Apache HTTP Server

Modules

UserDir

UserDir module allows users on the server have a web site in their home directory.

Configuration

-Check if the module is available in the directory /etc/apache2/mods-available/

-Open the conf file, /etc/apache2/mods-available/userdir.conf. 

$ gksudo gedit /etc/apache2/mods-available/userdir.conf & 

<IfModule mod_userdir.c>
        UserDir public_html
        UserDir disabled root
        UserDir disabled
        UserDir enabled username

        <Directory /home/*/public_html>
                AllowOverride FileInfo AuthConfig Limit
#                Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec
                Options MultiViews SymLinksIfOwnerMatch IncludesNoExec
        </Directory>
</IfModule>

-To prevent the files and directories from being listed when there are no index files such as index.html, index.htm and so on, remove Indexes from the following line 

                Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec

So it would be like this 

                Options MultiViews SymLinksIfOwnerMatch IncludesNoExec

It is already commented out from the above example.


-Enable the module. 

$ cd cd /etc/apache2/mods-enabled/ 
$ sudo ln -s ../mods-available/userdir.load userdir.load 
$ sudo ln -s ../mods-available/userdir.conf userdir.conf

-Restart the Apache server 

$ sudo /etc/init.d/apache2 restart

-make a copy of the default virtual host configuration to have your own. 

$ sudo cp /etc/apache2/sites-available/default /etc/apache2/sites-available/mysite

Enable .htaccess

-Change AllowOverride None 

e.g)
	<Directory />
		Options FollowSymLinks
		AllowOverride None
	</Directory>

to 

	<Directory />
		Options FollowSymLinks
		AllowOverride All
	</Directory>


-make changes as you wish then disable the default one and enable yours. 

$ sudo a2dissite default && sudo a2ensite mysite


Using SSL

Generating a Certificate Signing Request (CSR)

Generate A Key for the CSR

-To generate the keys for the Certificate Signing Request (CSR) run the following command from a terminal prompt: 

$ openssl genrsa -des3 -out server.key 1024 

Generating RSA private key, 1024 bit long modulus
.......................++++++
.++++++
e is 65537 (0x10001)
Enter pass phrase for server.key:your passphrase
Verifying - Enter pass phrase for server.key:your confirm passphrase


-To See the details of the RSA private key. 

$ openssl rsa -noout -text -in server.key


Remove Passphrase from Key File

If there is a problem with starting apache when the computer is booted, remove passphrase from the key file can be used to solve it. -Make backup file first 

$ cp server.key server.key.original

-Remove the encryption from the RSA private key. 

$ openssl rsa -in server.key.original -out server.key

-Make sure the server.key file is only readable by root: 

$ chmod 400 server.key

Create the CSR

-To create the CSR, run the following command at a terminal prompt: 

$ openssl req -new -key server.key -out server.csr 

Enter pass phrase for server.key:your passphrase
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:Country
State or Province Name (full name) [Some-State]:State
Locality Name (eg, city) []:City
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Company
Organizational Unit Name (eg, section) []:Section
Common Name (eg, YOUR name) []:Your Name
