Fully qualified domain name error

While restarting the apache server, we may get 'Your server does not have a fully qualified domain name.' To solve this problem, we go to httpd.conf file.

/etc/apache2/httpd.conf

Add the domain name that is pointed to this IP address.

ServerName localhost

Then restart the apache web server.

sudo /etc/init.d/apache2 restart

Sample Virtual Host File

We use virtual hosts for our web sites. I have added a sample virtual hosts here. I have removed indexes option, so none can't browse folders if there is no index file. Also disabled MultiViews option. I have renamed the .htaccess file name to myobscurefilename and controlled limited access to it.

  # Admin email, Server Name (domain name) and any aliases
  ServerAdmin test@domain.com
  ServerName  www.domain.com
  ServerAlias domain.com


  # Index file and Document Root (where the public files are located)
  DirectoryIndex index.php index.html
  DocumentRoot /home/test/public_html/domain.com/public

  
   Options FollowSymLinks -Indexes -MultiViews
   AllowOverride All
  
  
  AccessFileName .myobscurefilename
  
    Order allow,deny
    Deny from all
    Satisfy All
  

  # Custom log file locations
  LogLevel warn
  ErrorLog  /home/test/public_html/domain.com/logs/error.log
  CustomLog /home/test/public_html/domain.com/logs/access.log combined

why use virtual hosts?

We use virtual hosts for our websites. Why we use them? Let's discuss it here with bullet points(I don't like theoritical talking).
1. Virtual hosts enables us to use same machine, same resources for multiple applications. Each application acts like its running on its own hosting server.
2. The sessions and cookies are stored against their own domain name set on the virtual hosts.

Enable Tab to pre-populate file name in vim

If you create a new user account in linux, then pressing Tab won't bring a filename with it's initials. To enable Tab you need to edit the passed file. Let's see how we can do it. 1. Create a user with:

useradd -d /home/testuser -m testuser

Here -d takes the user directory path and -m creates the user directory. you can use -p to set a password in the command. 2. To set a password use:

passed testuser

Then enter your password and retype it. 3. Now if you go to /home/testuser directory you will see .bashrc and .profile files. .bashrc file is used whenever a new tab opened in the console and .profile is used only for the first time while an authentication is done. Now we will change the /etc/passwd file. open the file and you will see your newly created user is listed there. There is sh beside his name. Change it to bash, like the following:

testuser:x:1003:1004::/home/testuser:/bin/bash

Now you will see that Tab is working in your console under your new user.
