Server Load balancer solutions include hardware and software solutions. Mainstream hardware solutions: F5 BIG-IP Citrix netscalar A10 A10 Array Redware LVS (Linux virtual server) is a layer-4 network switching or routing software solution. It implements switching or routing through kernel framework module ipvs and a set of rules configured on the framework

Part 2 middle layer Server Load balancer WCF In the first part of the article, I briefly introduced how to perform load balancing on the web layer. The main software used is nginx. Why is the concept of the intermediate layer referenced here? The simplest deployment method is web layer-> access to DB. The direct database connection method here is the layer-2 a

In Linux Streaming Server Load balancer, Layer7 identifies data streams (Connection Tracking ).1. the nf_conntrack that supports Layer7 does not really need to be destroyed. After that, you will feel that you need to change "data streams based on quintuple" to "data streams with fixed offsets based on application layer protocols, the sooner the better! Therefore, this person added several fields for nf_conn

Identification of Layer7 data streams (Connection Tracking) in Linux Streaming Server Load balancer 1. nf_conntrack supporting Layer7 is really unnecessary After the fire, you will feel the need to quickly change "data streams based on quintuple" to "data streams with fixed offset based on the application layer protocol". The sooner the better! Therefore, this person added several fields for nf_conn in the

When deploying the project, 2 servers were used. The request was loaded with load balancing, resulting in YII2 static files (js,css ...) Reported 404, The reason is: the request for a page when a server to process, but the static resource is missing the request to the B server, B server's YII2 resource manager has not been generated in the Web\assets directory and static files. Take a closer look at the static resource Management code for YII2: yi
