Create VirtualHost in Ubuntu

Hi All

Here is the Procedure to Create the VirtualHost in Ubuntu.

1. Create the folders that will host your new site. By default, Apache in Ubuntu serves from /var/www. So create this:

mkdir /var/www/site1

2.Copy the current default setting found in /etc/apache2/sites-available/default and name it the same as your new site.

cp /etc/apache2/sites-available/default /etc/apache2/sites-available/site1

3. Edit the new config files for each site using your preferred text editor. Add the line ServerName server1 right below the ServerAdmin line and change both DocumentRoot and Directory to point to your new site.

File:/etc/apache2/sites-available/site1

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    ServerName site1

    DocumentRoot /var/www/site1
    <Directory />
        Options FollowSymLinks
        AllowOverride All
    </Directory>
    <Directory /var/www/site1/>
        Options -Indexes FollowSymLinks MultiViews
        AllowOverride All
        Order allow,deny
        allow from all
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log

    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel warn

    CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

4. After you have edited the config file, just tell Apache to start serving the new domains

sudo a2ensite site1

5. Add the entry in your hosts file for new site.

file: /etc/hosts

127.0.0.1       site1

6. Now reload apache and you should be able to get new domain:

sudo /etc/init.d/apache2 reload

check the URL:- http://site1.

Note:-

If you have the .htacess files in your project and if you face any problems like NotFound and Internal Server Error Make sure rewrite Module available in "/etc/apache2/mods-enabled" if not please create the Symlink to the rewrite module, here is the code.

ln -s ../mods-available/rewrite.load rewrite.load

How to login as root from GUI in Fedora14

Hi Friends,

In Fedora14 I am posting solution for root lovers who like to login with root. Fedora 14 root login is exactly same like Fedora 12 root login.

WARNING :- Its not at all good to login as root from GUI. It’ DANGEROUS. BUT if some one wants to know that how to login as a root from GUI then follow the instructions.

In Fedora 14 You cannot login as a root from gui. By Default, only Normal users are allowed to login from gui mode.

I Managed to Login as a root from GUI on Fedora 14. Follow these steps and you will able to Login as a root from GUI on Fedora 14

If You want to login as a root from GUI in Fedora 14 then you have to edit something like some files which are located to /etc/pam.d/

Open your Te rminal from Applications -> System Tools -> Terminal

Now Login as a root from your terminal

Step 1 :- [user1@localhost]$ su – root
Password:-

Step 2:- Now go to your /etc/pam.d/ directory.

[root@localhost]# cd /etc/pam.d/

Then first take a backup of gdm file

cp gdm gdm.bkp ( always take backup if anything goes wrong you can correct it by original file)

Step 3 :- Now Open gdm file in your favourite editor. I am using vi as my editor.

[root@localhost pam.d]# vi gdm

Find and Comment or remove this line into your gdm file
auth required pam_succeed_if.so user != root quiet

Step 4 :- Save & Exit From that File. ( In Fedora10 Till step 4 is enought to Login as a root from GUI but for Fedora 13 you need one more file to edit otherwise you cannot Login as a root even though you edited gdm file).

Step 5 :- Here is the additional file that you need to edit and that file name is gdm-password. Open gdm-password file in your favourite editor. I am using vi as my editor.

Then first take a backup of gdm-password file

cp gdm-password gdm-password.bkp ( always take backup if anything goes wrong you can correct it by original file)

[root@localhost pam.d]#vi gdm-password

Find and Comment or remove this line into your gdm file
auth required pam_succeed_if.so user != root quiet


Step 6 :- Save & Exit from File. Now Logout and Try to Login as a root user. Now you are able to Login as a root user from GUI in Fedora 14.
