在 wordpress 上建立数据库连接时出错

Question

运行 WordPress 项目时出现此错误：

Error establishing a database connection This 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 %s. This could 
mean your host's database server is down.

我该如何解决这个错误？ 请帮忙。 提前致谢。
