DESIGN AND IMPLEMENTATION OF A WEB SERVER FOR A HOSTING SERVICE

摘要

A web server named Harache is presented. The server runs under the authority of the file owner. Existing servers have problems that occur because of the user authority during execution. When a program that uses a server embedded interpreter, for example PHP, creates data files, the owner of the created files is the special user account that runs a server. Therefore, other users that share the same server can steal and delete these data files. In particular, these problems are serious for a hosting service where many users share a server. Harache has server processes that run under the authority of the file owner. Therefore, Harache can solve these problems that occur because of the user authority. Harache can be used for a hosting service where many people share a server with a reverse proxy. We implemented Harache on a Linux OS with SELinux and performed evaluation experiments to test the system's effectiveness. Experimental results show that Harache has high performance and scalability.
