[svc]nginx限制客户端上传附件的大小
300 行 python 代码的轻量级 HTTPServer 实现文件上传下载
- 系统环境
[root@n1 conf]# cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)[root@n1 conf]# python --version
Python 2.7.5- 直接运行访问即可 http://192.168.2.11:12345
- 准备nginx反代环境
user www www;
worker_processes 1;
error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {worker_connections 1024;
}
http {include mime.types;default_type application/octet-stream;#log_format main '$remote_addr - $remote_user [$time_local] "$request" '# '$status $body_bytes_sent "$http_referer" '# '"$http_user_agent" "$http_x_forwarded_for"';#access_log logs/access.log main;sendfile on;#tcp_nopush on;#keepalive_timeout 0;keepalive_timeout 65;#gzip on;server_tokens off;upstream upload_file {server 127.0.0.1:12345;}server {listen 80;server_name upload.maotai.com;location / {proxy_next_upstream error timeout invalid_header http_500 http_503 http_404 http_502 http_504;proxy_pass http://upload_file;proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;}}
}后启动,在主机上加hosts. 访问 upload.maotai.com
- 传输一个较大的文件上去(30M),发现报错
如果优化版本后,就不会暴漏nginx了. 我改为了(毛台ws, MTWS)
- 查看nginx错误日志
[root@n1 nginx]# tail -f logs/error.log
2018/03/11 09:17:34 [error] 12202#0: *8 client intended to send too large body: 32556632 bytes, client: 192.168.2.1, server: upload.maotai.com, request: "POST / HTTP/1.1", host: "upload.maotai.com", referrer: "http://upload.maotai.com/"修改nginx.conf-解决问题
http{...client_max_body_size 1000m;
