show VARIABLES like '%max_allowed_packet%';
显示的结果为:
+--------------------+---------+ | Variable_name | Value | +--------------------+---------+ | max_allowed_packet | 1048576 | +--------------------+---------+
以上说明目前的配置是:1M
当偶在my.cof文件里面设置
max_allowed_packet = 20M
重启后就可以了,但是过一段时间,他自己有变成了初始值,每次出现这样的问题都需要重启,
实在麻烦,有没有办法设置好后,就不要在设置的,
请大神指教
one on the client side : [mysql] section, [mysqldump], [client] and more.
one on the server side : [mysqld] section.
The value of max_allowed_packet you see with the command show variables like 'max_allowed_packet'; is the one on the server side.
In order to increase this value, you must increase both sides : in your server configuration file ([mysqld] section in your my.ini file) and in your client configuration file (whether your [client] or [mysql] section in your my.ini file).
