kong配置调整方式

kong logs/error.log内确实发现大量日志

2021/01/25 16:46:05 [warn] 166110#0: *3522559308 a client request body is buffered to a temporary file /usr/local/kong/client_body_temp/0000015840, client: , server: kong,

a client request body is buffered to a temporary file /usr/local/kong/client_body_temp/0000015840, client: , server: kong
该报警要调整nginx 的client_body_buffer_size，默认为client_body_buffer_size 8k|16k;

因为kong是在nginx上封装的，因此改kong的配置和nginx不完全一样

按常规思路直接修改konga生成的nginx.conf是不生效的

而kong reload后nginx.conf会被重置

因为kong生成的nginx.conf文件主配置是在kong start时加载 /etc/kong/kong.conf 和一些信息，生成的，因此调整需更改

/etc/kong/kong.conf 调大client_body_buffer_size

client_body_buffer_size = 500k    # Defines the buffer size for reading the
                                 # request body. If the client request body is
                                 # larger than this value, the body will be
                                 # buffered to disk. Note that when the body is
                                 # buffered to disk Kong plugins that access or
                                 # manipulate the request body may not work, so
                                 # it is advisable to set this value as high as
                                 # possible (e.g., set it as high as
                                 # `client_max_body_size` to force request
                                 # bodies to be kept in memory). Do note that
                                 # high-concurrency environments will require
                                 # significant memory allocations to process
                                 # many concurrent large request bodies.

测试 类似 nginx -t

kong check
configuration at /etc/kong/kong.conf is valid

重新加载 类似 nginx -s reload

kong reload

如此 配置生效，问题解决
