Installing Drupal

Hello,

I have a problem with the Drupal 6 installation.

Settings:
Version Apache : Apache/2.2.22
Version MySQL : mysql Ver 14.14 Distrib 5.5.28
Version PHP 5.2.17

I try to install Drupal as usual (copy default.settings.php -> settings.php...).
Then I go to "http://localhost" with my browser to set up the installation.
But at the database configuration, when I confirm my settings, I have the HTTP 500 Internal server error.

It is possible to install Drupal 7 created in the database tables with collation others than utf8_general_ci? (specifically I needed utf8_czech_ci).
If so, where do I set this?
Thanks so much for the info

I copied a drupal 7.34 install over to a new server. The host required a prefix to my database and username, so I changed settings.php to reflect the new information. Upon visiting the website, I get a MYSql PDO exception where it's denying access to the old mysql username from the previous install. This is not the new username now in settings.php.

Hello. Can anyone help with Drupal install on a free server and connected database?

With regard to the excellent document Building a Drupal site with Git, I have several questions about how this translates to Drupal 8; so I'm posting each as a separate topic.

When following the best-practice outlined in Building a Drupal site with Git, one ends up with two git remotes: the drupal one with all the core code and your own, fooproject, encompassing drupal core along with your site adds. Both git trees are rooted in the same folder.

This is the command I hoped would install drush.
ksh -c "(composer global require drush/drush:dev-master 2>&1)" |tee go.log

the log of the messages is this.
