72.nginx文件配置

1.nginx上传文件:

1)
Syntax:	client_max_body_size size;
Default:	client_max_body_size 1m;  # 默认值1m代销
Context:	http, server, location   # 可以配置的范围
Sets the maximum allowed size of the client request body, specified in the “Content-Length” request header field. If the size in a request exceeds the configured value, the 413 (Request Entity Too Large) error is returned to the client. Please be aware that browsers cannot correctly display this error. Setting size to 0 disables checking of client request body size.  # 最后一句话很关键,设置为0之后就不显示客户端上传大小,同时记住超过限制之后的报错信息可能会显示其他报错信息,比如跨域报错等等

client_max_body_size 1024M; 上传文件大小限制

2)
Syntax:	keepalive_timeout timeout [header_timeout];  # 连接保持时间
Default:	keepalive_timeout 75s;   # 默认75秒钟,但是一般都会调的比较小,特殊网站除外
Context:	http, server, location
The first parameter sets a timeout during which a keep-alive client connection will stay open on the server side. The zero value disables keep-alive client connections. The optional second parameter sets a value in the “Keep-Alive: timeout=time” response header field. Two parameters may differ.
    
keepalive_timeout 1800;保持连接的时间，默认65s

3)
sendfile on; 设置为on表示启动高效传输文件的模式   # DMA表示直接存储访问
