Operating System: Debian 3.0 r2 Kernel used: linux-2.4.23 The module used in the experiment: ipvsadm-1.21, PostgreSQL (detailed usage of ipvsadm command please refer to here) Function Description: This is a simple experiment on linuxvirtualserver. It is about how to achieve load balancing between two PostgreSQL databas

Server Load balancer is a server set composed of multiple servers in a symmetric manner. Each server is equivalent and can provide services independently without the assistance of other servers. Through a load balancing technology, requests sent from outside are evenly distributed to a server in the symmetric structure, and the server receiving the requests indep

we are talking about Load balancer, sometimes called a four-tier load balancer or seven-tier load balancing device, sometimes called a four-layer switch or seven-layer exchange. The four-layer load balancing device mainly analyzes

What is LVS??? Let's start with a brief introduction to LVS (Linux Virtual Server), which is actually a cluster (Cluster) technology that uses IP load balancing technology and content-based request distribution technology. The scheduler has a good throughput rate, transfers the request evenly to the different server execution, and the scheduler automatically shields off the server's failure, thereby forming
