Use httpd to configure Server Load balancer for tomcat. Experimental System: CentOS 6.6 _ x86_64 Prerequisites: Prepare the compiling environment in advance, and disable both firewall and selinux. Tutorial Description: There are two hosts in this experiment, and IP addresses are allocated as topology. Experimental software: jdk-8u60-linux-x64 apache-tomcat-8.0.24

Redis/Distributed File Storage System/database storage session solves session inconsistency in the Server Load balancer cluster, redissession Let's talk about the similarities and differences between sessions and cookies. Session and cookie are not only stored on the server, but also stored on the client. Although the

The difference between Nginx load balancing and counter-selection agent?A: I think there is no difference, one is called reverse proxy, more than one is called load balancing, they are used togetherSecond, the Nginx load balancing principle650) this.width=650; "src=" Http://s4.51cto.com/wyfs02/M01/84/0B/wKiom1eEXQmxD3X8AAJFEphKtCY549.png "title=" lb.png "alt=" Wk

The front-end of an application is an nginx server. All static content is processed by nginx, all PHP requests are distributed to several downstream servers running the PHP FastCGI daemon. In this way, the system load can be apportioned in a cheap way, expand the load capacity of the system.The IP addresses of the three PHP FastCGI servers are:172.16.236.110, 172
