' host: 'localhost' (Got timeout reading communication packets)

解决办法：
修改[root@lovebuy114 ~]# grep timeout /etc/my.cnf
interactive_timeout = 120
wait_timeout = 120
log_warnings=1 //注意，我这里原来是2。修改成1后，问题现象果然但是已经不存在了。
在命令行中可以这样修改：
mysql>set global log_warning=1;
mysql>set global interactive_timeout = 120;
mysql>set global wait_timeout = 120;
参数简要说明：
1)interactive_timeout:
参数含义：服务器关闭交互式连接前等待活动的秒数。交互式客户端定义为在mysql_real_connect()中使用CLIENT_INTERACTIVE选项的客户端。
参数默认值：28800秒（8小时）

解决无Notice的办法：

grep timeout /etc/my.cnf     innodb_lock_wait_timeout = 60
interactive_timeout = 28800
wait_timeout = 22
grep log_warnings /etc/my.cnflog_warnings=2

修改后，无效，原因是现在是变成了Notice，不是警告：
