建立数据库连接时出错

This either means that the username and password information in your wp-config.php file is incorrect or that contact with the database server at db could not be established. This could mean your host’s database server is down.

您确定用户名和密码正确吗？
您确定输入的主机名正确吗？
您确定数据库服务器在运行吗？

If you are unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums.
