500 internal server error while installing What is the reason for the error "500 internal server error" while trying to install drupal,


i have created database successfully
After that i have downloaded and extracted the drupal 7.22 in my desired        directory.


But when i trying to install the tables in my database its showing  the error and approximately more than 30 tables are storing and the installation process stops automatically with showing the above error . Can anybody tell me why the error is coming.
As Clive says above, it's nearly impossible to help without knowing more about your particular setup and debug info.

Common pitfalls are :


Various php.ini settings : max_execution_time as mentioned by monymirza above, but also memory_limit. This last can be raised during install and dev, then lowered for production.
Lacking .htaccess at Drupal's root. Standard unix commands often don't copy hidden files, and .htaccess is more or less mandatory for D7 to work.
Lousy DB connection, particularly on shared hosting.
Misconfigured vhost : perhaps a particular setting messes up things between domains, or subdomains. Also, you have to check the AllowOverride All directive on Drupal directory for it to function properly.


There are others, but these should get you started.
