Download, compile, make, and install mod_python
and mod_wsgi.
PS: mod_python shouldn’t be used. https://docs.python.org/2/howto/webservers.html
covers the history and the reasoning for doing so.
Cmds: (as a privileged user)
cd /tmp/;mkdir mod_python_3.5.0;cd mod_python_3.5.0/
wget http://dist.modpython.org/dist/mod_python-3.5.0.tgz
gunzip mod_python-3.5.0.tgz
tar -xvf mod_python-3.5.0.tar
cd mod_python-3.5.0/
[If you don’t have apxs (APache eXtenSion) then install
httpd development package]
yum install httpd-devel
./configure --with-python=/usr/local/bin/python2.7
[you can omit --with-python option if you want to use the
default

Install AWS tools and boto: Follow instructions on

.bashrc file: (you decide you want for all user for a
particular user. Pls note that for a particular user for boto they could have
.boto file under their home dir)

Accessing boto
within Apache
1.
Create a python virtual environment, install
boto
2.
Create /etc/boto file and copy the contents of
your boto file
3.
Configure Apache to use the virtual environment
WSGIScriptAlias
/myapp /var/www/wsgi-scripts/myapp.wsgi #mapping
WSGIPythonHome
/usr/local/lib/python2.7/site-packages/BASELINE #home of python virtual
environment
WSGIPythonPath
/var/www/wsgi-scripts #path to your python scripts
4.
(optional) redirect output from existing python
code so that phython module elsewhere needs minimal code change.
output =
cStringIO.StringIO()
sys.stdout =
stdout = cStringIO.StringIO()
#call to your
python code that uses boto for AWS
print >>
output, stdout.getvalue()
