ngx_upload模块是nginx中一个文件上传模式了，下面我们来看看nginx安装文件上传ngx_upload模块步骤，希望例子对各位有帮助.
安装nginx，并加入nginx upload module和nginx cache purge module:
mkdir ~/download
cd ~/download
wget .ru/nginx/download/nginx_upload_module-2.0.12.tar.gz
tar zxf nginx_upload_module-2.0.12.tar.gz
git clone https:///FRiCKLE/ngx_cache_purge.git
yum groupinstall "Development Tools"
yum install pcre-devel zlib-devel openssl-devel
wget /download/nginx-1.2.3.tar.gz
tar zxf nginx-1.2.3.tar.gz
cd nginx-1.2.3
./configure --prefix=/usr/local/nginx --with-pcre --with-http_ssl_module --add-module=../nginx_upload_module-2.0.12 --add-module=../ngx_cache_purge
make && make install
尝试启动：
/usr/local/nginx/sbin/nginx
ps aux | grep nginx
假如我的网站是放在 /home/mysite/www 下的，而nginx配置文件就放在 /home/mysite/etc 下：
省略了很多内容的配置文件，mysite.conf：
server {
listen 80;
server_name 192.168.1.123;
client_max_body_size 20M;
location /upload {
include /home/mysite/etc/nginx/ngx_upload.conf;
}
....其他的配置....
location @after_upload {
proxy_pass www_backend;
}
}
将nginx_upload.conf独立开来，是因为其他网站也可以包含此上传配置文件：
nginx_upload.conf：
upload_pass @after_upload;
upload_pass_args on;
upload_cleanup 400 404 499 500-505;
upload_store /home/mysite/www/uploads/tmp;
upload_store_access user:r;
upload_limit_rate 128k;
upload_set_form_field "${upload_field_name}_name" $upload_file_name;
upload_set_form_field "${upload_field_name}_content_type" $upload_content_type;
upload_set_form_field "${upload_field_name}_path" $upload_tmp_path;
upload_aggregate_form_field "${upload_field_name}_md5" $upload_file_md5;
upload_aggregate_form_field "${upload_field_name}_size" $upload_file_size;
upload_pass_form_field "^.*$";
而最后那个参数：upload_pass_form_field，代表可以将表单的所有参数保持原样传递到后端，需要区分文件保存类型时很有用。
