 定时重启mysql服务  原因是mysql服务超时 默认是8小时超时的 改为21小时 每天7点定时重启

解决方法：

 
mysql> show global variables like 'wait_timeout';
+----------------------------+-------+
| Variable_name              | Value |
+----------------------------+-------+
| wait_timeout               | 28800    |
+----------------------------+-------+
 

mysql> set global wait_timeout=90000;

+----------------------------+-------+
| Variable_name              | Value |
+----------------------------+-------+
| wait_timeout               | 90000|
+----------------------------+-------+


mysql>set global  interactive_timeout=90000;

+----------------------------+-------+
| Variable_name                      | Value |
+----------------------------+-------+
| interactive_timeout               | 90000|
+----------------------------+-------+

show global variables like '%_timeout';
