问题 I'm working on a website that deals with a lot of images. Users will have the ability to upload images. Images would be hosted on a separate remote Nginx server. What is the best way to create directories and upload images to the remote server? Would SSH be a viable option? anything better? The web application is created with Spring Boot 回答1: SSH won't really do anything to help you share or sync files across a network. Based on your tag (linux) I suspect you could install the nfs-kernel

问题 I am running MarkLogic 7 on a CentOS 6.5 box . I have my HTML/JS application hosted on a MarkLogic HTTP server on the same machine. The application runs on port 8003, and needs to access data through a REST API running on a different port 8007. When I use an AJAX request in my application, I get an error saying No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://172.16.100.104:8003' is therefore not allowed access. Has anyone set up MarkLogic for CORS
