5. advanced lb Worker attributes:
JK 1.2.x adds two new attributes: local_worker_only and local_worker, which provide new load balancing and fault tolerance support for lb worker.
Let's take an actual environment as example:
A cluster has two nodes (worker1 worker2), one web server before and after tomcat workers, and one load
Build a Server Load balancer cluster with LVS in Linux
Common open-source load balancing software: nginx, lvs, and keepalivedCommercial Hardware load equipment: F5, Netscale1. Introduction to LB and LVSLB clusters are short for load
;Note: If you are running multiple tomcat at the same time on a single PC, you must set the port (port number) inside the "" element node of each tomcat pair's Server.xml file to a different value. Here the difference is only the second one, but the two " " element nodes need to be modified.Load Balancer cluster configuration (2):Then continue to modify this file, find the " " element node below the comm
Recently, when using Microsoft cloud, we found that azure launched the standard version of Server Load balancer, which should be good news for many users with high security requirements, you can configure SNAT.
With azure Server Load balancer, you can:

Server Load balancer (SLB) is a load balancing service that distributes traffic among multiple ECs instances. SLB can expand the external service capability of the application system through traffic distribution, and improve the availability of the application system by eliminating spof.

From the name subnet IP, you can assign an IP from the device's direct subnet, some of which are similar to the interface IP of some network devices, or the IP of the VLAN.The server's response is also under the same two paragraphs. The server responds to NetScaler SNIP, NetScaler finally uses the VIP response to the client.So netscaler in the middle, we don't
I. Concepts of reverse proxy and Server Load balancer
Before understanding the concepts of reverse proxy and Server Load balancer, we must first understand the concept of a cluster. Simply put, a cluster is a server that does the same thing, such as a web cluster, database cluster, and storage cluster, the cluster has
Some time recently, we started touching on load balancing, from hardware F5 to Citrix Netscalar. However, because the hardware configuration is not complicated, but the expensive price also makes the general user prohibitive (a hundred thousand of to hundreds of thousands of), so can only turn to nginx,squid this kind has the reverse proxy function software.

Ii. Server Load balancer settings
WFS709TP supports adjusting Server Load
server {Listen 80;Server_name localhost;
Change the content to the following:
Server {Listen 80;Server_name 10.60.44.126;
(This is a request to listen to the access domain name bound to port 80 of the server)
Well, the configuration is as simple as this. The following figure shows the configuration of the above three steps:
