1:问题描述:
MySQL连接超时Communications link failure
2:问题分析:
因为MySQL默认的空闲等待时间是8个小时,一旦空闲超过8个小时,就会抛出异常。
3:解决方案:
3.1:编辑/etc/my.cnf(windows下为my.ini),将超时时间设置为10年,在[mysqld]后面加入:
wait_timeout=315360000
wait_timeout=315360000
interactive_timeout=31536000
在服务中重启mysql服务
3.2:在连接URL上添加参数:&autoReconnect=true&failOverReadOnly=false
