hibernate被拒绝连接非默认的mysql端口

时间：2012-04-15 05:43:27

标签： java mysql spring hibernate

我在默认的3306端口从Linux连接MySQL（5.1.6）数据库，一切都很好：

<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/wpdb" />
<property name="username" value="root" />
<property name="password" value="" />

现在，我进入/etc/mysql/my.cnf并将默认端口更改为3307（[client]和[mysqld]）重启MySQL，调整hibernate连接url：

<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3307/wpdb" />
<property name="username" value="root" />
<property name="password" value="" />

然后重启jboss。这次我无法连接：

知道mysql拒绝连接的原因是什么？没有其他配置被更改..但MySQL默认端口。没有防火墙启动并运行。

感谢您的任何建议。

2 个答案:

答案 0 :(得分：1)

首先，您可以检查可以运行的服务器中使用的选项：

   mysqld --verbose --help

停止服务

  sudo service mysql stop

应该更改的选项是[mysqld]部分中的port，正如你之前在/etc/mysql/my.cnf上所说的那样，但要确保文件＆＃34;〜/ .my.cnf＆＃ 34; （如果存在）不会覆盖端口。无论如何，想法是设置端口，如下所示：

   port            = 3307

最后再次启动MySQL服务，当然还有JBoss。

   sudo service mysql start

使用mysqld --verbose --help检查端口，看看是否所有内容都符合您的预期。

另一方面，您可以使用某个客户端应用程序和相同的连接器jar测试连接。即：SQuirrel，并在相应的lib目录中处理库。当我遇到这样的问题时，这真的很有帮助。

我希望这会有所帮助。

答案 1 :(得分：1)

我也面临同样的问题。更改另一个版本的jdbc mysql驱动程序。因为当我使用mysql 5.1.9驱动程序时它会引发连接拒绝（成功发送到服务器的最后一个数据包是0毫秒前。驱动程序没有从服务器收到任何数据包。）问题然后我切换了另一个版本，如5.1.18它可以工作。
