大神们,我现在有个问题,帮我看下:
因为使用nginx均衡负载,由于分发请求到不同服务器,这样如果只想把上传的图片只保存到一台服务器就会出问题。
百度到的方法:
第一种方法是代码里面使用ftp 把文件同步到保存服务器
第二种方法是如果不是保存文件的服务器,使用curl 把文件提交到保存服务器再重新存一次。
第三种方法就是直接使用保存服务器的ip来调接口了。第三种方法我们这边先不考虑。
不知道大神们,遇到这种情况是怎么实现这种需求的

宿主的nginx对于上传的location做特殊处理, 只让一台机器来负责文件上传, 不完美但是有效, 可以作为一段时间的过度方案
搭建一个分布式文件系统, 挂载到所有的服务器上, 处理文件上传后写只写入这个特定目录, nginx中规划一个location指向这个这个目录(例如/data/upload), 缺点就是要多维护一个这个分布式文件系统 (和你的第一种思路有点像, 但分布式文件系统不需要"同步")
使用外部CDN文件上传来解决这个问题, 七牛, 又拍云都可以
1.专门整几台服务器用来存这些静态资源;
2.整出几个盘,弄成网络盘(nfs),专门用来存储这些文件,每个服务器都去挂载这几个盘,和windows的共享文件夹类似;
3.上传成功之后返回一个文件的url,这个url就是文件的地址了;

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
