There are many Server Load balancer solutions. The haproxy + keepalived solution is used here. Introduction Haproxy Introduction Haproxy is a high-performance TCP/HTTP load balancing server software with fast speed and high availability. It is applicable to all TCP or HTTP-based applications, especially for busy Web Services. In today's mainstream server configur

Currently using a hardware load balancer as an Exchange deployment scenario, using a hardware load balancer a good advantage is that the load of the application can be distributed more evenly to the servers in each backend, there are two different modes of operation of the h

load balancing is mainly through the server node to install the device specifically for load balancing, such as F5, and software load balancing is to complete the request distribution work by installing some software with load balancing function or module on the server, such as Nginx, etc. Whether you are using hardwa

Apache HTTP Server is selected as the front-end Server Load balancer, and two Tomcat clusters are selected at the backend. The selected configuration method is session sticky (sticky session ), this method forwards requests from the same user to a specific Tomcat server to avoid session replication in the cluster. The disadvantage is that the user only communicates with one server, if the server is down, it

1) Open the "httpd.conf" file in the "/usr/local/apache2/conf" directory and add the following configuration item at the end of the file, as shown in Figure 4-2-1.

Clusters, such as buying a generation to push the server down and put a piece he's quite a cluster, and load balancing is to get this big bunch of servers to work on average. He is called load Balancer, as shown in:For example, I use 192.168.8.155 to act as a pic host 1 and PIC Host 2 with Server A, 192.168.8.166, and 192.168.8.177来 as follows:Then start modifyin

This article describes how to configure Simple Server Load balancer on Docker. The host machine is Ubuntu14.04.2LTS, two CentOS containers, Nginx for the host machine, and tomcat 7 for the two containers. The architecture is as follows: the principle of this solution is to map the host machine port and the docker container port (that is, a port accessing the host machine will be mapped to the corresponding
