关于mysql数据库连接问题

'zabbix' failed: [1045] Access denied for user 'zabbix'@'localhost' (using password: YES)

这里提示是你的密码没有设置成功，所以你用zabbix用户登录时会报错
mysql> grant all on zabbic.* to 'zabbix'@'localhost' identified by '123456';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
[root@localhost wwwroot]# mysql -u zabbix -p123456

mysql>

这个就成功了。
后面的你可以把你的sql文件贴出来，报的都是sql文件的错。

如果报错的话把错误贴出来，还有就是你倒没倒连接jar包,3个jar加在程序里了吗？
import java.sql.*;
Connection conn =null;
try {
Class.forName("com.mysql.jdbc.Driver");
conn=DriverManager.getConnection("jdbc:mysql://localhost/mybbs", "root", "root");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
这样可以么？
