Unable to connect to any of the specified MySQL hosts为什么连不上mysql?

[lily_lucky]

<add name="MySql" connectionString="server=127.0.0.1:8080;user=root;password=123456;database=school)"/>
这是连接字符串

[james0210]

$con = mysql_connect("127.0.0.1:8080","root","123456");
$db_selected = mysql_select_db("school", $con);
