php连接mysql 错误提示:由于目标计算机积极拒绝,无法连接
用命令提示符操作mysql是没有问题的,包括查询插入更新都没有问题。
php.ini配置如下:;extension=php_mysql.dll
;extension=php_mysqli.dll
前面的分号都去掉了呀。
错误提示如下:
Warning: mysql_connect() [function.mysql-connect]: [2002] 由于目标计算机积极拒绝,无法连接。 (trying to connect via tcp://localhost:3306) in F:\Apache\htdocs\ch13\13-1.php on line 6
Warning: mysql_connect() [function.mysql-connect]: 由于目标计算机积极拒绝,无法连接。 in F:\Apache\htdocs\ch13\13-1.php on line 6
数据库连接失败:
由于目标计算机积极拒绝,无法连接。
php代码如下:
<?php$host='localhost';$user_name='root';$password='admin';$conn = mysql_connect($host,$user_name,$password);if(!$conn){ die('数据库连接失败:<br/>'.mysql_error());}echo '数据库连接成功!';?>
回复讨论(解决方案)
请各位大侠相助,不胜感激
呵呵。。没权限访问吧,你把数据库设置一下
然后用户名密码确定能这样对$user_name='root';
$password='admin';
用户权限的问题,你看看你的 命令提示符操作时是不是没有user数据库啊
估计还是php.ini文件的配置有不对的地方。
这个说明你连接目标机器后,他的系统自动视为是攻击对象了,
你把他的防火墙关了试试
估计是防火墙阻挡了

检查一下用户名和密码是否正确,再检查一下防火墙是否禁止了MYSQL的默认端口
把防火墙关了,在试试,个人经验觉得是防火墙的问题,应该是3306端口被拒绝了

是没有user数据库,该如何设置呢?
我的也没有USER数据库都可以正常连接。
show database显示:几个数据库;
其中没有user数据库,但是在mysql数据库下有一个user表。
防火墙关闭后提示错误依然如旧,我安装的是360安全卫士和360杀毒,这个卸载再试试?

是PHP5.3吗?如果是的话,估计是你的数据库连接服务器名设置是localhost,改为127.0.0.1即可,
试一下,因为PHP5.3以后不支持直接以localhost进行连接
还有这样的问题啊,从来没碰到过,按它提示的信息应该是防火墙的问题,既然关了都不行,真不知道了,你telnet 127.0.0.1 3306看看能不能登陆上。可能是数据库版本的问题
遇到相同的问题,请高手详细指导,谢谢!
我也遇到过同样的问题,我在程序中加上端口号就行了。
$conn=mysql_connect("127.0.0.1:3307","root","root") or die (mysql_error());
if(!$conn) echo "Failed!";
else echo "Successful!";
print_r ($conn);
mysql_close();
?>
