The present invention proposes a kind of Nginx configuration thermal update system and method based on DPDK technology, described system comprises: user mode, kernel mode and underlying hardware module; User mode comprises Nginx application layer, user mode protocol stack, DPDK driver layer; When When described system receives the modification instruction of user to Nginx original configuration file, will generate Nginx update configuration file, and produce corresponding Nginx configuration file update instruction; Receive described Nginx configuration file update instruction by the main process of user mode, and its Notify all work processes managed by the main process; each work process rereads the Nginx update configuration file and the Nginx original configuration file according to the Nginx configuration file update command; each work process compares the Nginx update configuration file with the Nginx original configuration file, and determines the difference information; the Nginx application layer closes the invalid listening port according to the difference information, and / or opens the newly added listening port. The invention can provide high-performance web service and reverse proxy service.
Description
technical field [0001] The invention relates to the technical field of DPDK, in particular to a DPDK-based Nginx configuration hot update system and method. Background technique [0002] The full name of DPDK is Date plane development kit, which is a software library used to accelerate packet data processing. DPDK uses polling instead of interrupts to process packets. When receiving a data packet, the network card driver overloaded by DPDK will not notify the CPU through an interrupt, but directly store the data packet into the memory, and deliver the application layer software to directly process through the interface provided by DPDK, which saves a lot of CPU Interrupt time and memory copy time. [0003] Nginx is a high-performance HTTP and reverse proxy web server. Nginx has the advantages of less memory and strong concurrency. In fact, the concurrency of Nginx is better than other web servers of the same type, and it has been widely used in the websites of Internet co...
