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

还有人说是这个原因
最后大家说是由于被黑客攻击了:
解决方法:
1. 修改root密码
2. 限制ip访问
