balancemember are members in the cluster. Port 8009 is the AJP port name of Tomcat. The above amendment: This was neglected during the test yesterday and was discovered only during the test at the company today. You must note that route = worker1 and route = worker2 in the balancermember line cannot be added. Once added, distributed access will not be performed through the Apache designation, therefore, you must remove it here. Otherwise, operations will only be performed in a tomcat container.

I. IntroductionLinux Virtual Server (LVS) is a Virtual Server in Unix-like systems and one of the most outstanding projects contributed to open-source organizations in China. LVS exists as a front-end (ctor) in Unix-like systems and is also called a scheduler. It does not provide any services, only requests that come in through the Internet are accepted and then forwarded to the real server running in the b

The first part of the Web layer balanced loadUnder the. NET platform, there are two ways (IIS7 and nginx) for the balanced load that I have deployed, and the following is an example of nginx to explain the balanced load of the web layer.Introduction: Nginx beyond the performance and stability of Apache, so that the domestic use of Nginx as a Web server website is also more and more, including Sina Blog, Sin
