radware load balancer

Objective: to use apache and tomcat to configure a web site that can be applied, you must meet the following requirements: 1. use Apache as an HttpServer, and connect multiple tomcat application instances to achieve load balancing. 2. set the Session timeout for the system... objective: to use apache and tomcat to configure a web site that can be applied, you must meet the following requirements: 1. use Apache as an HttpServer, and connect multiple to

1. Use Nginx Ip_hash as Load Balancer Service and support session sticky2, using nginx sticky third-party module to achieve cookie-based load balancing3, using the Nginx map instruction according to the cookie shunt:Map $COOKIE _abcdexpid $group { ~*1$apache001; ~*2$apache002; Defaultroot;} Upstream apache001 { server 192.168.1.1:8080 weight=1 Max_fails=1 fai

1 , LVS , TUN IntroductionLVS is a Linux Virtual Server in the actual environment, often as b/S structure of the network application in the load balancer to use, working in 7 Layer network model, the network layer, which is usually said IP layer, because the data is processed in Linux The kernel state is complete, so the relative reverse proxy server, the performance is generally higher;TUN is a IP Tunnelin

Transparent load Balancer http forward Proxy* Master-workers architecture, HTTP positive justification for separate DNS requests and buffering processes* Using the Epoll (ET) mode, the full asynchronous approach (dual cache, to achieve two-way simultaneous forwarding);* Event management mechanism (event pool, event object separation)* Use red black tree timeout management* Flexible and simple configuration

Docker + nginx + Tomcat 7 Simple Server Load balancer ConfigurationThis article describes how to configure Simple Server Load balancer on Docker. The host machine is Ubuntu 14.04.2 LTS, two CentOS containers, Nginx installed on the host machine, and tomcat 7 installed on the two containers. The architecture is as follo

I. LVS principles 1. The full name of LVS is Linux Virtual Server, that is, Linux Virtual Server. It is an open-source project of Dr. Zhang Wenyu from our country. In linux memory 2.6, it has become a part of the kernel. in earlier versions, the kernel needs to be re-compiled ., LVS is mainly used for multi-server load balancing. It works at the network layer to implement high-performance and high-availability server cluster technology. It is cheap an
