After installation how can i upload moodle on server,and use it as e-learning website online.
Your question doesn't make any sense...
You need to install Moodle on the server. If you have already installed it on (say) your desktop and now want to move the site to a proper server read Moodle_migration. However, if you have only created a small number of courses I would do a clean install on the server and use Course backup and restore.
