Can't connect to MySQL server on '' (10060)
远程连接服务器出现以上错误
主要有三个原因：
1、mysql授权表里没有远程机器的权限，及需要在授权表mysql.user添加
grant all privileges on *.* to 'root'@'远程登陆IP' identified by '远程登陆密码'
flush privileges;
2、网络不通，这个就不说了。
3、防火墙禁止3306端口，以iptable为例
vi /etc/sysconfig/iptables
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 3306-j ACCEPT
service iptables restart
ps: iptables设置
1) 重启后生效
开启： chkconfig iptables on
关闭： chkconfig iptables off
2) 即时生效，重启后失效
开启： service iptables start
关闭： service iptables stop

If you set it in the cnf(it may be my.ini file) you will likely need to restart the server. Optionally, that is a dynamic variable and can be SET GLOBAL or SET SESSION from the command line as well.So just do as follows.
mysql>show variables like’max_allowed_packet’;
