How to integrate Kafka with Nginx

Background nginx-kafka-module is a plug-in for nginx. It can integrate kafka into nginx to facilitate the collection of front-end page buried point data in web projects. If the front-end page has set up buried points, some of the user's access and request data can be collected. The HTTP request is sent directly to the message middleware Kafka, and the backend can consume the messages in Kafka through the program to perform real-time calculations. For example, sparkstream is used to consume data in Kafka in real time to analyze user pv, uv, some user behaviors and the funnel model conversion rate of the page, so as to better optimize the system or conduct real-time dynamic analysis of visiting users. Specific integration steps 1. Install git

Summary When Nginx performs reverse proxy, it will perform domain name resolution, resolve the domain name to a specific IP and cache it locally. If the IP corresponding to the domain name changes, it will cause the Nginx proxy to fail. The Nginx resolver directive is used below to implement domain name dynamics. parse. Dynamically resolve the intranet DNS server based on a custom DNS server.

How to configure and optimize FastCGI in Nginx

fastcgi: fastcgi is developed and improved from cgi. The main disadvantage of the traditional cgi interface method is poor performance, because every time the http server encounters a dynamic program, the script parser needs to be restarted to perform parsing, and then the results are returned to the http server. This is almost unavailable when dealing with high concurrent access. In addition, the traditional cgi interface method has poor security and is rarely used now. The fastcgi interface mode adopts the c/s structure, which can separate the http server and the script parsing server, and start one or more script parsing daemons on the script parsing server. Every time the http server encounters a dynamic program, it can be delivered directly to fastcg

How to solve nginx+php-fpm service HTTP status code 502

For one of our web projects, due to the increase in new cities, the number of visits has increased and the pressure on the db has increased. As a business party that provides interfaces, a large number of "502" requests have been reported recently by downstream feedback. 502, badgateway, is usually an error in upstream (here is PHP). For PHP, the common cause of 502 is that the script execution exceeds the timeout setting time, or the timeout setting is too large, resulting in the PHP process not being released for a long time, and there are no idle workers. process to pick up guests. Our project is caused by the PHP execution time setting being too short. In this case, you can first increase the PHP execution time appropriately and ensure that 502 is cleared first. Optimization will cost more after all.
