13. Sudo service apache2 restart
14. Access: http: // 127.0.0.1/py/pytest. py

Iv. virtualenv installation and configuration

1. Sudo apt-get install-y python-dev python-setuptools
2. Sudo easy_install virtualenv virtualenvwrapper pip
3.  
4. Sudo mkdir/home/dave/study/webapps // The total working directory of all virtualenv Environments
5. Sudo chown-R www-data: www-data/home/dave/study/webapps
6. Sudo chmod-R g + rw/home/dave/study/webapps
7.  
8. Add the following line ~ /. Bashrc:
9. Export VIRTUALENV_USE_DISTRIBUTE = 1
10. Export WORKON_HOME =/home/dave/study/webapps
11. Source/usr/local/bin/virtualenvwrapper. sh
12. Export PIP_VIRTUALENV_BASE = $ WORKON_HOME
13. Export PIP_RESPECT_VIRTUALENV = true
14. Export PYTHONPATH =/usr/local/lib/python2.7: $ PYTHONPATH
15.  
16. Then source ~ /. Bashrc. If an error is reported, view the directory owner and permissions.

Create a virtual environment and install related software:

1. Cd ~ /Study/webapps
2. Mkvirtualenv firstenv
3. Pip install "django = 1.4.5 ",
4. Pip install MySQL-python
5. // Install the related software in the virtual environment. Note that before installing mysql-python, you must first install sudo apt-get install python-dev libmysqlclient-dev; otherwise, the installation will fail.
6.  
7.  
8. Check whether django is successfully installed:
9. Python, enter idle
10. > Import django
11. > Print django. VERSION
12. 1.4.5

For general usage of virtualenvwrapper, see http://www.cnblogs.com/Phenix_Yang/archive/2012/05/08/2489724.html:

1. Cd webapps
2. Mkvirtualenv NAME // create a virtual environment
3. Rmvirtualenv NAME // delete a virtual environment
4. Lsvirtualenv // list all Virtual Environments
5. Workon NAME // enter the specified virtual environment. If no NAME is specified, all virtual environments are listed.
6. Deactivate // exit the current Virtual Environment

General Usage of pip: when installing the software, pip is found on the pypi website, while pypi only collects links to the software package. The problem is that the link may be invalid, so pip is also flawed.

1. Pip freeze // list all installed software packages
2. Pip search django // find the software package with django in the name
3. Pip install django // install django. The latest version is installed by default.
4. Pip install "django = 1.4.5" // specify the version when installing the software package. You can also use <, <=,>,> = to specify the version range, for example, pip install "django> 1.4 <1.5"
5. Pip install-U django // upgrade django
6. Pip uninstall django // uninstall django
