前段时间做一个项目，需要上传文件，差不多需要20M左右，普通用php处理会比较麻烦，经常超时，而且大量占用资源。于是搜索了下，决定用nginx的upload上传模块来处理。
你可以在这里：http://www.grid.net.ru/nginx/upload.en.html 获取源码。下载以后需要重新编译nginx

./configure –add-module=/usr/local/nginx_upload_module-*makemake install |
重启nginx即可
以下是我的nginx配置文件
前端页面提交的时候直接提交到 http://test.local/upload 即可

upload_pass 指明了需要后续处理的php地址upload_cleanup 如果php出现400 404 499 500-505之类的错误，则删除上传的文件upload_store 上传文件存放地址upload_store_access 上传文件的访问权限，user:r是指用户可读upload_limit_rate 上传限速，如果设置为0则表示不限制upload_set_form_field 设定额外的表单字段。这里有几个可用的变量：$upload_file_name 文件原始名字$upload_field_name 表单的name值$upload_content_type 文件的类型$upload_tmp_path 文件上传后的地址upload_aggregate_form_field 额外的变量，在上传成功后生成$upload_file_md5 文件的MD5校验值$upload_file_size 文件大小upload_pass_form_field 从表单原样转到后端的参数，可以正则表达式表示官方的例子是upload_pass_form_field "^submit$|^description$";意思是把submit，description这两个字段也原样通过upload_pass传递到后端php处理。如果希望把所有的表单字段都传给后端可以用upload_pass_form_field "^.*$"; |
