问题描述
我有一个运行时间较长的PHP脚本.我正在脚本的最开始进行数据库连接，并在启动时进行了一些数据库操作.
I have a long running PHP script. I am making the database connection at the very beginning of the script and does some database operation at the start up.
此后，脚本执行了4个小时的PHP操作，即使一次也没有通过该连接ping通MySQL.
After that, the script perform 4 hours of PHP operation without pinging to MySQL with that connection even a single time.
在这些长时间运行的PHP操作结束时，当我尝试执行mysql_query时，出现以下错误:MySQL Server has gone Away
At the end of these long running PHP operations, when I try to execute mysql_query it gives me the following error: MySQL Server has gone Away
是否有可能将连接超时增加到4小时?我正在使用PHP ADODB从我的PHP应用程序与MySQL连接.
Is there any possibility of increasing the connection timeout to be 4 hours? I am using PHP ADODB to connect with MySQL from my PHP application.
请提出建议?
推荐答案
MySQL的超时不同于PHP.您可以在php.ini行的mysql.connect_timeout = 14400中增加它.同时增加default_socket_timeout = 14400
MySQL has a different timeout than PHP. You could increase it in php.ini on the line mysql.connect_timeout = 14400. Also increase the default_socket_timeout = 14400
请注意，如果您的PHP设置允许您执行ini_set，则还可以执行以下操作:
Note that if your PHP setting allow you to do an ini_set, you can also do as follows:
ini_set('mysql.connect_timeout', 14400);
ini_set('default_socket_timeout', 14400);
