Nginx works in a multi-process manner, with a master process and multiple worker processesThe master process is used to manage worker processes(1) Send a signal to each worker process(2) Monitor worker processes, and when a worker process has an exception, a new worker process is started.The master process will first establish a socket,fork function to listen to the generation of sub-process workers, inherit scoket, generally speaking, when there is a

Memcached and nginx concurrency models, one is a model of single-process and multi-thread, and the other is a classic multi-process and single-thread model. By comparison, we will deepen our understanding of the two concurrency models. First, analyze the application scenarios of the two. Commonalities: Two applications, one is the cache service and the other is the Web service. They are applications that ha

The Tomcat cluster session synchronization scheme is available in several ways: With the cluster method of Tomcat, it is easy to configure the session information automatically in real-time with multiple tomcat. However, this scheme is inefficient and does not perform well in large concurrency. Principle: http://zyycaesar.iteye.com/blog/296606 Using Nginx's IP-based hash routing strategy, it is easier to ensure that IP access is always routed to the same tomcat. But if th

1 cause Recently, a stress test was conducted on the newly developed web system, and it was found that the response speed of concurrent logon home pages under Tomcat's default configuration pressure to 600 people was severely affected, more than 2000 errors of 500 and 502 occur in one round. I made a look at the logon time statistics and printed out the total server processing time. I saw that some responses were indeed within 20 seconds, however, the average time is far different from that test

/test.jsp, when different host accesses are scheduled to be processed on different Tomcat instancesrequests from the same host are handled by the same Tomcat instance , where you drop the currently responding Tomcat Realexample , Nginx automatically dispatches the user's request to another Tomcat instance , and the session is not discarded.
