How To Solve 500 Internal Server Error When Install Magento

If you are installing Magento directly on your server, then you may get some errors while opening the installation wizard on your browser, i.e, 500 INTERNAL SERVER ERROR. Its mainly because of the wrong FILE PERMISSIONS.
The best way to solve this issue is here,

1. Download Magento Cleanup Tool
2. Unzip magento-cleanup.php to the root directory where Magento is installed.
3. Browse to http://yourdomain.com/magento/magento-cleanup.php

magento-cleanup.php source code

isDir() ) chmod( $path, $dirModes );
      else if( is_file( $path ) ) chmod( $path, $fileModes );
  }
}

## Function to clean out the contents of specified directory

function cleandir($dir) {

    if ($handle = opendir($dir)) {
        while (false !== ($file = readdir($handle))) {
            if ($file != '.' && $file != '..' && is_file($dir.'/'.$file)) {
                if (unlink($dir.'/'.$file)) { }
                else { echo $dir . '/' . $file . ' (file) NOT deleted!
'; } } else if ($file != '.' && $file != '..' && is_dir($dir.'/'.$file)) { cleandir($dir.'/'.$file); if (rmdir($dir.'/'.$file)) { } else { echo $dir . '/' . $file . ' (directory) NOT deleted!
'; } } } closedir($handle); } } function isDirEmpty($dir){ return (($files = @scandir($dir)) && count($files) <= 2); } echo "----------------------- CLEANUP START -------------------------
