wait_timeout参数控制非交互模式连接的超时时间(单位秒,默认值为24小时即86400秒),当非交互式连接空闲时间超过wait_timeout指定的时间后,RDS实例会主动关闭连接。 对于交互模式连接:通过 mysql 客户端 与 mysql server 建立的连接是交互式连接,interactive_timeout参数控制交互模式连接的超时时间(单位秒,默认值为2小时...
可以通过修改MySQL服务器的配置文件来增加wait_timeout的值,以延长连接的超时时间。找到MySQL配置文件(通常是my.cnf或my.ini),在文件中找到wait_timeout的配置项,将其值设定为较大的数值,例如86400(即24小时)。修改完成后,重启MySQL服务器使配置生效。 4.2 在连接之前执行ping操作 在使用连接之前,可以先执行一个pi...

客户希望设置参数,将长时间的空闲连接断开,这里涉及到interactive_timeout和wait_timeout,这两个MySQL的默认值是28800(单位秒,对应8小时), 京东云控制台默认设置为86400(24小时)。 这两个参数字面含义如下: (1)interactive_timeout:服务器关闭交互式连接前等待活动的秒数,比如mysql客户端属于此类连接。 (2)wait_tim...

My preferred solution is to increase the wait_timeout to 86400 (24hr) on sessions from processes that are long lived. Otherwise I have to do a close before any blocking call to other systems, e.g. redis, which may block for a month or return in a split second. These blocking calls ...

Thanks for the quick response. I added the group eliminating the error. However, the expected result was to modify the wait_timeout. After restarting and verifying the variables, I found the the wait_timeout default value (28800) was not changed to the new 86400 value. Any ideas on how ...
