我安装WP是数据库出错，提示如下
Error establishing a database connectionThis either means that the username and password information in your
wp-config.php file is incorrect or we can't contact the database server at
localhost. This could mean your host's database server is down.
- Are you sure you have the correct username and password?
- Are you sure that you have typed the correct hostname?
- Are you sure that the database server is running?
If you're unsure what these terms mean you should probably contact your host. If you still need help you can always visit the
WordPress Support Forums.
数据库名称和密码应该没问题，请帮我看看服务器该填什么？谢谢
