SQLSTATE [HY000]错误，当我尝试使用phpmyadmin在PDO中连接本地数据库时，无法连接到mysql服务器时发生错误

Question

我尝试使用PDO将页面与本地服务器中的phpmyadmin连接，但我无法连接至该页面，并且我收到SQLSTATE错误，有人可以通过它帮助我。

config.php:
<?Php
$dbhost_name = "localhost";
$database = "seekouttech";// database name
$username = "root"; // user name
$password = ""; // password 

//////// Do not Edit below /////////
try {
$dbo = new PDO('mysql:host=localhost;dbname='.$database, $username, $password);
} catch (PDOException $e) {
print "Error!: " . $e->getMessage() . "<br/>";
die();
}
?> 
pagination1.php

<meta http-equiv="X-UA-Compatible" content="IE=8" />

<?php include "./includes/menu_include.php";
$t=$_GET['id2'];
echo $t;
 $nws_id = $t;
?>
<?Php
include "config.php";           // All database details will be included here 
$page_name="pagination1.php"; 
$start=$_GET['start'];
if(strlen($start) > 0 and !is_numeric($start)){
echo "Data Error";
exit;
}


$eu = ($start - 0); 
$limit = 10;                                 // No of records to be shown per page.
$this1 = $eu + $limit; 
$back = $eu - $limit; 
$next = $eu + $limit; 



$query2=" SELECT * FROM comment where newsid='$t' ";
$count=$dbo->prepare($query2);
$count->execute();
$nume=$count->rowCount();
$query=" SELECT * FROM comment  limit $eu, $limit ";
foreach ($dbo->query($query) as $row) {

echo $row[name]; 
}
if($nume > $limit ){
if($back >=0) { 
print "<a href='$page_name?start=$back'><font face='Verdana' size='2'>PREV</font></a>"; 
} 

$i=0;
$l=1;
for($i=0;$i < $nume;$i=$i+$limit){
if($i <> $eu){
echo " <a href='$page_name?start=$i'><font face='Verdana' size='2'>$l</font></a> ";
}
$l=$l+1;
}

if($this1 < $nume) { 
print "<a href='$page_name?start=$next'><font face='Verdana' size='2'>NEXT</font></a>";}

这是我要实现分页的代码，我想使用mysql检索从数据库中获取的所有注释。

Answer 1

显而易见的答案是mysql没有运行。

请尝试在命令行上连接到mysql以确认它正在运行
