Recently, the program encounter ed a problem, LNMP environment, because PHP in the program spliced GET request uri parameter is too long, resulting in an error, nginx processing uri is too long can be processed by client_head_buffer_size parameter, but when nginx received the uri request forward to PHP, fastcgi can not handle the request error (do not consider changing the request to post).
System：linux CentOS7 nginx：1.14.0 php：7.2.0
Apache solution:
Add a few parameters to the configuration file
LimitRequestLine 40940
LimitRequestFieldSize 40940
Nginx solution:
**How to increase the limit of fastcgi to accept uri parameter size?**
