Protect files using .htaccess

Posted in Uncategorized, tagged access control, apache, authentication, authorization, htaccess, linux on March 22, 2010| 2 Comments »

Some times you may have some content that you want small group of people to view it in your application.

The Apache allows you to protect directories with the .htaccess and .htpasswd configuration files so any one request a file from it will prompet a box with username and password.

FIRST we need to make a password file (should be somewhere not accessible from the web ).

# htpasswd -c /home/.htpasswd demo (this will create the file in home directory)

and it will ask you for a password and confirmation

SECOND go to the folder that you want to protect Ex(/public_html/project/semsem)

create .htaccess file and place the following:

AuthUserFile /home/.htpasswd -password file

AuthName “restricted area” -description will appear in login screen

AuthType Basic

Require valid-user

and we are done , go to the required path and enter your credential.

note: you will need to AllowOverride directive

do this follow below steps.It will be using the same cherrypy,flup,demjson,pycurl which you have already downloaded

CherryPy for python2.5
======================
a. Go to the directory where you downloaded the cherrypy package.

# python2.5 setup.py install

check if it installed using.
# python2.5
# import cherrypy

Flup for python2.5

# unzip apache-ant-1.8.0-bin.zip

#export ANT_HOME=/usr/local/ant/apache-ant-1.8.0

=============

Prepare Environment
===================
craete directory -ParentDirectory- to hold DIMDIM source code
i called it <webinar>
create direcroty
# mkdir usr/local/Dependencies/Reflector/corona_fcgi_libs
copy libs to it
# cp usr/local/lib/*so* /usr/local/Dependencies/Reflector/corona_fcgi_libs

Create Direcroty tmp – as build dosn’t create it
# mkdir /usr/local/webinar/v4.1/WebApps/ServerII/tmp

# cd <webinar>/v4.1/FCGIApps/Reflector
# vi compile_all.sh
Specify corona and fcgi installed path like

# export FCGI_DIR=/usr/local/lib
# export CORONA_DIR=/usr/local/lib

Now make a directory structure above to v4.1 as shown below

<webinar>
—–v4.1
———-Dependencies
—————Reflector
——————-corona_fcgi_libs

Now do
# cp /usr/local/lib/*so* <ParentDirectory>Dependencies/Reflector/corona_fcgi_libs/

Now try to run Build script
# cd <ParentDirectory>/v4.1/Product/Build/Scripts/SF_RPM_Script/
# ant -f Dimdim_SF_32_v4.5_build.xml build

You can find RPM under RPMS/<architecture> directory
If you build on 32 bit machine, RPM will be under
/usr/src/redhat/RPMS/i386/dimdim-4.5-1.i386.rpm

If you build on 64 bit machine, RPM will be under
/usr/src/redhat/RPMS/x86_64/dimdim-4.5-1.x86_64.rpm

if you can’t find the RPM

go to this path :
/usr/local/webinar/v4.1/Product/Build/Scripts/SF_RPM_Script/Helper/
and run Dimdim-4.5.sh
# ./Dimdim-4.5.sh

Note:
=====
1-you have to remove this folders:
webinar
/BUILD files

2-stop apache service running on port 80….
# service httpd stop

3-Skip OS check
Dimdim-4.5 require CentOS 5.2 … if you want to install it on CentOS 5.3 then have to skip OS check ?
There is a file which check OS “/etc/issue”
# vi /etc/issue
here replace CentOS release 5.3 (Final) to CentOS release 5.2 (Final)

you can run the rmp
#rpm -ivh file.rpm

now go to:
# cd /usr/local/dimdim
# ./Config-ipaddress.pl 123.X.X.X 85

changed IP to XXX.X.X.X and port to 80

and start you dimdim server using
# ./StartDimdim.sh

here now you have your webinar working

FINAL
=====

check this bash file
as there is some variable need to be set so all feature run probably

FINAL (.bash_profile )
======================

#PATH=$PATH:$HOME/bin
#JAVA_HOME=/usr/java/jre1.6.0_18
#export JAVA_HOME

#PATH=$JAVA_HOME/bin:$PATH:$HOME/bin:/usr/local/bin
#export PATH

#LD_LIBRARY_PATH=/usr/local/lib:/usr/lib64:/opt/openoffice.org/basis3.0/program
#export LD_LIBRARY_PATH

#unset USERNAME
