mysql提示Packet for query is too large (1142 > 1024)解决方案

注:最近mysql一直提示如下错误

 Packet for query is too large (1185 > 1024). You can change this value on the server by setting the max_allowed_packet' variable.

按网上要求,检查max_allowed_packet

show VARIABLES like '%max_allowed_packet%';

修改max_allowed_packet

set global max_allowed_packet = 2*1024*1024*10

或者修改配置文件my.ini(windows)/my.cnf(linux)

max_allowed_packet = 20M

重启
