注意上传大文件nginx需要做如下配置

找到自己主机的nginx.conf配置文件，打开
在http{}中加入
    #客户端文件上传的大小
    client_max_body_size 500m;
    #用于tomcat反向代理,解决nginx 504错误 
    proxy_connect_timeout 300; #单位秒 
    proxy_send_timeout 300; #单位秒 
    proxy_read_timeout 300; #单位秒 
    proxy_buffer_size 16k; 
    proxy_buffers 4 64k; 
    proxy_busy_buffers_size 128k; 
    proxy_temp_file_write_size 128k;
    # ps:以timeout结尾配置项时间要配置大点
然后重启nginx
