nginx:报错upstream sent too big header(nginx 1.24)

一，报错信息:

访问网站时报错：如图:

查看nginx的错误日志:

2023/06/16 10:21:46 [error] 416087#0: *71148 upstream sent too big header while reading response 
    header from upstream, client: 223.72.69.14, server: blog.liuhongdi.com, 
    request: "GET /index.php/2023/06/11/go-fa-song-get-qing-qiu-bing-jie-xi-fan-hui-json-go1-16-4/ HTTP/1.1", 
    upstream: "fastcgi://127.0.0.1:9000", host: "blog.liuhongdi.com", 
    referrer: "https://blog.liuhongdi.com/"

二，解决:

编辑nginx.conf

在 php的配置中添加:

fastcgi_buffer_size 128k;
fastcgi_buffers 1024 32k;

说明：

fastcgi_buffer_size   默认值4k|8K，

读取 fastcgi 应答第一部分需要多大缓冲区

默认值太小，需要调大此数值

 fastcgi_buffers默认值 8 4k|8K

分配多少个缓冲区缓冲fastcgi的应答请求

完整的例子：

location ~ \.php {
                fastcgi_buffer_size 128k;
                fastcgi_buffers 1024 32k;
                fastcgi_pass   127.0.0.1:9000;
                fastcgi_index  index.php;
                fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include        fastcgi_params;
    }

重启nginx服务

[root@img conf]# systemctl restart nginx.service
