mysql同步error（Slave_IO_Running: Connecting）

我的mysql版本：
[root@cancer ~]# rpm -qa|grep My
MySQL-shared-5.5.11-1.linux2.6
MySQL-devel-5.5.11-1.linux2.6
MySQL-embedded-5.5.11-1.linux2.6
MySQL-test-5.5.11-1.linux2.6
MySQL-server-5.5.11-1.linux2.6
MySQL-client-5.5.11-1.linux2.6
MySQL-shared-compat-5.5.11-1.linux2.6
[root@cancer ~]#
同步设置：主服务器：172.16.20.1 从服务器：172.16.20.2
1.主服务器上创建同步账户，修改my.cnf;重启，锁表，mysqldump导出数据库destoon；
2.从服务器上导入数据源destoon，修改my.cnf，重启mysql，登录change master...加入主服务器信息，slave start之后，show slave status\G;显示信息如下：
mysql> show slave status\G;

重新reset slave，在加入master信息还是不行；
这时主服务执行
mysql> show processlist;
+----+------+-----------+------+---------+------+-------+------------------+

1 row in set (0.00 sec)
从服务器显示：
mysql> show processlist;

| 23 | system user | | NULL | Connect | 513 | Slave has read all relay log; waiting for the slave I/O thread to update it | NULL |
+----+-------------+-----------+-------+---------+------+-----------------------------------------------------------------------------+------------------+

从服务器log：

哎呀，我实在不知道怎么做了，已经搞了一周了各位大侠帮我看看，分送上
