The invention discloses a media stream distribution method, a CDN node server, a CDN system and a readable storage medium. The media stream distribution method comprises the following steps: receiving a data packet of a media stream; writing the received data packet of the media stream into a shared memory; and in response to the request of the terminal user, reading the data packet of the media stream requested by the terminal user from the shared memory. According to the media stream distribution method provided by the invention, the technical problem that a large number of cache copies from a user mode to a kernel mode exist in a media stream distribution process according to the prior art is solved, the consumption of a system is reduced, the service capability of equipment is improved, and the cost of equipment configuration is further reduced. 本发明公开了一种媒体流分发方法、CDN节点服务器、CDN系统和可读存储介质。其中所述媒体流分发方法包括：接收媒体流的数据包；将接收的媒体流的数据包写入共享内存；以及响应终端用户的请求，从共享内存中读取所述终端用户请求的媒体流的数据包发包。本发明提出的媒体流分发方法解决了在根据现有技术的媒体流分发过程中，存在大量的用户态到内
