nginx 报错 upstream timed out (110: Connection timed out)解决方案

nginx 作PHP的web接口服务器。

在线上发现时不时经常崩溃。504，导致接口访问无响应回复。

查看日志：

[error] 11618#0: *324911 upstream timed out (110: Connection timed out) while reading response header from upstream, 
client:
然后百度看到都是修改nginx配置，解决超时问题、

large_client_header_buffers 4 16k;
client_max_body_size 30m;
client_body_buffer_size 128k;
#proxy_connect_timeout 300;
#proxy_read_timeout 300;
#proxy_send_timeout 300;
#proxy_buffer_size 64k;
#proxy_buffers   4 32k;
#proxy_busy_buffers_size 64k;
#proxy_temp_file_write_size 64k;

fastcgi_connect_timeout 300;
fastcgi_read_timeout 300;
fastcgi_send_timeout 300;
fastcgi_buffer_size 64k;
fastcgi_buffers   4 32k;
fastcgi_busy_buffers_size 64k;
fastcgi_temp_file_write_size 64k;

根据自己服务器配置来选择以上配置。fastcgi 选择fastcgi。要放在server节内。

线上服务器已配置好，等待验证是否无此错误。、、、
