setup.py install

在python交互环境下查看django的版本，以测试安装配置的准确性。

$python
>>>import django
>>>django.VERSION
(1, 0, 'final')

4. 创建Django项目

mkdir ~/django_projects
cd ~/django_projects
django-admin.py startproject myproject
chmod 600 myproject/settings.py

vim myproject/settings.py :

DATABASE_ENGINE = 'mysql' [...]
