permission issue

name = os.popen('whoami').read()
print "the usr of the cgi is :"+name

cgi-bin

vim /etc/apache2/sites-enabled/000-default

        ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
        <Directory "/usr/lib/cgi-bin">
                AllowOverride None
                Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
                Order allow,deny
                Allow from all
        </Directory>

then I can put s.py into /usr/lib/cgi-bin/, can call it like this

<form method=POST action="cgi-bin/s.py">

error log

I got lots of errors, which are availbale to check at

/var/log/apache2/error-log

s.py

but finally this works

#!/usr/bin/python
import cgi
form = cgi.FieldStorage()

print "Content-type: text/html"
html ="""
<hr>
<p>%s</p>
<hr>
"""
print html % ("hello, %s"%form['user'].value)
