To protect a directory with .htaccess in Fedora

A folder or directory of the public documents can be protected to prevent unauthorized visitors from seeing its contents using "HTTP authentication"

Create a file named .htaccess in the directory you want to protect and put following into file:

AuthType Basic
AuthName "Secure Area"
AuthUserFile /etc/httpd/conf/htpasswdfile
Require valid-user

Save the file and exit.
Now create the htpasswd file at given location.

cd /etc/httpd/conf

htpasswd -c htpasswdfile admin

Here one user 'admin' and password file 'htpasswdfile' is being created with the command 'htpasswd'
It will prompt for password (2 times), supply the password.

## (Some how apache, the web server user is not able to read the password file if you place the file in /root and /home/ folder so keep the file in the location where the httpd.conf file is)

## Make sure AllowOverride is set to All in the httpd.conf file

Amazon EC2 Server Setup

Assuming you already created account on AWS ans S3 so you will be having:
EC2 Private Key
EC2 Certificate Key
User ID
S3 access key
S3 secret key

Download Amazon EC2 API Tools from here:

The command line tools used here require Java version 5 or later to run. Either a JRE or JDK installation is acceptable.

Unzip it at some location.
Let say on /root/amazon
Also assuming you have your EC2 Private Key & EC2 Certificate Key at /root/amazon/ec2

Set these in your environment. Open .bash_profile file and add these entries as below:


export PATH

export JAVA_HOME

export EC2_HOME


export EC2_CERT

After closing the .bash_profile file run the following command:
source .bash_profile

Finding a Suitable AMI:
ec2-describe-images -o self -o amazon | grep machine
ec2-describe-images | grep public

Generating a Keypair:
ec2-add-keypair gsg-keypair
Save the output content in a file (ex: id_rsa-gsg-keypair)

chmod 600 id_rsa_gsg-keypair

ec2-run-instances ami-86e90eef -k id_rsa_gsg-keypair
Note down the instance id (i-56a32e3f). This may be different for you.

ec2-describe-instances i-56a32e3f

(Note the Public URL ec2-174-129-185-64.compute-1.amazonaws.com, this may be different for you)

Authorizing Network Access to Your Instances:
ec2-authorize default -p 22
ec2-authorize default -p 80

Connecting to your Instance:

ssh -i id_rsa_gsg-keypair root@ec2-174-129-107-244.compute-1.amazonaws.com

root@my-instance #
After login to the ec2 server start the services
Start the Apache Web Server:
[root@ip-xx-xxx-xx-xxx:~] /etc/init.d/httpd start
Start the MySQl Server
[root@ip-xx-xxx-xx-xxx:~] /etc/init.d/mysqld start
Start the Asterisk Server
[root@ip-xx-xxx-xx-xxx:~] amportal start
